Abstract
Implants configured for corneal implantation are disclosed that have a light transmitting portion and a light-blocking portion disposed about the periphery of the implant. The implant can be an elongate member, such as a split or continuous ring, that can be implanted in the cornea to alter the refractive properties of the cornea by altering the curvature of the anterior surface of the cornea, thereby providing corrective refraction. The light-blocking portion can reduce edge effects, which may be visible or distracting to the patient.
