Presbyopia is a physiological aging situation that the plasticity and elasticity of the lens and the function of the ciliary muscle become weaker, resulting in a decreased accommodation and inability to focus on near objects. Nowadays, there are many clinical strategies to correct presbyopia, each of which has its own advantages and disadvantages, however, there is no true sense of way to restore accommodation function. This article reviews both worldwide and domestic research on presbyopia, and analyzes and summaries the status quo as well as research progress of presbyopia correction modalities, surgical approaches, and drug therapies, hoping to provide a reference for clinical works.
老视是指随着年龄增长，晶状体的可塑性和弹性下降，睫状肌功能变弱，导致眼的调节幅度下降，进而使近距离工作和阅读发生困难的生理老化现象。目前临床治疗老视的方法众多，各有优劣，但尚无真正意义改善调节功能的方法。本文汇总国内外老视治疗的相关研究，就老视治疗中的戴镜矫正治疗、手术治疗和药物治疗的现状及进展进行分析和总结，以期为临床开展工作提供参考。.
