白内障术后实现全程视力设计方案概述

随着人工晶状体设计的不断改进,白内障患者对术后视觉质量有了进一步的要求.白内障术后全程视力的设计方案不断得到完善：早期提出双眼植入单焦点人工晶状体的Monovision方案;随着多焦点人工晶状体的设计及发展,又提出双眼植入多焦点人工晶状体及双眼混合植入多焦点人工晶状体的矫正方案;及可调节人工晶状体双眼植入的矫正方案.现就对提高白内障患者全程视力的设计方案及人工晶状体发展历程、设计原理、临床研究及其设计方案的优势及局限性等方面进行阐述.

Design of achieving full range vision after cataract surgery

With the development of intraocular lens (IOL) design, patients ask for better visual quality after cataract surgery. Now we have achieved some improvement in design of achieving full range vision: the first is Monovision program posed at early stage, which the two eyes are implanted with monofocal IOL; with the development of multifocal IOL, bilateral implantation with multifocal IOL of the same size or with multifocal IOL of the different size; with the coming up of accommodating IOL, bilateral implantation with accommodating IOL becomes popular. The present paper is a review of the design of achieving full range vision after cataract surgery, and its development history, design principle, and its advantage and limitation.
