摘要
目的探讨后囊连续环形撕囊联合前部玻璃体切割术治疗儿童白内障术后后发性白内障的疗效。方法选取先天性白内障患儿62例（68眼）,超声乳化后行后囊连续环形撕囊及前部玻璃体切割术,一期囊袋内植入人工晶状体,术后随访2a以上,观察术后视力及后发性白内障发生情况。结果 68眼中有5眼在术后3个月至2a出现后发性白内障,占7.35%,平均出现时间为16个月。术后2~3个月复查矫正视力,0.2~0.4者17眼,0.5~0.7者28眼,≥0.8者20眼;手术前后视力比较,差异有统计学意义（P〈0.05）。后发性白内障发生率经年龄分组比较,差异无统计学意义（P〉0.05）。所有患儿均未发生黄斑囊样水肿或视网膜脱离等并发症。结论后囊连续环形撕囊联合前部玻璃体切割术是预防后发性白内障发生较为有效的方法。
Objective To investigate the surgical method for decreasing the incidence of posterior capsule opacification（PCO）after cataract surgery in children.Methods A total of 62 children with congenital cataract（68 eyes）were collected to take posterior continuous curvilinear capsulorhexis and anterior vitrectomy after phacoemulsification.Intraocular lens were implanted into capsular bag at the first period of time.All patients were followed up for 2 years;Postoperative visual acuity and condition of PCO were observed.Results In 68 eyes,there were 5 eyes（7.35%）with PCO at postoperative 3 months to 2 years,average in 16 months.Corrected visual acuity was rechecked at postoperative 2 months to 3 months.There were 17 eyes with visual acuity from 0.2 to 0.4,28 eyes from 0.5 to 0.7 and 20 eyes more than 0.8.Statistical difference was found in visual acuity between before and after surgery（P0.05）.There was no difference in incidence of PCO among different age groups（P0.05）.No child was found with cystoid macular edema or retinal detachment.Conclusion Posterior continuous curvilinear capsulorhexis combined with anterior vitrectomy is an effective way to prevent PCO.
