Abstract

UNLABELLED

Two cases of postoperative intraocular lens (IOL) calcification in patients implanted with the Akreos Adapt IOL at the time of combined phacovitrectomy are described, along with clinical review of all patients implanted with this IOL type at our institution between November 2006 and September 2008. The IOLs explanted from the 2 cases were examined using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The SEM of the explanted IOLs showed crystalline anterior surface and subsurface deposits; by EDX, the deposits showed high concentrations of calcium and phosphorous, consistent with calcium apatite. Twenty patients (20 eyes) attended for cohort review, and none showed IOL opacification. The reason calcification occurred in the 2 cases remains unknown, but clinicians should be aware of this potential complication.

摘要

未注明

本文描述了 2 例在施行联合白内障玻璃体切除术后发生人工晶状体（IOL）后囊膜下钙化的病例，同时回顾了我院 2006 年 11 月至 2008 年 9 月期间所有植入该型 IOL 的患者。对这 2 例病例中取出的 IOL 进行扫描电子显微镜（SEM）和能谱（EDX）检查。SEM 显示，取出的 IOL 前表面和亚表面有结晶状沉淀物；EDX 显示，沉淀物中钙和磷含量较高，符合磷酸钙。20 例患者（20 只眼）参加了队列研究，均未发现 IOL 混浊。2 例发生钙化的确切原因尚不清楚，但临床医生应意识到这种潜在的并发症。
