Patent number: 9551883Abstract: The present invention is directed to a non-deforming contact lens for keratoconus patients having a displaced central zone. In particular, the central zone is displaced from the geometric center of the lens. The shape of the central zone is egg or spoon-shaped and is rotationally asymmetrical with one semi-meridian that is shorter than a corresponding semi-meridian. An intermediate transition zone is formed integral with the periphery of the central zone, and a peripheral zone is formed integral with the periphery of the intermediate transition zone, forming a round contact lens.Type: GrantFiled: December 9, 2014Date of Patent: January 24, 2017Assignee: VICOH, LLCInventor: Jerome A. Legerton

Patent number: 8894208Abstract: This application describes a kit of contact lenses comprising two or more contact lenses having a known higher order aberration for each given lens power. By way of example, the higher order aberration may comprise a spherical aberration, a coma aberration, or a trefoil aberration. A practitioner selects a lens from the kit and applies the lens to a patient's eye and measures a residual higher order aberration of the lens-eye system. In cases where the residual higher order aberration exceeds a predetermined magnitude, the practitioner selects a second lens from the kit, applies the second lens to the patient's eye and measures the residual higher order aberration of the lens-eye system.Type: GrantFiled: March 29, 2013Date of Patent: November 25, 2014Assignee: Vicoh, LLCInventor: Jerome Legerton

Patent number: 8388130Abstract: The present invention is directed to a non-deforming contact lens comprising a central zone and a peripheral zone, wherein the central zone has a radius of curvature approximately equivalent to a central curvature of an underlying cornea, wherein the central zone is progressively aspheric with an initial zone approximately elliptical and then progressing to a parabolic shape and then to a hyperbolic shape. The peripheral zone reverses the progressive asphericity of the central zone, and includes a terminating local radius that is shorter than a radius at a junction of the central zone and the peripheral zone.Type: GrantFiled: November 3, 2008Date of Patent: March 5, 2013Assignee: Vicoh, LLCInventor: Jerome A.
