Abstract: An optical device comprising an optical hydrogel with select regions that have been irradiated with laser light having a pulse energy from 0.01 nJ to 50 nJ and a wavelength from 600 nm to 900 nm. The irradiated regions are characterized by a positive change in refractive index of from 0.01 to 0.06, and exhibit little or no scattering loss. The optical hydrogel is prepared with a hydrophilic monomer.

Abstract: The invention is directed to an optical device comprising refractive optical structures, wherein the refractive structures are characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material.

Abstract: A method for modifying the refractive index of an optical, polymeric material. The method comprises irradiating select regions of the optical, polymeric material with a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000 nJ. The irradiation results in the formation of refractive optical structures, characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material. The method can be used to modify the refractive index of an intraocular lens following the surgical implantation of the intraocular lens in a human eye.

Abstract: An ophthalmic lens, comprising at least one optic including a first zone and a second zone having a second zone. The lens configured such that, when the lens is applied to an average eye, for objects located between infinity and a near focal plane of the average eye, an MTF of the eye's optical system has no phase reversals.

Abstract: An aspect of the invention is directed to an ophthalmic lens, comprising at least one optic comprising a lens zone. The zone is configured such that, when the lens is located in an average eye, for all object locations along an axis in a range from infinity to 1.0 diopters, for light having a wavelength 550 nm, the wavefront at the retina formed by the lens zone has the following characteristics 0.01 ? ? Z 40 Z 20 ? ? 5.0 , and 0.01?|Z60|?1.0 waves of 550 nm light. In some embodiments, 0.01?|Z80|?0.5 wave for light having a wavelength 550 nm.
