Abstract

We describe the case of a 77-year-old man with asteroid hyalosis who had phacoemulsification and implantation of a plate-haptic intraocular lens (IOL). Intraoperatively, a tear occurred in the anterior capsule, and vision loss occurred 3 months after a neodymium:YAG posterior capsulotomy. Because of the asteroid hyalosis, a posteriorly dislocated IOL, which occurred after the capsulotomy, was difficult to diagnose. Careful retinoscopy established the aphakic condition of the eye, and the B-scan ultrasonography indicated the IOL's location.

摘要

我们描述了一例患有星状玻璃体变性的77岁男性患者，其接受了超声乳化白内障吸除术并植入了一片式人工晶状体（IOL）。术中，前囊膜出现撕裂，钕:钇铝石榴石激光后囊切开术后3个月出现视力丧失。由于存在星状玻璃体变性，后囊切开术后发生的人工晶状体后脱位难以诊断。仔细的视网膜检影确定了患眼的无晶状体状态，B超检查显示了人工晶状体的位置。
