先天性白内障手术中预防后发障的方法

目的　探讨小儿先天性白内障手术中预防后发障的方法。方法　对 46例 ( 4 6眼 )先天性白内障 ,以白内障超声乳化仪的注吸I/A系统吸净晶状体植入人工晶状体后 ,进行后囊连续环形撕囊及前段玻璃体切除联合手术 (A组 ) ,同期施行的3 2例 ( 3 2眼 )先天性白内障 ,以同样的方法行白内障摘出人工晶状体植入后 ,进行单纯后囊连续环形撕囊术 ,不做前段玻璃体切除 ,作为对照组 (B组 )。术后随访 2年以上。结果　后发障发生的情况 ,A组 2眼 ( 4 4% ) ,B组 7眼 ( 2 1 9% ) ,两组对比差异具有显著性意义 (P <0 0 5 )。两组均未发现眼底并发症。结论　先天性白内障术中行后囊连续环形撕囊联合前段玻璃体切除术 ,是预防后发性白内障的有效方法。

Preventing secondary cataract in congenital cataract operation

Objective To explore the method of preventing secondary cataract in congenital cataract operation.Methods 46 cases(46 eyes) congenital cataract were performed phacoemulsification and post continuous curvilinear capsularhexis(CCC) combined with anterior vitrectomy(the first group),compared with 32 cases(32 eyes) which were only performed phacoemulsification and post continuous curvilinear capsularhexis(the second group).All cases were followed over two years.Results 2 eyes(4.4%) occured secondary cataract in the first group.7 eyes(21.9%) in the second group.There was great singnificant difference between two groups( P <0.05).The complication of fundus was not found in the two groups.Conclusion Post CCC combined with anterior vitrectomy is an effective method for preventing secondary cataract.
