儿童白内障手术后二期人工晶状体植入的探讨

目的 探讨儿童白内障术后二期人工晶状体植入术的效果。方法 回顾了34例(41眼)儿童白内障手术后二期人工晶状体植入5年记录。介绍了二期人工晶状体植入的适应证，人工晶状体植入的手术方法。术前、术后视力、屈光不正。双眼状态和手术方法。结果 34例(41眼)儿童白内障手术后二期人工晶状体植入。其中8眼成功囊袋内植入，28眼睫状沟植入，余5眼行后房人工晶状体悬吊术。41眼中35眼(85．37％)有可测量的视力提高，有3眼视力降低2行。24眼(58．54％)与对侧眼的矫正屈光度差在 1．50D以内。31眼(75．61％)屈光度差在 3．00D以内。结论 对于不能耐受接触镜或眼镜的儿童无晶状体眼，二期后房型人工晶状体植入是一种安全、有效的选择。

Secondary intraocular lens implantation after cataract surgery in children

Objective To report results of secondary implantation after cataract surgery in children.Methods We reviewed clinical records for a five-year period of patients who had cataract surgery in childhood and received a secondary intraocular lens,we studied indications for secondary intraocular lens implacement;surgical procedures for intraocular lens implantation;preoperative and postoperative visual acuity,refractive error, and binocular status;and complications of the procedure.Results A secondary intraocular lens was placed in 41 eyes of 34 patients who had cataract surgery in childhood in 8 eyes,the lense were placed in the capsular bag. In 28 eyes,the lense were placed in the ciliary sulcus.The other five eyes had insufficient capsuar support for an intraocular lens,were fixed to the sclera. 35 of 41eyes (85.37%) had measurable improvement in visual acuity of 1 line.Conclusion Secondary placement of an intraocular lens in the posterior chamber appears to be a safe, effective alternative for correction of aphakia in the contact lens-or spectacles intolerant child or young adult.
