Abstract

A method to measure the power of an intraocular lens (IOL) in situ using an extended range keratometer and a depth measuring apparatus is described. With this method, the IOL power was measured in ten patients with an anterior chamber IOL and in ten patients with a posterior chamber IOL and compared with the labeled power. The total mean error (measured power minus labeled power) was found to be 0.01 diopters (D) with a standard deviation of 0.22 D. The largest error was 0.40 D.

摘要

描述了一种使用扩展范围角膜曲率计和深度测量设备原位测量人工晶状体（IOL）屈光度的方法。采用该方法，对10例植入前房型人工晶状体的患者和10例植入后房型人工晶状体的患者进行了人工晶状体屈光度测量，并与标记屈光度进行比较。发现总平均误差（测量屈光度减去标记屈光度）为0.01屈光度（D），标准差为0.22 D。最大误差为0.40 D。
