自1951年Ridley报告白内障摘出术后施行人工晶体眼内植入以来,世界各地逐渐推广应用,迄今为止,临床报告已达6万例以上。此种手术被认为是使术后单眼无晶体眼恢复视功能较为理想的方法。兹仅就有关问题综述如下。人工晶体的优点白内障摘出术后一般必须以高度凸透镜矫正方能获得有用之视力。但配戴普通矫正眼镜时所见物像(节点)近移、物体变形、视野狭窄(只有35～55°)、外周模糊,且因眼底成像扩大25％而不能两眼单视,故单眼无晶体眼时无法配戴普通眼镜。接触眼镜虽无上述缺点,但装卸麻烦,约有
Ridley since 1951 Ridley report the implementation of intraocular lens implantation after implantation, the world has been gradually applied, so far, the clinical report has reached more than 60,000. This kind of surgery is considered to be a better method of restoring the visual function of the monocular aphakia. Here is a summary of the relevant issues. The advantages of intraocular lens surgery after cataract extraction generally must be highly convex lens to obtain useful visual acuity. However, wearing ordinary corrective glasses seen when the image (node) near the object deformation, narrow field of vision (only 35 ~ 55 °), the outer blur, and due to 25% of the fundus imaging expansion can not be the two single vision, so monocular Crystalline eye can not wear ordinary glasses. Although the above shortcomings of contact lenses, but loading and unloading trouble, about
