          Abstract

          We conducted a cohort study to evaluate post-cataract surgery endophthalmitis rates in relation to prophylactic intracameral moxifloxacin administration. A total of 2332 patients (2674 eyes) who underwent phacoemulsification by a single surgeon from January 2007 through December 2012 were included in the study. A total of 1056 eyes did not receive intracameral prophylactic moxifloxacin and the antibiotic was injected in 1618 eyes. The incidence of presumed postoperative endophthalmitis in the 2 groups was calculated. The rate of presumed infectious endophthalmitis after cataract surgery between January 2007 and June 2009 (without intracameral moxifloxacin) was 0.094%. The rate in the second period, from July 2009 to December 2012 (with prophylactic intracameral moxifloxacin), was 0%. In our patients, a decline in the incidence of presumed infectious postoperative endophthalmitis appeared to be associated with the application of intracameral moxifloxacin.

          Prophylaxis of postoperative endophthalmitis following cataract surgery: results of the ESCRS multicenter study and identification of risk factors.

          To identify risk factors and describe the effects of antibiotic prophylaxis on the incidence of postoperative endophthalmitis after cataract surgery based on analysis of the findings of the European Society of Cataract & Refractive Surgeons (ESCRS) multicenter study. Twenty-four ophthalmology units in Austria, Belgium, Germany, Italy, Poland, Portugal, Spain, Turkey, and the United Kingdom. A prospective randomized partially masked multicenter cataract surgery study recruited 16 603 patients. The study was based on a 2 x 2 factorial design, with intracameral cefuroxime and topical perioperative levofloxacin factors resulting in 4 treatment groups. The comparison of case and non-case data was performed using multivariable logistic regression analyses. Odds ratios (ORs) associated with treatment effects and other risk factors were estimated. Twenty-nine patients presented with endophthalmitis, of whom 20 were classified as having proven infective endophthalmitis. The absence of an intracameral cefuroxime prophylactic regimen at 1 mg in 0.1 mL normal saline was associated with a 4.92-fold increase (95% confidence interval [CI], 1.87-12.9) in the risk for total postoperative endophthalmitis. In addition, the use of clear corneal incisions (CCIs) compared to scleral tunnels was associated with a 5.88-fold increase (95% CI, 1.34-25.9) in risk and the use of silicone intraocular lens (IOL) optic material compared to acrylic with a 3.13-fold increase (95% CI, 1.47-6.67). The presence of surgical complications increased the risk for total endophthalmitis 4.95-fold (95% CI, 1.68-14.6), and more experienced surgeons were more likely to be associated with endophthalmitis cases. When considering only proven infective endophthalmitis cases, the absence of cefuroxime and the use of silicone IOL optic material were significantly associated with an increased risk, and there was evidence that men were more predisposed to infection (OR, 2.70; 95% CI, 1.07-6.8). Use of intracameral cefuroxime at the end of surgery reduced the occurrence of postoperative endophthalmitis. Additional risk factors associated with endophthalmitis after cataract surgery included CCIs and the use of silicone IOLs.

            Acute endophthalmitis following cataract surgery: a systematic review of the literature.

            To determine the reported incidence of acute endophthalmitis following cataract extraction over time and to explore possible contributing factors, such as type of cataract incision. A systematic review of English-language articles was conducted by performing a broad search of PubMed from 1963 through March 2003 using such terms as cataract extraction, endophthalmitis, and postoperative complication. Additional studies were identified from bibliographies of relevant articles and published proceedings. Surgical approach was recorded, when available. Pooled incidence rates and relative risks of developing endophthalmitis using different incision techniques were assessed. From 4916 unique, potentially relevant citations, 215 studies that addressed endophthalmitis and met the selection criteria were analyzed. A total of 3 140 650 cataract extractions were pooled resulting in an overall rate of 0.128% of postcataract endophthalmitis. However, the incidence of acute endophthalmitis changed over time, with a significant increase since 2000 compared with previous decades (relative risk, 2.44 [95% confidence interval, 2.27-2.61]). The rate of endophthalmitis was 0.265% in the 2000-2003 period, 0.087% in the 1990s, 0.158% in the 1980s, and 0.327% during the 1970s. Furthermore, an upward trend in rates after 1992 was noted, compared with 1991 and prior. Incision type appeared to significantly influence risk, as endophthalmitis following clear corneal cataract extraction during the 1992-2003 period was 0.189% compared with 0.074% (relative risk, 2.55 [95% confidence interval, 1.75-3.71]) for scleral incision and 0.062% (relative risk, 3.06 [95% confidence interval, 2.48-3.76]) for limbal incision. This systematic review indicates that the incidence of endophthalmitis associated with cataract extraction has increased over the last decade. This upward trend in endophthalmitis frequency coincides temporally with the development of sutureless clear corneal incisions.

              Six-year incidence of endophthalmitis after cataract surgery: Swedish national study.

              To report the nationwide incidence and risk factors for endophthalmitis after cataract surgery in Sweden. Swedish National Cataract Register containing reports on cataract operations from all Swedish ophthalmic surgical units. Prospective epidemiologic study. Endophthalmitis case reports were collected from 2005 through 2010. Case and control parameters pertaining to patient characteristics and surgical technique were generated from the database. In addition, information from annual surveys regarding the topical prophylactic protocol was analyzed. The reports showed 135 endophthalmitis cases in 464,996 operations, equaling an incidence of 0.029%. Patient age over 85 years, perioperative communication with the vitreous and, above all, nonuse of intracameral cefuroxime showed a statistically significant association with endophthalmitis in the logistic regression. Short-term topical antibiotics given as add-on prophylaxis to the intracameral regimen before, after, or before and after the operation did not confer a clear-cut benefit. Groups with topical treatment were small, comprising 14% of the sample. The incidence of endophthalmitis after cataract surgery in Sweden is declining, which appears to be explained by a fall in the frequency of major risk factors. Operating earlier in the cataract course, avoiding capsule breakage, and giving intracameral antibiotics universally should further reduce the endophthalmitis rate. Copyright © 2013 ASCRS and ESCRS.
