摘要:

探讨儿童白内障摘除和后房人工晶体(PC-IOL)植入术的疗效。方法：36例42眼先天性和外伤性白内障，年龄2～10岁，行囊外白内障摘除(ECCE)和PC-IOL植入，随访3个月至2年。结果：除6例患儿失访外，其余患儿术后最终视力都有增进，71%术眼视力≥0.5。术后主要并发症为后囊混浊占95%，10眼作了二期囊切开或YAG激光治疗。其它并发症有葡萄膜炎，IOL偏位，不可逆瞳孔散大及一过性眼压增高。结论：PC-IOL植入术是目前儿童白内障较好的复明手段，但应妥善处理术后并发症，并需要进行长期的随访观察。

Abstract:

To study the effects of cataract extraction with posterior chamber intraocular lens (PC-IOL)implantation in children. Methods:Extracapsular cataract extraction(ECCE) and PC-IOL imptantation operations were performed in 36 cases (42eyes)of congenital and traumatic cataract,aged from 2～10 years.The follow up ranged from 3months to 2 years.And the postoperative complications and management were also discussed.Results: The visual acuity was improved in most cases after surgery except 6 in which the follow up was lost.71% of the eyes achieved a visual acuity ≥05.The main complication was posterior capsule opacification,accounting for 95%.Secondary capsulotomy or YAG laser treatments in 10 eyes were performed.The incidence of other complications included dislocation of IOL(2eyes),atonic pupil(leye)and temporary high intraocular pressure(2eyes).Conclusions:PC-IOL implantation is a better method for the recovery of visual acuity in pediatric cataract at present.but the postoperative complications should be well managed. A long term follow up is required.
