Effect of preoperative topical nepafenac 0.1% on inflammatory response after uncomplicated cataract surgery in healthy subjects

Abstract

Purpose: To determine the effect of preoperative topical Nepafenac administration on anterior chamber flare after uneventful cataract surgery in healthy subjects.

Methods: Prospective randomized clinical trial. Seventy-three eyes of 73 healthy patients undergoing routine cataract surgery were randomized to receive (group A) topical nepafenac (1 mg/ml) or not to receive (group B) 1 drop 3 times per day for 3 days before surgery. All eyes received the same postoperative anti-inflammatory therapy. Clinical outcome parameters such as best corrected visual acuity, intraocular pressure, retinal central foveal thickness and aqueous flare were recorded preoperatively, 1, 15, 30 and 60 days after surgery.

Results: Three patients were excluded for poor compliance, and three patients were excluded or developing pseudophakic macular oedema during the follow-up. Both groups were comparable for age, gender, and showed similar BCVA, intraocular pressure and central macular thickness values preoperatively and during the entire follow-up (p > 0.01). Aqueous flare values showed a statistically increase in both groups respect to preoperative values through follow-up evaluations (p < 0.01), while values were significantly lower in group A than in group B 30 days after surgery (p < 0.01).

Conclusion: Preoperative administration of topical Nepafenac reduces the inflammatory response in healthy patients undergoing uncomplicated cataract surgery one month after surgery respect to non-treated group.
