ABSTRACT:
A posterior chamber capsular lens implant and apparatus for implantation of the lens are utilized in a surgical method following a capsulectomy to remove a cataract impaired natural lens. The lens implant has a plane surface and a convex surface. The entire lens is fitted within the capsule of the posterior chamber. Affixed opposite each other within and along the peripheral edge of the lens are a pair of plastic, kidney shaped loops. The method for implanting the lens provides the steps of forming a triangular capsulectomy, extracting the cortical lens matter and any posterior subcapsular plaque matter from the capsular bag, and then inserting the lens implant. The insertion is accomplished by utilizing a plastic sleeve apparatus in conjunction with an irrigating canula. The loops of the lens implant maintain a centralized location of the lens within the posterior chamber capsule thereby eliminating any need for fixating sutures within the eye itself.
