Efficacy of intracameral antibiotics following manual small incision cataract surgery in reducing the rates of endophthalmitis: A meta-analysis.

Abstract

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. 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. 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. 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.
