To prospectively compare postoperative results of two premium intraocular lenses EnVISTA (Bausch and Lomb) and AcrySof IQ (Alcon), focussing on glistenings and posterior capsule opacification. The evaluation of glistenings was done using Image J software and posterior capsule opacifications were quantified with OSCA system.
Twenty patients (7 men and 13 women) with bilateral cataract were included. EnVista intraocular lens (IOL) was implanted in one eye and AcrySof IQ IOL in the second eye of each patient. Objective evaluation methods were used for assessment. Glistenings was quantified with ImageJ software and PCO using the Open-Access Systematic Capsule Assessment (OSCA) system (Devised by Aslam TM, Edinburgh, United Kingdom). Complete ophthtalmological evaluation including evaluation after pupil dilatation was done and digital images of intraocular lenses were obtained. The results of 2-, 4-, 6- and 12-month follow-up were compared.
Twenty patients were analyzed 2 months, 16 patients 4 months, 14 patients 6 months and 13 patients 12 months after cataract surgery. There was only minimal difference in best corrected visual acuity between EnVista and AcrySof group. The glistenings in the EnVista IOLs was objectively lower than in the AcrySof IOLs during whole follow-up period. In contrast to PCO, in eyes with AcrySof IOL was lower PCO score.
Development of new materials and techniques of cataract surgery is the topic of ophthtalmologists worldwide. Reduction of glistenings and PCO is one of the main aims, objective measurements is important part of assessment of postoperative results after cataract surgery.

前瞻性比较两种高端人工晶状体EnVISTA（博士伦）和AcrySof IQ（爱尔康）的术后效果，重点关注晶状体后囊膜混浊及闪辉情况。使用Image J软件评估闪辉情况，并用OSCA系统对晶状体后囊膜混浊进行量化分析。
纳入20例双侧白内障患者（7例男性，13例女性）。每位患者的一只眼植入EnVista人工晶状体，另一只眼植入AcrySof IQ人工晶状体。采用客观评估方法进行评价。使用ImageJ软件对闪辉情况进行量化分析，使用开放获取系统囊膜评估（OSCA）系统（由英国爱丁堡的Aslam TM设计）对晶状体后囊膜混浊情况进行量化分析。进行包括散瞳后评估在内的完整眼科检查，并获取人工晶状体的数字图像。比较术后2个月、4个月、6个月和12个月的随访结果。
白内障手术后2个月对20例患者进行了分析，4个月时对16例患者进行了分析，6个月时对14例患者进行了分析，12个月时对13例患者进行了分析。EnVista组和AcrySof组之间最佳矫正视力仅有极小差异。在整个随访期间，EnVista人工晶状体的闪辉情况在客观上低于AcrySof人工晶状体。与晶状体后囊膜混浊情况相反，植入AcrySof人工晶状体的眼中晶状体后囊膜混浊评分较低。
白内障手术新材料和新技术的研发是全球眼科医生关注的课题。减少闪辉和晶状体后囊膜混浊是主要目标之一，客观测量是白内障手术后评估术后效果的重要组成部分。
