Over-refraction provides a powerful method for the refractive examination of the aphakic or highly ametropic patient. Nevertheless, in the past, practical difficulties that attend mathematical or graphical combination of over-refraction and original spherocylinders have tended to limit the clinical use of over-refraction methods. Programmable calculators, now available inexpensively, render over-refraction clinically practical. An over-refraction program for the Texas Instruments TI-59 Card-Programmable Calculator is presented. Program running time, exclusive of data entry and readout, is under 15 sec.
复验法为无晶状体眼或高度屈光不正患者的屈光检查提供了一种有力的方法。然而，过去，在将复验法结果与原始球柱镜度数进行数学或图形组合时所遇到的实际困难，往往限制了复验法在临床上的应用。现在价格便宜的可编程计算器使复验法在临床上切实可行。本文介绍了一种适用于德州仪器TI - 59卡片可编程计算器的复验法程序。程序运行时间（不包括数据输入和读出）在15秒以内。
