摘　　要：目的 探讨儿童外伤性白内障人工晶状体（IOL）植入术的临床疗效及影响因素.方法 对本院2001年1月～2006年6月的136例3～14岁儿童外伤性白内障的临床资料进行分析.结果 手术脱盲率为92.2%,脱残率为78.9%.8～14岁的脱残率（90.3%）明显高于3～7岁者（68.7%）.应用超声乳化吸出术联合植入肝素处理的聚甲基丙烯酸甲酯（PMMA）硬性IOL,或植入疏水性丙烯酸酯（Actysof）折叠式IOL均可减少后囊浑浊的发生.术后主要并发症为葡萄膜炎、后囊浑浊、继发性青光眼、IOL瞳孔夹持及虹膜粘连.结论 儿童外伤性白内障IOL植入术后视力恢复受多种因素影响,如患儿术前视觉发育状态（与年龄相关）、受伤性质及程度、手术时间的选择、IOL的选择及术中术后并发症的处理等.Objective To investigate clinical effect and influencing factors of pediatric traumatic cataract extraction and intraocular lens implantation. Methods Analyzed clinical data of 136 cases with traumatic cataract aged 3 - 14years old who were in our hospital from January,2001 to June, 2006. Results After surgery, there were 92.2% cases relieved from blindness and 78.9% cases whose corrected vision were 0.3 or better. In the 8 - 14 years old group, the cases whose corrected vision were 0. 3 or better were in 90.3% ,but in the 3 -7 years old group were in 68. 7%. The incidence of posterior capsule opacification was reduced by the use of phacoemulsification,implantation with hepar in modified polymethylmethacrylate （PMMA） IOL or Acrysof IOL. The surgical complications were uveitis, posterior capsular opacification, secondary glaucoma, IOL pupilary capture and posterior synechia of iris. Conclusions The vision after traumatic cataract extraction and intraocular lens implantation in children are influenced by many factors： the vision developing state before surgery, the quality and extent of the injury, the selection of surgery time and IOL kind, the treatment of operative and postoperative complications.
