Laser refractive correction of presbyopia

Abstract

Presbyopia is an inevitable and progressive loss of the eye’s ability to focus on nearby objects due to aging, which affects everyone regardless of their refractive error. Uncorrected presbyopia is a significant burden worldwide and affects the quality of life. Conservative options include spectacle correction, contact lenses, and pharmacologic agents. Spectacles are commonly used to correct vision, but have certain drawbacks such as peripheral blur and impaired depth perception. These limitations have been associated with an increased risk of accidental falls. Several surgical options are available to address these issues, including cornea-based, lens-based, or scleral procedures. These procedures involve modifying the cornea’s optics, replacing the crystalline lens, or attempting to restore accommodation. Each of the options has its benefits and limitations. One of the most common surgical methods of presbyopic correction that has recently become popular is presbyopic Laser assisted In situ keratomileusis (LASIK) due to its improved safety and efficacy. This article is a review of all the currently available data and studies regarding the various methods of correction of presbyopia, with an emphasis on the principles and outcomes of the corneal laser refractive procedures for presbyopia correction, such as PresbyLASIK, Supracor, PRESBYOND laser blended vision, and Custom Q.
