多焦点人工晶状体植入的研究进展

白内障是导致患者视力下降乃至失明的主要原因之一，手术是治疗白内障确切有效的手段。随着科学技术的进步，传统的复明性白内障手术逐渐过渡到屈光性白内障手术。各种屈光性人工晶状体也应运而生，传统的单焦点人工晶状体(single focus intraocular lens, SIOL)不再是患者的唯一选择，多焦点人工晶状体(multifocal intraocular lens, MIOL)越来越被患者接受和认可。本文对现有的多焦点人工晶状体进行了归纳总结，通过分类列举，简述不同类型多焦点人工晶状体的多种特点及评估患者术后临床效果的方法，以期为眼科医生提供参考。

Research progress on multifocal intraocular lens implantation

Cataract is one of the most common causes of vision loss and even blindness in patients, and surgery is a proven and effective treatment option. Traditional cataract surgery for vision loss has increasingly given way to refractive cataract surgery as science and technology have progressed. There are also a variety of refractive intraocular lenses on the market place. Patients are increasingly accepting and recognizing multifocal intraocular lens(MIOL)as an alternative to traditional single focus intraocular lens(SIOL). Through classification and listing, the existing MIOL are discussed in this article, as well as the features of different types of MIOL and techniques for evaluating the clinical impacts of patients after surgery, so as to provide references for ophthalmologists.
