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。
Objective: To explore the preventive effects of posterior capsule capsulotomy with different methods on posterior capsule opacification of posterior chamber intraocular lens implantation in children with cataract. Methods: 28 cases (31 eyes) children with congenital cataract and traumatic cataract were treated with one-stage posterior capsulotomy, partial resection or combined with anterior vitrectomy and posterior chamber intraocular lens implantation. Follow-up after 3 months. Results: Discharge corrected visual acuity ≥ 0.5 were up to 71%, follow-up showed 80% ophthalmology visual axis clear, fundus clear. CONCLUSION: One-stage incision or partial resection of the posterior capsule may prevent the occurrence of posterior capsule opacification in children after cataract surgery. For penetrating injury caused by larger capsular bag hole should be combined with anterior vitrectomy.
