Presbyopia is an age-related eye condition where one of the signs is the reduction in the amplitude of accommodation, resulting in the loss of ability to change the eye's focus from far to near. It is the most common age-related ailments affecting everyone around their mid-40s. Methods for the correction of presbyopia include contact lens and spectacle options but the surgical correction of presbyopia still remains a significant challenge for refractive surgeons. Surgical strategies for dealing with presbyopia may be extraocular (corneal or scleral) or intraocular (removal and replacement of the crystalline lens or some type of treatment on the crystalline lens itself). There are however a number of limitations and considerations that have limited the widespread acceptance of surgical correction of presbyopia. Each surgical strategy presents its own unique set of advantages and disadvantages. For example, lens removal and replacement with an intraocular lens may not be preferable in a young patient with presbyopia without a refractive error. Similarly treatment on the crystalline lens may not be a suitable choice for a patient with early signs of cataract. This article is a review of the options available and those that are in development stages and are likely to be available in the near future for the surgical correction of presbyopia.
老花眼是一种与年龄相关的眼部疾病，其症状之一是调节幅度降低，导致眼睛从远聚焦切换到近聚焦的能力丧失。它是最常见的与年龄相关的疾病，影响着每一个45岁左右的人。矫正老花眼的方法包括隐形眼镜和眼镜，但老花眼的手术矫正对屈光外科医生来说仍然是一项重大挑战。治疗老花眼的手术策略可能是眼外（角膜或巩膜）的，也可能是眼内的（摘除并置换晶状体或对晶状体本身进行某种治疗）。然而，有许多限制因素和需要考虑的问题限制了老花眼手术矫正的广泛应用。每种手术策略都有其独特的优缺点。例如，对于没有屈光不正的年轻老花眼患者，摘除晶状体并置换人工晶状体可能不是首选。同样，对于有早期白内障迹象的患者，对晶状体进行治疗可能也不是一个合适的选择。本文综述了现有的以及处于研发阶段且可能在不久的将来用于老花眼手术矫正的方法。
