简介：目的：探讨后囊膜撕开联合前段玻璃体切除治疗先天性白内障的临床疗效。方法：对40例48眼先天性白内障患者行超声乳化吸除术,并行后囊膜撕开联合前段玻璃体切除,观察术前、术后视力及并发症。结果：患者48眼中有5眼（10%）在术后3mo～1a出现后发性白内障,术后常见并发症有：角膜水肿、前段葡萄膜炎反应、后发性白内障。结论：后囊膜撕开联合前段玻璃体切除能有效降低后发性白内障出现,是一种安全有效的手术方式。

简介：目的：探讨超声乳化术治疗玻璃体切割术后并发性白内障的手术特点、安全性及临床疗效。方法：对39例39眼玻璃体切割术后并发性白内障的患者行超声乳化术，其中对有硅油充填的23眼联合硅油取出术，观察手术前后视力及术中、术后并发症。术后随访3～24（平均10）mo。结果：所有病例术中无严重并发症发生。术后最佳矫正视力37眼（95％）提高，2眼（5％）无改变，无视力下降者。1眼硅油取出后2wk视网膜脱离复发，1眼术后1mo玻璃体出血，均行玻璃体切割联合硅油填充术而治愈。无脉络膜出血、低眼压等并发症。结论：玻璃体切割术后并发性白内障眼内情况复杂，手术难度大，超声乳化术是一种安全有效的手术方法。
