Objective To observe the clinical effect of capsule incarcerated surgery IOL in treatment of pediatric cataract children. Method 48 cases (62) cataract children in our hospital from January 2013 to June 2013 were treated as the objects of study, randomly divided into observation group and control group, 24 cases (32) of observation group patients took phacoemulsiifcation cataract extraction + posterior capsule circular capsulorhexis + anterior vitrectomy + IOL posterior capsule membrane incarcerated, 24 cases (32) of control group patients took phacoemulsification cataract extraction + posterior capsule circular capsulorhexis + anterior vitrectomy + IOL intracapsular implantation. The two groups of children were random access 12 months, and compared the two groups of children with visual acuity improvement, central visual axis area muddy conditions and occurrence of complications. Result Postoperatively, the two groups of patients also appear a certain degree of improved visual acuity, observation group patients vision> 0.5, 0.3~0.5 percentage respectively rose from preoperative 12.5%, 12.5%to 53.1%, 12.5%, the difference rose were statistically signiifcant (P < 0.05);control group patients vision> 0.5, 0.3 ~ 0.5 scale, respectively rose from preoperative 6.7%, 10.0%to 26.7%, 36.7%, the differences were statistically signiifcant (P<0.05);observation group of patients vision>0.5 was 53.1%, signiifcantly better than that of control group (26.7%) (P<0.05). After surgery, the proportion of children in the central visual axis region observed group cloudy 0, 1, 2, 3, 4, respectively, 28.1%, 53.1%, 15.6%, 3.1%, 0.0%;the proportion of children in control group was 6.7%, 30.0%, 40.0%, 16.7%and 6.7%, the differences were statistically signiifcant (P<0.05);after surgery, the two groups of children had no retinal detachment, vitreous hemorrhagic disease. Corneal edema, anterior chamber ifbrinoid exudate and anterior chamber lfare compared between the two groups were not statistically signiifcant (P>0.05). Conclusion phacoemulsiifcation cataract extraction+posterior capsule circular capsulorhexis+anterior vitrectomy+IOL posterior capsule membrane incarcerated can effectively promote children's visual acuity and central visual axis area improve turbid conditions, and will not signiifcantly increase the incidence of postoperative complications, safe and effective, worthy of promotion.%目的：观察人工晶状体后囊膜嵌顿术治疗儿童白内障的临床效果。方法选择本院2013年1月至2014年6月收治的白内障患儿48例（62眼）作为研究对象，随机分为观察组与对照组，观察组24例（32眼）患儿采取超声乳化白内障摘除＋后囊膜环形撕囊＋前部玻璃体切除＋人工晶状体后囊膜嵌顿术治疗，对照组24例（30眼）患儿给予超声乳化白内障摘除＋后囊膜环形撕囊＋前部玻璃体切除＋人工晶状体囊袋内植入术治疗，随访12个月，比较两组患儿术后视力改善情况，中央视轴区混浊情况及并发症发生情况。结果术后两组患儿的视力情况均得到一定程度的改善，观察组患儿视力＞0.5、0.3～0.5比例分别由术前的12.5%、12.5%升高为53.1%、40.6%，差异有显著性（P＜0.05）；对照组患儿视力＞0.5、0.3～0.5比例分别由术前的6.7%、10.0%升高为26.7%、36.7%，差异有显著性（P＜0.05）；观察组患儿视力＞0.5的比例为53.1%，显著优于对照组（26.7%）（P＜0.05）。术后观察组患儿中央视轴区混浊0级、1级、2级、3级、4级的比例分别为28.1%、53.1%、15.6%、3.1%、0.0%，对照组分别为6.7%、30.0%、40.0%、16.7%、6.7%，组间对比差异具有显著性（P＜0.05）；术后两组患儿均无视网膜脱落、玻璃体出血症发生，两组患儿角膜水肿、前房纤维素样渗出及前房闪辉发生率组间对比差异均无显著性（P＞0.05）。结论超声乳化白内障摘除＋后囊膜环形撕囊＋前部玻璃体切除＋人工晶状体后囊膜嵌顿术治疗儿童白内障，能有效促进患儿的视力恢复，并有效改善中央视轴区混浊情况，且不会明显增加术后并发症，安全有效，值得推广。
