OPAQUE CORNEAL INSERT FOR REFRACTIVE CORRECTION
First Claim
1. An intracorneal implant for insertion into a cornea of a human eye, the eye having an anterior surface and a posterior surface, said implant comprising an elongated arcuate member comprising an opaque portion extending along at least a portion of a periphery of the arcuate member, and the implant being configured to alter the refractive properties of the cornea by altering the curvature of a surface of the cornea.

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.

21. A method for affecting the shape of a cornea of an eye, the method comprising:
-
separating a first corneal layer and a second corneal layer at a location anterior to a pupil of the eye; and altering the anterior surface of the cornea to affect the refractive properties thereof by placing an opaque member between the first and second corneal layers. - View Dependent Claims (22, 23, 24, 25, 26, 27)
