Haptic Is Formed From Multiple Layers Patents (Class 623/6.5)
  • Patent number: 8585759
    Abstract: A device includes a plurality of ringlets connected together to form a ring having a longitudinal axis. Each ringlet includes a first element and a second element. The first and second elements each extend from a first end through a central portion to a second end. The first and second ends are disposed at radially outer positions with respect to the ring than the central portion. The central portion is longitudinally displaced from the first and second ends. The first and second elements are separated and spaced apart from each other at the central portions thereof and are joined together at the first ends thereof and the second ends thereof. The ringlets are connected together such that the first ends of the elements of one ringlet are connected to the second ends of the elements of an adjacent ringlet.

  • Publication number: 20120029632
    Abstract: An intraocular lens assembly for implantation in the posterior chamber of an eye has anchor portions with teeth rigid enough to penetrate the scleral wall of an eye. A method for implanting the lens includes the steps of: introducing the first haptic portion with a first anchor portion that includes a plurality of teeth projecting therefrom, into the posterior chamber of the eye until said teeth are anchored in the scleral wall at a desired location; and moving a second haptic portion with a plurality of teeth projecting therefrom, until said teeth are anchored in the scleral wall on the opposite side of the lens from the first anchor portion.

  • Patent number: 6942695
    Abstract: Intraocular lenses and methods producing the same are provided. The intraocular lens includes an optic and a haptic that are integrally formed together. The haptic has a polyimide coating. The polyimide coating promotes fibrosis in the surrounding eye tissue to enhance the anchoring of the IOL after it is implanted in an eye.

  • Publication number: 20030187505
    Abstract: An accommodating intraocular lens for implantation within the capsular bag of a human eye from which the natural lens matrix has been removed. The intraocular lens includes an optic portion for providing vision corrective power and a pair of haptics having relatively flexible portions and relatively inflexible portions reinforced with a mesh-like material such that additional stiffness is imparted to the haptic material without increasing the thickness of the haptic or changing its shape.

  • Publication number: 20030045932
    Abstract: An iris-supported intraocular lens having an optic portion and a plurality of fixation members coupled thereto. Each fixation member has a pair of pincer arms that separate outward of the optic and converge toward one another at aligned end tips. One or both of the end tips are covered with a soft sleeve or cap. The IOL is fixed in the anterior chamber of the eye by pinching the iris tissue between the end tips of each pair of pincer arms. The soft sleeves eliminate damage to the iris tissue.
