随着人们对白内障术后视觉质量要求的提高，多焦点人工晶状体的应用已成为近年来的研究热点。目前多焦点人工晶状体主要分为折射型、衍射型和折射衍射混合型3类。本文拟就此三类多焦点人工晶状体的设计原理及其临床应用现状等作一综述。

As the visual quality requirements of the cataract surgery increase, the application of multifocal intraocular lens has been a hot research subject recently. So far, the multifocal intraocular lens has been divided into refractive multifocal intraocular lens, diffractive multifocal intraocular lens and hybrid multifocal intraocular lens. This article summarizes the progress of clinical application of three types of multifocal intraocular lens and their design principles.
