Presbyopia is a ubiquitous visual disability of the aging eye, affecting more than one-third of the United States and one-half of Asian populations, whereby the crystalline lens progressively loses its ability to accommodate. With an estimated prevalence of 80,000,000 emme-tropic presbyopes in the United States alone, corneal inlays have emerged as a promising surgical option for nonlens-based treatment of presbyopia. The current generation of inlays for the treatment of presbyopia may be broadly grouped into categories based on mechanism of action (Fig. 1). Different implantation techniques and technologies exist; including both mechanical and femtosecond laser-enabled platforms to create pockets and flaps. A major advantage of corneal inlays is that they are removable, relatively easy to reposition, and can be combined with other refractive procedures to treat ametropia and presbyopia.
