Three Filaments Patents (Class 623/6.53)
  • Patent number: 8480734
    Abstract: An accommodating intraocular implant apparatus is disclosed for implantation in the human eye. The apparatus includes an optic portion having a periphery and an optic axis, said optic portion lying substantially within an optic plane transverse to said optic axis; at least one flexible haptic extending from a point on or near the periphery of the optic portion; at least one flexible haptic having a fixation anchor portion distal to the periphery of the optic portion; and at least one flexible haptic having a centering anchor portion. The fixation anchor portion and the centering anchor portion are adapted to couple to a portion of the eye.

  • Patent number: 6824563
    Abstract: An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens has a first baseline diopter power for distance vision correction and the second ophthalmic lens has a second baseline diopter power for other than distance vision correction. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient or has natural lenses or following removal of the natural lenses.

  • Patent number: 6482229
    Abstract: An intraocular lens configured to be implanted in the cornea from the posterior aspect. The lens has an optic and a pair fixation members extending outward therefrom. One of the fixation members includes a single enlarged foot, while the other fixation member has two bifurcated feet. The fixation members are sized and shaped to fix within tunnels formed in the cornea. A method of the invention includes forming tunnels in the stroma layer of the cornea, and positioning the fixation members in the tunnels. The tunnels may be formed from outside or inside the cornea. The method may include inserting the folded intraocular lens into the anterior chamber, permitting the lens to unfold, inserting the fixation member with the enlarged foot in one of the tunnels, and bending the two bifurcated feet of the other fixation member together so as to fit within the other tunnel.

  • Patent number: 6475240
    Abstract: An intraocular lens having an optic and a plurality of fixation members coupled to the optic. The fixation members are adapted to be evenly circumferentially distributed about the anterior chamber to reduce the phenomenon of malshaping the iris, for example, pupil ovalling.

  • Patent number: 6228115
    Abstract: A refractive intraocular lens including an optic portion having an outer peripheral edge and three or four balanced haptic elements. Each haptic element is formed to have an inner portion and outer tip for supporting the optic portion in a patient's eye. The inner portion of each haptic element is permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a contact plate and a transition portion, which extends between the contact plate and the inner portion. Each haptic is formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is so designed to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.
