RESUMO
PURPOSE: To determine whether an intracameral injection of cefuroxime at the end of cataract surgery decreases the incidence of postoperative endophthalmitis. SETTING: Dupuytren Hospital, Ophthalmology Department, Limoges, France. DESIGN: Clinical trials. METHODS: Patients having cataract surgery between April 2003 and June 2008 were included in a survey of operative-site infection. Intracameral cefuroxime injections started in June 2006. Preoperative data (beta-lactam allergy, a history of endophthalmitis, age, sex), intraoperative data (use of trypan blue, use of capsular ring or iris retractors, surgical time, senior or junior surgeon, corticosteroid injection, iris retractors), and the incidence of postoperative infections at 8 days and 1 month were prospectively collected. RESULTS: During the inclusion period, 5115 patients had cataract surgery; 2289 received cefuroxime and 2826 did not. The incidence of endophthalmitis was 35 (1.238%) of 2826 patients without intracameral cefuroxime and 1 (0.044%) of 2289 patients with intracameral cefuroxime; the difference was statistically significant (P<.0001). No intraoperative factor was significantly associated with postoperative infection. No allergic reaction was reported. CONCLUSION: Intracameral cefuroxime injection at the end of cataract surgery was safe and significantly decreased the incidence of endophthalmitis.
