We measured contrast sensitivity binocularly in different light conditions in nine patients with bilateral diffractive multifocal intraocular lenses (IOLs) and nine patients with bilateral monofocal IOLs. In general, the diffractive multifocal group had a lower mean contrast sensitivity. Patients completed a questionnaire that asked about their vision under daylight, twilight, and sunshine conditions. Monofocal patients had complete visual restitution in all light conditions. Multifocal patients reported several visual problems, especially when driving at night, but also in normal daylight and cloudy weather conditions.
我们在不同光照条件下对9例植入双侧衍射多焦点人工晶状体（IOL）的患者和9例植入双侧单焦点IOL的患者进行了双眼对比敏感度测量。总体而言，衍射多焦点组的平均对比敏感度较低。患者完成了一份问卷，问卷询问了他们在日光、黄昏和阳光条件下的视力情况。单焦点患者在所有光照条件下视力均完全恢复。多焦点患者报告了一些视觉问题，尤其是在夜间驾驶时，但在正常日光和阴天条件下也有问题。
