Efficacy of Nonsteroidal Anti-Inflammatory Drugs for the Prevention of Cystoid Macular Edema Following Cataract Phacoemulsification
Přehled studie
Postavení
Detailní popis
Cystoid macular edema remains one of the most important causes of suboptimal visual outcomes after cataract surgery. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to reduce postoperative inflammation and the risk of macular thickening; however, the optimal NSAID regimen remains uncertain.
This prospective randomized clinical study was designed to compare the effectiveness of different postoperative NSAID regimens following uncomplicated phacoemulsification cataract surgery. Eligible patients scheduled for elective cataract surgery were randomly assigned to one of four treatment groups using a simple dice-based randomization procedure. Participants underwent ophthalmic examinations before surgery and at 6 and 12 weeks after surgery.
The primary objective was to evaluate changes in central subfield thickness (CST) measured by spectral-domain optical coherence tomography (OCT). Secondary assessments included best-corrected distance visual acuity, refraction, and intraocular pressure. All participants received standard perioperative care, and postoperative treatment was administered according to the assigned study regimen.
The study was approved by the Bioethics Committee of the Pomeranian Medical University in Szczecin, and all participants provided written informed consent before enrollment.
