Visual rehabilitation of patients with aniridia and progressive cataract is a challenging clinical problem. Reduced corneal transparency, limitations of iris support, and decreased zonular integrity may make extracapsular cataract surgery difficult. Four patients with familial aniridia had substantial visual improvement after successful extracapsular cataract extraction (ECCE) with implantation of capsular-fixated posterior chamber intraocular lenses (PC IOLs). In one patient, it was combined with trabeculectomy to treat chronic open-angle glaucoma. Posterior chamber IOLs can be safely implanted in the aniridic eye normalities in the anterior segment.
无虹膜合并进行性白内障患者的视觉康复是一个具有挑战性的临床问题。角膜透明度降低、虹膜支撑受限以及悬韧带完整性下降可能会使囊外白内障手术变得困难。4例家族性无虹膜患者在成功进行囊外白内障摘除术（ECCE）并植入囊袋固定型后房型人工晶状体（PC IOL）后，视力有显著改善。在1例患者中，它与小梁切除术联合用于治疗慢性开角型青光眼。后房型人工晶状体可以安全地植入前段正常的无虹膜眼中。
