Multiple Lens Patents (Class 623/6.32)
  • Patent number: 6554859
    Abstract: An intraocular lens for implantation in an eye of a patient includes a multifocal optic and a movement assembly. The optic has maximum add power which is less than the add power required for full near vision for a pseudophakic eye. The movement assembly is coupled to the optic and is adapted to cooperate with the eye of the patient to effect accommodating movement of the optic in the eye. Lens systems including two optics and two movement assemblies are also provided. The intraocular lenses and lens systems are particularly useful when implanted in the eyes of a patient after removal of the natural lenses.

  • Patent number: 6464725
    Abstract: A lens system for implantation in a human eye which makes it possible to restore accommodation. The lens system comprises one anterior lens (2) and a posterior lens (4), out of these two lenses one has positive and the other has negative lens power. Accommodation is achieved by varying the distance between the two lenses. This lens system can be made so as to generate large changes in optical power for small changes in position. It also allows the amount of change in optical power for any given amount of change in distance between the lenses to be selected relatively independently of the optical power of the overall lens system.

  • Patent number: 6454801
    Abstract: A supplemental intraocular lenses may be attached to conventional primary intraocular lenses using annular wrap-around clamps or adhesive. New primary intraocular lens configurations have pockets for accommodating relatively small, supplemental intraocular lenses therein.

  • Patent number: 6413276
    Abstract: A method of correcting optical aberrations and abnormalities within the optical system of an eye having an intraocular lens implanted therein. The method includes the step of measuring and determining the extent of the aberrations and abnormalities. Removing at least one removable component of the intraocular lens. Modifying at least one surface of the removable component to eliminate or correct the aberrations and abnormalities. Reinserting the modified removable component within the intraocular lens in the optical system through a same wound formed to originally implant the intraocular lens.

  • Patent number: 6358280
    Abstract: An artificial lens including a lens system having eccentric axes for in an eye having a macula and an enlarged natural pupil is shown. The artificial lens comprises a first optical lens system and a second optical lens system. The principal axis of each optical lens system is eccentric to each other and the distance between each principal axis is selected to enable the first optical lens system and the second optical lens system to be operable within the enlarged pupil. The lens system of the artificial lens system directs light rays from each image of each lens of the first optical lens system and second optical lens system onto a fovea centralis of the macula of an eye. In the preferred embodiment, a prism having a preselected diopter power is positioned on a selected surface of one of the first optical lens system and second optical lens system for directing light rays from an object onto a fovea centralis of the macula of an eye. A contact lens having an eccentric optical system is also shown.

  • Patent number: 6280471
    Abstract: An IOL that is free of glare and the halo effect associated with conventional IOLs and a method for using the same is provided. The IOL is adapted for implantation into an eye, in place of or in addition to the natural lens of the eye, to adjust a refractive power of an eye. The IOL includes at least one lens portion and a light-absorbing material. The lens portion has first and second surfaces and a perimeter connecting the first and second surfaces which extends entirely about the lens portion. The first and second surfaces can have any suitable shape to provide the lens portion with a suitable refractive power. The light-absorbing material is disposed to absorb light propagating in a direction towards the perimeter to thus eliminate glare and the halo effect caused by such light. One or more haptics, which include a light absorbing material, can be attached to the lens portion for mounting the IOL in the eye.

  • Patent number: 6197058
    Abstract: A corrective intraocular lens system comprises a primary intraocular lens for implanting into an individual's aphakic or phakic eye. The primary intraocular lens includes an optic portion having an optical axis and an anterior surface and a posterior surface, and includes attachment means for maintaining the optic portion centered along the optical axis of the individual's eye. The optic portion is formed having a narrow recess or groove formed into the anterior surface adjacent peripheral regions of the optical portion. The recess may extend completely or only partially around the optic. Included is an elastically deformable, corrective secondary intraocular lens having an optic portion with an anterior surface and a posterior surface.

  • Patent number: 6197057
    Abstract: A supplemental intraocular lens is provided for implantation in the eye to modify the lens system of the eye comprising the cornea and the natural lens or an intraocular lens already implanted in the eye, to create a modified lens system having teledioptic or other diffractive capabilities to correct for macular degeneration. To create the teledioptic lens system, the supplemental intraocular lens has substantially no refractive power except for a high minus lens portion at its center. The supplemental intraocular lens, when implanted on the natural or previously implanted artificial lens in the eye and used without an external lens, allows light rays entering the eye onto the retina of the eye as they would without the supplemental intraocular lens, thus providing unmagnified and peripherally unrestricted vision.
