  • Patent number: 10379380
    Abstract: Translating contact lenses which are truncated for correcting presbyopia and whose design is optimized to maximize translation ability while maintaining comfort when the lens is worn on eye. Truncation of the lenses results in a non-round geometry while still retaining under-lid residency in select portions of the lens itself. Maximum thickness and back surface radius of curvature along with ramp shape can be optimized individually or in combination to maximize translation of the lens relative to the eye, when the lens is positioned on eye.
    Type: Grant

  • Patent number: 10379381
    Abstract: An optimized contact lens design and method which leverages the strain energy of the system when placed on eye that improves centration, translation, and stabilization characteristics, or any combination thereof, in order to improve both comfort and vision. A contact lens design and methodology wherein the lens-eye resulting strain energy is optimized to achieve the desired function be it centration, translation, or stabilization. Since the lens strain energy is directly driven by the amount of lens deformation, it is possible to control the lens strain energy through the modulus of the material, design of the lens geometry, namely the radii or curvature, peripheral thickness profiles, edge or rim shapes. The surface pressure and/or lens strain energy can be optimized for a given population by averaging the ocular eye shape/surface. Alternatively the lens strain energy can be optimized for a single given eye (i.e., custom design).

  • Patent number: 9091865
    Abstract: Feature patterns may be incorporated into the peripheral region of the back curve surface of contact lenses in order to increase tear exchange between the contact lens and the cornea. The feature patterns may be based upon fractal geometry and be incorporated anywhere in the periphery of the lens. The placement feature patterns are preferably determined utilizing a combination of simulations and experimentation.
