PURPOSE: To evaluate the effectiveness of a nonsteroidal antiinflammatory drug (NSAID) on pseudophakic cystoid macular edema (CME) and determine the efficacy when used preoperatively and after uneventful phacoemulsification surgery. SETTING: Department of Ophthalmology, Kocatepe University, School of Medicine, Afyonkarahisar, Turkey. METHODS: One hundred seventy-nine eyes of 189 patients having uneventful phacoemulsification surgery were enrolled in the study. After surgery, all patients used topical steroids and antibiotics 4 times daily. Sixty-one eyes, chosen randomly, received a topical NSAID (indomethacin) 4 times daily for 3 days preoperatively and 1 month postoperatively. Sixty eyes received topical indomethacin 4 times daily for 1 month postoperatively. Fifty-eight eyes served as a control group and received only topical steroids and antibiotics. At the third postoperative month, visual acuity, fluorescein angiograms, and macular thresholds were evaluated. Statistical analysis was by chi-square and 1-way analysis of variance tests. RESULTS: Cystoid macular edema was not seen in the group receiving indomethacin preoperatively and postoperatively. The incidence of angiographic CME was 15.0% in the group receiving postoperative indomethacin and 32.8% in the control group (P<.001). Mean sensitivity in the macular threshold test did not show a significant change between groups (P = .83). Postoperative visual acuity was significantly higher in the group receiving preoperative indomethacin (P<.001). CONCLUSION: Nonsteroidal antiinflammatory drugs decreased the incidence of CME, and their efficacy increased when begun preoperatively.
