Risk Factors for Legal Blindness in 237 Japanese Patients with Exogenous Endophthalmitis: A Multicenter Cohort Study from J-CREST. Ocul Immunol Inflamm 2024; 32:1133-1141. [PMID: 36701518 DOI: 10.1080/09273948.2023.2165111] [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: 07/16/2022] [Revised: 12/26/2022] [Accepted: 12/31/2022] [Indexed: 01/27/2023]
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.

[PMID: 38900438 PMCID: PMC11190831 DOI: 10.1001/jamaophthalmol.2024.1716] [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: 01/29/2024] [Accepted: 04/07/2024] [Indexed: 06/21/2024]
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.

Ocul Immunol Inflamm 2024; 32:796-802.

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.

[PMID: 39068247 DOI: 10.1038/s41433-024-03281-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 12/16/2023] [Accepted: 07/22/2024] [Indexed: 07/30/2024] Open
Abstract
BACKGROUND Cataract surgery remains the commonest ophthalmic surgical procedure in the UK. Post-operative endophthalmitis (POE) is a sight-threatening complication. This study presents the incidence and outcomes of POE within Moorfields Eye Hospital NHS Foundation Trust (MEH) in London, UK. METHODS We conducted a retrospective, tertiary-centre study of the incidence and outcomes of POE following elective phacoemulsification cataract surgery between 2015 and 2022. RESULTS We report a rate of 18 out of 154 826 (0.012%) cases of POE within seven weeks of cataract surgery. The age range was 43-87 years (mean age 67.1 years), and the male-to-female ratio was 1:1. Two cases were associated with intraoperative vitreous loss, one with anterior capsular tear extending to posterior capsular tear and the other with posterior capsular tear and dropped fragment. Two cases had a concomitant intravitreal injection, one of Triamcinolone Acetonide and the other of Dexamethasone implant (Ozurdex®), to manage chronic uveitic macular oedema. The majority of samples (89.9%) resulted in Gram-positive species. A final best corrected visual acuity (BCVA) of Snellen 6/36 or better was achieved in 12/18 (66.67%). The time from cataract surgery to suspicion of POE ranged from 3 to 44 days (mean 15.8 days). Eight cases (44.4%) required pars plana vitrectomy (PPV). CONCLUSIONS We demonstrate an incidence of POE of 0.012% following phacoemulsification at MEH from January 2015 to December 2022. Such results are a testament to high-quality surgery, training supervision and post-operative care whilst adhering to local and international standards.

Abstract
Infectious endophthalmitis is a severe ophthalmic emergency. This infection can be caused by bacteria and fungi. For efficient treatment, the administration of antimicrobial drugs to which the microbes are susceptible is essential. The aim of this study was to identify micro-organisms in biopsies of Mexican endophthalmitis patients using metagenomic next-generation sequencing and determine which antibiotic resistance genes were present in the biopsy samples. In this prospective case study, 19 endophthalmitis patients were recruited. Samples of vitreous or aqueous humour were extracted for DNA extraction for metagenomic next-generation sequencing. Analysis of the sequencing results revealed the presence of a wide variety of bacteria in the biopsies. Resistome analysis showed that homologues of antibiotic resistance genes were present in several biopsy samples. Genes possibly conferring resistance to ceftazidime and vancomycin were detected in addition to various genes encoding efflux pumps. Our findings contrast with the widespread opinion that only one or a few bacterial strains are present in the infected tissues of endophthalmitis patients. These diverse communities might host many of the resistance genes that were detected, which can further complicate the infections.

Abstract
Objective The objective of this study was to assess the feasibility of using an intracameral phenylephrine/ketorolac infusion during cataract surgery as a single agent to prevent postoperative pain, inflammation, and other complications. Methods A prospective, single-group feasibility study was conducted in which phenylephrine/ketorolac infusion was administered during cataract surgery and no perioperative topical drops were initially prescribed. Patients underwent optical coherence tomography, corrected distance visual acuity testing, and slit lamp biomicroscopy examination at perioperative visits, during which they also reported symptoms of pain, irritation, and/or photophobia. A goal adverse event (AE) rate was set at ≤5.0%. Results A total of 94 eyes (60 patients) were included in this study. The AE rate was 13.8% (13/94 eyes) with pain/irritation in eight eyes, cystoid macular edema (CME) in three eyes, and corneal edema in three eyes. Conclusions Based on an AE rate goal of ≤5.0%, using intraoperative, intracameral phenylephrine/ketorolac alone was not deemed a feasible alternative to current postoperative eye drop regimens in our clinical setting. However, a 13.8% AE rate is comparable to the rates of postoperative CME, corneal edema, pain, and irritation in the published literature. Thus, more research is needed to truly define this approach as inferior or non-inferior to the current standard of care.

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
Topical antimicrobials and antiseptics are used perioperatively to reduce the ocular surface bacteria flora (OSBF) that are involved in the development of post-operative infectious complications. However, their effectiveness is still a controversial topic. This systematic review, performed according to the PRISMA guidelines and registered in PROSPERO, aims to provide an overview of the efficacy of the agents currently used in peri-cataract surgery and -intravitreal injections (IVI) in lowering the OSBF. Although effective in lowering OSBF, perioperative topical antimicrobials are associated with the risk of resistance development, with no obvious additional benefit compared with topical antisepsis. Conversely, the effectiveness of topical antiseptics before cataract surgery and IVI is strongly supported. Based on the available evidence, perioperative antimicrobials are not recommended, whereas the perioperative use of antiseptics is strongly recommended as prophylactic treatment for lowering the infection due to OSBF. Post-operative antimicrobials may be considered in eyes at higher risk for infection.

Abstract
Background Bacterial endophthalmitis is an acute progressive visual threatening disease and one of the most important causes of blindness worldwide. Current treatments are unsatisfactory due to the emergence of drug-resistant bacteria and the formation of biofilm. Purpose The aim of our research was to construct a novel nano-delivery system with better antimicrobial and antibiofilm effects. Methods This study developed a novel antibiotic nanoparticle delivery system (MXF@UiO-UBI-PEGTK), which is composed of (i) moxifloxacin (MXF)-loaded UiO-66 nanoparticle as the core, (ii) bacteria-targeting peptide ubiquicidin (UBI29-41) immobilized on UiO-66, and (iii) ROS-responsive poly (ethylene glycol)-thioketal (PEG-TK) as the surface shell. Then the important properties of the newly developed delivery system, including biocompatibility, toxicity, release percentage, thermal stability, ability of targeting bacteria, and synergistic antibacterial effects on bacterial biofilms and endophthalmitis, were evaluated. Results In vitro, MXF@UiO-UBI-PEGTK exhibited significant antibiotic effects including the excellent antibiofilm property against Staphylococcus aureus, Pseudomonas aeruginosa, and methicillin-resistant Staphylococcus aureus at high levels of ROS. Moreover, MXF@UiO-UBI-PEGTK demonstrated outstanding efficacy in treating bacterial endophthalmitis in vivo. Conclusion This novel nanoparticle delivery system with ROS-responsive and bacteria-targeted properties promotes the precise and effective release of drugs and has significant potential for clinical application of treating bacterial endophthalmitis.

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
Acute post-cataract surgery endophthalmitis (APSE) is a serious vision-threatening complication of cataract surgery. Analysis of the management and prognosis in cases of APSE may provide better guidance for future treatment. Fifty-six patients (56 eyes) diagnosed with APSE between 2013 and 2022 were retrospectively reviewed. The incidence of APSE rate was 0.020% (95% CI: 0.011-0.029%). Intraocular cultures were positive in 18 (32.1%) cases, with 21 organisms isolated. Coagulase-negative staphylococci was the predominant isolate (12/21; 57.1%). The time from surgery to the onset of endophthalmitis was 7 days (interquartile range: 3-16) in patients with good best-corrected visual acuity (BCVA) (≥20/70) and 3 days (interquartile range: 1-8) in those with poor BCVA (<20/70). Multivariate linear regression analysis revealed that initial BCVA (logMAR) (p < 0.001), time from onset to initial intravitreal antibiotics (IVAs) (p < 0.001), and positive culture of highly virulent pathogens (p = 0.018) displayed significantly positive associations with the final BCVA (logMAR). Adjunctive use of intravitreal corticosteroids and systemic antibiotics were unrelated to a favorable final BCVA. In conclusion, the severity of the visual condition at baseline, as well as delayed treatment, are risk factors for poor visual outcomes in APSE.

Abstract
BACKGROUND/AIMS To assess the frequency of immediate sequential bilateral cataract surgery (ISBCS) and endophthalmitis during 13-year period in Tays Eye Centre, Tampere University Hospital, Tampere, Finland. METHODS All cataract surgeries performed between 1 January 2008 and 31 December 2020, and all endophthalmitis cases during the same period were searched from electronic patient records. Numbers and frequencies of ISBCS, and complications, including endophthalmitis and vitreous loss, were recorded and compared with unilateral operations. RESULTS The study included 56 700 cataract surgeries in 34 797 patients of whom 39% (n=13 445) had ISBCS. The median age of the patients was 75 (IQR 68-80, range 0.08-99) years at the time of surgery. The proportion of ISBCS patients increased from 4.2% in 2008 to 46% in 2020. Vitreous loss occurred in 480 (0.9%) of cataract surgeries. There were no postoperative endophthalmitis after cataract surgery (n=0) during the 13-year period. CONCLUSION The proportion of patients undergoing ISBCS increased from 4.2% in 2008 to 46% in 2020. No endophthalmitis were found to be associated with ISBCS.

Abstract
Periodic assessment of bacterial contamination is necessary as it allows proper guidance in cases of eye infections through the use of appropriate antibiotics. Due to the extensive use of antibiotic treatment, many strains of the microbiota that cause infections are resistant to the usual ophthalmic antibiotics. The present study provides an updated assessment of the susceptibility of Gram-positive and Gram-negative bacteria found on the ocular surface to the most commonly used antibiotic agents in patients undergoing cataract surgery. A total of 993 patients were included in the study with ages between 44 and 98 years old. Conjunctival cultures were collected 7 days before cataract surgery. The response of Gram-positive and Gram-negative bacteria to various antibiotic classes, such as glycopeptides, cephalosporins, carbapenems, fluoroquinolones, aminoglycosides, phenicols, tetracyclines, rifamycins, macrolides and penicillins, was assessed. From the tested antibiotics, vancomycin had 97.8% efficacy on Gram-positive bacteria. In the cephalosporin category, we observed a high level of resistance of the cefuroxime for both Gram-positive and negative bacteria. Antibiotics that have more than 90% efficacy on Gram-positive bacteria are meropenem, imipenem, netilmicin, amikacin and rifampicin. On Gram-negative bacteria, we found 100% efficacy of all tested fluoroquinolones, i.e., aminoglycosides (except for tobramycin), doxycycline, azithromycin, clarithromycin and chloramphenicol. The current study illustrates patterns of increased resistance in certain bacteria present on the ocular surface to some of the commonly used antibiotics in ophthalmological clinical practice. One such revealing example is cefuroxime, which has been highly used as an intracameral antibiotic for the prevention of bacterial endophthalmitis after cataract surgery.

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
Infectious endophthalmitis is a severe intraocular infection caused by bacteria, or less commonly by fungi. It can occur after penetrating eye procedures, trauma, or the spread of infection from contiguous structures or via emboli from distant organs. Because of the time-critical nature of the treatment, endophthalmitis is treated with the clinical diagnosis and modified by the microbiological report of the intraocular contents. The current strategy for managing endophthalmitis relies on pre-clinical literature, case series, and one large multi-center randomized clinical trial on post-cataract surgery endophthalmitis. Culture-susceptibility of the microorganisms from undiluted vitreous guides the definitive treatment in non-responsive cases. Strategies to reduce the incidence of endophthalmitis after penetrating eye procedures have been developed concurrently with refined means of treatment. Despite these advances, outcomes remain poor for many patients. Although consensus articles have been published on managing endophthalmitis, treatment patterns vary, and controversies remain. These include (1) the use of newer methods for early and precise microbiological diagnosis; (2) the choice of intravitreal antibiotics; (3) the need for systemic therapy; (4) early and complete vitrectomy. Here, we review the current consensus and address controversies in diagnosing and managing endophthalmitis. This review is intended to familiarize physicians and ophthalmologists with different aspects of endophthalmitis management to make informed decisions.

Abstract
Our purpose was to compare postoperative infectious endophthalmitis rates before and after the introduction of antibiotic prophylaxis via intracameral with cefuroxime (ATB-P IC) in a high-volume cataract surgery service. Retrospective cohort study considering patients who underwent cataract surgery at Ophthal Hospital Especializado, São Paulo, Brazil, from January/2011 to December/2019. Patients operated from 2013 to 2019 comprised the ATB-P IC group while those operated from 2011 to 2013 formed the control group without the ATB-P IC protocol. A total of 23,184 cataract surgeries were included, with 6,207 in the Control Group and 16,977 in the ATB-P Group. A significantly higher rate of endophthalmitis was observed in the control group (0.0967%) when compared to the ATB-P group (0.0177%) (p = 0.014). Surgeries performed with ATB-P showed 80% less chance of reported endophthalmitis (OR = 0.20; 95% CI 0.05-0.72; p = 0.014) than those without ATB-P. Of the six cases confirmed by culture in the control group, all tested positive for Pseudomonas aeroginosa and the only case confirmed by culture in the ATB-P group was positive for Staphylococcus epidermidis. Our findings strongly support the use of intracameral antibiotic prophylaxis with cefuroxime to reduce postoperative infectious endophthalmitis rates, and we recommend its incorporation into cataract surgery protocols.

Abstract
Moxifloxacin solution is frequently injected at the conclusion of cataract surgery for endophthalmitis prophylaxis. 2 different concentrations are most commonly available in the United States for intracameral (IC) use: 0.5% (5 mg/mL) and 0.1% (1 mg/mL). The recommended volume to be injected is different for the 2 concentrations, and incorrect dosing can increase the risk of toxic anterior segment syndrome or endophthalmitis. In addition, the U.S. Food and Drug Administration recently published an alert regarding potential adverse events associated with intraocular compounded moxifloxacin. This clinical advisory reviews the optimal dosing of IC moxifloxacin based on current evidence.

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.

Thermosensitive Intravitreal In Situ Implant of Cefuroxime Based on Poloxamer 407 and Hyaluronic Acid. Gels 2023; 9:693. [PMID: 37754374 PMCID: PMC10530203 DOI: 10.3390/gels9090693] [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: 07/31/2023] [Revised: 08/22/2023] [Accepted: 08/25/2023] [Indexed: 09/28/2023] Open
Abstract
The main method of treatment and prevention of endophthalmitis is a combination of intravitreal and topical administration of antibiotics, such as cefuroxime moxifloxacin or vancomycin. However, this method is ineffective due to the rapid elimination of the drug. This problem can be solved with the help of intravitreal in situ injection systems, which are injected with a syringe into the vitreous body and provide prolonged action of the drug at the focus of inflammation. Under the influence of temperature, the liquid drug undergoes a phase transition and turns into a gel after injection. This ensures its prolonged action. The study aimed to develop an intravitreal in situ cefuroxime delivery system for the treatment of endophthalmitis based on a thermosensitive biodegradable composition of poloxamer 407 and hyaluronic acid. A combination of poloxamer Kolliphor® P407, Kolliphor® P188, and PrincipHYAL® hyaluronic acids of different molecular weights was used as a delivery system. The potency of cefuroxime solid dispersion with polyvinylpyrrolidone-10000, polyethylene glycol-400, and polyethylene glycol-1500 in a 1:2 ratio was studied for prolonged action compared to cefuroxime substance. The experimental formulations were studied for the parameters of gelation temperature in a long-term test (4 months), pH, and release of cefuroxime using dialysis bags. To study the distribution parameter in the vitreous body, an in vitro model (1/13) was developed, which was a hollow agar sphere filled with 1% (w/v) polyacrylate gel. For the superior formulations, a HET-CAM test (chorioallantoic membrane test) was performed to determine the absence of irritant effects. According to the study results, a formulation containing a solid dispersion of cefuroxime:PEG-400 (1:2), the matrix of which contained 18% (w/v) Kolliphor® P407 poloxamer, 3% (w/v) Kolliphor® P188 poloxamer, and 0.5% (w/v) hyaluronic acid (1400-1800), was selected. This sample had an average gelation temperature of 34.6 °C, pH 6.7 ± 0.5, and a pronounced prolonged effect. Only 7.6% was released in 3 h of the experiment, whereas about 38% of cefuroxime was released in 72 h. No irritant effect on the chorioallantoic membrane was observed for any formulations studied.

Abstract
BACKGROUND To describe the preferred cataract surgery practices among Malaysian ophthalmologists and medical officers in comparison with the recommended practices. METHODS An online questionnaire was sent out in April 2021, to Malaysian Ophthalmologists and medical officers who perform cataract surgeries. The questions were focused on the preferred cataract surgery practices of the participants. All data obtained were collected, tabulated and analysed. RESULTS A total of 173 participants responded to the online questionnaire. 55% of the participants were within 31-40 years of age. 56.1% preferred peristaltic pump over venturi system. 91.3% of participants practised povidone iodine instillation to the conjunctival sac. With regards to the main wound incision, more than half of the surgeons (50.3%) preferred fixed superior incision and 72.3% of them preferred 2.75 mm microkeratome blade. Most of the participants (63%) were inclined towards C-Loop clear intraocular lens (IOL) with a single-handed push preloaded system. 78.6% of the surgeons routinely use carbachol in their cataract surgery. CONCLUSIONS This survey provides some insight into the current practices among Malaysian ophthalmologists. Most of the practices are in line with international guidelines for preventing postoperative endophthalmitis. This article could help trainees and ophthalmologists benchmark and observe the common cataract surgery practices among their seniors and peers in Malaysia.

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.

Abstract
Objective To evaluate the effect of gentamicin in surgical perfusion solution on endophthalmitis incidence after cataract surgery. Methods A retrospective analysis of endophthalmitis incidence was conducted in two groups of patients who underwent cataract surgery, with (Group B) or without gentamicin (Group A) in the surgical perfusion solution. Endophthalmitis incidence, the isolated pathogenic bacteria strains and their antibiotic sensitivity, and the drug-resistant genotype of the pathogens were examined. Results The incidence of endophthalmitis in patients of group A was 0.8‰. Thirteen pathogenic bacterial strains were isolated from the patient samples in group A, including 8 strains of Staphylococcus epidermidis, 1 Staphylococcus aureus, 1 Streptococcus pneumoniae, 1 Streptococcus bovis, 1 Enterococcus faecium and 1 Morganella sp. The incidence of endophthalmitis in group B patients was 0.2‰, which was significantly lower than that in group A (P<0.05). Five strains of pathogenic bacteria were successfully isolated, including 2 strains of Enterococcus faecium, 1 Enterococcus faecalis, 1 Staphylococcus epidermidis and 1 Staphylococcus aureus. There was no significant difference in the proportion of Staphylococcus strains in all isolated bacteria between the two groups (P > 0.05). However, the proportion of Enterococci isolated in group B samples was higher than that in group A (P < 0.05). There were more gentamicin-sensitive strains than levofloxacin-sensitive strains identified (P < 0.05). Interestingly, aminoglycoside-inactivating enzyme resistance gene was detected in Enterococcus strains. Conclusion Our data suggest that gentamicin-containing perfusion solution can reduce the incidence of postoperative endophthalmitis in cataract patients. However, the selective pressure imposed by gentamicin may facilitate the development of aminoglycoside-resistant Enterococcos strains.

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
Ocular surgery encompasses a wide range of procedures, including surgery of the tear ducts, eyelid, cornea and conjunctiva, lens, ocular muscle, and vitreoretinal and iris surgery. Operations are also performed for the removal of tumors, repairs of ocular trauma and, finally, corneal transplantation. Antibiotic prophylaxis for the prevention of surgical site infections (SSIs) in ocular surgery is a complex field in which shared lines of action are absent. In light of the scarcity of shared evidence in the use of ocular antimicrobial prophylaxis for the pediatric population, this consensus document aims to provide clinicians with a series of recommendations on antimicrobial prophylaxis for patients of neonatal and pediatric age undergoing eye surgery. The following scenarios are considered: (1) intraocular surgery; (2) extraocular surgery; (3) ocular trauma; (4) ocular neoplasm; (5) ocular surface transplantations; (6) corneal grafts. This work has been made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies and represents, in our opinion, the most complete and up-to-date collection of recommendations regarding clinical actions in the peri-operative environment in eye surgery. The application of uniform and shared protocols aims to improve surgical practice, through the standardization of procedures, with a consequent reduction of SSIs, also limiting the phenomenon of antimicrobial resistance.

Abstract
INTRODUCTION To demonstrate efficacy and safety of an ophthalmic hydrogel formulation of netilmicin/dexamethasone, containing xanthan gum twice a day (b.i.d.) versus netilmicin/dexamethasone eye drops four times a day (q.i.d) to treat inflammation and prevention of infection after cataract surgery. METHODS Patients undergoing phacoemulsification with intraocular lens implantation (IOL) were randomised in two groups: group 1, twice daily (b.i.d.) dexamethasone 0.1%/netilmicin 0.3% (Netildex) ophthalmic gel; group 2, four times daily (q.i.d.) dexamethasone 0.1%/netilmicin 0.3% (Netildex) eye drops. Both treatments were administered for 14 days after surgery. Patients were evaluated before surgery, on the day of surgery and at 1, 7, 15 and 60 postoperative days. The primary efficacy endpoint was evaluation of cellularity and flare in the anterior chamber through slit-lamp biomicroscopy 7 days after surgery. Secondary endpoints included: presence of signs/symptoms of postoperative ocular inflammation and incidence of infection. RESULTS One hundred seventy-three patients were randomised and 168 were evaluable. Flare and cellularity were resolved at day 7 in 92.5% of patients and almost completely by day 15. In both intent to treat (ITT) and per-protocol (PP) populations, the efficacy analysis demonstrated that the gel formulation administered twice a day was non-inferior to the eye drops administered four times a day. For ITT analysis, the lower limit of the 97.5% confidence interval (- 0.0535) was greater than the non-inferiority limit of -0.10. For the PP analysis, the lower limit of the 97.5% confidence interval (- 0.0526) was greater than the non-inferiority limit of - 0.10. The patient's global tolerability and reported symptoms were similar between treatment groups. No microbial load and no safety events were observed. CONCLUSIONS Efficacy of the gel reduced posology (twice a day) is not inferior to four times a day eye drops. Both treatments were well tolerated and efficacious. The new reduced posology hydrogel formulation may improve patient compliance and quality of life. TRIAL REGISTRATION Eudract: 2016-0021138-63; ClinicalTrial.gov: NCT029738880.

Abstract
In an online survey of >1200 global cataract surgeons, 66% were using intracameral (IC) antibiotic prophylaxis. This compared with 50% and 30% in the 2014 and 2007 surveys, respectively. Irrigation bottle infusion and intravitreal injection was each used by only 5% of respondents. For IC antibiotics, vancomycin was used by 6% in the United States (52% in 2014), compared with 83% for moxifloxacin (31% in 2014). Equal numbers used compounded moxifloxacin or the Vigamox bottle as the source. There was a decrease in respondents using preoperative (73% from 85%) and postoperative (86% from 97%) topical antibiotic prophylaxis; the latter was not used by 24% of surgeons injecting IC antibiotics. Reasons cited by those not using IC antibiotics include mixing/compounding risk (66%) and being unconvinced of the need (48%). However, 80% believe having a commercially approved IC antibiotic is important; if reasonably priced, this would increase adoption of IC prophylaxis to 93%.

Abstract
Intracameral cefuroxime has been associated with postoperative macular edema and sub-retinal fluid. To date, nearly all published cases are attributed to errors in antibiotic dilution, leading to administration of supratherapeutic doses. We report three cases of postoperative macular edema and subretinal fluid following a standard dose of 1 mg/0.1 mL of cefuroxime at the end of cataract surgery. Distinguishing features of these cases were intraoperative zonular instability and history of vitrectomy. We hypothesize that certain factors may increase the risk of cefuroxime-associated retinal toxicity, including history of vitrectomy, zonular compromise, posterior capsular break, surgery for a secondary intraocular lens, and unicameral state.

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 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
Purpose: Intracameral antibiotics are known to reduce the incidence of acute endophthalmitis. Various drugs are available for intracameral use. This prospective study was carried out to compare the efficacies of intracameral cefuroxime and moxifloxacin prophylaxis in reducing the incidence of acute endophthalmitis after cataract surgery in rural India. Methods: This was a prospective, nonrandomized, comparative, interventional study. Between October 2016 and March 2018, 15 eye care facilities spread over four Indian states were preselected to use either of the intracameral antibiotics, cefuroxime or moxifloxacin, following cataract surgery (phacoemulsification or manual small incision cataract surgery, SICS). The main outcome measure was the occurrence of acute clinical endophthalmitis within six weeks of the surgery. This was compared with the earlier rate of endophthalmitis in the same locations. Results: The study was done in 42,466 eyes. Of the total, 42.2% received intracameral cefuroxime and 57.8% received intracameral moxifloxacin. SICS was performed more often. Clinical acute endophthalmitis occurred in 15 eyes. This accounted to a 72.22% reduction, from the earlier 0.126% to 0.035%, of postcataract surgery acute endophthalmitis. The reduction in the incidence of endophthalmitis after intracameral cefuroxime was 0.017% and that after intracameral moxifloxacin was 0.049%. With either intracameral antibiotics, the reduction in incidence was statistically significant (P < 0.001), but not between the molecules. Intracameral cefuroxime showed 66.67% reduction and intracameral moxifloxacin showed 74.74% reduction. Conclusion: A 3.6-fold decrease in postcataract surgery endophthalmitis was observed upon the use of intracameral antibiotics in rural India. Both intracameral cefuroxime and moxifloxacin proved efficacious.

Abstract
BACKGROUND Acute post-cataract endophthalmitis (APE) is a rare complication potentially causing irreversible visual loss. A 10-year study of APE was conducted to determine its incidence, microbiological spectra and antibiotic resistance profile of APE-related pathogens at a major tertiary referral center in Brazil. METHODS APE cases reported between January 2010 and December 2019 were included. Phacoemulsification and extracapsular cataract techniques were eligible; combined procedures, traumatic and congenital cataract were excluded. Vitreous samples were cultured and antimicrobial resistance was compared for the periods of 2010-2014 and 2015-2019. The results were analyzed with Fisher's exact test. RESULTS Our sample consisted of 40,491 cataract surgeries and 51 (0.126%) APE cases. Culture was positive in 35 cases (71.4%), of which 31 (88.6%) Gram-positive, 3 (8.6%) Gram-negative, and 1 (2.9%) fungal. The most frequently isolated organism was Staphylococcus epidermidis (n = 17/35, 48.6%), followed by Staphylococcus aureus (n = 4/35, 11.4%). From 2010-2014 to 2015-2019, antimicrobial resistance increased against moxifloxacin (11.1-54.5%, p = 0.07), ciprofloxacin (54.5-72.7%, p = 0.659) and oxacillin (66.7-93.3%, p = 0.13). CONCLUSIONS The observed incidence and microbial spectra were compatible with previous studies. A trend towards growing moxifloxacin and ciprofloxacin resistance was observed. Surveillance remains crucial to prevent treatment failure from antimicrobial resistance.

Abstract
OBJECTIVE To determine how supplemental perioperative topical or oral moxifloxacin administration impacts anterior chamber (AC) antibiotic concentrations beyond those achieved by intracameral (IC) administration alone for postoperative endophthalmitis (POE) prophylaxis. DESIGN Mathematical modeling. METHODS The mathematical model developed by Arshinoff, Modabber, and Felfeli was adapted to calculate all reported data. A literature review of pharmacokinetic data for topical and oral moxifloxacin was used to inform the expansion of the model. RESULTS Our previously constructed IC model yields a dose of moxifloxacin in the AC sufficient to confer bactericidal coverage against the most common POE pathogen, methicillin-sensitive Staphylococcus aureus (MSSA), for ∼40 hours postoperatively. Topical 0.5% moxifloxacin eye drops alone, administered every 4 or 6 hours, achieve an AC concentration just above or at the mutant prevention concentration (MPC) for MSSA, respectively, whereas 8-hour dosing produces levels generally below the MPC. Combining topical moxifloxacin with IC increases the AC concentration above IC alone only after 20 or more hours and maintains the AC concentration at, or just below, the MPC for MSSA for as long as the drops are continued. Combined perioperative oral moxifloxacin with IC increases AC levels over IC alone only after 16 hours and maintains the AC concentration above the MPC for MSSA for an additional 5 hours, owing to the systemic reservoir. CONCLUSIONS The addition of topical or oral moxifloxacin supplemental to IC can extend the duration of bactericidal coverage for the most common, but not the most resistant POE-causing pathogens.

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
BACKGROUND To describe the incidence, clinical characteristics, and treatment outcomes of endophthalmitis after pars plana vitrectomy (PPV) with recycled single-use devices. The recommended sterilization process as well as safety measures are discussed. METHODS Medical charts of patients who developed endophthalmitis after PPV were retrospectively reviewed and reported in a descriptive manner. Cases undergoing PPV for preexisting endophthalmitis or open globe injury were excluded. Data collection included patient demographics, operative details, ocular findings, microbiological profiles, treatment modalities, and visual outcomes. RESULTS Over the past thirteen years, a total of 12,989 pars plana vitrectomy operations were included. In total, 13 eyes of 13 cases (0.10%) experienced endophthalmitis after vitrectomy. These occurred in 3 cases (0.11%) using 20-gauge vitrectomy compared to 8 cases (0.09%) using 23-gauge vitrectomy and 2 cases (0.18%) using 25-gauge vitrectomy. There were no statistically significant differences between the 20-gauge and microincisional vitrectomy surgery (MIVS) group (P = 0.64), and the 23- and 25-gauge approach (P = 0.34). Causative pathogens were positive by culture in 5 cases (45%): 3 g-positive cases, 1 g-negative case, and 1 fungus case. CONCLUSIONS The rate of endophthalmitis in patients who underwent 23-gauge PPV was comparable to those who underwent 25-gauge PPV. With our standardized protocol for instrument sterilization, endophthalmitis rates in those undergoing PPV using recycled single-use instruments were within the range of previously published results in which vitrectomy tools were disposed of after one use.

Abstract
OBJECTIVE To evaluate the efficacy and safety of the bilateral simultaneous XEN (BISIXEN) surgery in open-angle glaucoma patients. METHODS Retrospective analysis of a prospective data base conducted on uncontrolled glaucoma patients who underwent BISIXEN surgery. Primary endpoint measure was the incidence of sight-threatening complications. Secondary endpoints included intraocular pressure (IOP) reduction and in number of required antiglaucoma medications. RESULTS Ten patients (20 eyes) were included in the analysis. Median (95% confidence interval) follow-up was 12.0 (7.0-12.0) months, with 14 eyes having a follow-up of 12 months. No sight-threatening complications, such as endophthalmitis, retinal detachment, corneal decompensation, or intraocular hemorrhages were observed in any eye of study sample. Mean IOP decreased significantly from 25.2 (21.5-28.9) mm Hg at baseline to 15.1 (13.4-16.8) mm Hg at the last follow-up visit (p = 0.0001). Mean number of antiglaucoma medications was significantly reduced from 2.9 (2.5 to 3.3) drugs at baseline to 0.40 (0.00-0.70) at the end of the study (p < 0.0001). At the last study visit, 14 (70.0%) eyes had an IOP ≥ 6 and ≤ 18 mm Hg without treatment. Two eyes needed surgical revision and three ones needed a new glaucoma surgery: two underwent Ahmed valves (one eye with aniridia and the other previously operated on) and one underwent non-penetrating deep sclerectomy. CONCLUSIONS Bilateral simultaneous XEN implantation may be a feasible strategy in those patients with high anesthetic risk.

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
Purpose To demonstrate the visual outcomes of a foldable, hydroxy ethyl-methacrylate, single-piece, posterior chamber phakic intraocular lens (pIOL). Study Type Retrospective study. Materials and Methods Patients presenting with moderate to high myopia who underwent surgical correction with a posterior chamber phakic IOL (refractive intraocular lens, phakic intraocular lens, Appasamy Associates, Chennai, India) were retrospectively reviewed. Only patients with at least one-year follow-up were included. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell density (ECD), and pIOL vault were analyzed 1, 3, 6, and 12 months after surgery. Intraoperative and postoperative events were recorded in all cases. Results The study included 30 eyes from 15 patients. The mean patient age was 25.8 ± 3 years. The spherical equivalent of manifest refraction was −11.47 ± 4.38 D preoperatively and −0.44 ± 0.55 D postoperatively. The preoperative CDVA was 0.17 ± 0.12 logMAR. The postoperative UDVA was 0.053 ± 0.11 logMAR (min: −0.17 and max: 0.2) and 0.019 ± 0.091 logMAR (min: −0.17 and max: 0.2) at the end of 1 month and 6 months, respectively. At the end of the 12-month visit, the postoperative UDVA was 0.032 ± 0.094, and the safety index was 2.42. The mean ECD was 2639 cells/mm2 (min: 2389 and max: 2993 with SD: 139.53) at the preoperative visit and 2445 cells/mm2 (min: 2050 and max: 2701) at the 12-month visit (5.8% loss, p less than 0.001). ECD loss from 6 months to 12 months was not statistically significant. No significant cataract formation, significant endothelial cell loss, glaucoma, uveitis, or any other vision-threatening complication were observed. Conclusion Based on postoperative experience, we found that RIL phakic IOLs are safe and effective for treating high myopia at short-term follow-up.

The Anterior Chamber Injection of Moxifloxacin Injection to Prevent Endophthalmitis after Cataract Surgery: A Meta-analysis. J Ophthalmol 2020; 2020:7242969. [PMID: 32908685 PMCID: PMC7468651 DOI: 10.1155/2020/7242969] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 05/17/2020] [Accepted: 06/19/2020] [Indexed: 11/17/2022] Open
Abstract
Purpose A meta-analysis was performed to compare the efficacy of an anterior chamber injection of moxifloxacin in the prevention of endophthalmitis after cataract surgery. Methods A computer-based search of PubMed, Embase, the Cochrane Library, and the Clinical Trial database for articles related to anterior intraventricular injection of moxifloxacin for the prevention of endophthalmitis after cataract surgery was performed through April 2019. Study selection, data exclusion, and quality assessment were performed by two independent observers. Statistical analysis for the meta-analysis was performed by RevMan5.3 software. Results Eight studies were included, with a total of 123,819 eyes. The meta-analysis showed that an anterior chamber injection of moxifloxacin can prevent the incidence of endophthalmitis after cataract surgery (OR = 0.29, 95% CI (0.15, 0.56), P=0.0002), and the difference was statistically significant. There were no significant differences between the moxifloxacin injection and nonmoxifloxacin injection groups in regard to UCVA (log MAR) (SMD = −0.13, 95% CI (−0.62, 0.35), P=0.60), BCVA (log MAR) (SMD = −0.27, 95% CI (−1.28, 0.74), P=0.60), IOP (SMD = −0.04, 95% CI (−0.02, 0.01), P=0.22), corneal edema (OR = 1.03, 95% CI (0.23, 4.69), P=0.97), CCT (SMD = −0.01, 95% CI (−0.07, 0.05), P=0.77), or ECD (SMD = 0.00, 95% CI (−0.06, 0.07), P=0.94). Conclusion An anterior chamber injection of moxifloxacin can effectively prevent the incidence of endophthalmitis after cataract surgery, while the moxifloxacin injection and nonmoxifloxacin injection groups had similar results in regard to UCVA (log MAR), BCVA (log MAR), IOP, corneal edema, CCT, and ECD.

Abstract
PURPOSE We aimed to compare the local effects of intracameral cefuroxime diluted in normal saline (SF groups) against those of cefuroxime in balanced salt solution (BSS group) on the cornea of rabbits. MATERIALS AND METHODS Fourteen New Zealand albino rabbits were randomised into two groups. The right eyes of the rabbits in the SF group I were injected intracamerally with 1 mg cefuroxime diluted with 0.1 mL normal saline (n = 7), whereas the right eyes of the BSS group II were injected with 1 mg intracameral cefuroxime diluted with 0.1 mL with balance salt solution, and the left eyes of all rabbits received no treatment group III (control group). Corneal thickness was measured with pachymetry before and 1 week after the injection. Corneal samples were evaluated with light, specular and electron microscopy. RESULTS Mean endothelial cell count was lower in the SF than in the BSS and control groups. Although an increase in corneal thickness was found in both treatment groups, this was not the case for the control group. The corneal endothelium preserved its hexagonal structure in all groups. Although both treatment groups showed a loss of endothelial microvilli, this was more prevalent in the SF group. However, microvilli were preserved in the control group. Dissolution of tight junctions in corneal endothelium was observed in the SF group only. Mitochondrial swelling, coarsening of endoplasmic reticulum, cytoplasmic vacuolisation, and increased endothelial cell sizes were the same in both treatment groups but was not observed in the control group. Thicker and more oedematous corneal stroma were observed in the SF group compared with the BSS and control groups. CONCLUSION Dilution of intracameral cefuroxime in BSS yielded superior results compared with dilution in normal saline owing to toxicity to the endothelial cells and decline in the endothelial cell number, resulting in intracellular and intercellular morphological changes. BSS or any other solution with proven safety should be used in clinical studies.

Abstract
Purpose To qualitatively evaluate the ocular and periocular distribution of 14C-latanoprost following a single intracameral administration or repeated topical ocular administration in beagle dogs and cynomolgus monkeys. Methods In the dog study, three animals received an intracameral dose of 14C-latanoprost bilaterally and were euthanized at 1, 2, and 4 h post dose; three control animals received topical 14C-latanoprost bilaterally once daily for 5 days and were euthanized at 1, 4, and 24 h post final dose. Sagittal 40-µm sections of eyes with surrounding tissues were collected and processed for autoradiography. Methods in the monkey study were similar; two animals received a unilateral intracameral dose of 14C-latanoprost. Results After intracameral dosing in dogs, radioactivity was concentrated in the cornea, iris, ciliary body, and anterior chamber with no radioactivity detected in the eyelids or other periorbital tissues. After topical dosing, radioactivity was distributed in the bulbar conjunctiva, cornea, anterior chamber, iris, ciliary body, upper and lower eyelids, and periorbital tissues (fat/muscle). After intracameral dosing in monkeys, radioactivity was concentrated in the anterior chamber, cornea, iris, ciliary body, and posteriorly along the uveoscleral outflow pathway; there was no radioactivity in the eyelids or periorbital tissues aside from signal in the nasolacrimal duct, likely from reflux of 14C-latanoprost into the tear film. Conclusions Intracameral delivery resulted in more selective target tissue drug exposure. Intracameral drug delivery has potential to reduce ocular surface and periocular adverse effects associated with topical administration of prostaglandin analogues, such as eyelash growth and periorbital fat atrophy.

Abstract
Purpose Acute-onset postoperative endophthalmitis usually compromises the visual function and anatomical integrity of the eye. The aim of this study was to evaluate the efficacy of intraoperative cefuroxime use in irrigating solution on prevention of acute-onset endophthalmitis after phacoemulsification. Methods This retrospective, comparative, interventional cohort study included patients who underwent phacoemulsification between January 1, 2012, and December 31, 2019. Under a uniform perioperative protocol, the patients who had surgery from January 1, 2012, to December 31, 2014, received irrigating infusion fluid containing balanced salt solution (BSS) only (group 1), and those from January 1, 2015, to December 31, 2019, received BSS with cefuroxime (1500 μg/mL) during surgery (group 2). All eyes were evaluated postoperatively, and the eyes suspected to have endophthalmitis were assessed and treated by a consultation team. The rates of postoperative endophthalmitis in these two groups were calculated. Results A total of 61,299 eyes were included over the eight years. Among these eyes, 11 in group 1 (0.07% of 15,948 eyes) and 5 in group 2 (0.01% of 45,351 eyes) developed endophthalmitis, and the difference was significant (P < 0.01). Five among 16 patients (31.25%) with endophthalmitis were positive in bacterial culture. The positive rate of bacterial culture was not significantly different between group 1 (4/11) and group 2 (1/5) (P > 0.05). No adverse events related to the irrigation of cefuroxime were found. Conclusion Intraoperative cefuroxime irrigation (1500 μg/mL) could decrease the rate of postoperative endophthalmitis after phacoemulsification by 7-fold. This study provides evidence that intraoperative irrigation with cefuroxime is effective as an antibiotic prophylaxis for endophthalmitis.

Microbiological Isolates and Antibiotic Susceptibilities in Cases of Posttraumatic Endophthalmitis: A 15-Year Review. J Ophthalmol 2020; 2020:5053923. [PMID: 32411430 PMCID: PMC7210529 DOI: 10.1155/2020/5053923] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 11/15/2019] [Accepted: 12/07/2019] [Indexed: 11/29/2022] Open
Abstract
Purpose The objective of this study was to evaluate the microbiological spectrum and antibiotic susceptibilities of isolates in posttraumatic endophthalmitis over a 15-year period. Methods A retrospective study of 3,163 posttraumatic endophthalmitis cases was conducted between July 2004 and July 2019. The outcome measures included the microbiological spectrum and antibiotic susceptibilities. Chi-squared tests were conducted to detect trends in changes in antibiotic sensitivity over the 15-year period. P values of <0.05 were considered statistically significant. Results Of the 3,163 cases of posttraumatic endophthalmitis, 1,003 culture-positive isolates were identified. Among these, there were 848 (84.5%) Gram-positive isolates, 109 (10.9%) Gram-negative isolates, and 46 (4.6%) fungal isolates. The most common isolates were Staphylococcal species. There was a significant increase in the percentage of fungal isolates over the 15-year period (P=0.02). Gram-positive organisms showed the greatest level of susceptibility to vancomycin (99.6%). The susceptibilities of the 109 Gram-negative isolated organisms were as follows: levofloxacin (95.8%), meropenem (95.7%), ciprofloxacin (93.5%), tobramycin (90.8%), imipenem (88.9%), trimethoprim-sulfamethoxazole (TMP-SMX) (87.7%), ertapenem (80%), and ceftazidime (79.1%). The susceptibility of Gram-positive organisms to several antibiotics, including levofloxacin (P=0.004), ciprofloxacin (P < 0.001), and chloramphenicol (P=0.001) decreased over time, whereas the susceptibility to TMP-SMX increased over time (P < 0.001). The susceptibility of Gram-negative bacilli to ceftazidime decreased over time (P=0.03). Conclusions Over the 15-year study period, most isolates were Gram-positive cocci, especially coagulase-negative staphylococci (CNS). Vancomycin seemed to be the most effective antibiotic for Gram-positive bacteria. Gram-negative bacteria appeared to be most susceptible to fluoroquinolones. A number of antibiotics showed an increasing trend of microbial resistance.

Commonly used intracameral antibiotics for endophthalmitis prophylaxis: A literature review. Surv Ophthalmol 2020; 66:98-108.

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
Purpose: To compare the incidence of pseudophakic cystoid macular oedema (CME) in patients who receive intracameral cephalosporin versus intracameral vancomycin during cataract surgery.Methods: A retrospective chart review was conducted on subjects with the diagnosis of CME between January 1 2010 and July 31 2017. Inclusion criterion was the documentation of CME after cataract extraction. Exclusion criteria were intraoperative complication, prior history of macular oedema, epiretinal membrane, uveitis, other pre-existing retinal pathology, or other post-operative pathology including other ocular surgery in the post-operative period.Results: The final analysis included 89 eyes with optical coherence tomography (OCT) proven CME. The incidence of pseudophakic CME in our population of 10,165 cataract surgeries after applying the above-stated exclusion criteria was 0.88%. The incidence of pseudophakic CME in subjects who received intracameral cephalosporin was 0.87% (mean age in years 69 ± 11; 31 male [39%], 48 female [61%]). The incidence of pseudophakic CME in subjects who received intracameral vancomycin was 0.96% (mean age in years 66 ± 13; 4 male [40%], 6 female [60%]). Pearson's chi-square test demonstrated no significant difference between these groups (p = 0.7705).Conclusions: There was no statistical difference in the incidence of pseudophakic CME in subjects who received intracameral cephalosporin versus intracameral vancomycin during cataract surgery.
