Abstract
Importance Although the effectiveness of intracameral antibiotics to prevent postoperative endophthalmitis is described, selective use of antibiotics combined with 1% povidone iodine disinfection might be equally effective and could lead to cost reduction and avoidance of unnecessary use of antibiotics. Objective To compare the incidence of postoperative endophthalmitis when 1% povidone iodine disinfection is applied in combination with selective intracameral antibiotics with the incidence after routine use of intracameral antibiotics in combination with 5% povidone iodine. Design, Setting, and Participant This was a retrospective cohort study using incidence data from the ongoing endophthalmitis register of the Rotterdam Eye Hospital, a specialized hospital providing both secondary and tertiary ophthalmological care, when intracameral antibiotics were used only during cataract procedures with occurrence of a posterior capsular tear in comparison with results from cohorts described in the literature where routine antibiotics were used. All patients who had cataract (phacoemulsification) surgery at the Rotterdam Eye Hospital between 1993 and 2022 were included. No cataract surgical procedures combined with other intraocular procedures were included. Exposure Povidone iodine disinfection and intracameral antibiotics during cataract surgery either routinely or only in case of posterior capsular tears. Main Outcome and Measure Postoperative endophthalmitis incidence. Results Postoperative endophthalmitis incidence after 56 598 cataract (phacoemulsification) surgical procedures in the Rotterdam Eye Hospital between 2016 and 2022 was 0.000 (95% CI, 0.000-0.000). A PubMed literature search until September 2023 with respect to the incidence of postoperative endophthalmitis after routine antibiotic prophylaxis yielded 37 publications with an overall postoperative endophthalmitis incidence of 0.000 (95% CI, 0.000-0.000). Conclusions and Relevance No difference was observed between the postoperative endophthalmitis incidence during the last 7 years in the Rotterdam Eye Hospital and the overall postoperative endophthalmitis incidence after routine intracameral antibiotics prophylaxis as described in the literature. Disinfection with 1% povidone iodine in combination with selective antibiotic prophylaxis may be equally effective as routine antibiotic use and 5% povidone iodine.

Abstract
PURPOSE To study the effect of prophylactic intracameral moxifloxacin (ICM) on microbiological profile and antimicrobial sensitivity of culture-proven postoperative endophthalmitis (POE). METHODS This study evaluated culture-proven POE diagnosed within 6 weeks of cataract surgery over two periods, period-1 (January 2010-March 2015) and period-2 (April 2015-December 2019), before and after introduction of prophylactic ICM, respectively. RESULTS In period-1, 100 cases of culture-positive POE were reported (1 in 4879, 0.02%), while 20 cases (1 in 24635, 0.004%) were reported in period-2 (5-fold reduction, p < .001). The cumulative culture positivity rate decreased from 27.6% to 17.1% (1.6-fold) . Coagulase-negative Staphylococci (CoNS) were significantly reduced (p = .005). CONCLUSIONS ICM reduced the incidence of culture-proven POE, CoNS in particular. In future, POE caused by rarer pathogens may become more prevalent due to reduction in the rate of commoner and more virulent pathogens with use of intracameral antibiotics. The moxifloxacin sensitivity of CONS did not show change with the use of ICM. Studies with larger population of POE will be more helpful to understand the trend better.

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
Infectious uveitis is a major global cause of vision impairment. Despite the eye's immune privilege, afforded by the blood-ocular barrier that restricts microbial entry, several pathogens such as bacteria, viruses, fungi, and parasites can still infiltrate and cause ocular infections and complications. Clinicians often encounter significant challenges in treating infectious uveitis due to limited or ineffective treatment options. Modern molecular techniques and imaging can aid in diagnosing and assessing intraocular infections. Various antimicrobial therapies exist, spanning topical and systemic treatments, but these are constrained by issues like drug concentration, penetration, effective duration, toxicity, and side effects. Treatment approaches also differ based on the infection's etiology. This review provides recent updates on antimicrobial therapies from a clinical perspective, covering topical, systemic, and regional treatments for infectious uveitis.

Abstract
Endophthalmitis is a rare but vision-threatening infection characterized by marked inflammation of intraocular fluids and tissues, uncommonly seen following surgery and intravitreal injection. Antimicrobials are used worldwide in the prophylaxis and treatment of bacterial and fungal infections of the eye and are standard treatment in the preoperative and postoperative care of surgical patients. However, antimicrobials are reported to be overprescribed in many parts of the world, which contributes to antimicrobial resistance (AMR). AMR complicates the prophylaxis and treatment of endophthalmitis. This article examines the prevalence and mechanisms of AMR in ocular microorganisms, emphasizing the importance of understanding AMR patterns for tailored treatments. It also explores prophylaxis and management strategies for endophthalmitis, with a discussion on the use of intracameral antibiotic administration. The use of prophylactic intracameral antibiotics during cataract surgery is common in many parts of the world but is still controversial in some locations, especially in the US. Finally, it highlights the role of stewardship in ophthalmology and its benefits in the treatment of endophthalmitis.

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.

[PMID: 37227478 PMCID: PMC10587335 DOI: 10.1007/s00417-023-06095-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 04/19/2023] [Accepted: 04/26/2023] [Indexed: 05/26/2023] Open
Abstract
BACKGROUND Intracameral antibiotics, such as moxifloxacin and cefuroxime, are safe to corneal endothelial cells and effective prophylaxis of endophthalmitis after cataract surgery. Corneal endothelial cells decrease in density after cataract surgery. Any substance used in the anterior chamber may affect corneal endothelial cells and lead to a greater decrease in density. This study wants to determine the percentage of endothelial cell loss after cataract extraction by phacoemulsification with off-label intracameral injection of moxifloxacin and dexamethasone (Vigadexa®). METHODS An observational retrospective study was performed. The clinical records of patients undergoing cataract surgery by phacoemulsification plus intracameral injection of Vigadexa® were analyzed. Endothelial cell loss (ECL) was calculated using preoperative and postoperative endothelial cell density. The relation of endothelial cell loss with cataract grade using LOCS III classification, total surgery time, total ultrasound time, total longitudinal power time, total torsional amplitude time, total aspiration time, estimated fluid usage, and cumulative dissipated energy (CDE) was studied using univariate linear regression analysis and logistic regression analysis. RESULTS The median loss of corneal endothelial cells was 4.6%, interquartile range 0 to 10.4%. Nuclear color and CDE were associated with increased ECL. ECL>10% was associated with age and total ultrasound time in seconds. CONCLUSIONS The endothelial cell loss after the intracameral use of Vigadexa® at the end of cataract surgery was similar to the reported in other studies of cataract surgery without the use of intracameral prophylaxis for postoperative endophthalmitis (POE). This study confirmed the association of CDE and nuclear opalescence grade with postoperative corneal endothelial cell loss.

Abstract
Purpose To assess the current trends in use of perioperative antibiotic prophylaxis, especially intracameral antibiotics (ICAB), for cataract surgery in India. Methods This was an E-survey using a previously validated questionnaire carried out by the All India Ophthalmological Society (AIOS) in August 2022. An E-mail invitation to complete an online 40-point survey was sent to all members of the AIOS using a digital E-mail service (Survey Monkey) and social media platforms. Results Out of 1804 total respondents, 58% (n = 1022) reported using routine ICAB prophylaxis. Of those using ICAB, 89% (n = 909) reported using it for all cases, whereas the rest used it for specific indications such as post-PC rent (n = 43), one eyed patient (n = 19), and high-risk cases (n = 50). Commercially available moxifloxacin was by far the commonest agent used for ICAB (n = 686, 67%). Eighty respondents (8%) reported noticing occasional toxic reactions and nontoxic corneal edema (n = 64, 6%) with ICAB. Surgeons with >10 years' experience especially practicing in medical colleges used fewer ICAB (OR = 0.52, 95%CI = 0.38 - 0.72, P < 0,001) compared to younger surgeons (<5-year experience) in solo clinics. The commonest reason for nonadoption of IC antibiotics was "unconvinced of the need to use it in my setting" (n = 296, 52% of those who answered this question). Conclusion IC antibiotic prophylaxis for cataract surgery has significantly increased in India from 40% in 2017 to 58% in 2022. Commercially available moxifloxacin was preferred by the majority users. Intraocular inflammation may occur occasionally and needs safer formulations to avoid this.

Abstract
An intracameral (IC) injection directly delivers the drug into the anterior chamber of the eye. This targeted drug delivery technique overcomes the ocular barriers and offers a high therapeutic concentration of medication at the desired site and consequently better clinical outcomes. IC drug delivery is a safe and effective modality with many advantages over topical delivery. These include excellent bioavailability, reduced systemic risk, and minimal ocular toxicity. Agents delivered via IC injection have shown promising results against infection, inflammation, ocular hypertension, and neovascularization. Current literature shows that IC antibiotics, including cefuroxime, vancomycin, and moxifloxacin, are routinely used for prophylaxis of endophthalmitis. Other drugs available for IC use are steroids, anesthetics, mydriatics, miotics, antivascular endothelial growth factor, antiglaucoma, and alkylating agents. Introduction of sustained-release devices containing dexamethasone or Bimatoprost in anterior chamber via IC route has the potential in treating ocular inflammation and raised intraocular pressure. The complications such as hemorrhagic occlusive retinal vasculitis and toxic anterior segment syndrome have been documented with IC prophylaxis but are rare. In this review, we provide an overview of available IC drugs, their pharmacokinetics, the spectrum of activity, dosage and preparation, prophylactic and therapeutic usage, clinical efficacy, and safety profiles.

Ophthalmology 2021; 129:250-257. [PMID: 34537285 DOI: 10.1016/j.ophtha.2021.09.004] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 08/21/2021] [Accepted: 09/10/2021] [Indexed: 11/19/2022] Open
Abstract
PURPOSE To determine national incidence and risk factors associated with developing endophthalmitis after cataract surgery in the United States. DESIGN Retrospective, cross-sectional analysis. PARTICIPANTS Medicare beneficiaries aged ≥65 years undergoing cataract surgery between 2011 and 2019. METHODS Medicare claims were used to identify all patients who underwent ≥1 cataract surgery between 2011 and 2019. Endophthalmitis cases within 90 days of the cataract surgery were identified using diagnostic codes. Patients with a history of endophthalmitis 12 months before their cataract surgery procedure were excluded. Annual and aggregate 9-year incidences were determined for all cataract surgeries and for stand-alone cataract procedures. A stepwise multivariable logistic regression model using generalized estimating equations was used to evaluate factors associated with occurrence of postoperative endophthalmitis. MAIN OUTCOME MEASURES The 90-day postoperative endophthalmitis rate and patient risk factors associated with onset of endophthalmitis after cataract surgery. RESULTS A total of 14 396 438 cataract surgeries were performed among Medicare beneficiaries between 2011 and 2019. The overall 90-day postoperative endophthalmitis rate was 1.36 per 1000 cataract surgeries for all cataract procedures and 1.30 per 1000 cataract surgeries for stand-alone cataract procedures. A decreasing trend was noted for postoperative endophthalmitis rates during the 9-year study period. On multivariable analysis, the risk of endophthalmitis after cataract surgery was increased for cases performed among those aged ≥75 years versus those aged <75 years (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.11-1.18), Blacks (OR, 1.13; 95% CI, 1.07-1.20), Native Americans (OR, 1.43; 95% CI, 1.19-1.73), and eyes with any history of invasive glaucoma surgery (OR, 1.40; 95% CI, 1.18-1.65). Cataract cases combined with retinal surgery (OR, 2.60; 95% CI, 2.15-3.16) and those performed when the Charlson Comorbidity Index (CCI) was greater than 0 also had an increased likelihood of developing endophthalmitis. The risk of endophthalmitis was lower for cases performed on women versus men (OR, 0.89; 95% CI, 0.86-0.92). CONCLUSIONS The overall 90-day postoperative endophthalmitis rate after cataract surgery was 1.36 per 1000 cataract surgeries between 2011 and 2019. Patient age, gender, race, and CCI were associated with risk of endophthalmitis.

Abstract
PURPOSE This study was undertaken to evaluate the complication rates and visual outcomes of outreach cataract surgeries done in makeshift operating rooms. METHOD In this retrospective study, surgical outcomes of consecutive Manual Small Incision Cataract Surgeries (MSICS) done in 11 rural camps in Nepal were compared with the results of consecutive hospital surgeries (MSICS and phacoemulsification) done by the same surgeon. Surgeries were done from September 2018 to March 2020. RESULTS Out of 1034 study population in each group, a significantly higher number (p < .001) of camp patients (27%, n = 279) were either blind or had severe visual impairment when compared to hospital patients (18.6%, n = 192). Around 88.9% (n = 919) of cases operated in camps and 85.7% (n = 886) in the hospital achieved uncorrected visual acuity (VA) of 6/18 or better on the first postoperative day. Poor outcome (VA<6/60) was seen in 3.7% (n = 38) of cases in camps and 3.9% (n = 40) in the hospital. The difference in visual outcomes was not significant (p = .162) when the results were controlled for other associated variables. There was no significant difference (p = .126) between complication rates in camps (1.9%, n = 20) and hospital surgeries (3.5%, n = 36) when preoperative conditions were statistically controlled. No cases of endophthalmitis were reported. CONCLUSIONS Makeshift operating rooms can be used for cataract surgeries in rural areas where no standard operating rooms are available. If appropriate patient selection criteria and standard surgical protocols are followed, good surgical outcomes can be achieved in camps by an experienced surgical team.

Abstract
Postoperative endophthalmitis after cataract surgery is typically caused by the patient's own conjunctival normal bacterial flora. A three-step approach is recommended to prevent endophthalmitis: (1) "border control" to prevent microorganisms from entering the eye by disinfecting the ocular surface is the most important measure; (2) bacteria that have gained access into the anterior chamber are reduced by irrigation; (3) bacteria remaining in the anterior chamber and vitreous at the end of surgery are controlled by antibacterial drugs. We have devised a method, "the Shimada technique", for irrigating the ocular surface with povidone-iodine, a disinfectant with potent microbicidal effect and established effective and safe concentrations for eye tissues. Povidone-iodine exhibits a bactericidal effect for a wide concentration range of 0.005-10%, but 0.1% povidone-iodine has the highest activity and requires the shortest time of only 15 s to achieve microbicidal effect. When used to irrigate the ocular surface every 20-30 s during cataract surgery, 0.25% povidone-iodine is conceivably diluted to around 0.1%. Irrigation with 0.25% povidone-iodine during cataract surgery significantly reduced bacteria contamination rate in the anterior chamber compared with saline (p = 0.0017) without causing corneal endothelial damage.

Abstract
PURPOSE To report the incidence, risk factors, and visual outcomes of acute postoperative endophthalmitis in patients undergoing resurgery after cataract surgery. SETTING Tertiary eye hospital in southern India. DESIGN Retrospective, clinical registry. METHODS Medical records of patients were retrospectively reviewed from January 2010 to December 2018. Incidence, risk factors, causative organisms, management, and outcomes were studied. Patients who underwent resurgery within 6 weeks of primary cataract surgery and developed endophthalmitis within 6 weeks of resurgery were included. RESULTS A total of 5705 patients (0.64%) underwent resurgery. Of 5705 resurgeries, 11 patients (0.19%) developed postoperative endophthalmitis. The incidence of endophthalmitis was higher in the eyes having a breach in the posterior capsule than the eyes with no breach in the posterior capsule (10/1277 [0.78%] vs 1/4428 [0.02%]). Among the 11 patients, secondary intraocular lens (IOL) implantation was the most common indication for resurgery (9/11 [82%]) after which endophthalmitis occurred. Three (27.3%) of the 11 patients were culture-positive. Nine (82%) of 11 patients were managed with a vitreous tap along with intravitreal antibiotics and steroid injections. After treatment, 80% of the patients achieved a visual acuity of 6/18 or greater (logMAR 0.5, P value < .05). None of the eyes developed phthisis bulbi. CONCLUSIONS Eyes having a breach in the posterior capsule requiring vitrectomy and taken for resurgery as secondary IOL implantation were having an increased risk for endophthalmitis. The posttreatment visual outcomes were favorable.

Abstract
Objective This study was conducted to understand the effects of intracameral moxifloxacin in decreasing the incidence of postoperative endophthalmitis after cataract surgery in an eye hospital with a high volume surgical load. Methods and analysis In this single-centre, retrospective, clinical registry-based study, we compared the rates of postoperative endophthalmitis in 31 340 cataract surgery patients operated during 22 months after June 2018 who received intracameral moxifloxacin to 80 643 patients operated during 41 months before June 2018 who did not receive intracameral moxifloxacin. All patients received subconjunctival gentamycin and dexamethasone. Combined surgical procedures were excluded from the study. Results There was a significant reduction (p<0.001) of postoperative endophthalmitis rates in cataract surgeries from 0.144% (116/80 643) to 0.025% (8/31 340) after initiation of intracameral moxifloxacin. Endophthalmitis rates decreased from 0.120% (12/9942) to 0.009% (1/10 787) in phacoemulsification group and from 0.147% (104/70 701) to 0.034% (7/20 553) in manual small-incision cataract surgeries. Gram-positive organisms including Coagulase-negative staphylococci (37.9%, n=11) and Staphylococcus aureus (S. aureus 34.5%, n=10) were the most common organisms isolated out of 29 culture-positive cases. 24.1% (28/116) endophthalmitis cases in group without moxifloxacin were culture positive compared with 14.3% (1/7) of cases in moxifloxacin group. 72% (n=8) of the Coagulase-negative staphylococci and 80% of S. aureus isolates (n=8) showed in vitro sensitivity to moxifloxacin. Conclusion Prophylactic use of intracameral moxifloxacin injection in addition to subconjunctival gentamycin in cataract surgery is associated with a significant decrease in rates of postoperative endophthalmitis when compared with the use of subconjunctival gentamycin alone in high volume settings.

Abstract
Purpose The aim of this study was to evaluate the efficacy and safety of intravitreal moxifloxacin injections in the treatment of acute post-cataract surgery endophthalmitis with visual acuity equal to or greater than hand movements. Methods Fifty two patients with post-cataract surgery endophthalmitis who presented within 6 weeks with visual acuity equal to or greater than hand movements received two intravitreal moxifloxacin injections 48 h apart. Patients with prior history of ocular disease or treatment were excluded. Patients were followed up to 3 months either for resolution of endophthalmitis or worsening of disease. Number of patients who achieved visual acuity equal to or better than 20/40 and 20/200 at the third-month follow-up visit were compared with the number of patients at presentation, using Chi-square test. In addition, pretreatment LogMAR visual acuity at the time of presentation was compared with posttreatment visual acuity at end of third month using paired t test. Results Fifty (96.15%) patients showed complete resolution of endophthalmitis while three patients required vitrectomy. Forty-one (78.85%) and 49 (94.23%) patients achieved visual acuity equal to or better than 20/40 and 20/200, respectively, at the third-month follow-up visit as compared to eight (15.38%) and 13 (25%) patients, respectively, at presentation (P < 0.05). In addition, mean LogMAR visual acuity at the time of presentation was 0.755 which improved to 0.307 at the third-month follow-up visit (P < 0.05). None of the patients developed hypersensitivity reactions to intravitreal moxifloxacin. Conclusion Intravitreal moxifloxacin injections showed promising results in acute post-cataract surgery endophthalmitis.

Abstract
Immediately sequential bilateral cataract surgery (ISBCS) involves performing phacoemulsification with intraocular lens implantation in both the eyes of a patient, sequentially in the same operative sitting. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. As a result of the COVID-19 pandemic, all elective surgeries were stopped. This has resulted in a large backlog of deferred cataract surgeries. Now more than ever before, we should consider ISBCS as an excellent alternative to delayed sequential bilateral cataract surgery in the right hospital or surgical setting. In the age of COVID-19, it can help to decrease surgical scheduling and follow-up visits. The one change in practice that could have the most significant benefit in reducing infection exposure risk is ISBCS.

Abstract
PURPOSE To study the impact of prophylactic intracameral (IC) moxifloxacin on the incidence, clinical profile and outcomes in eyes developing post-cataract surgery endophthalmitis (PCE). METHODS This was a single-centre, retrospective, comparative, observational study in which all eyes with PCE between June 2013 and May 2014 without IC moxifloxacin prophylaxis (group A) and June 2015-May 2016 with IC moxifloxacin prophylaxis (group B) were analysed. RESULTS A total of 101,815 cataract surgeries were performed in group A and 112,967 in group B. PCE was diagnosed in 179 eyes (0.18%) in group A and 92 eyes (0.08%) in group B (p < 0.001). Greater reduction in risk of PCE was seen in subsidised patients compared to private. The presenting and final visual acuity was significantly better in group B (p < 0.05). CONCLUSIONS Prophylactic IC moxifloxacin reduced the incidence of PCE with maximum benefit being observed for the subsidised patients and also helped achieve a significantly better visual acuity following the resolution of endophthalmitis.

Abstract
Moxifloxacin hydrochloride (MXF) is widely used for the prevention of bacterial endophthalmitis after intraocular surgeries. However, the safety issue of intracameral injection of MXF for human corneal endothelial cells (HCECs) is still debatable. In this study, we investigated concentration-dependent cytotoxicity (0.05–1 mg/ml) of MXF for immortalized HCECs (B4G12 cell) and the underlying mechanism. Reactive oxygen generation (ROS) and cell viability after MXF exposure was measured. Flow cytometric analysis and TUNEL assay was used to detect apoptotic HCECs after MXF exposure. Ultrastructure of damaged HCECs by MXF was imaged by transmission electron microscope. Western blot analysis and caspase 2, 3 and 8 analysis were used to reveal the underlying mechanism of MXF induced damage in HCECs. We found that MXF induced dose-dependent cytotoxicity in HCECs. MXF exposure increased ROS generation and induced autophagy in HCECs. Increased LDH release represented the cellular membrane damage by MXF. In addition, caspases activation, Bax/Bcl-xL-dependent apoptosis pathway and apoptosis inducing factor nuclear translocation were all involved in MXF induced HCECs’ damage, especially after exposure to high dose of MXF (0.5 and 1.0 mg/ml). These findings suggest that MXF toxicity on HCECs should be thoroughly considered by ophthalmologists when intracameral injection of MXF is planned.

Abstract
BACKGROUND Manual small incision cataract surgery (MSICS) is a widely used technique for cataract surgery in the developing world. Higher rates of postoperative endophthalmitis have been reported with this technique compared with phaco-emulsification. The purpose of this study was to evaluate the efficacy of prophylactic intracameral (IC) antibiotics in reducing the rates of postoperative endophthalmitis following MSICS. METHODS Systematic review and meta-analysis of patients undergoing MSICS. A literature search in PubMed and EMBASE databases was performed to identify studies published from October 1992 to April 2020 evaluating MSICS with a minimum of 500 eyes reported. Two authors independently assessed eligibility, extracted data and assessed the risk of bias. Heterogeneity was assessed using the I2 test. RESULTS Twelve studies enrolling 1 494 307 eyes were included. IC antibiotics were used in 725 324 (48.5%) eyes. The risk ratio of developing endophthalmitis was 2.94 (95% CI, 1.07-8.12; P = .037) in eyes that did not receive IC antibiotics. CONCLUSIONS Routine use of IC antibiotics may help to reduce the rates of endophthalmitis following MSICS and significantly improve the safety of this effective form of cataract surgery.

Abstract
PURPOSE OF REVIEW Advances in pharmacology offer freedom from topical medical therapy without compromise of anti-inflammatory and antimicrobial coverage in the perioperative period. In this review, we describe the basis for dropless cataract surgery with the goal of improving outcomes and the patient experience. RECENT FINDINGS Phacoemulsification outcomes depend largely on surgeon skill but also on adherence to a complex multidrug regimen of perioperative anti-inflammatory and antimicrobial therapy to prevent sight-threatening complications such as cystoid macular edema or endophthalmitis. Successful administration of this regimen can be limited by noncompliance, difficulty administering eye drops, bioavailability, and side effects, among others. The recent development of sustained-release formulations of dexamethasone - one an intracanalicular insert and the other an intraocular suspension - can provide sustained tapering doses of dexamethasone while reducing or eliminating the need for anti-inflammatory eye drop therapy. Similarly, mounting evidence compellingly demonstrates that intracameral antibiotic use intraoperatively is at least as effective as topical antibiotics in preventing endophthalmitis. SUMMARY Sustained-release dexamethasone coupled with intracameral antibiotics at the time of phacoemulsification can provide antimicrobial and anti-inflammatory prophylaxis without the need for topical eye drop medications. This approach has the potential to improve compliance with therapy, visual acuity outcomes, and the overall patient experience.

Abstract
AIM To report the clinical profile, outcomes of early vitrectomy for cluster endophthalmitis developing after intravitreal Bevacizumab (IVB), and discuss the role of prophylactic intracameral moxifloxacin for eyes undergoing combined cataract surgery with IVB. METHODS Single center, retrospective analysis of 35 consecutive eyes developing post-IVB inflammation. RESULTS Of the 35 eyes that were administered IVB (27 eyes 'IVB alone' and 8 eyes 'IVB with cataract surgery'). Endophthalmitis developed in 28 eyes, 6 eyes were managed with Intravitreal antibiotic (IVAB) alone, while 22 eyes required early vitrectomy. Only one eye undergoing a combined phacoemulsification with IVB developed endophthalmitis. Majority(26/28) of the eyes achieved visual acuity equal to/greater than pre-IVB injection vision over a period of 3.15 ± 3.2 months. CONCLUSION Early detection and prompt PPV were effectual for achieving good functional outcomes in our cluster of post-IVB Klebsiella endophthalmitis. Intracameral moxifloxacin was protective in cases undergoing combined cataract surgery with IVB.

Abstract
PURPOSE To analyze the effectiveness of intracameral moxifloxacin prophylaxis in reducing acute postoperative endophthalmitis after trabeculectomy and combined trabeculectomy plus cataract extraction. DESIGN Retrospective clinical registry analysis. PARTICIPANTS Patients undergoing either trabeculectomy or trabeculectomy plus cataract extraction at Aravind Eye Hospitals (AEH) between 2009 and 2018 (inclusive). METHODS Electronic health records data were analyzed before and after implementation of routine intracameral moxifloxacin, and acute postoperative endophthalmitis rates were compared. During 2015, routine intracameral moxifloxacin prophylaxis was added in a step-wise fashion throughout AEH. Date of implementation was used to create group 1 (without intracameral moxifloxacin prophylaxis) and group 2 (with intracameral moxifloxacin prophylaxis). MAIN OUTCOME MEASURES The primary outcome was the difference in acute (≤6 weeks) postoperative endophthalmitis between groups 1 and 2. Review of culture results, visual acuity, and intraocular pressure also was performed for patients with endophthalmitis. RESULTS Thirty-eight thousand nine hundred eyes (group 1) did not receive intracameral moxifloxacin, whereas 19 086 eyes (group 2) did. Although the rate of noninfectious postoperative complications was not significantly different (0.81% vs. 0.67%; P = 0.07), a significantly lower rate of acute postoperative endophthalmitis was found in group 2 versus group 1 (0.03% vs. 0.08%; P = 0.03). Patients receiving intracameral moxifloxacin showed approximately 2.5-times lower odds of infection (odds ratio, 0.39 for group 2 vs. group 1; 95% confidence interval, 0.16-0.95) and almost 4-times lower odds after adjustment for covariates (odds ratio, 0.26 for group 2 vs. group 1; 95% confidence interval, 0.09-0.74). The rate of early postoperative infection after intracameral moxifloxacin introduction was lower for patients undergoing both trabeculectomy alone (0.09%-0.03%; P = 0.27) and combined trabeculectomy plus cataract extraction (0.08%-0.03%; P = 0.06). Although most cultures yielded no growth, no Staphylococcus or gram-negative growth was found for patients in group 2, who received intracameral moxifloxacin. CONCLUSIONS Intracameral moxifloxacin prophylaxis was associated with a nearly 4-fold lower rate of early postoperative endophthalmitis in patients undergoing trabeculectomy or combined trabeculectomy plus cataract extraction.

Abstract
PURPOSE To survey the routine application of consumables and sterilized accessories of phacoemulsification in mainland China. METHODS This was a cross-sectional questionnaire-based study. A questionnaire link was sent to Chinese ophthalmologists via the most widely used social communication tool (WeChat platform). RESULTS A total of 815 questionnaires were determined to be valid and were included in the final analysis. The majority of respondents were from Guangdong, Shandong, Zhejiang, Hebei, and Henan provinces. A number of hospitals (48.22%) reused the fluidics management system (FMS) after sterilization. Among the hospitals using disposable FMS, 38.03% reused tubing after sterilization. Most respondents' hospitals (70.43%) sterilized the handpiece for each operation. Only 38.77% of the respondents' hospitals adopted irrigation fluid antibiotics and/or intracameral antibiotics intraoperatively. Greater single usage of FMS was significantly associated with higher provincial gross domestic product (GDP), government hospitals, provincial hospitals, and disposable tubing (P < 0.05). The adoption of irrigation fluid/intracameral antibiotics was correlated with the financial type of the hospital, the daily volume of phacoemulsification, and the usage of silicone tubing (P < 0.05). CONCLUSIONS The results show a wide variation in the application of consumables and the sterilization of accessories in phacoemulsification in mainland China. Only half of the hospitals adopted interfusion/intracameral antibiotic prophylaxis, despite its efficacy having been confirmed. These data revealed potential safety issues of the sterilization of phacoemulsification instruments and the risk of intraocular infection.

Abstract
Purpose To compare short-term non-infectious clinical outcomes after cataract surgery with an intraoperative pars plana intravitreal antibiotic-steroid (IVAS) injection of triamcinolone, moxifloxacin, and vancomycin (TMV) versus a standard postoperative topical regimen. Patients and Methods A retrospective comparative case series of 1058 eyes (control = 487, treatment = 571) undergoing cataract surgery were included. Endpoints included best-corrected visual acuity (BCVA), intraocular pressure (IOP), and the unplanned use of anti-inflammatory topical medication in the postoperative period. The follow-up period ranged from 1 to 6 months. Results A final monocular BCVA of 20/25 or better was achieved in 78.8% and 87.4% of eyes in the control and treatment groups, respectively (p = 0.001). The overall incidence of an IOP spike (Δ ≥ 10 mm Hg) was not significantly different between the two groups (0.4% versus 1.9%, p = 0.027). The rates of persistent anterior chamber inflammation (PACI), rebound anterior chamber inflammation (RACI), and cystoid macular edema (CME) in the control and treatment groups were 8.0% vs 2.6% (p < 0.001), 6.4% vs 2.6% (p = 0.003), and 3.9% vs 4.7% (p = 0.511), respectively. The use of an IVAS injection of TMV conferred an increased risk of CME (odds ratio [OR] = 3.21, 95% confidence interval [CI] = 1.42 to 7.23) but no significant effect on the risk of PACI (OR = 0.34, 95% CI = 0.10 to 1.14) or RACI (OR = 0.52, 95% CI = 0.18 to 1.54) when compared to a topical regimen. Conclusion An intraoperative IVAS injection after uncomplicated cataract surgery may be as safe and effective as a standard topical regimen in terms of postoperative IOP and anterior chamber inflammatory events, respectively. However, the efficacy of a TMV formulation for CME prophylaxis appears to be unsatisfactory. Future studies with prospective and randomized designs are needed to further evaluate this technique.

Abstract
Endophthalmitis is a serious complication of cataract surgery that occurs in thousands of patients each year. To decrease the incidence of postoperative endophthalmitis, many surgeons inject intracameral antibiotics (cefuroxime, moxifloxacin, and vancomycin) routinely at the end of surgery. A large number of recently published retrospective studies and large database analyses have reported decreased endophthalmitis rates with routine antibiotic use, and the only prospective, multicenter, randomized trial performed by the European Society of Cataract and Refractive Surgery demonstrated that intracameral cefuroxime decreases the incidence of postoperative endophthalmitis. Routine cefuroxime use has become common in many European countries, whereas moxifloxacin is the most commonly used drug in India, and vancomycin use predominates in Australia. The decision regarding whether or not to use intracameral prophylaxis and the drug that is selected varies considerably throughout the world because of antibiotic availability and cost, and the spectrum of causative organisms. Adverse events due to intracameral antibiotics are infrequent, but complications such as hemorrhagic occlusive retinal vasculitis have been reported. Because additional prospective, comparative trials have not been performed, a consensus regarding best practices to prevent postoperative endophthalmitis has not been reached. Additionally, many surgeons do not routinely use intracameral antibiotics because they believe them unnecessary with modern aseptic techniques, small incision surgery, and shorter operating times. We discuss the most commonly used intracameral antibiotics, present the risks and potential benefits of this approach, and highlight challenges with drug compounding and safety.

Abstract
Introduction. Nocardia spp. can cause several ocular infections, such as keratitis, endophthalmitis and scleral abscesses. Molecular identification of Nocardia spp. by 16S rDNA sequencing is the gold standard method at present for species identification, but closely related species can only be identified by multilocus sequence analysis (MLSA) of housekeeping genes.Aim. The major objective was to profile Nocardia species, antibiotic susceptibility patterns and clinical outcomes in endophthalmitis patients.Methodology. Between January 2009 and December 2018, endophthalmitis patients who were diagnosed with Nocardia infection based on microscopic and culture characteristics were selected. Antibacterial susceptibility tests were performed and Nocardia speciation was performed using MLSA and phylogenetic tree analysis of the 16 s rRNA gene and the gyrB, hsp65 and secA1 genes.Results. A total of 43 culture-proven patients were identified during the study period. All isolates were 100 % sensitive to amikacin and 98 % resistant to ceftazidime. Fluoroquinolone sensitivity was observed in the range of 58 to 72 %. Year-wise analysis of antibiotic resistance patterns revealed there was a significant increase in resistance to fluoroquinolones. Twenty-two isolates were stored and six different species were identified. Nocardia farcinica (n=10) was found to be the most predominant, followed by Nocardia cyriacigeorgica (n=4), Nocardia otitidiscaviarum (n=3), Nocardia amikacinitolerans (n=2), Nocardia puris (n=2) and Nocardia higoensis (n=1).Conclusions. N. farcinica is the major pathogen, and this is the first report to identify N. otitidiscaviarum, N. amikacinitolerans and N. higoensis as causing endophthalmitis. Overall, visual outcomes were mostly poor even after aggressive management.

Abstract
PURPOSE To compare the rate of endophthalmitis of intracameral versus topical antibiotic prophylaxis for patients undergoing phacoemulsification at a single-centered, multispecialty ophthalmological institute. METHODS A retrospective analysis of the rate of endophthalmitis by coding search within 90 days of cataract surgery in periods before (May 15, 2012-May 15, 2014) and after (April 30, 2015-April 30, 2017) intracameral antibiotics became the institution's preferred practice pattern for phacoemulsification. Clinical data were collected for each endophthalmitis case, including timing of onset, presenting symptoms and signs, culture results, treatment performed, and visual acuity outcome. RESULTS The rate of postphacoemulsification endophthalmitis decreased from 0.18% (29 eyes among 16,201 cataract surgeries) to 0.07% (11 eyes among 16,325 surgeries) when the preferred method was changed from topical to intracameral antibiotics (P=0.004) with an odds ratio of 0.32. Endophthalmitis cases in the 2 groups had comparable visual acuity at initial presentation and at 3 months (P=0.86). The most commonly isolated organism in culture-proven cases of endophthalmitis in both groups was coagulase-negative staphylococcus. The rate of gram-positive endophthalmitis decreased from 0.08% to 0.02% with an odds ratio of 0.23 (P=0.012) while the rate of gram-negative cases remained similar. CONCLUSIONS The use of intracameral antibiotics during cataract surgery was associated with a statistically significant reduction of postoperative endophthalmitis.

Abstract
PURPOSE To analyze the outcomes of cataract surgery with emphasis on the relationship between surgery-related factors and the incidence of postoperative infectious endophthalmitis. SETTING Ninety-three surgical sites in Japan. DESIGN Prospective case series. METHODS Eyes that were scheduled to have cataract surgery from January 20 to September 30, 2014, were included. Phacoemulsification and implantation of a single-piece hydrophobic acrylic foldable intraocular lens (IOL) were performed. Patients were followed for 2 months. RESULTS Of the 9720 eyes enrolled, 9100 (93.6%) completed a 2-month follow-up. Three cases (0.033%) developed infectious endophthalmitis (95% confidence interval [CI], 0.000-0.070). The incidence of endophthalmitis was significantly associated with the removal method of ophthalmic viscosurgical devices (OVDs) after IOL implantation. The incidences of endophthalmitis in cases with and without the behind-the-lens technique were 0% (0/6147; 95% CI, 0%) and 0.084% (3/3570; 95% CI, 0.000-0.179), respectively, with a significant difference between them (P = .050, Fisher exact test). The incidence of infectious endophthalmitis did not correlate with any other patient-related and surgery-related factors. CONCLUSION The behind-the-lens technique to wash and clear the capsular bag for OVD removal significantly reduced the incidence of infectious endophthalmitis.

Abstract
PURPOSE To test the effect of injection volume and concentration on dosing and residence time of moxifloxacin in the anterior chamber (AC). SETTING Kaiser Permanente, Walnut Creek, California, USA. DESIGN Experimental study. METHODS Moxifloxacin 0.5%/0.05 mL, moxifloxacin 0.5%/0.10 mL, and moxifloxacin 0.15%/0.50 mL were drawn into 5 1.0 mL syringes each, injected into tared vials, and weighed. The doses delivered were calculated. The AC concentrations and elimination rates of the drug for two AC volumes were modeled for each dosing method. RESULTS The 0.05 mL injection volume resulted in the greatest range (35 μg) of delivered dose compared with larger injection volumes (≤25 μg). The mathematical model predicted that variation in dosing in each group would result in differences of 12 minutes or less for the presence of the drug in the AC. Injection of 0.5%/0.1 mL produced AC concentrations above 500 μg/mL for 1.9 to 3.0 hours and above 64 μg/mL for 5.5 to 6.5 hours, depending on the AC volume; however, flushing with a 0.15% concentration sustained AC levels for 1.9 hours and 5.5 hours, respectively, for the two AC volumes. CONCLUSIONS Smaller injection volumes of a higher concentration moxifloxacin resulted in less accuracy and less precision in the delivered dose (0.05 mL, P = .005; 0.10 mL, P = .03); however, the clinical significance of this might vary. Injection of 0.5%/0.1 mL and flushing with 0.15%/0.5 mL of moxifloxacin would provide similar drug AC residence times according to the model. Flushing provided more consistent AC concentrations with differing AC volumes.

Abstract
Purpose: To report a series of central retinal artery occlusions (CRAO) following cataract surgery complicated by posterior capsular rupture (PCR). Methods: Data from 14 patients with acute CRAO following cataract surgery was collected for this study including subject demographics, initial and final best-corrected visual acuity, systemic investigations, optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) findings. Results: Mean subject age was 59.9 ± 12.1 years. Male: Female ratio was 1:1. All patients were operated between October and November 2015 and presented with acute vision loss 1 to 4 days after surgery. All the patients underwent cataract surgery under peribulbar anesthesia and had PCR for which anterior vitrectomy (AV) was done. In all the cases Ethylene oxide (ETO) sterilized vitrectomy probe was used for AV. Clinical picture of CRAO was noted in all the cases during the immediate postoperative period. OCT showed inner retinal layer hyperreflectivity while FFA was normal in all the cases. The final visual acuity was poor in all the eyes. This paper discusses the possible mechanisms of CRAO in these cases. Conclusion: CRAO is a potential complication of peribulbar anesthesia for intraocular surgery in patients with vascular risk factors and hence any substance that can aggravate the vasospasm in such patients should be used cautiously. Vasospasm could be caused by ETO as residual ETO could be present in the vitrectomy machine tubing causing toxicity. It is recommended to be cautious while using ETO sterilized instruments for cataract surgery.

Abstract
Background: The assessment of the incidence and characteristic of acute and chronic postoperative endophthalmitis (POE) after cataract surgery in Poland during 2010–2015. Patients and methods: All hospitalizations of patients, in the National Database of Hospitalizations, who underwent cataract surgery alone or in combined procedures in Poland between January 2010 and December 2015, with a billing code of endophthalmitis, were selected. Acute endophthalmitis was identified if symptoms occurred within 1–42 days from the cataract surgery and chronic endophthalmitis if symptoms occurred ≥43 days after cataract surgery, respectively. Results: In total, 1331 cases of POE after 1,218,777 cataract extractions were identified. The overall incidence of POE decreased from 0.125% in 2010 to 0.066% in 2015. In multiple logistic regression analyses, increasing age was significantly associated with acute POE, while type II diabetes mellitus, extracapsular cataract extraction, and one-day surgery were significantly associated with chronic POE. The combined cataract surgery and male sex were significant risk factors for both acute and chronic POE. A total of 62.51% of all eyes affected by POE received antibiotic treatment and 37.49% had vitrectomy treatment. Conclusions: During the study period, the total incidence of postoperative endophthalmitis after cataract surgery decreased significantly.

Abstract
INTRODUCTION A case of endophthalmitis after dropless cataract surgery with intravitreal Tri-Moxi associated with severe vision loss. CASE SUMMARY An 82-year-old male developed severe vision loss in the left eye 24 days after dropless cataract surgery with intravitreal Tri-Moxi injection. Best corrected visual acuity was hand motion in the left eye. Intraocular pressure was 13, with inferior keratic precipitates, 4 + cell with 1 mm layered hypopyon, and a plaque on the posterior capsule that blocked direct exam of the posterior segment. Ultrasonography revealed extensive vitritis without retinal or choroidal detachments. CONCLUSION Endophthalmitis resolved and vision improved after management with vitreous tap, intravitreal and fortified topical antibiotics, and subsequent prompt pars plana vitrectomy. Vitreous sample grew fluoroquinolone-resistant staphylococcus epidermidis.

Abstract
PURPOSE To assess the nationwide rate of acute postoperative endophthalmitis (APE) after cataract extraction in Korea and to evaluate potential risk factors thereof. MATERIALS AND METHODS Nationwide insurance claims data from July 2014 to June 2017 were reviewed. All patients with phacoemulsification or extracapsular/intracapsular cataract extraction were included. Exclusion criteria were combined glaucoma surgery or total vitrectomy or when the patient had a history of intraocular foreign body. RESULTS In total, 1505103 cases (982203 patients) were included. APE developed in 953 cases (938 patients) with an overall incidence of 0.063%. After adjusting for possible confounding factors, male sex [odds ratio (OR) 1.42; 95% confidence interval (CI) 1.25-1.61; p<0.001], primary clinical setting, operations performed in non-major cities, usage of sutures (OR 2.82; 95% CI 2.13-3.74; p<0.001), anterior vitrectomy (OR 8.71; 95% CI 6.71-11.32; p<0.001), aphakic cataract surgery (OR 1.52; 95% CI 1.03-2.22; p=0.033), hypertension (OR 1.40; 95% CI 1.18-1.66; p<0.001), diabetes (OR 1.59; 95% CI 1.31-1.93; p<0.001), and chronic renal failure (OR 1.28; 95% CI 1.01-1.62; p=0.039) were found to be related to APE development. CONCLUSION The incidence of APE after cataract extraction was consistent with reports from other studies. Additional research is needed to determine the relationship of newly found risk factors, such as hypertension, primary clinical setting, chronic renal failure, and usage of suturing, with APE development.

Abstract
PURPOSE To compare the effectiveness of intravitreal injection of triamcinolone acetonide-moxifloxacin (Tri-Moxi) to a standard eyedrop regimen in controlling postoperative inflammation, corneal edema, and the rate of high intraocular pressure (IOP) among cataract patients. SETTING Loma Linda University Eye Institute, California, USA. DESIGN Retrospective longitudinal comparative study. METHODS The electronic medical records of patients who underwent cataract surgery using triamcinolone acetonide-moxifloxacin injection along with a postoperative nonsteroidal antiinflammatory drug drop were reviewed (Group 1). Group 1 was compared with patients who received a standard eyedrop (Group 2) in terms of intraocular inflammation and corneal edema severity, and the rate of high IOP, postoperatively. RESULTS A total of 1195 consecutive eyes (Group 1 [681 eyes], Group 2 [514 eyes]) of 919 patients were included in the study. The anterior chamber cell reaction severity decreased by 34.0% and 35.7% at 1 week and 1 month, respectively, after surgery following triamcinolone acetonide-moxifloxacin injection compared with standard eyedrop therapy (P = .001 and P = .02, respectively). Group 1 was associated with increased severity of corneal edema (odds ratio, 1.48; P = .001) on postoperative day 1, with no statistically significant difference at 1 week and 1 month postoperatively (P = .25 and P = .48, respectively). There was no statistically significant difference in the rate of high IOP between the two groups at different timepoints postoperatively. CONCLUSIONS Triamcinolone acetonide-moxifloxacin injection is an effective method to control intraocular inflammation after cataract surgery. It is a promising substitute for standard eyedrop therapy, especially for patients who have poor compliance with eyedrop usage.

Abstract
Post-operative endophthalmitis (POE) following cataract surgery is an uncommon, vision-threatening complication that has been reported to occur at rates of between approximately 0.03% and 0.2%. Prompt diagnosis and treatment of endophthalmitis is critical for minimizing vision loss, but most recent efforts have focused on the prophylactic administration of antibiotics to prevent the development of endophthalmitis. Surgeons from around the world have different topical and intracameral antibiotic usage patterns to prevent endophthalmitis, and to date no general consensus regarding best practice has emerged. Several studies have reported on the routine use of intracameral cefuroxime, moxifloxacin, and vancomycin, including a single randomized clinical trial by the European Society of Cataract and Refractive Surgery (ESCRS) in 2007. These studies have notable shortcomings, but many authors suggest that intracameral cefuroxime together with topical antibiotics probably decreases the risk of endophthalmitis. However, the deleterious effects of routine prophylactic antibiotics, which include toxicity, cost, and increasing antimicrobial resistance, among others, are noteworthy. In contrast, aseptic technique with pre-operative instillation of povidone-iodine remains the only technique supported by level I evidence to reduce the incidence of endophthalmitis. Although the routine use of intracameral antibiotics continues to increase throughout the world, data from multicenter, randomized, prospective trials is needed to provide better guidance regarding the prophylactic use of antibiotics.

Abstract
PURPOSE To review current and past practices of intracameral antibiotic administration for infection prophylaxis in cataract surgery; to review the benefits and liabilities of available prophylactic drugs, dosage determination, and administration protocols; and to devise an optimum dose and administration protocol for intracameral moxifloxacin. SETTING Humber River Hospital and the University of Toronto, Toronto, Ontario, Canada. DESIGN Retrospective evaluation of treatment modality. METHODS This study consisted of a detailed review of the history, drugs, and methods of intracameral prophylaxis and microbiological and pharmacodynamics analysis of options. A review of potential drug sources and doses was performed and 1 drug, dose, and administration protocol was selected. The current method's adoption reasons are described followed by the authors' experience. RESULTS A single infection in 3430 cases occurred with a moxifloxacin-resistant strain of Staphylococcus epidermidis when moxifloxacin 100 mcg in 0.1 mL was used. Increasing the dose and changing the administration technique resulted in no infections in 4601 cases and no detrimental side effects or complications. CONCLUSION Intracameral moxifloxacin prepared by dilution of 3 cc moxifloxacin 0.5% (Vigamox) with 7 cc balanced salt solution and with the administration of 0.3 to 0.4 cc (450 to 600 mcg.) as the final step in cataract surgery via the side port after the main incision has been sealed and hydrated showed advantages over alternative intracameral antibiotic prophylactic methods, with minimum risk.

Abstract
BACKGROUND The burden from non-communicable diseases and injuries (NCDI) in India is increasing rapidly. With low public sector investment in the health sector generally, and a high financial burden on households for treatment, it is important that economic evidence is used to set priorities in the context of NCDI. OBJECTIVE Our objective was to understand the extent to which economic analysis has been used in India to (1) analyze the impact of NCDI and (2) evaluate prevention and treatment interventions. Specifically, this analysis focused on the type of economic analysis used, disease categories, funding patterns, authorship, and author characteristics. METHODS We conducted a systematic review based on economic keywords to identify studies on NCDI in India published in English between January 2006 and November 2016. In all, 96 studies were included in the review. The analysis used descriptive statistics, including frequencies and percentages. RESULTS A majority of the studies were economic impact studies, followed by economic evaluation studies, especially cost-effectiveness analysis. In the costing/partial economic evaluation category, most were cost-description and cost-analysis studies. Under the economic impact/economic burden category, most studies investigated out-of-pocket spending. The studies were mostly on cardiovascular disease, diabetes, and neoplasms. Slightly over half of the studies were funded, with funding coming mainly from outside of India. Half of the studies were led by domestic authors. In most of the studies, the lead author was a clinician or a public health professional; however, most of the economist-led studies were by authors from outside India. CONCLUSIONS The results indicate the lack of engagement of economists generally and health economists in particular in research on NCDI in India. Demand from health policy makers for evidence-based decision making appears to be lacking, which in turn solidifies the divergence between economics and health policy, and highlights the need to prioritize scarce resources based on evidence regarding what works. Capacity building in health economics needs focus, and the government's support in this is recommended.

Abstract
Purpose The purpose of this article is to document the current practice pattern of Indian ophthalmologists for antibiotic prophylaxis in cataract surgery to prevent endophthalmitis. Methods Fifteen structured questions were sent online to all ophthalmologists registered with the All India Ophthalmological Society. The questionnaire was divided into three main categories of prophylaxis - preoperative, intraoperative, and postoperative. A web-based anonymous survey was conducted, and a unique response link allowed completing the survey only once. We compared the results with a similar 2014 survey among the members of the American Society of Cataract and Refractive Surgeons (ASCRS). Results The response was received from 30.2% (n = 4292/14,170) ophthalmologists. The results were as follows: all respondents do not prepare the eye with 5% povidone-iodine (83% of them use povidone iodine), majority (90%) use topical antibiotic both pre- and post-operatively, 46% use subconjunctival antibiotic at the end of surgery, and 40% use intracameral antibiotic (46% of them in high-risk patients only). Moxifloxacin was the preferred antibiotic for topical and intracameral use. Comparison with the 2014 ASCRS survey results showed a similarity in decision for pre- and post-operative antibiotics and intracameral antibiotic but dissimilarity in the choice of intracameral antibiotic and decision for subconjunctival antibiotic. Conclusion The antibiotic prophylaxis practice by the Indian ophthalmologists is not too dissimilar from the practice in North American Ophthalmologists (ASCRS) though all ophthalmologists in India must be nudged to preoperative preparation of the eye with povidone-iodine and discontinue the practice of postoperative subconjunctival and systemic antibiotic.
