摘　　要：目的：探讨不同方法一期后囊截开对儿童白内障后房型人工晶体植入术后晶体后囊膜混浊的预防作用。方法：对28例（31只眼）儿童先天性白内障和外伤性白内障分别采用一期后囊膜切开、部分切除或联合前部玻璃体切除及后房型人工晶体植入术。术后随访3个月以上。结果：出院时矫正视力≥0．5者达71％，随访显示80％术眼视轴区透明，眼底清晰可见。结论：一期切开或部分切除后囊在一定程度上预防儿童白内障术后晶体后囊膜混浊的发生。对于穿通伤所致晶体囊膜破孔较大者宜联合前部玻璃体切除术。To evaluate the efficacy of various primary posterior capsulotomies in preventing posterior capsular opacity after cataract extraction with posterior chamber lens implantation in children. 28 cases(31 eyes)of congenital and traumatic cataracts in children were treated by primary posterior capsulotomy or capsulectomy,or the combined anterior vitrectomy and posterior chamber lens implantation. Corrected visual acuity was 0.5 or better in 71% of all the eyes and the results of follow-up showed 80% of the eyes remained transparent in the optic area. It's demonstrated that capsulectomy is effective in preventing the posterior capsular opacity after cataract extraction with posterior chamber lens implantation in children.Moreover, combined anterior vitrectomy should be performed in those with the anterior capsule severely damaged.
