  • Securing device for an intraocular lens
    Patent number: 4177526
    Abstract: An artificial lens is adapted to be implanted within the eye to replace the natural lens. A pair of arms projecting from the lens are held by a frangible thread such that the tips of the arms are spaced from but biased toward the peripheral portion of the lens. The lens is implanted immediately in front of the iris with the arms inserted behind the iris. After implanting of the lens, a laser beam is employed to break the thread. The arms then spring forwardly in a manner to firmly pinch the iris between their tips and the peripheral region of the lens.
