To determine whether anterior capsule polishing during cataract surgery done by phacoemulsification has any effect on the rate of posterior capsule opacification.
We conducted a 3 year retrospective analytical study at our hospital. The medical records of patients who underwent cataract extraction by phacoemulsification with foldable square edge hydrophilic PCIOL between April 2007 and March 2010 were reviewed. The study included 1009 eyes of 950 patients who underwent phacoemulsification with foldable square edge hydrophilic IOL in the bag implantation with anterior capsular polishing. The control group included 981 eyes of 957 patients in whom anterior capsular polishing was not done. Patients in the age group of 45-65 years with well dilating pupils were included in the study. They were evaluated at 1 week, 1 month and 1 year post-operatively. Exclusion criteria included glaucoma, shallow anterior chamber, uveitis, high myopia, pseudoexfoliation, diabetes mellitus, traumatic cataracts, posterior polar cataract, subluxated cataracts, previous ocular surgeries, patients allergic to dilating drops, and steroid intake. Intraoperatively, the exclusion criteria were not achieving the total anterior capsule cover on the IOL optic, sulcus fixated IOL, and any intraoperative complications like posterior capsule rupture. After bimanual irrigation/aspiration, all enrolled patients were randomly assigned to receive either 360 degree anterior capsular polishing or No anterior capsular polishing and results were studied.
The rate of posterior capsule opacification in the study group and in the control group was not statistically significant.
Though it was thought that anterior capsular polishing will lead to reduced rate of PCO formation, our study showed that there was no significant difference in PCO formation between the two groups. However, it was seen that the rate of anterior capsule opacification and capsular phimosis showed a significant reduction in cases in which anterior capsular polishing was done.
确定白内障超声乳化手术中进行前囊抛光是否对后囊混浊发生率有任何影响。
我们在我院进行了一项为期3年的回顾性分析研究。回顾了2007年4月至2010年3月期间接受超声乳化白内障摘除术并植入可折叠方形边缘亲水性后房型人工晶状体的患者的病历。研究纳入了950例接受超声乳化白内障摘除术并植入可折叠方形边缘亲水性人工晶状体且行囊袋内植入及前囊抛光的患者的1009只眼。对照组包括957例未进行前囊抛光的患者的981只眼。年龄在45 - 65岁、瞳孔充分散大的患者纳入研究。术后1周、1个月和1年对他们进行评估。排除标准包括青光眼、浅前房、葡萄膜炎、高度近视、假性剥脱、糖尿病、外伤性白内障、后极性白内障、晶状体半脱位、既往眼部手术史、对散瞳滴眼液过敏的患者以及服用类固醇药物的患者。术中，排除标准为人工晶状体光学部未完全覆盖前囊、沟内固定人工晶状体以及任何术中并发症如后囊破裂。在双手灌注/抽吸后，所有纳入患者被随机分配接受360度前囊抛光或不进行前囊抛光，并对结果进行研究。
研究组和对照组的后囊混浊发生率无统计学差异。
尽管曾认为前囊抛光会导致后发性白内障形成率降低，但我们的研究表明两组之间后发性白内障形成无显著差异。然而，发现进行前囊抛光的病例中前囊混浊率和囊膜挛缩率显著降低。
