Comparison of Efficacy between Non-Steroidal Anti-Inflammatory Drugs and Anti-Vascular Endothelial Growth Factor in Preventing Macular Edema after Cataract Surgery in Diabetic Patients

Abstract

(1) Background: There is no consensus regarding the optimal strategy to prevent macular edema after cataract surgery in diabetic patients. The purpose of study is to compare the efficacy of topical nonsteroidal anti-inflammatory agents (NSAIDs) and intravitreal injections of anti-VEGFs for the prevention of macular edema after cataract surgery in diabetic patients without pre-existing macular edema. (2) Methods: A literature search of the MEDLINE, PUBMED, and EMBASE databases was conducted in July 2021. Studies involving either topical NSAIDs or intravitreal injections of anti-VEGF arms that reported either the occurrence of macular edema or changes in best corrected visual acuity (BCVA) were included. Weighted mean differences and risk ratios were calculated along with 95% confidence intervals. (3) Results: Intravitreal injection of anti-VEGFs provided short-term structural protection for one month in patients receiving cataract surgery, but the protective effect ceased to exist after three months. The structural protection of topical NSAIDs, however, can last for at least three months. Meanwhile, neither anti-VEGFs nor NSAIDs provided significant visual improvement. (4) Conclusions: Our study suggested that topical NSAIDs eye drops is an effective prevention strategy for macular edema after cataract surgery in diabetic patients.
