To evaluate the effect of different surgical methods for management of the posterior capsule and anterior vitreous on the rate of posterior capsule opacification in pediatric cataracts.
Charts of 34 children (47 eyes) aged 40 days to 18 years (mean: 8.5 years) who had primary cataract surgery with or without posterior chamber intraocular lens (IOL) implantation during the past 5 years were reviewed. In 26 eyes, cataracts were managed with a posterior continuous curvilinear capsulorhexis, and in 21 eyes, the posterior capsule was left intact. Follow-up averaged 10 months (range: 6.5 months to 5 years).
Visually significant secondary cataract developed in nine eyes with intact posterior capsules, and seven eyes required Nd:YAG laser posterior capsulotomy. The average time for YAG capsulotomy postcataract removal in the second group was 4 months. The visual axis remained clear in all eyes that had posterior continuous curvilinear capsulorhexis with or without posterior chamber IOL. Complications such as fibrinoid membrane, stromal edema, posterior synechiae, updrawn pupil, and transient glaucoma occurred in both groups at a similar rate.
Primary posterior continuous curvilinear capsulorhexis is an effective method for preventing secondary cataract formation in pediatric cataracts.
评估小儿白内障手术中处理后囊膜和前部玻璃体的不同手术方法对后囊膜混浊发生率的影响。
回顾过去5年中34例年龄在40天至18岁（平均8.5岁）的儿童（47只眼）行一期白内障手术（有或无后房型人工晶状体植入）的病历。26只眼采用连续环形撕囊处理白内障，21只眼后囊膜保持完整。随访平均10个月（范围：6.5个月至5年）。
9只后囊膜完整的眼发生了具有明显视力影响的继发性白内障，7只眼需要Nd:YAG激光后囊膜切开术。第二组白内障摘除术后行YAG囊膜切开术的平均时间为4个月。所有行连续环形撕囊（无论有无后房型人工晶状体）的眼视轴均保持清晰。两组中类纤维膜、基质水肿、虹膜后粘连、瞳孔上移和短暂性青光眼等并发症的发生率相似。
一期连续环形撕囊是预防小儿白内障继发性白内障形成的有效方法。
