Interest in the prediction of the postoperative visual performance before the implantation of a multifocal intraocular lens (IOL) has increased in recent years.1 For individual predictions, new devices have emerged with the aim of simulating how the patient would see after surgery with the implantation of a multifocal IOL.2–6 However, the main drawback of these technologies is that they would underestimate the postoperative visual performance with increasing age, especially after 50 years of age.7 Another approach is to predict the mean visual performance of the population depending on

从多焦点人工晶状体的光学模拟预测视敏度和对比度灵敏度。

近年来，对预测多焦点人工晶状体（IOL）植入术后视觉性能的兴趣增加了。1对于个人预测，已经出现了新的设备，其目的是模拟患者植入手术后的视线然而，这些技术的主要缺点是随着年龄的增长，尤其是在50岁以后，它们会低估术后的视力。[7-6]另一种方法是预测视情况而定的人群的平均视力。在
