Claim 13:
14. An optical contact lens including central optical and outer peripheral zones comprising an optical polymer material, wherein select regions of the optical device have been irradiated with a focused, visible or near-IR laser below the optical breakdown threshold of the optical polymer material to provide refractive structures that exhibit a change in refractive index, and exhibit little or no scattering loss, and wherein ablation or removal of the optical polymeric material is not observed in the irradiated regions, and wherein the refractive structures provided are configured to form at least one peripheral zone having a different dioptric power around a center zone of the contact lens, so as to place a myopic defocus on the peripheral retina of an eye of a patient when the contact lens is placed on cornea of the eye.
