  • Publication number: 20130222766
    Abstract: 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.

  • Publication number: 20130141890
    Abstract: According to various embodiments of the invention, an LED lighting system is providing having a replaceable driver module. In some embodiments, the replaceable driver module comprises a component that is physically attachable to an LED illumination module, whereby the attached components have a combined physical profile dimensioned for installation in a pre-existing light fixture. In further embodiments, the combined system's dimensions allow it to be installed in pre-existing fluorescent fixtures without requiring rewiring of the fixtures. In some embodiments, the LED driver module may be configured to condition power received from a fluorescent light ballast to drive the LEDs such that a pre-existing fluorescent ballast does not need to be removed. In other embodiments, the LED driver may be configured to condition main power such that a pre-existing fluorescent ballast may be removed.

  • Patent number: 8388130
    Abstract: 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.

  • Patent number: 8246167
    Abstract: In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure (e.g., corneal reshaping or by way of a contact lens) that focuses the peripheral image field in at least one meridian in front of the mid peripheral retina. In general, the therapeutic optical structure places the peripheral image field with reference to the retina in the direction and amplitude that growth is needed in order that the emerging myopia would be regulated. In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure that further produces a central retinal image that is focused on the central retina in at least one meridian so as to not reshape the central cornea.

  • Publication number: 20120105804
    Abstract: 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.

  • Publication number: 20120109595
    Abstract: The invention is directed to a contact lens design and methods of manufacturing, fitting and using such lenses. The contact lens may be designed for use in a corneal refractive therapy (CRT) program. The lens provides a design which allows proper fitting of a patient, whether for corrective contact lenses or for a CRT program. Due to the rational design of the lenses according to the present invention, a minimal number of lens parameter increments can be identified to cover the range of common corneas. It is therefore possible to provide pre-formed lens buttons or blanks which are easily formed into a final design, thereby simplifying and speeding up the treatment process. Further, any adjustment of the lens design which may be required based upon trial fitting or the like, is easily envisioned and implemented by the fitter.
