  • Patent number: 10080649
    Abstract: Visual aids and associated methods for improving the eye sight of low vision patients are provided. Generally, the devices of the present disclosure address the needs of age-related macular degeneration (AMD) and other low vision patients by providing a magnified retinal image while keeping a large visual field of view. Further, the devices of the present disclosure allow direction of the magnified retinal image away from damaged portions of the retina and towards healthy, or at least healthier, portions of the retina. The devices of the present disclosure are also configured for implantation within the eye using minimally invasive surgical procedures. Methods of utilizing the devices of the present disclosure, including surgical procedures, are also provided.
    Type: Grant

  • Patent number: 8652205
    Abstract: A diffractive multifocal design for ocular implant is provided. This ocular implant includes a diffractive multifocal intraocular lens (IOL) and a number of haptics. The diffractive multifocal IOL passes optical energy to distance, intermediate and near foci. The haptics mechanically couple to the diffractive multifocal IOL in order to position and secure the diffractive multifocal IOL within the eye. The diffractive multifocal IOL may include both a diffractive region and a refractive region, the diffractive multifocal IOL operable to phase shift optical energy such that constructive interference occurs within the diffractive region and the refractive region.
