Abstract:Presbyopia is an age-related physiological phenomenon characterized by a gradual decline in the accommodation of the eye leading to difficulty in near vision. With the acceleration of population aging, presbyopia has gradually become a global public health problem. At present, the correction methods of presbyopia mainly include optical correction, surgical correction and drug treatment, which can improve the near vision disorder. However, each of the above treatments has its own advantages and disadvantages. Optical correction can be fitted with single focal convex lens, progressive multifocal glasses, etc., which are the most common and economical correction methods, but frequently removal of glasses will cause inconvenience in life. Surgical correction can be carried out by changing the refractive performance of the cornea, replacing the intraocular lens and scleral surgery, and patients can get rid of glasses after surgery, but each surgical method has its own advantages and disadvantages. Drug treatment, including miosis drugs and lens softeners, is expected to become a new method for non-invasive presbyopia correction, but there is currently a lack of clinical trials and evidence-based medical evidence. This article reviews the treatment methods and research progress of presbyopia.
