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.
