摘　　要：自人工晶状体(IOL)问世以来,IOL屈光度数测算的精确性问题备受关注。随着眼科生物测量设备的不断发展及IOL屈光度数计算公式的多元化,IOL屈光度数测算的精确性越来越高,IOL的功能不断完善,屈光性白内障摘除手术的理念深入人心。然而,临床也存在一种现象,即过于追求白内障摘除手术后屈光度数的正视化,因而导致患者出现视觉不适。本文通过分析何种情况下预留屈光度数应为正视、近视状态、远视状态,指出白内障摘除手术IOL预留屈光度数应进行个体化选择。Since the advent of intraocular lenses(IOL),the accuracy of IOL measurements has been paid much attention.With the continuous development of eye biometric equipment and the diversification of IOL power calculation formulas,the precision of IOL power calculation has increased,the function of IOL has improved,and refractive cataract surgery has become popular.However,there is an excessive pursuit of the emmetropization of postoperative refraction after cataract surgery in order to demonstrate the accuracy of IOL measurements,and postoperative emmetropization may cause visual discomfort in some patients with preoperative myopia.This phenomenon is worthy of concern.
