婴幼儿单眼无晶体眼接触镜配戴效果评价

Clinical evaluation of soft contact lens for monocular aphakia children

目的：评价婴幼儿单眼无晶体眼配戴亲水性角膜接触镜的效果。方法：对眼外伤和先天性白内障术后婴幼儿单眼无晶体眼１２ 例，选择屈光度为＋１０Ｄ～＋１３Ｄ、基弧７．８～８．４ｍｍ 的亲水软镜，配戴６～４０ 月，进行视力、眼部生理检查、双眼融合力，以及立体视觉测定。结果：患儿均无严重并发症，戴接触镜后平均视力为４．５，戴接触镜后能进行正常双眼融合者６ 例，改善程度达５０ ％ 。结论：婴幼儿在其监护人的帮助下，配戴接触镜是安全的，视力较矫正前明显提高，斜视的避免关键在于坚持规范配戴和积极的弱视治疗，戴镜后屈光参差减少，双眼融合功能和立体视得到改善，从而提高了视觉质量。

Objective:To evaluate the clinical efficiency of fitting soft contact lens for monocular aphakia children.Methods:12 case of monocular aphakia children from trauma or congenital cataract were enrolled.The soft contact lenses were fitted were +10D～+13D with BC 7.8～8.4mm.Their visual acuity,ocular physiology,binocular fusion and stereo acuity were assessed by follow up 6～40 months.Results:No ocular phathology occured.The monocular visual acuity were up to average 4.5.Binocular fusion were improved among 6 case (50%),and the stereo visiual acuity were turned to normal among 8 case.Conclusion:The soft contact lens is acceptable for aphakia children under the monitor of their parents.It improves the visual acuity,binocular fusion and stereo visual acuity.It can be used as early as possible for monocular aphakia children to prevent the amblyopia and refractive strabismus.
