We describe opacification of a plate-haptic silicone intraocular lens (IOL) caused by calcification in a diabetic patient with asteroid hyalosis. The IOL was explanted 48 months after uneventful phacoemulsification because opacification of the posterior surface was causing significant visual disturbance. Light and scanning electron microscopy and x-ray spectrometry of the explanted IOL showed the opacification consisted mainly of calcium and phosphate, presumably hydroxyapatite, in the form of precipitations on the posterior surface of the optic.
我们描述了一名患有星状玻璃体病变的糖尿病患者，其植入的一片式触觉硅酮人工晶状体（IOL）因钙化而发生混浊。在白内障超声乳化手术顺利完成48个月后，该IOL被取出，因为其后表面混浊导致了严重的视觉障碍。对取出的IOL进行光镜、扫描电子显微镜检查及X射线光谱分析显示，混浊主要由钙和磷酸盐组成，推测为羟基磷灰石，以沉淀物的形式存在于晶状体光学部的后表面。
