  • Patent number: 8603166
    Abstract: Disclosed is an intraocular lens assembly provided inside a capsular sac. The intraocular lens assembly according to one embodiment of the present invention includes an intraocular lens and an intraocular lens supporter, and therefore the intraocular lens assembly may be useful to transfer a force to the intraocular lens, inserted inwardly into the capsular sac, to allow the intraocular lens to move like a natural eye lens, the force being generated from the ciliaris muscle and transferred through the zonule of Zinn and the capsular sac.

  • Patent number: 8357196
    Abstract: An intraocular lens for providing vision to an animal or human subject has anterior and posterior sides. The lens includes an optic body, one or more haptics, and one or more marks. Each mark has four or more features disposed along an imaginary line when viewed from the anterior side and/or the posterior side. The mark(s) may be used as an aid in angularly aligning the lens during use.

  • Publication number: 20080269888
    Abstract: A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.

  • Patent number: 7326246
    Abstract: An intraocular lens (IOL) for insertion in a capsular bag of an eye includes an optic for focusing light and a movement assembly coupled to the optic. The movement assembly is adapted to cooperate with the capsular bag to effect accommodating movement of the optic. The movement assembly includes one or more elongated fixation members coupled to a periphery of the optic and adapted to convert radial movement of the capsular bag to axial movement of the optic. The fixation members extend spirally at least half-way around the optic. Angled transition sections may be provided between each fixation member and the optic periphery. The anterior and posterior edges of the optic periphery may have relatively sharp angles to reduce epithelial cell growth.

  • Patent number: 7090888
    Abstract: A method of making an ophthalmological implant by applying a layer of pharmaceutical agent and an overlying layer of a bioerodible material, a biodegradable material, a bloavailable material or a mixture thereof, the overlying layer having variable thickness and being dimensioned for prolonged release of the pharmaceutical agent from the implant as the overlying layer degrades.

  • Patent number: 6699284
    Abstract: An intraocular lens to be placed in an anterior chamber of a patient's eye is disclosed. The intraocular lens includes a lens part with a predetermined refractive power, including a front lens surface facing toward a cornea side and a back lens surface facing toward a fundus side when the intraocular lens is placed in the anterior chamber, a support part provided in an edge of the lens part and with an end positioned opposite to the edge, the end being insertable into an iris to penetrate to a fundus side thereof and back to a cornea side thereof to hold the lens part in the anterior chamber, and a hook provided in the end of the support part for preventing the support part from coming off the iris.

  • Patent number: 6692525
    Abstract: An intraocular lens for implantation in an eye comprising an optic configured so that the optic can be deformed to permit the intraocular lens to be passed through an incision into the eye. A peripheral zone circumscribes the optical zone of the optic and one or more fixation members coupled to the peripheral zone and extending outwardly from the peripheral zone to retain the optic in the eye are provided. In one embodiment the fixation member or members are located so that the optical zone is free of such member or members. The peripheral zone preferably has a maximum axial thickness which is larger than the maximum axial thickness of the periphery of the optical zone.

  • Publication number: 20030050695
    Abstract: The present invention is to provide an intraocular lens that may accommodate automatically, including a central optic having an anterior optic connected with the stroke cylinder, a posterior optic connected with the outer core which is connected with the stroke cylinder, thereby enclosing the central optic in an inner periphery. Thus, by change of the inclined angle of the user, or by variation of the external magnetic field, the push force that is exerted on the central optic of the intraocular lens may be regulated, so as to actively control the position of the central optic of the intraocular lens, so that the user may actively control and regulate the refractive power of the eyeball that is implanted with the intraocular lens.

  • Patent number: 6451056
    Abstract: An intraocular lens provides substantially increased depth of focus for accurate near and far vision with an optic much thinner than a natural lens, and the lens being rigid, vaulted posteriorly and adapted for posterior positioning in the capsular bag. The optic is positioned substantially farther from the cornea than a natural lens, so that a cone of light exiting the optic to impinge upon the retina is much smaller than a cone of light from a natural lens. Typically, the optic may be about 1.0 mm thick and its distance from the cornea 7.0-8.0 mm.

  • Patent number: 6425917
    Abstract: A film frame for an IOL has been developed which has the advantages of being lightweight, non-irritating, easily surgically implanted, aesthetically pleasing, and containing plate haptics. This IOL works in the anterior or posterior chamber of the eye for phakic or aphakic lenses and especially in the anterior chamber for phakic refractive lenses where thinner is better and long-term stability is required. This deformable IOL frame is a haptic system based on a high modulus harder material shaped skeletal frame or plate haptic assembled with low modulus softer elastomeric hinged zones. The rigid frame or haptic in combination with the soft hinges will ensure that the lens is ideally situated in the anterior chamber angle of the eye. Additionally, the soft elastomer can be extended to provide for a softer atraumatic contact point or ‘toe’ in the eye tissue.
