  • Patent number: 10524898
    Abstract: An improved self-centering phakic refractive lens is disclosed. The lens floats freely in the posterior chamber of the eye and corrects vision of the patient but also prevents buildup of intraocular pressure, cataract induction and iris pigment dispersion. The lens comprises an optical body, haptic members which extend outward from the optical body, and a small hole in the approximate center of the optical body for the purpose of allowing aqueous humor to flow through that hole. The lens is designed such that its posterior surface conforms to the shape of the anterior surface of the patient's natural crystalline lens.

  • Publication number: 20050033308
    Abstract: The present invention is a device for rolling, storing and inserting into an eye an extremely thin intraocular lens (IOL). The device performs as a roller and injector. Also disclosed herein are methods of using the lens rolling device. The chamber for rolling the intraocular lens includes curved walls, a hollow chamber, and a funnel for receiving a plunger, and a port for extruding a rolled lens. The IOL is effectively rolled by engaging the two parts of the rolling device. After rolling, the lens is ejected from the device through a cannula and into an eye.
