儿童白内障人工晶体植入的疗效观察

Cataract Extraction with Intraocular Lens Implantation in Children

目的 评价儿童白内障摘除人工晶体 (IOL)植入术的疗效。探讨手术的最佳时机、人工晶体屈光度的选择及并发症。方法 对 4 2例 (4 5眼 ) 4～ 14岁儿童先天性和外伤性白内障摘出 ,Ⅰ期或Ⅱ期人工晶体植入术。结果 术后矫正视力≥ 0 5者 19眼 (4 2 % ) ,视力在 0 1～ 0 3者 15眼 (33% ) ,视力 <0 1者 5眼(11% ) ,欠合作者 6眼 (14 % )。术后前房有纤维素形成者 18眼 (4 0 % ) ,后囊混浊者 16眼 (36 % )。结论 儿童先天性白内障和外伤性白内障摘除人工晶体植入术是有效的方法 ,但应掌握手术时机、选择度数适当的人工晶体 ,积极治疗术后并发症。

Objective To evaluate the therapeutic effect of cataract extraction with intraocular lens(IOL) implantation in children. To investigate the best opportunity of implantation, choice of diopter, prevention and treatment of complications. Methods Cataract extracapsular extraction with IOL implantation was performed in 42 cases (45 eyes) of congenital and traumatic cataract aged from 4 years to 14 years old. Results The postoperative corrected visual was more than 0.5 on 19 eyes (42%), from 0.1 to 0.3 on 15 eyes (33%), less than 0.1 on 5 eyes (11%), incorporation on 6 eyes (14%). Fibrous exudation in anterior chamber after the surgery were found on 18 eyes (40%). The posterior capsular opacity were occurred in 16 eyes (36%). Conclusion IOL implantation is a useful method in pediatric cataract, but the opportunity of implantation should be considered, proper IOL's power should be chosed, the postoperative complications should be well managed.
