目的 探讨儿童白内障人工晶体植入术后后囊混浊的预防处理方法。 方法 对 5 9例 65眼儿童白内障人工晶体植入患者随机分为两组。甲组行一期连续环形后囊撕囊联合术后球结膜下注射5 氟尿嘧啶。乙组单纯行一期连续环形后囊撕囊。结果 术后随访 3年Ⅱ级以上后囊混浊甲组 5眼 ,乙组 1 3眼 ,两组比较有显著差异 (χ2 =5 2 7,P <0 0 5 )。视力≥ 1 0甲组 1 6眼 ,乙组 6眼 ,两组比较也有显著差异 (χ2 =6 42 ,P <0 0 5 )。结论 一期连续环形后囊撕囊术后联合球结膜下注射 5 氟尿嘧啶能有效防止儿童白内障人工晶体植入术后后囊混浊的发生。
Objective To investigate the preventive treatment of posterior capsular opacification after cataract surgery in children. Methods 59 cases of 65 children with cataract intraocular lens implantation were randomly divided into two groups. A group of a continuous annular posterior capsulotomy combined with subconjunctival injection of 5-fluorouracil. Group B simple a continuous annular capsulorhexis. Results There were 5 eyes of posterior capsule opacification group Ⅱ and 13 eyes of group B after 3 years of follow-up. There was significant difference between the two groups (χ2 = 527, P <0 05). Visual acuity was ≥10 in group A and 16 in group B, and 6 in group B. There was also significant difference between the two groups (χ2 = 6 42, P <0 05). Conclusions A continuous annular posterior capsulotomy combined with subconjunctival injection of 5-Fluorouracil can effectively prevent the occurrence of posterior capsular opacification in children with cataract after intraocular lens implantation.
