摘　　要：目的 观察先天性白内障术后视力及立体视恢复情况.探讨视功能变化的影响因素.方法 将33例（56只眼）先天性白内障患儿据手术时年龄3月至2岁,＞2～6岁分为A、B两组,A组21例36只眼,B组12例20只眼,对术后平均随访3年的最佳矫正远视力及远近立体视恢复情况进行分析.结果 术后脱盲率,A组为100%,B组为90%,两组之间的差别无统计学意义（P＞0.05）;脱残率,A组为94%,B组为70%,两组之间差别具有统计学意义（P＜0.05）;远立体视的获得率A组为58.8%,B组为16.7%,两组之间差异均具有统计学意义（P＜0.05）;近立体视获得率A组为70.6%,B组为41.7%,两组之间差异无统计学意义（P＞0.05）.结论 先天性白内障患儿视功能恢复与手术年龄有关,手术年龄越小,视功能恢复越好.Objective To investigate the factors of visual function change after congenital cataract extraction and intraocular lens （IOL） implantation through the observation of visual acuity and stereosis. Methods A total of 33 cases were divided into 2 groups according to operation age, 3 months-2 years old was named group A, 2-6 years old was named group B. To analyze the best corrected distant visual acuity and the near and distance stereo-acuity after cataract extraction with IOL implantation. They were followed up for an average of 3 years. Results After operation, 100% and 90% patients were relieved from blindness in group A and group B respectively, and two groups did not show difference （P 〉0.05）; 94% and 70% patients obtained corrected vision ≥ 0.3 in group A and group B, and two groups showed significant difference （P 〈0.05）; 70.6% and 41.7%patients gained the near stereo acuity in group A and group B respectively, the recovery rate of the near stereo-acuity did not show difference （P 〉0.05）; 58.8% and 16.7% patients acquired the distance stereo acuity in group A and group B respectively, the recovery rate of the distance stereo-acuity showed significant difference between two groups （P 〈0.05）. Conclusions The recovery of visual function of child＇s congenital cataract is related to the operation age. And the children can get better visual function if they accepte surgery earlier.
