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 prevention of posterior capsular opacification in children under 6 years old with cataract. Methods A total of 56 patients (80 eyes) aged 6 years undergoing implantation of cataract were randomly divided into two groups. Group A was treated with one-stage continuous posterior capsulorhexis (PCCC); Group B received one stage PCCC + anterior vitreous cut. Results Two years after operation, there were 27 eyes of posterior capsule opacification group Ⅱ and 5 eyes of group B, the difference was significant between the two groups (χ2 = 21.73, P <0.01). Visual acuity (year 2) was also significantly different between the two groups (t = 2 16 2, P <0 05). Conclusion The first stage of PCCC + anterior vitrectomy is a truly effective method to prevent posterior capsular opacification after cataract surgery in children. It should be the first choice for cataract surgery in children under 6 years of age.
