先天性小眼球人工晶体植入术

Intraocular lens implant in microphthalmos

先天性小眼球为先天发育异常,包括小角膜,虹膜脉络膜缺损及眼球震颤。此病可为散发性,也可为遗传性;可以单独存在眼病,也可伴有全身异常。白内障常发生于先天性小眼球。文中总结6人10例先天性小眼球合并白内障接受人工晶体植入术的病人。角膜直径9mm 以上视力恢复较满意,8mm 以下的眼球效果差。这些总结表明人工晶体植入术对先天性小眼球是比较安全和成功的。

Microphthalmos is a developmental disorder of the eye consisting of a smaller cornea,coloboma of iris and choroid and nystagmus.It can present as an isolated disease or associate with other systemic disor- ders.Cataract commonly occurs in these eyes.Ten eyes which received cataract extraction and intraocular lens implant were reviewed in this paper.If the diameters of the cornea are smaller than 8mm,the surgical results arc not good;otherwise it is safe and successful.
