儿童白内障人工晶状体植入探讨

Discussion on intraocular lens implantation for cataract children

目的探讨儿童人工晶状体（ＩＯＬ）植入时机、屈光度选择、术式及疗效。方法总结１组儿童ＩＯＬ植入资料。结果术后视力以外伤障、先天性非致密白内障恢复较好（＞０．５占４７．６％）；先天性致密白内障或外伤性角膜白斑严重者多呈低视力状态。后发障发生率高（４９％）。植入晶状体屈光度平均２０．１Ｄ。结论视轴上各型致密儿童白内障尽早摘除，植入ＩＯＬ最早年龄３岁为宜。９岁前选择略低于标准成人度数。

ObjectiveTo discuss the earliest age of intraocular lens (IOL) implantation,the choice of diopter of IOL,the way of implantation and the effect of the therapy.MethodsThe clinical data of IOL implantation for a group of cataract children was summerized and analyzed retrospectively to seek meaningful and relative index.ResultsAfter operation,vision of traumatic and congenital uncompact cataract patients recovered better(47.6%>0.5).Most of the congenital compact cataract and traumatic corneal scar patients had low vision.The incidence of thickened posterior capsule in post operation was 49%.The average diopter of IOL was 20.1 D.As time went on,the patients became or had the tendency to be myopia.ConclusionIt’s better to imperatively remove all kinds of compact cataract on the optic axis for children as early as possible.Below the age of 3 contact lens or spectacles is the first choice after operation and then secondary implantation after the age of 3.For children over 9 the formula SRK Ⅱ can be used for calculation of diopter of IOL.Under this age the diopter of IOL should be less than that.
