儿童白内障Ⅰ期后囊连续环形撕囊临床观察

Clinical observation of posterior continuous curvilinear capsulorhexis in operation of cataract intraocular lens implantation in children.

目的 探讨 期后囊连续环形撕囊对儿童后发障的预防作用。方法 对 42例 (4 8只眼 )在植入人工晶状体前施行 斯后囊连续环形撕囊 ,术后随访 2个月至 2年。结果 术后矫正视力≥ 0 .5者有 2 1只眼 ,占 48.3% ,随访期间有 40只眼 (83.3% )保持中央视轴区透明或基本透明。术后未发现严重并发症。结论 儿童白内障摘除联合人工晶状体植入术中施行 期后囊连续环形撕囊 ,安全有效 。

Objective To investigate the effect of posterior continuous curvilinear capsulorhexis(PCCC)in preventing posterior capsular opacification(PCO) after posterior chamber intraocular lens implantation in children.Methods The PCCC was performed on 42 cases(48 eyes)before the posterior chamber intraocular lens was implanted.The follow-up ranged from 2 months to 2 years.Results 40 eyes(83.3%)could keep the central visual axis transparent.The best corrected visual acuity was improved to 0.5 or over in 21 eyes(48.3%) at three months postoperatively.None of the cases was discovered to develop serious complications.Conclusion PCCC can not prevent the development of posterior capsular opacification completely,but it can reduce posterior capsular opacification effectively.
