目的 针对儿童外伤性白内障后房型人工晶状体植入术探讨防止后发障最简便有效的方法.方法 将41例儿童单眼外伤性白内障后房型人工晶状体植入术病例分为晶状体后囊完整组(23例)与晶状体后囊破损组(18例),对晶状体后囊浑浊发生率进行1～2年的随访、视力对比分析.结果 发现晶状体后囊浑浊发生率达91.2%,其中后囊完整组远期绝大部分发生程度不同的浑浊,矫正视力在0.5以上者仅为21.7%,后囊破损组发现周边残留后囊虽有浑浊,但中央视轴区透明,远期矫正视力在0.5以上者仍占61.1%.结论 在儿童外伤性白内障人工晶状体植入术中如后囊完整常规作一期后囊截开是防止后发障及维持远期较好视力的最简便有效方法.
Objective To investigate the most convenient and effective method to prevent posterior capsulotomy in pediatric traumatic cataract with posterior chamber intraocular lens implantation.Methods 41 cases of children with monocular traumatic cataract posterior chamber intraocular lens implantation were divided into complete posterior capsule group (18 cases) and the incidence of posterior capsular opacification of the lens were followed up for 1 to 2 years, the visual acuity was analyzed.Results The incidence of posterior capsule opacity was 91.2%, of which the posterior capsule complete group was far Most of the degree of occurrence of different degrees of turbidity, corrected visual acuity of 0.5% or more were only 21.7%, posterior capsule damage group found that although the residual posterior capsule is cloudy, but the central visual axis is clear, long-term corrected visual acuity of 0.5 or more Accounting for 61.1% .Conclusion It is the most simple and effective method to prevent posterior obstacle and maintain long-term good visual acuity in traumatic cataract intraocular lens implantation in children.
