老视矫治手术治疗最新进展

Surgical options for the correction of presbyopia

老视是一种年龄相关的生理性老化现象。老视手术治疗已逐渐成为屈光手术最终需要面对的挑战。目前，其手术矫治包括眼外（施于角膜或巩膜）和眼内（晶状体置换或施于晶状体本身）两大策略，如角膜准分子激光手术、热传导成形术、飞秒激光基质内环形切开术、角膜植入物手术、各种多焦人工晶状体植入术、可调节人工晶状体植入术、晶状体软化术、巩膜扩张术等。各种手术方法均存在自身的优势和不足。本文就目前现有和近期即将问世的老视治疗方法及其被关注的问题作一综述。

Presbyopia is an age-related eye condition, and its most prominent sign is the reduction in the amplitude of accommodation, resulting in the disability to modify the focus from far to near of the eyes. Surgical therapy of presbyopia still remain great challenge for refractive surgeons. Surgical strategies of presbyopia include extraocular （corneal or scleral） and intraoeular procedures, such as excimer laser surgery, conductive keratoplasty, INTRACOR, corneal inlays, multiple types of multi-focal or accommodating intraocular lens,laser-assisted presbyopia reversal,scleral expansion bands, etc. Each procedure owns its unique advantages and disadvantages. This review attempted to address the surgical options available and likely to be available in the near future and discuss the key problems in presbyopia procedures.
