[ I claim as my invention:] [12.]12. An intracorneal implant shaped to be inserted in an intracorneal channel in a circumferential direction about the optic axis of a human eye and configured to alter the curvature of the cornea to effect refractive correction of an eye, said implant comprising an elongated arcuate member having ends and having a polymeric outer portion having a first elastic modulus and a polymeric inner portion having a second elastic modulus, wherein the first elastic modulus differs substantially from the second elastic modulus.
