自1949年英国Ridley首先施行人工晶状体植入术以来，经过数十年在手术技术、人工晶状体制作工艺等各方面的改进，良好的手术效果使单焦点人工晶状体已在世界范围内广泛应用，但术后的无调节使得患者术后仍需配戴眼镜，如何使无调节力的人工晶状体眼转变为具有较好拟调节力的人工晶状体眼成为目前眼科领域研究的热点，本文拟就这一领域研究较多的多焦点人工晶状体（multifocal intraocular lens,M-IOL）的术后视功能恢复情况做一综述。主要介绍了近几年其术后远近视力、中间视力、视野、对比敏感度、双眼视功能、散光等几方面内容的研究情况。
Abstract The first IOL implantation was performed by Ridlley since 1949.its inspiring effect after operation results in wildly use.but post -operation patients still need to be wear glasses due to none-accommodation because its monofocality.it is a focal point that how to make the change from none-accommodation to accommodation. multifocal intraocular lens with pseudo- accommodation was investigated and its visual function of post-operation will be reviewed here.
