J Cataract Refract Surg 2024; 50:993-999. [PMID: 38915155 DOI: 10.1097/j.jcrs.0000000000001509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 06/13/2024] [Indexed: 06/26/2024]
Abstract
PURPOSE To evaluate microbiological cultures of cataract surgical devices and products that were reused for multiple cases. SETTING Aravind Eye Hospital, Pondicherry, Tamil Nadu, India. DESIGN Prospective cohort study. METHODS Samples from multiple surgical instruments and products that were reused for consecutive cataract surgeries underwent bacterial and fungal cultures and were monitored alongside positive controls for 7 days. This included instruments that were processed using immediate use steam sterilization (IUSS) between cases (eg, surgical cannulas, syringes, phacoemulsification and coaxial/bimanual irrigation/aspiration [I/A] tips, phacoemulsification and I/A sleeves) (Group 1), instruments that were used without sterilization between cases (eg, phacoemulsification tubing/handpieces, coaxial I/A handpieces) (Group 2), and the residual (unused) fluid from balanced salt solution bags after being used for multiple patients (Group 3). RESULTS 3333 discrete samples were collected from all 3 product groups that were reused across multiple patients. In all collected samples, no bacterial or fungal growth was observed. Of the 3241 cataract surgeries that used reused and IUSS-sterilized instruments alongside instrument sets cultured on the same day and balanced salt solution bags shared across multiple patients, no eyes developed endophthalmitis over a 6-week follow-up period. CONCLUSIONS Bacterial or fungal growth was not found in extensive microbiological cultures of IUSS-sterilized ophthalmic surgical instruments and cataract surgical products that were reused in multiple patients. This microbiological data complements clinical endophthalmitis data from 2 million consecutive cases at the Aravind Eye Hospital, suggesting that their instrument and surgical supply processing practices may allow for safe and sustainable ophthalmic care.

Abstract
PURPOSE We investigated potential risk factors for visual prognosis in Japanese patients with exogenous endophthalmitis. METHODS In this retrospective observational multicenter cohort study, risk factors for legal blindness at 12 weeks after treatment initiation were evaluated based on patient characteristics, initial BCVA, causative events, pathogens, ocular symptoms, duration from symptom onset to initial treatment, and selected treatments. RESULTS Overall, 23.1% of eyes developed legal blindness. The six risk factors for legal blindness were presence of eye pain, pathogen identification, poor BCVA at the initial visit, longer duration from symptom onset to initial treatment, type of causative event, and type of causative pathogen. Regarding the type of causative pathogen, coagulase-negative staphylococci was associated with a better visual impairment outcome. CONCLUSION Exogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatment, as well as other advances in medical knowledge and technology.

JAMA Ophthalmol 2024; 142:827-834. [PMID: 39088207 PMCID: PMC11295066 DOI: 10.1001/jamaophthalmol.2024.2749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Accepted: 06/03/2024] [Indexed: 08/02/2024]
Abstract
Importance Long-term trend analyses of overall endophthalmitis rates and treatment patterns are scarce. It is also unknown if the deviation from the recommendations of the Endophthalmitis Vitrectomy Study toward decreased utilization of vitrectomy is associated with different vision outcomes. Objective To determine whether the rate of endophthalmitis after intraocular procedures or the primary treatment (prompt vitrectomy vs tap and inject) for endophthalmitis has changed over the past 20 years. Design, Setting, and Participants This cohort study examined data for cohorts created by querying for different intraocular procedures, including intravitreal injections and surgeries for cataract removal, glaucoma, retinal conditions, and corneal transplants from 2000 to 2022. The data source was a US administrative medical claims database comprising commercial and Medicare Advantage insurance plans. Any intraocular procedure with at least 6 months of data available before and 6 weeks after the procedure was eligible. Exclusion criteria consisted of any previous diagnosis of endophthalmitis or another intraocular procedure during the follow-up period. Main Outcome Measure The main outcomes were rate of postprocedure endophthalmitis and relative rate of prompt vitrectomy (vs tap and inject) as the primary method of treatment. Results Among 2 124 964 patients, the mean (SD) age was 71.4 (10.2) years; 1 230 320 were female and 894 414 male. Over 22 years, 5 827 809 intraocular procedures were analyzed with 4305 cases of endophthalmitis found for an overall endophthalmitis rate of 0.07%. The yearly rate of endophthalmitis varied but generally declined from a high of 7 cases per 3502 procedures (0.20%) in 2000 to a low of 163 cases per 332 159 procedures (0.05%) in 2022. The percentage of cases treated with prompt vitrectomy also varied but generally declined over time with a high of 17 of 35 (48.6%) in 2003 and a low of 60 of 515 (11.6%) in 2021. Multivariable analysis of the endophthalmitis incidence rate ratio (IRR) showed a per-year decrease of 2.7% (IRR, 0.97; 95% CI, 0.97-0.98; P < .001) over the study period. A similar analysis also showed that the incidence rate of prompt surgical treatment decreased by 3.8% per year throughout the study period (IRR, 0.96; 95% CI, 0.95-0.97; P < .001). Conclusions and Relevance This study found that the incidence of endophthalmitis following intraocular procedures appears to have decreased substantially over the past 20 years while prompt vitrectomy is being used less frequently as primary treatment than in the past.

Abstract
OBJECTIVE To analyze the effect of gentamicin in the irrigating solution on endophthalmitis caused by methicillin-resistant Staphylococcus epidermidis after phacoemulsification with intraocular lens implantation. METHODS Fifteen rabbits were randomly assigned into three groups. During surgery, group A was irrigated with gentamicin-free solution and injected with 100 μL of normal saline postoperatively, group B was irrigated with 80 μg/mL gentamicin and injected with 100 μl of MRSE suspension, group C was irrigated with gentamicin-free solution and injected with 100 μl of MRSE suspension. At different times, corneal endothelial cell count (CEC), inflammation grading,B-scan ultrasonography and histological examination were analyzed. RESULTS No endophthalmitis occurred in groups A and B. Group C developed severe endophthalmitis, with massive inflammatory exudation in the vitreous cavity. CONCLUSION Irrigating solution containing gentamicin is favorable to reduce the incidence of MRSE endophthalmitis after phacoemulsification with IOL in rabbits.

Abstract
PURPOSE Postoperative endophthalmitis is a devastating complication, leading to poor visual prognosis. The purpose of this study is to determine the incidence, risk factors, and visual outcome of post-cataract surgery endophthalmitis in Malaysia over a 9-year period (2012-2020). METHODS Data from National Eye Database (NED), involving all patients who have undergone cataract surgery from January 2012 until December 2020 were analyzed. RESULTS Total number of patients who had undergone cataract surgery between the year 2012 till 2020 were 231,281 patients (267,781 eyes). Incidence of POE in this population was 0.08%. Patient aged 70 and above (p-value 0.047), Malay ethnicity (p-value: 0.009), presence of ischemic heart disease, renal failure, diabetic retinopathy, and poorer preoperative vision were shown to have a higher risk of POE. Cataract surgeries done in KK-KKM, duration more than 45 minutes, use of general anaesthesia, and no IOL or ACIOL implantation were significantly more in POE patients. Multivariate analysis revealed Malay ethnicity, presence of ocular comorbidity, poor preoperative vision, ACIOL, and presence of intra-operative complication were predictive factors for POE. CONCLUSIONS Incidence of POE is low in the Malaysian population. Surgeons have to be aware that Malay ethnicity, presence of ocular comorbidity, poor preoperative visual acuity, placement of IOL and complicated cataract operation have higher risk of POE.

Do Treatment Patterns for Endophthalmitis after Cataract Surgery Follow the Endophthalmitis Vitrectomy Study Recommendations?: An Academy IRIS® Registry Analysis. Ophthalmol Retina 2024:S2468-6530(24)00337-3. [PMID: 39048058 DOI: 10.1016/j.oret.2024.07.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 07/15/2024] [Accepted: 07/16/2024] [Indexed: 07/27/2024]
Abstract
OBJECTIVE To evaluate whether treatment patterns for endophthalmitis after cataract surgery in American Academy of Ophthalmology IRIS® (Intelligent Research in Sight) Registry patients are in line with evidence-based guidelines established by the 1995 Endophthalmitis Vitrectomy Study (EVS), which showed that patients who present with light perception (LP) vision have better visual outcomes with immediate vitrectomy (VIT) compared with vitreous tap with antibiotic injection (TAP). DESIGN Retrospective cohort study. SUBJECTS Intelligent Research in Sight Registry patients undergoing cataract surgery between 2014 and 2022 (identified by Current Procedural Terminology codes), presenting with endophthalmitis (identified by International Classification of Diseases 10 codes) within 42 days postcataract surgery, and having a record of being treated with VIT or TAP on the same or 1 day after endophthalmitis diagnosis were identified. METHODS Potential covariates of age, sex, race, ethnicity, geographic region, insurance status, and visual acuity on the day of endophthalmitis diagnosis were evaluated using multivariable logistic regression. MAIN OUTCOME MEASURES Treatment with VIT or TAP. RESULTS Of the 2425 patients who met the inclusion criteria, 14% (345) underwent VIT and 86% (2080) underwent TAP. Notably, 80% of patients (1946) presented with endophthalmitis within 14 days from cataract surgery (median = 6 days). Notably, 66% (173/263) of the patients presenting with LP vision underwent TAP instead of VIT. In a multivariable logistic regression model, receiving VIT instead of TAP was positively associated with poor vision at endophthalmitis presentation (LP - odds ratio [OR] = 5.4; confidence interval [CI], 2.9-10.6; counting fingers, hand motions - OR = 1.9; CI, 1.1-3.6) versus (20/20-20/40) vision; Asian versus White race (OR = 2.6; CI, 1.3-5.2); Hispanic versus non-Hispanic ethnicity (OR = 1.9; CI, 1.1-3.2); living in the West (OR = 1.6; CI, 1.1-2.2) and Midwest (OR = 1.5; CI, 1.1-2.0) (vs. South), but not with age, sex, and insurance coverage (P > 0.05). CONCLUSIONS In the IRIS Registry, treatment patterns for postcataract surgery endophthalmitis did not match evidence-based recommendations of the EVS, a randomized controlled clinical trial. More work is needed to evaluate whether the current treatment patterns are optimal for patients with postcataract surgery endophthalmitis.

Abstract
Aims This study is designed to generalize and depict the research hotspots of endophthalmitis through bibliometric methods and software and analyze the evolutive tendency of the work on this severe disease over the past 30 years. Methods This study employed a rigorous bibliometric approach. We identified all endophthalmitis-related literature by conducting a comprehensive search of the Science Citation Index Expanded database under the Web of Science Core Collection. The data was then analyzed and visualized using CiteSpace and VOSviewer, two widely recognized software tools in the field of bibliometrics. CiteSpace was used to analyze the country distributions, dual map overlay of journals, keyword bursts, and co-cited references. VOSviewer was employed to describe the authors and co-cited authors, the journals, the co-cited journals, and the keywords co-occurrence network. This robust methodology ensures the reliability and validity of the study's findings. Results A total of 2960 publications, including 2695 articles and 265 reviews, were included in this bibliometric study. There has been no shortage of endophthalmitis-related publications since 1993, with an apparent upward trend during recent years. Possible correlations with the COVID-19 pandemic are also analyzed. These studies were finished by 11,048 authors from 75 countries worldwide, with the United States in the lead. In the keyword co-occurrence network, except for the endophthalmitis term, cataract surgery becomes the keyword with the highest frequency. Different categories of endophthalmitis, including postoperative, post-injection, post-traumatic, and endogenous endophthalmitis, and antibacterial and anti-inflammatory therapies of infectious endophthalmitis, are discussed by categories. From the perspective of the timeline, postoperative and post-injection endophthalmitis were the dominant forms before and after the year 2000, respectively. Co-citation analyses reveal that the Endophthalmitis Vitrectomy Study (EVS) conducted in 1995 provides pivotal guidance for later research. Diverse pathogenic bacteria (e.g., Coagulase-negative Staphylococci, Propionibacterium acnes, Viridians Streptococci, and Bacillus cereus) or fungi (e.g., Candida, Aspergillus, and Fusarium) contribute to varying treatment principles and clinical prognosis, which should be taken seriously. In addition, intravitreal and intracameral antibiotics are the mainstay for treating and preventing infectious endophthalmitis, respectively. Conclusion Our bibliometric analysis provides an overview of dynamic evolution and structural relationships in the research field of endophthalmitis. The displayed hotspots and developmental directions have reference values for future investigation.

[PMID: 38246424 DOI: 10.1016/j.ophtha.2024.01.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 01/09/2024] [Accepted: 01/12/2024] [Indexed: 01/23/2024] Open
Abstract
PURPOSE To evaluate risk factors for intraocular pressure (IOP) spike after cataract surgery using the IRIS® Registry (Intelligent Research in Sight). DESIGN Retrospective clinical cohort study. PARTICIPANTS Adults with IRIS Registry data who underwent stand-alone phacoemulsification from January 1, 2013, through September 30, 2019. METHODS Intraocular pressure spike was defined as postoperative IOP of > 30 mmHg and > 10 mmHg from the baseline within the first postoperative week. Odds ratios (ORs) for demographic and clinical characteristics were calculated with univariable and multivariable logistic regression analyses. MAIN OUTCOME MEASURES Incidence and OR of IOP spike. RESULTS We analyzed data from 1 191 034 eyes (patient mean age, 71.3 years; 61.2% female sex; and 24.8% with glaucoma). An IOP spike occurred in 3.7% of all eyes, 5.2% of eyes with glaucoma, and 3.2% of eyes without glaucoma (P < 0.0001). Multivariable analyses of all eyes indicated a greater risk of IOP spike with higher baseline IOP (OR, 1.57 per 3 mmHg), male sex (OR, 1.79), glaucoma (OR, 1.20), Black race (OR, 1.39 vs. Asian and 1.21 vs. Hispanic), older age (OR, 1.07 per 10 years), and complex surgery coding (OR, 1.22; all P < 0.0001). Diabetes (OR, 0.90) and aphakia after surgery (OR, 0.60) seemed to be protective against IOP spike (both P < 0.0001). Compared with glaucoma suspects, ocular hypertension (OR, 1.55), pigmentary glaucoma (OR, 1.56), and pseudoexfoliative glaucoma (OR, 1.52) showed a greater risk of IOP spike and normal-tension glaucoma (OR, 0.55), suspected primary angle closure (PAC; OR, 0.67), and PAC glaucoma (OR, 0.81) showed less risk (all P < 0.0001). Using more baseline glaucoma medications was associated with IOP spike (OR, 1.18 per medication), whereas topical β-blocker use (OR, 0.68) was protective (both P < 0.0001). CONCLUSIONS Higher baseline IOP, male sex, glaucoma, Black race, older age, and complex cataract coding were associated with early postoperative IOP spike, whereas diabetes and postoperative aphakia were protective against a spike after stand-alone phacoemulsification. Glaucomatous eyes demonstrated different risk profiles dependent on glaucoma subtype. The findings may help surgeons to stratify and mitigate the risk of IOP spike after cataract surgery.

Abstract
PURPOSE The aims of this study were to determine rates of early postkeratoplasty endophthalmitis and identify sociodemographic and medical risk factors in the Medicare population. METHODS Using a retrospective cohort design, patients aged 65 years and older undergoing penetrating keratoplasty (PK), endothelial keratoplasty (EK), and anterior lamellar keratoplasty (ALK) from 2016 to 2019 among 100% Medicare Fee-or-Service database were included. Rates of early endophthalmitis within 42 days of keratoplasty were determined using the International Classification of Diseases, 10th Revision-Clinical Modification diagnostic codes. Patient and physician characteristics were compared using x2 tests, and a multivariable logistic regression model was used to evaluate factors associated with endophthalmitis. RESULTS The overall early endophthalmitis rate after keratoplasty was 0.39% (n = 216/54,822) with a median time to diagnosis of 14 (interquartile range: 5-25) days. Rates by keratoplasty types were 1.31% for cataract surgery combined with PK, 1.13% for PK, and 0.22% for EK. On multivariable analysis, the odds of endophthalmitis were higher for PK [odds ratio (OR): 5.46, 95% confidence interval (CI), 3.98-7.49] and ALK (OR: 5.45, 95% CI, 2.59-11.49) relative to EK. Patients with a Charlson Comorbidity Index (CCI) ≥3 had higher odds of endophthalmitis (OR: 1.82; 95% CI, 1.28-2.58) relative to patients with a CCI of 0. Practices located in the Midwest (OR: 0.59, 95% CI, 0.36-0.96), West (OR 0.57; 95% CI, 0.35-0.93), and Northeast (OR: 0.59 95% CI, 0.35-0.99) had lower odds of reporting endophthalmitis when compared to the South. CONCLUSIONS Patients undergoing PK and ALK and those with a CCI ≥3 had higher odds of endophthalmitis relative to EK and patients without comorbidities, respectively. Practices in the West, Midwest, and Northeast had lower odds of endophthalmitis relative to the South.

Abstract
A 76-year-old male presented with pain, redness, and decreased vision in the left eye for 5 days. The patient had undergone combined cataract extraction and vitrectomy for a macular hole 2 weeks back. The vision had reduced to the perception of light in the left eye. Clinical examination revealed lid edema, conjunctival congestion, hazy cornea, and exudative membrane in the pupillary axis with no view of the fundus. Ultrasound examination of the left eye showed plenty of moderate reflective dot echoes. The patient was diagnosed with postoperative endophthalmitis and underwent vitrectomy with intravitreal injection of antibiotics. Growth of Hathewaya histolytica was obtained from the vitreous sample. The organism was sensitive to imipenem. Three weeks following the presentation, visual acuity had improved to counting fingers at one meter in the left eye. This is the first report of endophthalmitis due to H. histolytica. Ophthalmologists should be aware of such ocular infections due to a rare microorganism.

Abstract
INTRODUCTION Digitalization in medicine, especially the electronic documentation of patient data, is revolutionizing healthcare systems worldwide. The evaluation of real-world data collected under everyday conditions presents opportunities but also challenges. Electronic medical registries provide a means to compile extensive patient data for scientific inquiries. Oregis is the first nationwide digital registry for health services research established by the German Ophthalmological Society (DOG). Intravitreal operative medicinal injections (IVOM) are among the most frequently performed procedures in ophthalmology. Data on injection numbers and injection frequencies with anti-vascular endothelial growth factor (VEGF) are already available from other countries, whereas data at a national level are not yet available in Germany due to the lack of a nationwide register. It is known that the treatment success of anti-VEGF IVOMs depends largely on the adherence to treatment and thus on the number of injections. There are also differences in cost. In the context of this study, real-world data on the frequency and distribution of intravitreal injections in German centers from 2015 to 2021 were compiled for the first time since the introduction of oregis. The aim of this study is to collect data on the use of anti-VEGF IVOMs in Germany from oregis for the first time and to show the development of injection numbers and anti-VEGF drugs used. At the same time, the possibilities of data retrieval from oregis are demonstrated using a concrete example from daily ophthalmological practice. MATERIAL AND METHODS An automated query of records was performed for all patients who received IVOM at oregis-affiliated healthcare facilities between 2015 and 2021. The number of treated patients and the use of anti-VEGF medications, including aflibercept, bevacizumab, brolucizumab, and ranibizumab, were determined. The data were collected in a pseudonymized and anonymized manner. RESULTS At the time of data collection, 9 German ophthalmological healthcare facilities were affiliated with oregis. In total, 309,152 patients were registered during the observation period, with 8474 receiving IVOMs. Over the observation period, the number of participating centers, patients, and intravitreal injections increased. The proportional share of anti-VEGF agents among the total number of injections varied during the observation period. DISCUSSION Real-world data captured in oregis offer significant potential for enhancing healthcare provision. Oregis enables the depiction of ophthalmological care conditions in Germany and contributes to research and quality assurance. The ability to query the presented data exemplifies the multitude of inquiries through which oregis can contribute to the representation of ophthalmological care in Germany.

Abstract
AIMS To determine endophthalmitis rates and risk factors following intraocular surgeries in the Medicare population. METHODS Retrospective, cross-sectional study from 2016 to 2019 in Medicare fee-for-service and Medicare Advantage beneficiaries. 100% Medicare claims were used to identify eyes that underwent intraocular surgery. Exclusion criteria included eyes that had intraocular surgery 42 days before or after and eyes in patients with a history of endophthalmitis within 12 months. RESULTS 9 744 400 intraocular surgeries were performed among Medicare beneficiaries from 2016 to 2019. A 42-day postoperative endophthalmitis rate was 0.09%. Endophthalmitis rate by surgery type was 0.43% for corneal transplant, 0.36% for secondary intraocular lens (IOL), 0.24% for retina, 0.16% for glaucoma, 0.11% for cataract combined with other procedures and 0.08% for cataract surgeries alone. On multivariable analysis, the risk of endophthalmitis was increased for all intraocular surgery types when compared with cataract surgeries; adjusted OR (aOR) 5.30 (p<0.01) for corneal transplant, aOR 4.50 (p<0.01) for secondary IOL, aOR 3.00 (p<0.01) for retina, aOR 1.93 (p<0.01) for glaucoma, aOR 1.45 (p<0.01) for combined cataract surgeries. Increased risk of developing endophthalmitis was associated with older age (≥85 vs 65-75 years: aOR 1.36; p<0.01), male sex (aOR 1.20; p<0.001) and greater Charlson Comorbidity Index (≥7 vs 0: aOR 1.79; p<0.01). CONCLUSIONS Postoperative endophthalmitis rate after intraocular surgeries was 0.09% between 2016 and 2019 for Medicare beneficiaries. Endophthalmitis rates were highest for corneal transplant surgeries followed by secondary IOL surgeries and lowest for cataract surgeries. Older age, male gender and higher comorbidity index were associated with risk of endophthalmitis.

Abstract
Objective To describe visual acuity data representation in the American Academy of Ophthalmology Intelligent Research in Sight (IRIS) Registry and present a data-cleaning strategy. Design Reliability and validity study. Participants Patients with visual acuity records from 2018 in the IRIS Registry. Methods Visual acuity measurements and metadata were identified and characterized from 2018 IRIS Registry records. Metadata, including laterality, assessment method (distance, near, and unspecified), correction (corrected, uncorrected, and unspecified), and flags for refraction or pinhole assessment were compared between Rome (frozen April 20, 2020) and Chicago (frozen December 24, 2021) versions. We developed a data-cleaning strategy to infer patients' corrected distance visual acuity in their better-seeing eye. Main Outcome Measures Visual acuity data characteristics in the IRIS Registry. Results The IRIS Registry Chicago data set contains 168 920 049 visual acuity records among 23 001 531 unique patients and 49 968 974 unique patient visit dates in 2018. Visual acuity records were associated with refraction in 5.3% of cases, and with pinhole in 11.0%. Mean (standard deviation) of all measurements was 0.26 (0.41) logarithm of the minimum angle of resolution (logMAR), with a range of - 0.3 to 4.0 A plurality of visual acuity records were labeled corrected (corrected visual acuity [CVA], 39.1%), followed by unspecified (37.6%) and uncorrected (uncorrected visual acuity [UCVA], 23.4%). Corrected visual acuity measurements were paradoxically worse than same day UCVA 15% of the time. In aggregate, mean and median values were similar for CVA and unspecified visual acuity. Most visual acuity measurements were at distance (59.8%, vs. 32.1% unspecified and 8.2% near). Rome contained more duplicate visual acuity records than Chicago (10.8% vs. 1.4%). Near visual acuity was classified with Jaeger notation and (in Chicago only) also assigned logMAR values by Verana Health. LogMAR values for hand motion and light perception visual acuity were lower in Chicago than in Rome. The impact of data entry errors or outliers on analyses may be reduced by filtering and averaging visual acuity per eye over time. Conclusions The IRIS Registry includes similar visual acuity metadata in Rome and Chicago. Although fewer duplicate records were found in Chicago, both versions include duplicate and atypical measurements (i.e., CVA worse than UCVA on the same day). Analyses may benefit from using algorithms to filter outliers and average visual acuity measurements over time.

Abstract
Introduction: Dry eye is a common ocular condition causing discomfort and visual disturbances. Anti-inflammatory agents like Cyclosporine A (CsA) are often used in its treatment. However, the impact of CsA on ocular flora remains understudied. This research aimed to evaluate changes in conjunctival and nasal microflora in patients receiving topical cyclosporine for dry eye. Methods: In this cross-sectional study, conjunctival and nasal samples were collected from two groups of dry eye patients. Group 1 consisted of 38 patients using CsA eye drops, while Group 2 included 34 patients using preservative-free artificial tear drops. Bacterial cultures were grown from the samples, and the identified organisms underwent antibiotic susceptibility testing. Additionally, alpha diversity metrics were employed to assess the diversity of bacterial species in the samples. Results: Bacterial growth was observed in 75% of conjunctival samples and 97.22% of nasal samples. Staphylococcus epidermidis was the predominant organism in both groups. Alpha diversity analysis showed no significant differences in Shannon diversity and OTU richness between the groups for most bacterial species. Antibiotic susceptibility tests revealed no substantial variations in resistance patterns between the groups. Conclusion: This study provides valuable insights into the impact of CsA eye drops on conjunctival and nasal flora in dry eye patients. The findings suggest that CsA does not significantly influence the composition, diversity, or antibiotic resistance patterns of ocular flora. Long-term topical cyclosporine treatment for dry eye does not significantly impact conjunctival microflora or lead to antibiotic resistance. These results have important implications for the safe use of CsA in patients undergoing ocular treatments, particularly those at risk of intraocular infections.

Abstract
PURPOSE To evaluate risk factors for postoperative endophthalmitis in pediatric cataract surgery based on an analysis of a large insurance claims database. METHODS We retrospectively analyzed pediatric (0-18 years) cataract surgeries from the IBM MarketScan Research Database from 2004 to 2017. Suspect cases of endophthalmitis were identified by International Classification of Diseases codes; confirmed cases, by Current Procedural Terminology codes within 7 days of diagnosis. Odds ratios (OR) were assessed for age, sex, aphakia, concomitant vitrectomy, open-globe injury, uveitis, lens displacement, developmental delay, trisomy 21, and immunocompromised status. RESULTS Among 5,304 eyes of 6,835 patients, the following were factors significantly associated with pediatric cataract surgery-related suspect endophthalmitis: open-globe injury (OR = 7.75; 95% CI, 3.32-18.09; P < 0.001), ocular trauma (OR = 3.64; 95% CI, 1.83-7.24; P < 0.001), aphakia (OR = 2.33, CI 1.15-4.69, P = 0.018), and developmental delay (OR = 4.24, 95% CI, 1.00-18.02; P = 0.05). With univariate analysis of confirmed endophthalmitis cases, the following were identified as statistically significant: open-globe injury (OR = 8.1; 95% CI, 2.64-24.87; P < 0.001), ocular trauma (OR = 4.34, CI 1.72-10.97; P = 0.002), subluxated or dislocated lens (OR = 3.62; 95% CI, 1.04-12.57; P = 0.043), aphakia (OR = 2.86; 95% CI, 1.13-7.26; P = 0.027), and developmental delay (OR = 8.24; 95% CI, 1.86-36.44; P = 0.005). Age, sex, concomitant vitrectomy, and uveitis were not associated with increased risk of endophthalmitis. CONCLUSIONS Developmental delay may be a risk factor for postoperative endophthalmitis in pediatric cataract surgery. Surgeons can assess preoperative risk by performing a detailed medical and social history for challenges particular to this population that may complicate the postoperative course.

Abstract
Hydrogels are a type of functional polymer material with a three-dimensional network structure composed of physically or chemically cross-linked polymers. All hydrogels have two common features: first, their structure contains a large number of hydrophilic groups; therefore, they have a high water content and can swell in water. Second, they have good regulation, and the physical and chemical properties of their cross-linked network can be changed by environmental factors and deliberate modification methods. In recent years, the application of hydrogels in ophthalmology has gradually attracted attention. By selecting an appropriate composition and cross-linking mode, hydrogels can be used in different fields for various applications, such as gel eye drops, in situ gel preparation, intravitreal injection, and corneal contact lenses. This Review provides a detailed introduction to the classification of hydrogels and their applications in glaucoma, vitreous substitutes, fundus diseases, corneal contact lenses, corneal diseases, and cataract surgery.

Abstract
PURPOSE Increasing rates of antibiotic resistance in endophthalmitis have been reported. This study examines outcomes of triple therapy with intravitreal vancomycin, ceftazidime, and moxifloxacin for endophthalmitis. METHODS Retrospective, consecutive series of all patients treated with abovementioned intravitreal antibiotics from January 2009 to June 2021. Percentages of eyes attaining greater than or equal to 20/200 and 20/50 Snellen visual acuities and adverse events were evaluated. RESULTS 112 eyes met inclusion criteria. 63 of 112 eyes (56%) achieved a visual acuity of 20/200 during follow-up, with 39 (35%) returning to at least 20/50. In subgroup analysis, 23 of 24 (96%) eyes with post-cataract endophthalmitis obtained ≥ 20/200 acuity and 21 of 24 (88%) obtained ≥ 20/50 acuity during follow-up. There were no cases of macular infarction. CONCLUSIONS Intravitreal moxifloxacin (160 µg/0.1 mL) was well tolerated as an adjunct to vancomycin and ceftazidime for bacterial endophthalmitis. Use of this novel combination offers several theoretical advantages compared to standard therapy with two antibiotics, including expanded gram-negative coverage and potential synergy, and may be particularly valuable in geographies where the local antibiogram supports empiric use. Further study is merited to verify the safety and efficacy profile.

Abstract
PURPOSE To determine the incidence, risk factors, and visual outcomes of cystoid macular edema (CME) after cataract surgery in the United States. DESIGN Retrospective, longitudinal, case-control study. PARTICIPANTS Patients aged ≥ 18 years who underwent phacoemulsification cataract surgery. METHODS The American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) was used to analyze patients who underwent cataract surgery between 2016 and 2019. Patients who received a diagnosis of CME within 90 days after cataract surgery were classified as cases, and the rest were classified as controls. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for risk factors associated with the development of CME as well as poor visual outcome (defined as a best-recorded visual acuity worse than 20/40 Snellen equivalent at postoperative month 12). MAIN OUTCOME MEASURES Incidence, demographics, baseline characteristics, and visual outcomes. RESULTS Of 3.1 million cataract surgeries performed during the study period, CME was diagnosed in 25 595 eyes (0.8%), with an average onset of 6 weeks. Patients with CME were more likely to be male, to be aged < 65 years, to be Black, and to have preexisting diabetic retinopathy. Patients with CME were more likely to have a poor visual outcome (OR, 1.75; 95% CI, 1.66-1.84; P < 0.001), with a mean best-recorded visual acuity of 20/30 at postoperative month 12 (compared with 20/25 for those without CME; P < 0.001). Other factors associated with a poor visual outcome included smoking, Medicaid insurance, non-White race, and baseline ocular comorbidities such as macular degeneration and retinal vein occlusion. CONCLUSIONS Although the incidence of CME after cataract surgery is low and most eyes achieve a visual acuity of 20/40 or better, there are significant outcome disparities that warrant further exploration.

Abstract
A clear corneal incision (CCI) is the most commonly used entrance site in modern phacoemulsification cataract surgery. Despite some initial concerns about increased endophthalmitis rates through a self-sealing CCI, recent literature suggests that the risk of infection with proper wound construction and all other necessary precautions is minimal. The technique of creating a clear corneal incision has, with recent developments in corneal imaging, undergone critical appraisal leading to a better understanding of incision architecture. Many surgeons operate through smaller incisions, and they have a wide choice of surgical instruments to create their corneal incisions. The aim of this review is to discuss the history and the current status of clear corneal incision creation, the design and materials of surgical blades, and the current trends in manufacturing and sustainability. Although disposable instruments have some advantages and are very popular, recycling, if possible, and avoiding unnecessary plastic waste are important considerations. In any case, the step of CCI is a small one for the surgeon, but a big one for the eye. That is why it has to be done with the utmost precision and in-depth knowledge is important.

Abstract
PURPOSE To evaluate the rate of adverse events after office-based lens surgery performed across multiple private practices in the United States. SETTING 36 private practices across the U.S. DESIGN Retrospective multicenter study. METHODS This analysis included case records of all consecutive patients who underwent office-based lens surgery for visually significant cataract, refractive lens exchange, or phakic intraocular lens implantation between August 2020 and May 2022 at 36 participating sites across the U.S. The study outcome measures included the assessment of intraoperative and postoperative complications such as the incidence of unplanned vitrectomy, iritis, corneal edema, and endophthalmitis after lens surgery. The frequency of patients requiring a return to the operating room (OR) or referral to a retina surgeon and the frequency of patients requiring hospitalization or calling emergency services (911) for any reason were also evaluated. RESULTS The study reviewed 18 005 cases of office-based cataract or refractive lens surgery performed at 36 clinical sites. The rates of postoperative endophthalmitis, toxic anterior segment syndrome, and corneal edema were 0.028%, 0.022%, and 0.027%, respectively. Unplanned anterior vitrectomy was performed in 0.177% of patients. Although 0.067% of patients needed to return to the OR, 0.011% of patients were referred to the hospital. CONCLUSIONS The rate of adverse events for office-based cataract or refractive lens surgery is similar to or less than the reported adverse event rate for modern cataract surgery in the ambulatory surgery center setting.

Abstract
BACKGROUND The health sector is facing new challenges due to the impact of climate change on health. At the same time, it significantly contributes to our society's climate footprint. Hospitals producing considerable amounts of waste are an important aspect of this burden. The aim of this work was to quantify the amount of waste produced by eye surgery and, as an optimization measure, to evaluate the effect of glass separation from residual waste. MATERIAL AND METHODS Over a 2-week period, the waste generated by eye operations in the surgical theater of our university hospital was measured. Another 2‑week long measurement was conducted after the initiation of glass separation from general waste. The data obtained allowed a comparison of the two periods, the type of waste (residual and recyclable) as well as the type of operation (intraocular, extraocular). Considering regional waste disposal costs, an economic comparison was also performed. RESULTS In the first measurement period (196 operations), a total of 549.6 kg of waste was generated, 87% (478.3 kg) of which was residual waste, corresponding to 14.3 tons of total waste annually. Intraocular procedures generated on average 80% more waste than extraocular procedures: 18.1 ± 3.9 kg and 11.4 ± 4.0 kg, respectively, per day and theater. Separation of glass from residual waste reduced its quantity by 7.2% in the second measurement period (197 procedures). As the disposal of glass is free of charge in the city of Essen, this resulted in a small economic advantage (extrapolated to 112 € per year). CONCLUSION The amount of waste generated by ophthalmic surgery is substantial, with a predominant proportion of non-recyclable residual waste. Intraocular operations are the cause of the majority of the waste produced. Simple measures, such as disposing of glass separately, are helpful and inexpensive to reduce the quantity of residual waste.

Abstract
PURPOSE Exogenous endophthalmitis (ExE) results from microbial infection as a complication of ocular surgery, penetrating ocular trauma, and intraocular foreign bodies. We herein review the classification of ExE, etiological agents, differential diagnosis and therapeutic challenges. METHODS Narrative Literature Review. RESULTS Identification of the causative agent through ocular fluid analysis is central in the diagnostic work-up of ExE. Prompt intravitreal antimicrobial therapy is key to successful management of ExE and vitrectomy is essential in severe cases. In culture-negative cases, and in the presence of specific features, a diagnosis of sterile intraocular inflammation or toxic syndrome should be suspected. CONCLUSION Strict adherence to treatment guidelines may improve outcomes of ExE, however the ultimate prognosis, especially in severe cases, may depend more on the virulence of the causative organism and associated ocular complications. Accurate differential diagnosis and effective treatment are crucial elements in the management and prognosis of non-infectious masquerades of ExE.

Abstract
Background: Early vitrectomy for postsurgical endophthalmitis may improve visual acuity outcomes. Silicone oil as a tamponade has some potential benefits in the management of endophthalmitis. This study aims to evaluate the use of a silicone oil tamponade in the surgical management of endophthalmitis. Material and Methods: All patients with a pars plana vitrectomy with silicone oil tamponade for postsurgical endophthalmitis at the Department of Ophthalmology, University of Bonn, Germany, between 2017 and 2021 were retrospectively reviewed. We included all preoperative data, including BCVA at diagnosis, clinical findings, and symptoms. For every follow-up visit, we looked at BCVA and complications. Results: In total, 82 patients were included in this study. The mean follow-up was 13.1 months (range 1-58 months). An intravitreal injection was the cause in 42 patients (51.2%) and cataract surgery in 29 patients (35.4%). The mean interval between the causing event and the date of onset was 8.8 days (range, 1-59 days). The most prevalent pathogen was Staphylococcus epidermidis in 16 patients (19.5%). In 47 patients (57.3%), no pathogen was found. The initial best-corrected visual acuity was 2.1 logMAR and improved significantly to 1.0 logMAR after six months (p < 0.001) and 1.1 logMAR after 1 year (p < 0.001). In a multivariate analysis, a low BCVA at diagnosis (p = 0.041) was a significant predictor for poor visual acuity outcomes. A total of 17 patients (20.1%) developed postoperative complications. Five patients (6.1%) needed an anterior chamber washout with repeated injections of antibiotics. Two patients (2.4%) had persistent fibrin and were treated with YAG-laser treatment. Three patients (6.7%) developed a retinal detachment. Two patients (2.4%) had persistent corneal decompensation with endothelial cell loss and received perforating keratoplasty. We performed a matched-pair analysis (n = 30, each group n = 15) to compare a silicone oil tamponade with BSS at the end of surgery. The visual acuity outcome showed no significant differences (BCVA after one year: 1.17 logMAR in eyes with silicone oil and 0.90 logMAR in eyes with BSS; p = 0.684). Conclusions: In our study, a vitrectomy with silicone oil tamponade in the surgical management of postoperative endophthalmitis led to a significant improvement in visual acuity and had a low complication rate. Low BCVA at diagnosis was significantly associated with poor visual acuity outcomes. A comparison of silicone oil and BSS at the end of surgery showed similar results.

Abstract
OBJECTIVES To evaluate result of early pars plana vitrectomy (PPV) within 24 hours of presentation for acute postoperative endophthalmitis after cataract operation, and to determine factors that predict visual outcome. METHODS Consecutive patients who developed acute postoperative endophthalmitis within 6 weeks after cataract operation were reviewed. Patients were divided into two groups for analysis: (1) those receiving PPV within 24 hours of presentation (early PPV group), and (2) those receiving initial intravitreal antibiotics only without PPV within 24 hours of presentation (IVA group). RESULTS Out of 41,411 cataract operations, 22 eyes developed acute postoperative endophthalmitis. Presenting VA was hand-movement or worse in 72.7%. The most common organisms were Staphylococcus (40.9%), Streptococcus (13.6%) and Enterococcus (13.6%). 22.7% of eyes had good final VA ≥ 20/30 and 27.3% had poor final VA < 20/400. Early PPV group had significantly lower rate of requiring additional treatments to control infection (25% versus 80%, P = 0.030), higher rate of retinal detachment (25% versus 0%, P = 0.221) and similar final logMAR VA (1.08 ± 1.08 versus 0.80 ± 0.80, P = 0.489) compared to IVA. Multivariate linear regression analysis showed that worse final VA was significantly associated with Streptococcus (ß = 1.92, P = 0.007) and retinal detachment (ß = 1.72, P = 0.005) but not with early PPV (P = 0.225). CONCLUSION Early PPV was superior to initial intravitreal antibiotics alone as it required fewer additional treatments to control infection. Visual outcome was similar between early PPV and initial intravitreal antibiotics alone despite high number of poor presenting VA of light-perception in early PPV group. Streptococcal infection and retinal detachment were major poor prognostic factors for vision.

Abstract
The healthcare sector is a significant greenhouse gas emitter. Cataract surgery is a procedure that results in a large amount of carbon dioxide (CO2) emissions. We sought to review the literature for factors contributing to the carbon footprint of this procedure. The literature, although limited, varies greatly by region. The carbon footprint of cataract surgery ranged from approximately 6 kg CO2 equivalents in a center in India to 181.9 kg CO2 equivalents in a center in the United Kingdom. Factors contributing to the carbon footprint of cataract surgery included the procurement of materials, energy use, and the emissions associated with travel. Factors facilitating a lower carbon footprint include the reuse of surgical materials and more efficient autoclave settings. Potential areas for improvement to consider include the reduction in packaging material, the reuse of materials, and potentially reducing travel emissions by performing simultaneous bilateral cataract surgery.

Abstract
Herpes simplex virus uveitis without corneal reactivation is more frequent than previously thought. Although herpes simplex virus has been implicated as a cause of postoperative uveitis and endophthalmitis, it has not been reported as a cause of acute postoperative endophthalmitis within the early postoperative period, specifically within one week following cataract extraction. A 55-year-old man with vascularized irregular central disc-shaped stromal corneal opacity with complicated cataracts underwent cataract surgery. Intraoperatively, there was posterior capsular rent, requiring anterior vitrectomy. On postoperative day three, the patient had an increase in inflammation in the anterior chamber (grade 4+) with marked vitreous haze (grade 4). Vitreous taps were negative for bacteria and fungi, and despite intravitreal injections of vancomycin and ceftazidime, the patient had worsening of inflammation with increasing exudates and the appearance of the fibrinous membrane in the anterior chamber. Polymerase chain reaction (PCR) of aqueous and vitreous samples at this point of time yielded positive serology for herpes viral DNA, and the patient was started on oral valacyclovir. The ocular inflammation resolved soon after switching to oral valacyclovir. Typical acute postoperative endophthalmitis starts two to seven days after surgery, and the most common isolate in vitreous biopsies is coagulase-negative staphylococci. We report a rare case of acute-onset herpetic endophthalmitis presenting within 72 hours following cataract surgery for a complicated cataract in a patient with a history of pre-existing healed viral keratitis. Our case highlights that a suspicion of viral endophthalmitis should be kept in mind as a cause of acute-onset post-cataract surgery endophthalmitis, especially in cases of surgery that fail to yield a positive result on Gram's stain, culture or PCR for bacteria and fungi.

Abstract
PURPOSE OF REVIEW The aim of this study was to update visual outcomes, microbial spectrum and complications in eyes with endophthalmitis following cataract surgery. RECENT FINDINGS A single-institution, retrospective review of eyes treated for endophthalmitis following cataract surgery between 2 January 2014 and 10 January 2017. This study included 112 cases of endophthalmitis following cataract surgery, 58 of which were culture-positive (51.8%). The most isolated organisms were coagulase-negative Staphylococci (56.9%). Oral flora were present in 17.2% of cases. At 6 months, 71.7% of patients achieved visual acuity of at least 20/200 and 51.7% achieved at least 20/40 or better. Visual acuity was better in culture-negative vs. culture-positive cases (∼20/290 vs. ∼20/80, P = 0.03), and in nonoral flora-associated vs. oral flora-associated culture-positive cases (∼CF vs. ∼20/150, P < 0.01). SUMMARY Following postcataract surgery endophthalmitis, approximately 70% of eyes achieved vision of 20/200 or better and half achieved vision of 20/40 or better 6 months after treatment. Poor visual outcomes were seen in eyes with positive bacterial cultures and with oral flora.

Am J Ophthalmol 2023; 247:152-160. [PMID: 36375588 DOI: 10.1016/j.ajo.2022.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 11/04/2022] [Accepted: 11/04/2022] [Indexed: 11/13/2022]
Abstract
PURPOSE To determine the cost-effectiveness of preoperative topical antibiotic prophylaxis for the prevention of endophthalmitis following cataract surgery. DESIGN Cost-effectiveness analysis using a decision-analytic microsimulation model. METHODS Preoperative topical antibiotic prophylaxis vs no-prophylaxis costs and effects were projected over a life-time horizon for a simulated cohort of 500 000 adult patients (≥18 years old) requiring cataract surgery in theoretical surgical centers in the United States. Efficacy and cost (2021 US dollars) values were obtained from the literature and discounted at 3% per year. RESULTS Based on inputted parameters, the mean incidence of endophthalmitis following cataract surgery for preoperative topical antibiotic prophylaxis vs no-prophylaxis was 0.034% (95% CI 0%-0.2%) and 0.042% (95% CI 0%-0.3%), respectively-an absolute risk reduction of 0.008%. The mean life-time costs for cataract surgery with prophylaxis and no-prophylaxis were $2486.67 (95% CI $2193.61-$2802.44) and $2409.03 (95% CI $2129.94-$2706.69), respectively. The quality-adjusted life-years (QALYs) associated with prophylaxis and no-prophylaxis were 10.33495 (95% CI 7.81629-12.38158) and 10.33498 (95% CI 7.81284-12.38316), respectively. Assuming a cost-effectiveness criterion of ≤$50 000 per QALY gained, the threshold analyses indicated that prophylaxis would be cost-effective if the incidence of endophthalmitis after cataract surgery was greater than 5.5% or if the price of the preoperative topical antibiotic prophylaxis was less than $0.75. CONCLUSIONS General use of preoperative topical antibiotic prophylaxis is not cost-effective compared with no-prophylaxis for the prevention of endophthalmitis following cataract surgery. Preoperative topical antibiotic prophylaxis, however, would be cost-effective at a higher incidence of endophthalmitis and/or a substantially lower price for prophylaxis.

Abstract
BACKGROUND To discover whether the timing of intravitreal antibiotics, from the time of presentation to injection, affects the visual outcomes of patients with endophthalmitis from all causes. METHODS A retrospective study of consecutive patients managed at Auckland District Health Board between 1 January 2004 and 1 July 2021. The main outcome measure was final visual acuity at follow-up and the proportion of subjects with severe vision loss (≤6/60). RESULTS Three hundred and seventy-four eyes were included in the study, with a median age of 69.7 years at presentation; 192 subjects (51.6%) were female. The median presenting visual acuity was hand movements and hypopyon was present in 194 subjects (51.9%). Cataract surgery was the most frequent aetiology in 115 subjects (30.7%), followed by intravitreal anti-vascular endothelial growth factor injections in 89 subjects (23.8%) and endogenous endophthalmitis in 54 subjects (14.4%). Median time to injection of intravitreal antibiotics was 3.5 h (Interquartile range 2-6). On multivariate analysis, early treatment with intravitreal antibiotics was associated with better visual outcome, particularly for those treated within 2 h, while poor presenting visual acuity and culture-positive endophthalmitis were associated with worse outcomes. CONCLUSION Rapid intravitreal antibiotic administration is associated with better final visual acuity outcomes, particularly for those receiving treatment within 2 h of presentation. Patients with severe vision loss on presentation, benefit the most with improved final visual acuity following expedited treatment.

Abstract
Purpose To identify clinical factors associated with the need for future surgical intervention following closed globe ocular trauma. Design Retrospective cohort study. Subjects Participants and/or Controls Patients in the American Academy of Ophthalmology Intelligent Research in Sight (IRIS®) Registry with a diagnosis of closed globe ocular trauma occurring between 2013 and 2019, identified using International Classification of Disease, 10th Revision and Systematized Nomenclature of Medicine codes. Methods Diagnosis codes were used to identify multiple concomitant diagnoses present on the date of closed globe ocular trauma. Survival analyses were performed for each outcome of interest, and linear regression was used to identify clinical factors associated with the risk of surgical intervention. Main Outcome Measures Outcomes included retinal break treatment, retinal detachment (RD) repair, retinal break treatment or RD repair, glaucoma surgery, and cataract surgery. Results Of the 206 807 patients with closed globe ocular trauma, 9648 underwent surgical intervention during the follow-up period (mean, 444 days): 1697 (0.8%) had RD repair, 1658 (0.8%) had retinal break treatment, 600 (0.3%) had glaucoma surgery, and 5693 (2.8%) had cataract surgery. Traumatic cataract was the strongest risk factor for cataract surgery (hazard ratio, 13.0; 95% confidence interval, 10.8-15.6), traumatic hyphema showed highest risk for glaucoma surgery (7.24; 4.60-11.4), and vitreous hemorrhage was the strongest risk factor for retinal break treatment and detachment repair (11.01; 9.18-13.2 and 14.2; 11.5-17.6, respectively) during the first 60 days after trauma date. Vitreous hemorrhage was a risk factor for cataract surgery at > 60 days after trauma date only. Iris-angle injury was the strongest risk factor for glaucoma surgery > 60 days after trauma, while vitreous hemorrhage remained the strongest factor for retinal break treatment and detachment repair at > 60 days. Traumatic hyphema was a risk factor for all surgical outcomes during all follow-up intervals. Conclusions Diagnosis of concomitant traumatic cataract, vitreous hemorrhage, traumatic hyphema, and other risk factors may increase the likelihood of requiring surgical intervention after closed globe ocular trauma.

Abstract
94 million people are blind or visually impaired globally, and cataract is the most common cause of blindness worldwide. However, most cases of blindness are avoidable. Cataract is associated with decreased quality of life and reduced life expectancy. Most cases of cataract occur after birth and share ageing and oxidative stress as primary causes, although several non-modifiable and modifiable risk factors can accelerate cataract formation. In most patients, phacoemulsification with intraocular lens implantation is the preferred treatment and is highly cost-effective. There has been an increase in the use of comprehensive cataract surgical services, including diagnoses, treatment referrals, and rehabilitation. However, global inequity in surgical service quality is still a limitation. Implementation of preoperative risk assessment, risk reduction strategies, and new surgical technologies have made cataract surgery possible at an earlier stage of cataract severity with the expectation of good refractive outcomes. The main challenge is making the service that is currently available to some patients accessible to all by use of universal health coverage.

Abstract
The accelerated growth in electronic health records (EHR), Internet-of-Things, mHealth, telemedicine, and artificial intelligence (AI) in the recent years have significantly fuelled the interest and development in big data research. Big data refer to complex datasets that are characterized by the attributes of "5 Vs"-variety, volume, velocity, veracity, and value. Big data analytics research has so far benefitted many fields of medicine, including ophthalmology. The availability of these big data not only allow for comprehensive and timely examinations of the epidemiology, trends, characteristics, outcomes, and prognostic factors of many diseases, but also enable the development of highly accurate AI algorithms in diagnosing a wide range of medical diseases as well as discovering new patterns or associations of diseases that are previously unknown to clinicians and researchers. Within the field of ophthalmology, there is a rapidly expanding pool of large clinical registries, epidemiological studies, omics studies, and biobanks through which big data can be accessed. National corneal transplant registries, genome-wide association studies, national cataract databases, and large ophthalmology-related EHR-based registries (e.g., AAO IRIS Registry) are some of the key resources. In this review, we aim to provide a succinct overview of the availability and clinical applicability of big data in ophthalmology, particularly from the perspective of corneal diseases and cataract, the synergistic potential of big data, AI technologies, internet of things, mHealth, and wearable smart devices, and the potential barriers for realizing the clinical and research potential of big data in this field.

Abstract
PURPOSE To compare the use of single‑pass four‑throw (SFT) and traditional double-pass two-throw knotting (DTT) techniques in pupilloplasty for traumatic mydriasis combined with lens dislocation, and to evaluate the learning curve between the two knotting techniques by wet lab. METHOD The eyes of 45 patients (45 eyes) were divided into two groups according to the knotting technique used: single‑pass four‑throw (22 eyes) or traditional double-pass-two-throw knotting (23 eyes). Combined phacoemulsification and pupilloplasty with pars plana vitrectomy were performed in traumatic mydriasis patients with lens dislocation. Preoperative and postoperative corrected distance visual acuity (CDVA), pupil diameter, intraocular pressure (IOP), pupilloplasty time, and complications were compared. Twenty ophthalmology residents were randomized to perform a pupilloplasty suturing exam with or without SFT knotting techniques in porcine eyes. RESULT All cases had a minimum follow‑up period of 6 months (range 6-12 months). There was no significant difference in the CDVA (P = 0.55), postoperative pupil diameter (P = 0.79), IOP (P > 0.05), anterior chamber exudate degree, and loosening or shedding of the line knot between the two groups. The duration of the pupilloplasty was 22.32 ± 4.58 min in the SFT group and 30.35 ± 5.55 min in the traditional group, which was a significant difference (P < 0.01). The residents in the SFT group had higher test scores and fewer surgical mistakes (P < 0.05). CONCLUSION The SFT knotting technique has a similar treatment effect and safety as the traditional technique but requires a shorter time and is easier to perform in pupilloplasty surgery.

Abstract
PURPOSE The study analyzes the frequency of acute endophthalmitis occurrence after cataract surgery, the risk factors, characteristic symptoms, and the effectiveness of peri-operative prevention measures. MATERIAL AND METHODS The study retrospectively analyzed 59 670 cases of patients operated for cataract in 2017-2021. To prevent infections, patients received four instillations of third generation fluoroquinolone (quinolone antibiotic) in the course of two days prior to cataract phacoemulsification (PE), and two instillations immediately (1 hour and 30 minutes) before the surgery; three-minutes treatment of the cornea, conjunctival sac and periocular skin with 5% povidone iodine before the surgery; and as the last step of surgery, patients received subconjunctival injection of 0.05 g cefazolin with 2 mg dexamethasone. Follow-up after surgery included four injections of 0.5% levofloxacin in the course of 7-10 days, and 0.1% dexamethasone for two weeks, or fixed combination of tobramycin and dexamethasone four times per day for two weeks. The criteria for acute endophthalmitis are: loss of spatial vision, absence of red reflex, pronounced thickening of the choroid, suspended particulates in the retrovitreal space and the vitreous observed with ultrasonography in the early postoperative period (day 4-7 after surgery). RESULTS AND DISCUSSION There were 32 patients (0.054%) diagnosed with acute endophthalmitis. Posterior capsule rupture was the main complicative risk factor of endophthalmitis development (OR=11.75, p=0.026). Main diagnostic criteria of acute endophthalmitis were hypopyon (OR=22.5, p=0.001) and absence of red reflex (OR=19.59, p<0.001). The use of the fixed combination of tobramycin and dexamethasone was associated with 5.8-times higher risk of acute endophthalmitis than separate application of levofloxacin and dexamethasone (p=0.042). CONCLUSIONS Povidone iodine and third generation fluoroquinolone as a method of acute endophthalmitis prevention after cataract surgery demonstrate comparable efficacy to intracameral antibiotic injections.

Abstract
Purpose. To report a case of postoperative endophthalmitis after combined cataract extraction and iStent inject implantation. Observation. A 70-year-old male with a nuclear sclerotic cataract and primary open-angle glaucoma underwent an uneventful phacoemulsification cataract extraction with implantation of an intraocular lens and an iStent inject trabecular bypass stent. The patient was prescribed a postoperative regimen of ofloxacin 0.3% and prednisolone acetate 1%, 1 drop four times a day each. On postoperative day five, he presented to the emergency room for eye pain and had 4+ mixed cells in the anterior chamber (AC) without hypopyon or vitritis on exam. Prednisolone 1% eye drops were increased from four times a day to every two hours while awake. Overnight, he developed worsening vision and severe eye pain. The next morning, he was found to have increased AC cells, vitritis, and intraretinal hemorrhages and was diagnosed with endophthalmitis. The patient underwent a vitreous tap and intravitreal injections of vancomycin (1 mg/0.1 mL) and amikacin (0.4 mg/0.1 mL). Cultures grew Staphylococcus epidermidis. Lab work-up revealed underlying neutropenia. Visual acuity eventually recovered to 20/20. Conclusion and Importance. This report highlights a case of endophthalmitis associated with placement of the iStent inject. The infection was well-controlled after administration of intravitreal antibiotics without removal of the iStent inject, and visual acuity eventually recovered to 20/20. Surgeons should be aware of endophthalmitis risk following combined iStent inject placement, and good recovery is possible without removal of the implant.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an overview of updates in the diagnosis and management of pediatric cataracts, with an emphasis on recent discoveries in the last two years. RECENT FINDINGS Pediatric cataracts remain an infrequent but significant disease with vision threatening consequences. Although much of the management has not changed historically, more recent updates, particularly borrowed from adult cataract management, have influenced the field of cataract management in children. Even these studies emphasize that pediatric cataracts are a distinct clinical entity from adult-onset cataracts, and further research is needed to optimize the diagnosis and management of cataracts in childhood. SUMMARY This is an overview of the recent advancements in the diagnosis of management of pediatric cataracts, with advancements that originate from the adult cataract surgery field in addition to studies that challenge classical surgical techniques to make cataract surgery safer and to promote amblyopia therapy.

Abstract
PURPOSE The study comparatively evaluates the effectiveness of various approaches to acaricidal treatment in patients with chronic demodex blepharitis and meibomian gland dysfunctions. MATERIAL AND METHODS The study included 40 patients with chronic blepharitis (CB) of demodicosis etiology in conditions of meibomian gland dysfunction (MGD) and dry eye (DE). The 1st group of patients (20 people) received acaricidal treatment as part of therapeutic eyelid hygiene (TEH; 2 times a day) involving the use of «Blefarogel ochishchenie», «Blefarolosion», «Blefarogel forte» (contains sulfur and metronidazole). Acaricidal treatment in the patients of the 2nd group involved applications of a product containing metronidazole (2 times a day) without TEH. Control points: 1) at inclusion in the study; 2) after a course of therapy (45 days). Evaluation included: patient acarograms, symptoms and signs of CB (points); OSDI; tear film break-up time (TBUT, sec), severity of meibomian gland dysfunction (S-MGD, points). Statistical analysis: calculation of M±SD, Mann-Whitney, and Wilcoxon tests. RESULTS Acaricidal treatment was effective in both groups (reduction in demodex population, which was more pronounced in the 1st group). Symptoms and signs of CB were significantly less pronounced in the patients of the 1st group after therapy. The patients of the 1st group showed a significant decrease in S-MGD, OSDI and an increase in TBUT, the 2nd group - a significant decrease in OSDI and an increase in TBUT at the second control point. The positive OSDI and TBUT trends were significantly more pronounced in the 1st group. CONCLUSION Acaricidal treatment as part of TEH showed a significantly more pronounced reduction in demodex population, relief of CB symptoms and sign, OSDI decrease and TBUT increase, compared to the 2nd group. Apparently, this was associated with combined acaricidal effect and significant S-MGD decrease in the patients of the 1st group.

Abstract
PURPOSE To determine the trends in anesthesia techniques for cataract surgery over the past decade and their relationship to surgical complications. SETTING Clinics affiliated with the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). DESIGN Retrospective cross-sectional register-based study. METHODS Variables include patient demographics, visual acuity, ocular comorbidities, surgery characteristics, intraoperative complications, and postoperative complications for the study period from January 2008, to December 2018. The anesthesia methods registered in the EUREQUO and included in the study are topical, combined topical and intracameral, sub-Tenon, regional, and general anesthesia. Multivariate logistic regression models for each complication were constructed to estimate the adjusted odds ratio (OR) and 95% CIs. RESULTS Complete data were available of 1 354 036 cataract surgeries. Topical anesthesia increased significantly over time (from 30% to 76%, P < .001). Sub-Tenon and regional anesthesia decreased (from 27% and 38% to 16% and 6%, respectively, P < .001), and general and combined topical and intracameral anesthesia remained stable (around 2%). Sub-Tenon (OR, 0.80; 95% CI, 0.71-0.91, P < .001), regional (0.74; 95% CI, 0.71-0.78, P < .001), general (0.53; 95% CI, 0.50-0.56, P < .001), and intracameral anesthesia (0.76; 95% CI, 0.64-0.90, P = .001) carried a significantly decreased risk of posterior capsule rupture (PCR), with and without dropped nucleus, compared with topical anesthesia. The risk of endophthalmitis was significantly lower with regional anesthesia compared with topical anesthesia (OR, 0.60; 95% CI, 0.44-0.82, P = .001). CONCLUSIONS The use of topical anesthesia for cataract surgery increased over time. Topical anesthesia is associated with an increased risk of PCR with and without dropped nucleus, and endophthalmitis.

Abstract
PURPOSE To evaluate acute-onset postoperative endophthalmitis following cataract surgery and to compare rates between resident and attending physician-performed cohorts. SETTING Bascom Palmer Eye Institute, Miami, Florida. DESIGN Retrospective chart review. METHODS Records of patients diagnosed with endophthalmitis within 6 weeks of surgery performed by attending and resident physicians between January 1, 2015, and December 31, 2020, were reviewed. Total cataract volume was obtained from institutional records, and resident case totals were obtained from case logs. Endophthalmitis cases were obtained from billing records and confirmed with chart review. RESULTS There were 22 cases of endophthalmitis among 32 505 cases (0.068%). Endophthalmitis occurred in 6 of 6447 (0.093%) resident cases and 16 of 26 058 (0.061%) attending cases ( P = .55). The most common bacterial isolates were coagulase-negative Staphylococcus (8/22, 36.3%) and Streptococcus species (3/22, 13.6%), with negative cultures in 10 (10/22, 45.5%). Initial treatment with vitreous tap and injection of intravitreal antibiotics was performed in 21 eyes (21/22, 95.4%) and vitrectomy with intravitreal antibiotic injection in one (1/22, 4.5%). Vitrectomy was performed secondarily in 9 patients (9/22, 40.9%). Corrected distance visual acuity (CDVA) at last follow-up was ≥20/40 in 13 eyes (13/22, 59%) and ≤hand motions in 3 eyes (3/22, 13.6%). CDVA (logMAR mean ± SD) was 1.22 ± 1.16 in resident and 0.49 ± 0.79 in attending cases ( P = .11). CONCLUSIONS In the current study, acute-onset postoperative endophthalmitis developed infrequently following cataract surgery. The rates and visual outcomes of endophthalmitis were similar in resident and attending cases.

Abstract
Purpose To analyze the perspectives of practicing refractive surgeons regarding the implementation of Immediate Sequential Bilateral Cataract Surgery (ISBCS) in the United States (US) and to compare their perspectives with those of European colleagues. Setting. Online refractive surgery forum. Design A survey-based questionnaire. Methods An electronic survey was emailed to all surgeon members of the Refractive Surgery Alliance (RSA) in the US. Participants were prompted to score their impressions regarding various aspects regarding ISBCS. Responses were compared to published reports conducted among European surgeons. Results The electronic link to the survey was emailed to US-based surgeon members of the RSA, where 107 participated (44.6%). Twenty-seven (25.2%) reported that they currently perform ISBCS. Twenty-three (22.5%) of the respondents indicated they felt ISCBCS should be offered as a standard of care for routine cataract surgery. For surgeons that do not perform ISBCS, the most important factors were related to medicolegal issues and decreased reimbursement, whereas evidence of effectiveness and complications related to ISBCS were less important. Compared to practitioners abroad, 67.2% of European ophthalmic surgeons, compared to 25.2% of US surgeons, perform ISBCS (p < 0.0001). Conclusions While US refractive surgeons often perform bilateral corneal procedures, many significant barriers exist to the widespread adoption of ISBCS. Concerns reported by US surgeons mirror those reported by surgeons in Europe. The majority of the US refractive surgeons in this survey indicate that ISBCS should not be the standard of care in routine cases, with the prevailing reason being concerns about decreased physician reimbursement and potential medicolegal issues, not safety.

Abstract
This position article on reducing topical drug waste with ophthalmic surgery was written by the Ophthalmic Instrument Cleaning and Sterilization Task Force, comprising representatives of the ASCRS, American Academy of Ophthalmology, American Glaucoma Society, and Outpatient Ophthalmic Surgery Society. Drug waste significantly increases the costs and carbon footprint of ophthalmic surgery. Surgical facilities should be permitted to use topical drugs in multidose containers on multiple patients until the manufacturer's labeled date of expiration, if proper guidelines are followed. Surgical patients requiring a topical medication not used for other patients should be allowed to bring that partially used medication home for postoperative use. These recommendations are based on published evidence and clarification of policies from multiple regulatory and accrediting agencies with jurisdiction over surgical facilities. Surveys suggest that most ambulatory surgery centers and hospitals performing cataract surgery are wasting topical drugs unnecessarily.

Abstract
Advances in technology, including novel ophthalmic imaging devices and adoption of the electronic health record (EHR), have resulted in significantly increased data available for both clinical use and research in ophthalmology. While artificial intelligence (AI) algorithms have the potential to utilize these data to transform clinical care, current applications of AI in ophthalmology have focused mostly on image-based deep learning. Unstructured free-text in the EHR represents a tremendous amount of underutilized data in big data analyses and predictive AI. Natural language processing (NLP) is a type of AI involved in processing human language that can be used to develop automated algorithms using these vast quantities of available text data. The purpose of this review was to introduce ophthalmologists to NLP by (1) reviewing current applications of NLP in ophthalmology and (2) exploring potential applications of NLP. We reviewed current literature published in Pubmed and Google Scholar for articles related to NLP and ophthalmology, and used ancestor search to expand our references. Overall, we found 19 published studies of NLP in ophthalmology. The majority of these publications (16) focused on extracting specific text such as visual acuity from free-text notes for the purposes of quantitative analysis. Other applications included: domain embedding, predictive modeling, and topic modeling. Future ophthalmic applications of NLP may also focus on developing search engines for data within free-text notes, cleaning notes, automated question-answering, and translating ophthalmology notes for other specialties or for patients, especially with a growing interest in open notes. As medicine becomes more data-oriented, NLP offers increasing opportunities to augment our ability to harness free-text data and drive innovations in healthcare delivery and treatment of ophthalmic conditions.

Abstract
Adjunctive treatment of bacterial endophthalmitis with intravitreal steroids is a topic of controversy among many ophthalmologists. The objective of this study is to evaluate the effects of intravitreal dexamethasone on the visual outcomes of patients with acute bacterial endophthalmitis through a systematic review and meta-analysis. A literature search of PubMed, Scopus, and Cochrane Library databases was performed to include studies on the visual outcomes of adjuvant intravitreal dexamethasone in patients with acute bacterial endophthalmitis. The review is based on the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) protocol. A total of 1545 articles met our search criteria and after further review, two randomized controlled trials and three retrospective case series were included in the final analysis. A total of 126 eyes were treated with intravitreal dexamethasone combined with antibiotics, and another 139 eyes were treated with antibiotics alone. All cases of endophthalmitis were post-operative or post-intravitreal injection, with pooled results demonstrating no visual benefit with supplementation of intravitreal dexamethasone. Our meta-analysis does not show any visual benefit from steroid supplementation and yet, considering a relatively small number of patients included in each study, larger randomized controlled trials are required to further clarify the role of steroids in the treatment of acute bacterial endophthalmitis.
