On-Eye Corneal Crosslinking for Control of Progressive Myopia and Treatment of Presbyopia

Abstract

A method of treating progressive myopia or presbyopia in a patient includes performing crosslinking of at least some regions of a patient's cornea (1). The crosslinking is performed in an annular area (6) generally centered on the cornea and in a central area (7) inside the annular area. The crosslinking affects the refraction of the eye so as to change the focus on a peripheral region of the retina (3) by moving a portion of the focal surface (2) of the eye's image anteriorly (5) relative to the peripheral region, and the crosslinking affects the refraction in a central region (11) of the retina by moving a portion of the focal surface of the eye's image posteriorly direction relative to the central region. A device for performing the method includes a scleral contact lens including a UV emitter configured to emit UV light in the annular area and/or the central area.
