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
This study assesses the effect of 17β-estradiol on oxidative damage and NOTCH1 levels in cataract rats. 45 SD rats, aged 8–12 weeks old and weighted 225–312 g were assigned into healthy group, cataract group, and treatment group with n = 15 in each group
followed by analysis of the pathological morphology of rat lens by HE staining, cell apoptosis by flow cytometry, and the degree of turbidity under a microscope. Meanwhile, MDA and SOD levels were measured and NOTCH1, p53 and BAX expressions was detected by PT-PCR. The Healthy group rats showed
complete and orderly lens structure, whereas, the cataract group showed disorganized and distributed loosely lens, with the formation of vacuoles and the rupture and degradation of fibrocells. In the treatment group, the lens epithelial cells were orderly and evenly distributed, and the vacuoles
were significantly reduced. The apoptotic rate of lens epithelial cells in healthy group (1.79±0.11)% was significantly lower than that in cataract group (15.22±1.17)% (P < 0.05), which showed significantly higher apoptotic rate than treatment group (6.31±1.12)%
(P < 0.05). The degree of eye turbidity was increased in cataract group and reduced in treatment group compared with that in healthy group (P < 0.05). In addition, cataract group showed significantly reduced SOD and increased MDA level groups along with upregulated Notch1,
p53 and Bax (P < 0.05). However, treatment group showed significantly increased SOD, decreased MDA and downregulated Notch1, p53 and Bax. In conclusion, 17β-estradiol reduces the apoptosis rate of lens epithelial cells in cataract rats by reducing NOTCH1 level, thereby
enhancing the ability to resist oxidative damage.

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
Moxifloxacin (MOX) suppresses cell movement in human corneal fibroblasts (HCFs). Zonula occludens-1 (ZO-1) is localized to the leading edge of migrating HCFs. This study explored the role of ZO-1 in MOX-suppressed cell migration in HCFs. A single-cell trajectory analysis revealed that MOX negatively regulated the migratory properties of HCFs including migration distance, migration velocity, and directionality (P < 0.001, P < 0.001, and P = 0.018, respectively). MOX increased endogenous ZO-1 in HCFs in a concentration-dependent manner (P = 0.083, P = 0.005, and P = 0.001 at 10, 50, and 100 μg/ml, respectively), but decreased the phosphorylation of endogenous ZO-1 at serines, threonines, and tyrosines. In contrast, MOX did not alter the expression of protein kinase C epsilon (PKCε), Rac-1, Cdc42, and MRCKβ. However, MOX did also reduce the phosphorylation level of PKCε at serines and threonines (P < 0.001 at 100 μg/ml). In addition, MOX increased the phosphorylation level of Rac-1 in a concentration-dependent manner (P < 0.001 at 100 μg/ml). Compared with the mock cells, the directionality of cell movement increased significantly in ZO-1-expressing HCFs (P = 0.012) and decreased significantly in ZO-1-silenced HCFs (P = 0.002). The directionality did not change significantly in Rac-1-silenced HCFs. ZO-1-expressing HCFs moved faster than mock cells. PKCε, Cdc42, Rac-1, and phosphorylated Rac-1 were decreased in ZO-1-overexpressing HCFs, but increased in ZO-1-silenced HCFs. Finally, silencing ZO-1 blocked MOX hyperactivation of Rac-1. These suggest that MOX might trigger random migration in human corneal stromal cells through PKCε-modulated ZO-1 inactivation and Rac-1 hyperactivation.

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
Objective Intended to investigate the epidemiological characteristics, risk factors and incidence trend of endophthalmitis after cataract surgery in recent 12 years. Methods A retrospective study was conducted on the patients who underwent cataract surgery in Qingdao Eye Hospital from January 1, 2008, to December 31, 2019, including age, sex, history of diabetes, intraoperative operation and complications. In addition, the related risk factors and incidence trend of acute infective endophthalmitis were analyzed. The incidence of endophthalmitis and its related factors were analyzed by univariate and multivariate logistic regression analysis. Results A total of 55,612 cases of cataract surgery were performed in our hospital in 12 years, and 42 cases of acute infective endophthalmitis occurred (the incidence rate was 0.076%). The average occurrence time was 10.57 days ± 11.17, with eye pain as the main complaint and anterior chamber fibrin exudation as the main clinical manifestation. In addition, there were eight cases of anterior chamber hypopyon and 18 cases of vitreous reaction, the results of anterior aqueous humor or vitreous fluid culture in 10 patients were positive. Univariate analysis showed that intraoperative rupture of posterior capsule, non-use of antibiotics and non-use of behind-the-lens washout were the risk factors of infectious endophthalmitis after cataract surgery (P=0.032, P=0.000, P=0.000). Besides, multivariate logistic regression analysis showed that intraoperative rupture of posterior capsule was the main risk factor. Conclusion The occurrence of endophthalmitis after cataract surgery is mainly related to intraoperative rupture of posterior capsule, absence of antibiotics and behind-the-lens washout. In addition, the incidence of endophthalmitis after cataract surgery decreased during the past 12 years.

Abstract
PURPOSE To report toxic posterior segment syndrome after dropless cataract surgery using locally compounded triamcinolone-moxifloxacin. METHODS A retrospective case review of 7 patients presenting with a decrease in visual acuity after dropless cataract surgery. RESULTS All patients experienced significant reductions in best-corrected visual acuity of the postoperative eye ranging from 20/40 to count finger at 4 feet (average best-corrected visual acuity 20/220) immediately after surgery. The presenting symptoms included flashes, floaters, photophobia, glare, halos, visual distortions, and problems assessing colors. In three cases, foveal retinal pigment epithelium changes were noted on dilated fundus exam (DFE). Ellipsoid zone loss was noted on ocular coherence tomography in five of the seven affected eyes. Electrophysiology testing in five of the seven affected eyes demonstrated large decreases in full-field electroretinogram amplitude, oscillatory potentials, multifocal electroretinogram, and visual evoked potential, along with a negative electroretinogram. One patient was treated with a dexamethasone implant, but no improvement in visual acuity was noted. CONCLUSION This is the first case series of toxic posterior segment syndrome occurring secondary to intracameral compounded triamcinolone-moxifloxacin in dropless cataract surgery. The FDA has attributed the toxicity to abnormally high levels of the binding agent poloxamer 407 in the compounded medication. Clinicians should be aware of this phenomenon and exhibit caution when using compounded medications.

Abstract
Purpose: The intraocular lens (IOL) is a common, yet important, implantable device used in treatment of cataract in clinics. However, the unexpected adhesion of postoperative residual lens epithelial cells (LECs) often causes serious complications, such as posterior capsular opacification (PCO), which lead to vision loss again. In this investigation, a poly(sulfobetaine methacrylate) (PSBMA) brush coating was fabricated on an IOL to generate a hydrophilic surface coating on the IOL for enhanced cell adhesion resistance so as to decrease PCO incidence. Methods: The PSBMA brush coating on the IOL surface was fabricated using surface-initiated reversible addition-fragmentation chain transfer polymerization. X-ray photoelectron spectroscopy (XPS) was used to demonstrate the surface coating preparation. The water contact angle (WCA) measurement was used to test surface hydrophilicity. In vitro LEC culture was use to evaluate the cell behavior on the IOL material surfaces, with or without PSBMA coating modification. Finally, animal cataract surgeries were carried out to evaluate in vivo biocompatibilities and anti-PCO effects. Results: The XPS and WCA measurements illustrate successful surface modification and good surface hydrophilicity. The in vitro cell culture results show that the hydrophilic PSBMA polymer brush coating evidently decreases adhesion and proliferation of LECs. Results of the in vivo cataract surgery with intraocular implantation show that PSBMA modification on the IOL surface does not induce side effects in nearby tissues, whereas posterior capsular hyperplasia can be evidently reduced. Conclusion: The PSBMA brush surface-modified IOL has good in vivo biocompatibility and it can effectively reduce the incidence of postoperative PCO.

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 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 OF REVIEW Routine prophylaxis for adverse events following cataract surgery is evolving. Prior reliance on topical eyedrop instillation by patients is giving way to surgeon directed injections at the time of cataract surgery. The benefit of this new approach is assured delivery of drugs in standardized doses which should optimize the healing process and reduce the incidence of untoward events with higher confidence. RECENT FINDINGS Adoption rates of intracameral antibiotic injection amongst European and American cataract surgeons is increasing. Techniques to inject periocular corticosteroid for routine inflammation prophylaxis are also in development. In combination with intraoperative pharmacologic dilation, a drop-free modality can be achieved. SUMMARY Intraoperative injections offer the patient and surgeon assured drug delivery and hold promise to avoid the pitfalls of patient adherence, incorrect topical instillation, and topical drop-associated corneal issues.

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
The current evidence of postoperative endophthalmitis management in three important components of care-infection control, inflammation control, and prevention was reviewed, and their current relevance and application in an Indian context were evaluated. The publications from India indicated that Gram-negative bacterial and filamentous fungal infections are relatively higher. There are increasing instances of resistance to ceftazidime by Gram-negative microorganisms. Intravitreal dexamethasone limits inflammation in bacterial endophthalmitis when given together with the intravitreal antibiotics. Intracameral antibiotic could reduce postcataract surgery infection at least in less rigorous surgical environment. Systematic collection of data and periodic evaluation of the current practice against the new evidence are necessary to prevent or treat postcataract surgery endophthalmitis.

Abstract
Various protocols are being followed for endophthalmitis prophylaxis in cataract surgery, and this subject continues to be a matter of debate. We summarize the most recent evidence-based studies on this topic with additional stress on intracameral (IC) antibiotic prophylaxis. Here, we discuss several large, international clinical studies which discuss the efficacy, adoption, safety, cost, and newer trends in antibiotic prophylaxis. Majority of these studies report a significant reduction in endophthalmitis rates with IC antibiotic prophylaxis. Efficacy data have been reported for IC cefuroxime, vancomycin, and moxifloxacin. Surgeons are now looking for alternatives to vancomycin for IC prophylaxis because of its association with the rare but sight-threatening complication of hemorrhagic occlusive retinal vasculitis. A recent large clinical study shows convincing efficacy with IC moxifloxacin prophylaxis. Two large studies have also reported significant endophthalmitis reduction following use of IC antibiotic prophylaxis, in eyes with posterior capsule tear which are at highest risk for infection. Except for one randomized controlled trial, there is a lack of prospective data on this subject; however, considering the complexity of performing such studies, surgeons have to rely on the mounting evidence from other recent big data studies. Availability of approved intraocular antibiotic formulations will see a much higher adoption in the future.

Abstract
Endophthalmitis after cataract surgery is a rare but potentially devastating complication. There is great variability in endophthalmitis prophylaxis practice patterns worldwide. Treatment varies globally and is based on the microbiological profile and availability of formulations. Periocular povidone-iodine antisepsis is universally adopted and considered the standard of care in most practices. Perioperative topical antibiotics are also very popular despite the lack of level 1 evidence confirming efficacy. Based on growing observational evidence, routine intracameral antibiotic prophylaxis is increasing, especially where approved commercial intraocular preparations are available. This review updates recent trends and evidence regarding endophthalmitis prophylaxis and the preferred choice of intracameral antibiotics.

Abstract
In 2013, the Danish Health and Medicines Authorities published a National Clinical Guideline on the treatment of age-related cataracts. The guideline provided evidence-based recommendations on the indication for cataract surgery, cataract surgery in patients with age-related macular degeneration, on the use of toric intraocular lenses (IOLs) to correct preoperative corneal astigmatism, the use of intracameral and topical antibiotics to prevent endophthalmitis, choice of anti-inflammatory medication to control postoperative inflammation and prevent cystoid macular oedema, the use of immediate sequential bilateral cataract surgery and on the postoperative check-up of patients. A questionnaire was sent to all members of the Danish Ophthalmological Society before and after publication of the guideline. The responses showed that the guideline had changed practice patterns so that surgeons were more likely to prescribe non-steroidal anti-inflammatory eye drops and to not prescribe topical antibiotic eye drops after the guideline was published. Other parameters, most notably the use of toric IOLs and use of postoperative examinations were more guided by reimbursement standards than by evidence-based medicine. Thus, evidence-based guidelines do change practice patterns unless they are counteracted by the reimbursement system.

Abstract
Cataract surgery is the most commonly performed surgical procedure in many developed countries. Postoperative endophthalmitis is a rare complication with potentially devastating visual outcomes. Currently, there is no global consensus regarding antibiotic prophylaxis in cataract surgery despite growing evidence of the benefits of prophylactic intracameral cefuroxime at the conclusion of surgery. The decision about which antibiotic regimen to use is further complicated in patients reporting penicillin allergy. Historic statistics suggesting crossreactivity of penicillins and cephalosporins have persisted into modern surgery. It is important for ophthalmologists to consider all available antibiotic options and have an up-to-date knowledge of antibiotic crossreactivity when faced with the dilemma of choosing appropriate antibiotic prophylaxis for patients undergoing cataract surgery with a history of penicillin allergy. Each option carries risks, and the choice may have medicolegal implications in the event of an adverse outcome. We assess the options for antibiotic prophylaxis in cataract surgery in the setting of penicillin allergy and provide an algorithm to assist decision-making for individual patients.

Abstract
PURPOSE To compare the postoperative endophthalmitis rate before and after initiation of intracameral (IC) moxifloxacin prophylaxis for both phacoemulsification and sutureless, manual small-incision cataract surgery (M-SICS), as well as in patients with posterior capsular rupture (PCR). DESIGN Retrospective, clinical registry. PARTICIPANTS All cataract surgeries (617 453) performed during the 29-month period from January 2014 to May 2016 at the 10 regional Aravind eye hospitals were included. METHODS The electronic health record data for all study eyes were analyzed. Endophthalmitis rates before and after moxifloxaxin were statistically compared for all eyes and separately for both phacoemulsification and M-SICS, and for the eyes complicated by PCR. MAIN OUTCOME MEASURES The postoperative endophthalmitis rates before and after initiation of IC moxifloxacin prophylaxis. RESULTS Overall, 302 815 eyes did not receive IC moxifloxacin and 314 638 eyes did, and there was a significant decline in the endophthalmitis rate, from 0.07% (214/302 815) to 0.02% (64/314 638) (P < 0.001), with moxifloxacin. For the 194 252 phacoemulsification eyes, the endophthalmitis rate was 0.07% (75/104 894) without IC moxifloxacin prophylaxis, compared with 0.01% (11/89 358) with moxifloxacin (P < 0.001). For the 414 657 M-SICS eyes, the endophthalmitis rate was 0.07% (135/192 149) without IC moxifloxacin prophylaxis, compared with 0.02% (52/222 508) with moxifloxacin (P < 0.001). Approximately half of the 8479 eyes that had PCR received IC moxifloxacin, and half did not. Without IC moxifloxacin, PCR increased the endophthalmitis rate nearly 7-fold to 0.48% (20/4186); IC moxifloxacin reduced the endophthalmitis rate with PCR to 0.21% (9/4293) (P = 0.034). No adverse events were due to IC moxifloxacin. CONCLUSIONS Routine IC moxifloxacin prophylaxis reduced the overall endophthalmitis rate by 3.5-fold (3-fold for M-SICS and nearly 6-fold for phacoemulsification). There was also a statistical benefit for eyes complicated by PCR, and IC antibiotic prophylaxis should be strongly considered for this high-risk population. These conclusions are strengthened by the high volume of cases analyzed at a single hospital network over a comparatively short time frame. Considering the association of hemorrhagic occlusive retinal vasculitis with vancomycin and the commercial unavailability of IC cefuroxime in many countries, moxifloxacin appears to be an effective option for surgeons electing IC antibiotic prophylaxis.

Abstract
Purpose of review To evaluate relevant clinical outcomes following a transzonular intravitreal injection of a compounded triamcinolone–moxifloxacin–vancomycin (TMV) formulation for postoperative prophylaxis after cataract surgery in a retrospective review of medical records from a private practice, single-specialty ambulatory center in New Jersey, USA. Recent findings The analysis included 1541 cases from 922 patients who underwent cataract surgery with an intravitreal injection of TMV from November 2013 to December 2014. Cataract surgery was performed by a standard clear corneal phacoemulsification technique. Transzonular injection was used to deliver TMV directly into the anterior vitreous after implantation of an intraocular lens. Summary There were no major intraoperative complications associated with the transzonular injection technique. There were no cases of postoperative endophthalmitis. Nearly 92% of cases (n = 1413/1541) did not require supplemental medication after surgery. The rate of breakthrough inflammation at Days 14–21 was 9.2% (n = 132/1429). The rate of visually significant postoperative cystoid macular edema was 2.0% (n = 28/1429). The rate of clinically significant postoperative intraocular pressure increase was low: 0.9% (n = 13/1425) of cases had an at least 10 mmHg increase at Days 14–21 or 90. Four of these cases had intraocular pressure at least 30 mmHg. The rates of infection and inflammation reported in this retrospective review of a transzonular injection of TMV for prophylaxis after cataract surgery appear similar to reported rates with alternative prophylactic therapies such as topical drops. The transzonular injection of TMV may have advantages in terms of patient compliance.

Abstract
PURPOSE OF REVIEW After publication of the results of the European Society of Cataract and Refractive Surgery (ESCRS) study, there is a lot of enthusiasm for using intracameral antibiotics for the prevention of postcataract endophthalmitis. However, despite level 1 evidence, the practice has not been adopted universally. The aim of this review is to present a summary of the articles published in the last 18 months on this topic. RECENT FINDINGS The published literature highlights that the incidence rate of endophthalmitis declined after 2007. Simultaneously, there is a rising trend for using intracameral injection of antibiotics at the conclusion of cataract surgery. Although various drugs have been used for this purpose, nearly all provide comparable protection. Industry has started manufacturing formulations for commercial availability of intracameral injection. Innovations are also ongoing to use intraocular lens for drug delivery and developing other intraocular drug delivery devices. SUMMARY Endophthalmitis prevention is at an interesting crossroad. Although there is hesitation the intracameral injection of antibiotics is increasingly being adopted by physicians, which is likely to grow further with commercial availability of formulations. However, it will be important to be cautious and report all adverse reactions associated with this practice.
