AIM: To evaluate the effect of topical preoperative nepafenac 0.1% treatment on postoperative macular edema using optical coherence tomography (OCT) after uncomplicated cataract surgery. METHODS: Ninety eyes of 90 patients without any risk factors were included in the study. The patients were assigned to three groups: group 1, treated with topical prednisolone acetate 1%; group 2, treated with topical nepafenac 0.1% in addition to prednisolone acetate (1%); and group 3, those who started receiving nepafenac 0.1% treatment 3d prior to surgery and continued the treatment postoperatively in addition to prednisolone acetate (1%). Central retinal thickness (CRT) and macular volume values were recorded using OCT at weeks 3 and 6. RESULTS: The increases in macular volume in the central 1 mm area after 3 and 6wk were significantly lower in patients who used prophylactic topical nepafenac preoperatively (group 3) compared with those in group 1 (P=0.028 and 0.008, respectively). No significant differences in the increase in macular volume and CRT were noted between groups 2 and 3 (P>0.05). In group 1, the increases in macular volume in the central 3 mm area at weeks 3 and 6 were significantly higher than that in group 2 and 3 (3rd week, P=0.004; 6th week, P=0.005). CONCLUSION: Nepafenac 0.1% treatment in addition to topical steroids after uncomplicated cataract surgery reduce the increase in macular volume in the early postoperative period.
