Abstract

Abstract : Purpose : To compare the development of posterior capsule opacification (PCO) and neodymium:YAG (Nd:YAG) capsulotomy rates between 2 microincision intraocular lenses (IOLs) 4 years after surgery. Setting : Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. Design : Prospective randomized clinical trial. Methods : Patients randomly received a Y‐60H 3‐piece hydrophobic IOL (hydrophobic group) in 1 eye and an MI60 1‐piece hydrophilic IOL (hydrophilic group) in the contralateral eye during simultaneous bilateral cataract surgery. Eyes were examined 1 week, 20 months, and 4 years postoperatively. Digital retroilluminated images of each eye were evaluated using Automated Quantification of After‐Cataract software. The Nd:YAG laser capsulotomy rate was recorded. Results : Sixty patients were enrolled. Objective PCO was significantly higher in the hydrophobic group than in the hydrophilic group before capsulotomy 2 years after cataract surgery (mean score 2.1 ± 1.8 (SD) versus 1.2 ± 1.4) ( P =.031). At the 4‐year follow‐up, the hydrophobic group had a statistically significantly higher Nd:YAG rate than the hydrophilic group (77% versus 50%) ( P =.012). Conclusion : Comparison of 2 microincision IOLs indicated a statistically significant difference in PCO and Nd:YAG capsulotomy rates, with very high Nd:YAG rates 4 years after surgery.
