Pak Armed Forces Med J Jan ;71(4):1451-54.

Objective: To assess the efficacy of prophylactic administration of 0.1% nepafenac in the maintenance of trans-operative mydriasis following cataract surgery. Study Design: Quasi-experimental study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi, from Oct 2018 to Mar 2019. Methodology: A total of 70 patients undergoing cataract surgery phacoemulsification were randomly placed in either the control group or the nepafenac group. Nepafenac eye drops were administered as one drop 8 hourly, 3 days before surgery. Control group didn’t receive any medication preoperatively Mydriasis was measured trans-operatively before surgery, after aspiration of the cortex, and then at the end of surgery. Patients of both groups received tobradex 2 weeks post-surgery. Results: Post-surgery statistically significant (0.001) difference was observed in the mean pupil size between the nepafenac group (7.88 ± 0.49) and the control group (6.57 ± 0.92 mm). Conclusion: Use of nepafenac prophylactically was very effective in maintenance of trans-operative mydriasis in cataract surgery.
