Segmented Zones Patents (Class 623/6.19)
  • Patent number: 11103344
    Abstract: An optical device (2300) including a partial or incomplete optic (2320) configured operatively as an add-on (e.g., supplemental lens/optic) for an (existing) optical element or system, the partial or incomplete optic having an active area configured in relation to the optical element or system such that the partial or incomplete optic controls or changes foci of light incident upon or provided to the active area, but does not control or change foci of light bypassing optically relevant portions of the partial or incomplete optic, and associated methods for enhancing vision.

  • Patent number: 7993399
    Abstract: A lens system is provided. The lens system includes a lens adapted to be positioned along the main optical axis of the eye and a control unit. The control unit is operable with the lens to alter the focal length of the lens based at least partly upon a condition, such that the lens alters light rays and focuses the rays on the retina of the eye.

  • Patent number: 7722670
    Abstract: According to an embodiment of the present invention, an implant device may be provided. The implant may be adapted to manipulate the position of an eyeball associated with a patient, whereby the device comprises an insertion device including a first and a second portion. The first portion may include a first thickness and may be adapted to elevate the position of the eyeball. The second portion may include a second thickness and/or a second position relative the first portion for moving the position of the eyeball in a forward direction.

  • Patent number: 6596025
    Abstract: A narrow profile, glare reducing, refractive mono-focal intraocular lens is described that comprises an optic having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range. A transition zone between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens is implanted. The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.

  • Publication number: 20030033013
    Abstract: This patent represents a deformable artificial intraocular lens for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The rings allow the lens to have extremely thin edges, which reduce glare, halos, and distortion. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. This lens represents a breakthrough in removal of mass from the lens. The ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient. The lens and haptic design reduces the radial forces on the eye to the point where the naturally occurring pressures in the eye move the lens thus providing accommodation.
