Efficacy of addition of nepafenac 0.1% to steroid eye drops in prevention of post-phaco macular edema in high-risk eyes

Abstract

Purpose:

To compare the efficacy of addition of nonsteroidal anti-inflammatory eye drops to steroidal eye drops with that of using postoperative steroidal anti-inflammatory eye drops alone in prevention of macular edema in high-risk patients.

Setting:

Cairo University Hospital.

Design:

This study was comparative prospective interventional randomized study.

Methods:

This study included 100 cataractous eyes divided into five subgroups: 20 eyes of diabetic patients, 20 uveitic eyes, 20 traumatic cataracts, 20 glaucomatous eyes on topical prostaglandin analogs, and 20 eyes with posterior capsular rupture during phacoemulsification. Each subgroup of 20 was randomized between two groups of 10 eyes, group A received postoperative topical steroids alone and group B received both steroidal and nonsteroidal anti-inflammatory eye drops.

Results:

There was significant increase in postoperative central foveal thickness as compared to preoperative values in both groups (60.9 ± 87.95 µ in group A and 25.52 ± 57.26 µ in group B) that was significantly more in group A (P value 0.016). There was significant difference in postoperative macular thickness between both groups (280.1 ± 86.0 µ and 246.80 ± 57.73 µ, respectively, in groups A and B) (P value = 0.012). There was no statistically significant difference between both groups in preoperative and postoperative corrected distance visual acuity and intraocular pressure.

Conclusion:

Addition of topical nepafenac eye drops to topical steroid drops significantly reduced the amount of pseudophakic macular edema after cataract surgery in high-risk eyes.
