Abstract

Abstract : Purpose: To compare the incidence of postoperative endophthalmitis before and after the implementation of a preoperative surgical site preparation protocol for cataract surgery. Design: Retrospective cohort study. Methods: Records of patients with postoperative endophthalmitis between January 2006 and August 2013 were reviewed. A revised protocol implemented after January 2009 included the addition of preoperative 0.3% topical tobramycin, 10% povidone-iodine for cleansing, and using a disposable sterile drape. The incidence, microbiological profile, and outcomes of these cases were analyzed. Results: The incidence of preprotocol endophthalmitis was significantly higher than in the postprotocol period ( P = 0.018). More patients in the preprotocol group grew Pseudomonas aeruginosa and Streptococcus pneumoniae as compared with those in the postprotocol group ( P = 0.014). A smaller number of patients attained a poor visual outcome after the implementation of the revised protocol ( P = 0.035). Conclusions: In our study, the addition of antibiotic eye drops before cataract surgery and perioperative cleansing with 10% povidone-iodine were effective means to reduce the incidence of postoperative endophthalmitis.
