PURPOSE: To evaluate the incidence of pseudophakic cystoid macular edema (PCMO) in patients treated withcorticosteroids alone or in combination with bromfenac or nepafenac eyedropsafter uneventful cataract surgery. MATERIALS AND METHODS: Prospective, randomized, open-label, placebo-controlled clinical trial. Patients who underwent routine cataract surgery with intraocular lens (IOL) implant were randomly divided into three groups receiving either bromfenac or nepafenac in association with dexamethasone or dexamethasone alone (control group) postoperatively. Best-corrected visual acuity (BCVA) measurement, slit lamp and fundus examination and optical coherence tomography (OCT) were performed preoperatively, 1 and 5 weeks after surgery. Primary outcome was defined as patients (%) in whom macular edema developed within 5 weeks after cataract surgery; secondary end points were patients (%) with BCVA improvement from pre-op through 5 weeks after surgery and corneal toxicity. RESULTS: A total of 144 patients completed the study, 48 for each group. In all groups, mean central subfield thickness at OCT increased significantly 5 weeks after surgery (p < 0.01). However, at this time point, four patients (8.3%) of the control group and none in nepafenac and bromfenac groups developed PCMO (p = 0.016). Compared with baseline, mean BCVA significantly improved both at 1 and 5 weeks in all groups (p < 0.01). At 1 week, the nepafenac group showed a mean BCVA significantly lower compared with both the control (p = 0.038) and bromfenac group (p = 0.002). CONCLUSIONS: Co-administration of nepafenac or bromfenac and steroids in patients who underwent routine cataract surgery is associated with a lower incidence of PCMO compared with steroid monotherapy.
