  • Patent number: 5843188
    Abstract: A method of providing an artificial lens inserted into the eye between the iris and the natural lens zone, there being eye ciliary muscles located peripherally of the zone, that includes providing the artificial lens to be compliant and to have anterior and posterior surfaces, and haptics extending away from the periphery of the artificial lens; and inserting the artificial lens to extend into position between the iris and the zone, and to cause the haptics to extend into adjacency to the ciliary muscles, and; allowing the haptics to adhere to the ciliary muscles; whereby subsequent movement of the ciliary muscles causes movement of the haptics transmitted to effect bodily movement of the lens in posterior and anterior directions to change the angularity of refraction of light passing through the lens toward the eye retina.

  • Patent number: 5776139
    Abstract: An apparatus used for intraocular implantation of a plastic lens in an internal eye zone, as via a surgical incision in the corneo-scleral limbus, which includes two elongated lever arms, each of which has a distal first zone for gripping the lens, a second pivot zone rearward of the distal zone, and a third manual pressure receiving zone; the arms coupled together rearwardly of the third zones so that the first distal zones are yieldably urged toward one another by the arms to grip the lens therebetween for intraocular implantation; the second pivot zones configured to pivot in interengagement in response to controllable manual squeezing force exertion on the third zones, thereby to cause the first zones to relatively separate, freeing the lens for release in the internal eye zone.

  • Patent number: 5578081
    Abstract: An artificial lens unit insertable into a capsular eye lens zone from which a natural lens has been removed, comprising the lens having a light refracting optical portion defining an axis, and consisting of plastic; the unit including haptics for positioning the lens in the capsular zone, the haptics extending at angles relative to a plane normal to the axis and passing through the lens; and the haptics' angles characterized in that the lens is displaced in the direction of the axis by the haptics in response to eye muscle constriction of the periphery of the capsular zone toward the axis.

  • Patent number: 5571113
    Abstract: A surgical apparatus useful for eye surgery, wherein an incision is made in the eye corneo-scleral tissue, and via which a plastic lens is to be introduced into an eye lens zone in a capsule from which a natural lens has been removed, the lens having haptic structure including haptics attached thereto, the apparatus comprising an elongated probe having an axis and at least three discrete tips projecting at one end of the probe, the tips spaced about the axis to receive the lens for probe manipulation and positioning of the haptic and lens in the capsule; and a tube receiving the probe, with the tips positioned to displace the haptics and lens, in the tube.

  • Patent number: 5425759
    Abstract: A foldable plastic lens insertible into the eye lens zone from which a natural lens has been removed comprising the plastic lens having a light passing intermediate and bead-like optical portion, and two oppositely extending haptics; the lens also having two opposed peripheral segments characterized as light blocking; and the segments having substantially reduced thickness relative to the thickness or thicknesses of the main extent of the intermediate optical portion. Reinforcement strands are typically incorporated with the segments, and may assist in anchoring the haptics.

  • Patent number: 5395378
    Abstract: Surgical apparatus useful for eye surgery, wherein an incision is made in the eye corneo-scleral tissue, and via which a plastic lens is to be introduced into an eye lens zone in a capsule from which a natural lens has been removed, the lens having haptic structure including haptics attached thereto comprising a surgical forceps having two longitudinally elongated, laterally spaced arms and two blades, the arms extending in parallel relation, each blade integral with an arm at the forward end thereof, each blade being blunt at the forward end thereof; whereby the forceps may be displaced to controllably receive a haptic or lens, or both, between the blades and to controllably displace the haptic or lens, or both, for positioning the haptics and lens in the capsule; and a tube receiving the forceps, with the blades positioned to engage and displace the haptic and lens, in the tube.

  • Patent number: 5292324
    Abstract: An intraocular lens implantation forceps, including first and second arms having handles and lens engagement blades; the blades extending generally longitudinally in laterally spaced relation and at opposite sides of a plane bisecting the forceps. The arms have primary and secondary arm sections extending between the handles and blades. The arms primary sections extend in cross-over relation to define a cross-over locus, when the blades are in open position; the secondary arm sections extending generally longitudinally in substantially parallel relation and positioned such that when the blades are in the closed positions one secondary arm section extends at one side of the plane and the other secondary arm section extends at the other side of the plane, and when the blades are in the open positions the one secondary arm section extends at the other side of the plane and the other secondary arm section extends at the one side of the plane.
