  • Publication number: 20100094412
    Abstract: An improved multifocal design for an ocular implant is provided. This ocular implant can include an accommodating intraocular lens (IOL) and a number of haptics. The accommodating IOL includes a liquid suspended between two optically transparent plates or membranes to form a pressure lens that passes optical energy. The haptics mechanically couple to the IOL in order to position and secure the IOL within the eye. The IOL achieves accommodation by using the eye's ciliary muscles to vary the surface curvature of the liquid. The liquid may have a high surface tension and be surrounded by phobic liquid. Pressure from the ciliary muscles causes fluid to be added from or withdrawn to a reservoir. Increasing/decreasing the internal pressure of the liquid changes the angle (curvature) of the surface thus changing the optical properties of the lens. When the pressure is released the liquid returns to the reservoir. The whole system may be sealed off from the interior of the eye by a membrane/transparent lens.

The intraocular lens has: a lens unit including a convex lens, a hard magnetic material provided at the periphery portion of the convex lens, and a guidance member provided at the periphery portion of the lens unit; a cylinder-shaped flame unit for storing the lens unit therein, including a helical guidance groove formed on the inner surface thereof for meshing with a top of the guidance member of the lens unit and for carrying the lens unit along with the optical axis of the lens unit while rotating; and a pair of loop units for fixing the a cylinder-shaped flame unit storing the intraocular lens. The lens unit rotates by an application of magnetic force from outside thereby to move to a portion where the fine image formation of the desired object can be obtained.

  • Publication number: 20020055776
    Abstract: Featured is an injectable intraocular lens system including an insertion and injection device and an injectable intraocular lens. In its broadest aspects, the injectable intraocular lens is a deflated flexible bag that is disposed within the insertion and injection device prior to insertion into the eye. In use a portion of the insertion and injection device is inserted into the eye and the flexible bag is deployed out from an aperture in the inserted portion into the eye. Following deployment, the insertion and injection device injects an optical medium, such as a liquid, into the interior of the flexible bag, thereby inflating the bag. In an illustrative embodiment, the amount of medium being injected is selected so that the inflated bag provides the desired corrective power to the intraocular lens so formed.

  • Patent number: 6299641
    Abstract: An intraocular lens (38) having focusing capabilities permitting focusing movement of the lens (38) in response to normal ciliary muscle movement incident to changes in the distance between the eye and an object under observation is provided. The lens (38) is designed for surgical implantation within the capsule (22) of an eye (10) and includes an optic (40) and a resilient body (46) which cooperate to form a discoid shaped lens (38) that generally conforms to the shape of the natural capsule (22). When distant objects are viewed, the ciliary body (32) is retracted and the capsule (22) flattens, thus causing the lens (38) to likewise flatten, moving the optic (40) posteriorly, closer to the fovea (26). When viewing near objects, the ciliary body (32) contracts, causing the capsule (22) and thus the lens (38) to expand to their original shape, shifting the optic (40) anteriorly, away from the fovea (26).
