目的:对硅油填充眼硅油取出前后联合超声乳化白内障摘除手术的临床分析。 方法:玻璃体切割术后硅油填充眼并发白内障患者36例36眼，随机分为两组，一组硅油取出前行超声乳化白内障摘除术, 二组在硅油取出后联合超声乳化白内障摘除术。观察两组患者术中、术后并发症、术后前房反应、眼压、角膜内皮情况等。 结果:两组患者硅油均取出顺利，超声乳化白内障摘除植入人工晶状体，术中术后并发症对症处理。两种联合手术后角膜内皮细胞密度及六角形细胞比例下降，术后1wk六角形细胞比例、术后1mo细胞数量及形态均有显著差异（P<0.05）。 结论:硅油取出前联合超声乳化白内摘除术有相对轻的术后反应，术中并发症及更小的角膜内皮损伤。

AIM:To compare the effects of pre- and post- silicone oil removal combined phacoemulsification in silicone oil-filled eyes. METHODS: The clinical data of 36 patients (36 eyes) were analyzed. The 36 cataracts after silicone oil tamponade with pars plana vitrectomy were randomly divided into two groups. The two groups underwent combined phacoemulsification pre- and post-silicone oil removal respectively. The intraoperative and postoperative complications and postoperative anterior chamber reaction, intraocular pressure and corneal endothelium were observed. RESULTS:All patients operations were completed smoothly with silicone oil removal and IOL implantation, complications got effectively clinical control.The corneal endothelium cells densities and ratios of hexagonal cells were differently decreased.The ratios of hexagonal cells were significant difference between two groups of one week postoperatively. The corneal endothelial cell density and proportion of hexagonal cell were significant difference between two groups of one month postoperatively (P<0.05). CONCLUSION:The complications, anterior chamber reaction, and corneal endothelial lesion were less in group of pre-silicone oil removal combined phacoemulsification.
