目得：目的：比较白内障手术后5 ~ 7年植入2枚疏水性丙烯酸人工晶状体（IOL）后后囊膜混浊（PCO）和闪光情况，评价其对矫正远视力（CDVA）和对比敏感度的影响。患者被随机分配至Acrysof SA 60 AT（单件式IOL组）或Sensar AR 40 e（3件式IOL组），均为锐边设计的疏水性丙烯酸IOL。术后5 - 7年，获得后照明图像，并使用计算机软件评价PCO面积和严重程度（撕囊内受影响的面积和严重程度）。测量了高对比度（100%）和低对比度（2.5%）的CDVA。记录Nd：YAG激光晶状体囊切开率。获得Scheimpflug图像，以评估glistenings，这是在裂隙灯主观分级和量化客观的数字图像分析，使用计算机software.RESULTS：该研究纳入了80例患者。两组之间的PCO无显著差异。三片式人工晶状体组的闪光明显减少（P
PURPOSE: To compare posterior capsule opacification (PCO) and glistenings 5 to 7 years after cataract surgery with implantation of 2 hydrophobic acrylic intraocular lenses (IOLs) and evaluate the effects on corrected distance visual acuity (CDVA) and contrast sensitivity.SETTING: St. Erik Eye Hospital, Stockholm, Sweden.DESIGN: Randomized clinical trial.METHODS: Cataract surgery with standard phacoemulsification was performed in 1 eye of patients. The patients were randomized to an Acrysof SA60AT (1-piece IOL group) or a Sensar AR40e (3-piece IOL group), both hydrophobic acrylic IOLs with a sharp-edged design. Five to 7 years postoperatively, retroillumination images were obtained and the PCO area and severity (area affected within the capsulorhexis and severity) were evaluated using computer software. High-contrast (100%) and low-contrast (2.5%) CDVAs were measured. The neodymium:YAG laser capsulotomy rates were recorded. Scheimpflug images were obtained to evaluate glistenings, which were graded subjectively at the slitlamp and quantified objectively by digital image analysis using computer software.RESULTS: The study enrolled 80 patients. There were no significant differences in PCO between the 2 groups. The 3-piece IOL group had significantly fewer glistenings (P
