一、人工晶状体有哪些优点?我们知道,人眼的晶状体功能主要是聚光成像和调节焦距。在白内障手术摘除晶状体后,相当于摘除了一个10D～11D 屈光度的凸透镜。手术眼处于高度的远视状态,需用另一个相等度数的凸透镜来矫正。常用方法是戴眼镜或角膜接触镜(隐形眼镜),但二者都有很多缺点及特定适用范围。另一种方法是植入人工晶状体,优点如下:(1)符合解剖位置:白内障囊外摘除术后,后房型人工晶状体置于原来晶状体 First, what are the advantages of intraocular lens? We know that the human lens is the main focus of the condenser imaging and adjust the focal length. After cataract surgery to remove the lens, the equivalent of removing a 10D ~ 11D diopter convex lens. Surgery eyes in a high degree of hyperopia, the need to use another lens of equal degree to correct. Common methods are wearing glasses or contact lenses (contact lenses), but both have many disadvantages and specific areas of application. Another method is the implantation of intraocular lens, the advantages are as follows: (1) consistent with anatomical location: extracapsular cataract extraction, posterior chamber intraocular lens placed in the original lens
