目的：评价3年内2种疏水性丙烯酸单片锐边人工晶状体（IOL）之间后囊膜混浊（PCO）发生率以及视觉和光学性能的差异。单位：维也纳医科大学眼科，维也纳，奥地利。设计图：前瞻性随机病例系列：方法：双侧白内障患者前瞻性随机接受Eyecee One IOL（IOL A）或Acrysof SN 6 OWF IOL（IOL B），并随访36个月。测量矫正远视力（CDVA）、IOL偏心和倾斜。通过分析标准化的后照明图像，对PCO进行定量分析。在所有随访访视时，两种IOL的PCO发生率均较低。术后3年，IOL A的中位客观PCO评分为1.4（范围0 - 5.6），IOL B为1.5（范围0 - 5.0）（P = 0.67）。术后3年钕：YAG（Nd：YAG）晶状体囊切开术率分别为16.4%和6.0%（P = 0.06）。视力和对比敏感度的结果也是可比的，在所有后续vision.Conclusions：这两个IOL显示良好的囊袋性能和低PCO率手术后3年。两种IOL在视力、对比敏感度、偏心和倾斜、PCO评分、裂隙灯检查和Nd：YAG晶状体囊切开术率方面的结果也相当。(C)2017 ASCRS和ESCRS
Purpose: To evaluate the differences in the incidence of posterior capsule opacification (PCO) and visual and optical performance between 2 hydrophobic acrylic single-piece sharp-edged intraocular lenses (IOLs) over 3 years.Setting: Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. Design: Prospective randomized case series.Methods: Patients with bilateral cataract were prospectively randomized to receive an Eyecee One IOL (IOL A) or an Acrysof SN6OWF IOL (IOL B) and were followed for 36 months. The corrected distance visual acuity (CDVA) and IOL decentration and tilt were measured. The PCO was quantified by analysis of standardized retroillumination images.Results: The study comprised 160 eyes of 80 patients. The PCO incidence was low for both IOLs at all follow-up visits. Three years postoperatively, the median objective PCO score was 1.4 (range 0 to 5.6) for IOL A and 1.5 (range 0 to 5.0) for IOL B (P = .67). The neodymium:YAG (Nd:YAG) capsulotomy rate 3 years after surgery was 16.4% and 6.0% (P = .06), respectively. Visual acuity and contrast sensitivity outcomes were also comparable at all follow-up visits.Conclusions: Both IOLs showed good capsular bag performance and low PCO rates 3 years after surgery. Both IOLs also showed comparable results for visual acuity, contrast sensitivity, decentration and tilt, PCO score, slitlamp examination, and Nd:YAG capsulotomy rates. (C) 2017 ASCRS and ESCRS
