6岁以下儿童白内障术后后囊混浊手术预防的研究

Surgery prevention against posterior capsular opacity after IOL operation in children under 6

目的 探讨 6岁下儿童白内障人工晶体术后后囊混浊的预防方法。方法 对 5 6例 80眼 6岁下儿童白内障人工晶体植入患者随机分两组 ,A组 ,单纯行一期连续环行后囊撕囊术 (PCCC) ;B组行一期PCCC +前部玻璃体切除术。结果 术后随访 2年Ⅱ级以上后囊混浊A组 2 7眼 ,B组 5眼 ,两组比较有差异 (χ2 =2 1 73,P <0 0 1)。视力 (第 2年 ) ,两组比较也有差异 (t =2 16 2 ,P <0 0 5 )。结论 一期PCCC +前部玻璃体切除术是真正有效预防儿童白内障人工晶体术后后囊混浊发生的术式 ,应为 6岁以下儿童白内障首选的手术方法。

Objective To investigate the management and prevention of posterior capsular membrane opacity after IOL operation on children under 6-year. Methods 56 cases (80 eyes) of child cataract were randomly divided into two groups, A and B. For group A, continuous circular posterior capsular-tearing (PCCC) was performed immediately after cataract extraction; while for group B, both PCCC and anterior vitrectomy. Results Two-year follow-up revealed that posterior capsular opacification (grade 2 or over) was found in 27 eyes of group A and 5 eyes of group B. The difference is of statistical significance (χ 2=21.73, P<0.01). The difference in visual acuity is also significant between the two groups (t=2.162,P<0.05). Conclusion PCCC plus anterior vitrectomy after cataract surgery is an effective method for preventing secondary cataract formation in infants and children and should be regarded as the first choice for patients under 6.
