摘要
先天性无虹膜症是一种少见的眼部遗传病，合并白内障几率很高，通常需要手术治疗，但该类白内障手术难度大、风险高、术后视力提高有限。虹膜型人工晶状体的植入虽然可以改善畏光症状，但存在继发青光眼、角膜内皮失代偿等严重并发症，应慎重应用。由于患者同时合并其他先天异常，白内障术后密切随诊，及时处理相应眼部改变对预后非常重要。
Congenital aniridia is a rare genetic eye disease. There is a high cataract prevalence in these patients and the cataract surgery usually required. But the kind of cataract surgery is difficult and usu- ally in high risk. The postoperative visual acuity improved limited. The symptoms of photophobia can be de- creased when iris-type IOL was implanted, but there are serious complications of secondary glaucoma, corneal endothelial decompensation, etc. So the iris-type IOL should be carefully applied. Because patients are also associated with other congenital anomalies, it is very important to the prognosis that the patients is closely followed up and do something for ocular changes accordingly in time after cataract surgery.
