【摘要】 良好的调节是人眼视功能重要的组成部分,能为我们提供不同距离清晰的视觉图像。单焦点人工晶状体,不能满足患者术后中、近距离用眼的需求。多焦点人工晶状体是利用特殊的光学设计,将进入眼内的光线分配到远、中、近的不同焦点聚焦,从而提供全程视力;而可调节人工晶状体则采用了类似人类晶状体的调节原理,通过人工晶状体的光学部在囊袋内前后位置移动,来改变光学节点,从而达到既能看远,也能看近的目的。本文就多焦点和可调节型人工晶状体的特点、临床应用,特别是其术后效果和可能出现的视觉症状做一综述。更多还原

【Abstract】 Good accommodation is an important part of the human eye’s visual function, which can provide us clear visual images in different distances. Monofocal intraocular lens (IOL) can not meet patients with postoperative needs of middle to near distance vision. Multifocal IOL makes use of special optical design, distributing the entered light to far, middle and near different focuses to provide full range of vision; While accommodative IOL uses accommodation principle similar to the human lens, which changes the optical nodes through forward and backward translocation of the optic part of IOL in the capsular bag so as to achieve the purpose not only to see far but also to see near. In this paper, the characteristics, clinical applications, especially postoperative effects and possible visual symptoms of multifocal and accommodative IOLs are reviewed.更多还原
