  • Publication number: 20110054441
    Abstract: Methods of treating disorders of the eye are disclosed. One or more substances are injected into the vitreous humor of the eye using a syringe. A needle of the syringe is inserted into the eye such that the tip of the needle is positioned inferior to the visual axis. The needle of the syringe is inserted into the eye at an injection point that is located from 3 mm to 5 mm posterior to the limbus of the eye. The tip of the needle is positioned at a depth from 1 mm to 10 mm from the retina of the eye at the injection point.

  • Patent number: 6554860
    Abstract: A refractive anterior chamber iris fixated intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two, three or four balanced haptic elements. Each haptic element is of a relatively narrow arch-like form. Each haptic element is also manufactured to have an inner portion and an outer portion 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 fixation clamp on the outer portion thereof and a central portion located between the outer portion and the inner portion.

  • Patent number: 6398809
    Abstract: A refractive anterior chamber intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably three or four haptic elements. Each haptic element is of like form. Each haptic element is also manufactured to have an inner portion and an outer portion for supporting the optic portion in a patient's eye. The inner portion of each haptic element is preferably permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a contact button and a central portion located between the contact button 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.

  • Patent number: 5627162
    Abstract: The present invention relates to methods to control undesired cell proliferation of remnant cells following surgery, by applying an effective amount of at least one proteoglycan-type substrate adhesion molecule (SAM) to the site of surgery. SAMs, in particular chondroitin sulfate, hyaluronic acid, and non-toxic, pharmaceutically acceptable salts thereof, alone or in a composition form, are typically used to prevent or inhibit growth of lens-related cells in a lens capsule after surgical removal of the lens, or to prevent proliferative vitreoretinopathy following retinal reattachment procedure performed with or without vitrectomy.
