Abstract: Presbyopia is age-related reduction in amplitude of accommodation and can not reading comfortably. Current methods such as single-focus glasses or bifocal glasses or progressive additional lens are the most widely used for correction of presbyopia. All surgical solutions for presbyopia do not improve the physiological amplitude of accommodation. This article is an attempt to review the advances in surgical management of presbyopia.
Key words: Presbyopia/Suerery; Dioptric; Eye
随着老龄化社会的来临，老视已影响近约半数的人群，对老视矫正的光学性与手术性手段的需求亦将与日俱增。目前老视的基本概念是因年龄相关性调节幅度的下降使得近阅读渐渐困难的一种生理老化现象，而老视形成的真正机制目前仍未完全阐明，盖因于与其直接相关的调节机制目前亦存在争议，虽然目前普遍接受Helmholth经典调节理论[1]。现阶段老视矫正的主流方式是配戴单焦框架眼镜、双焦框架眼镜和渐变多焦点眼镜，而近5年来用手术方法矫正老视逐渐成为热点。然而，目前所有针对老视的手术方法都未能带来持久的真正生理意义上的调节改善，对老视矫正手术方法的开展必须持谨慎的、理智的、不含任何一点受商业经济驱动的科学态度。本文就目前各种老视矫正手术方法（包括单眼视方法的、施于角膜的、施于巩膜的与施于晶状体的）的现状与发展趋势做一述评。 |
