ABSTRACT:
A lens implant for insertion in a human eye after an extra-capsular extraction includes a lens body of polymethyl methacrylate to which are attached first and second curved holding loops formed integrally with and projecting from the periphery of the lens. The loops are diametrically attached to the lens and the loops project from the lens along a curved path so that the pair of loops define generally an ellipse that symmetrically surrounds the lens body. Each loop terminates at a free end in a positiion near the point of attachment of the other loop. The free end of one loop and the point of attachment of the second loop are in a common quadrant of the ellipse, with the respective ellipse quadrant having a loop-free end and a point of attachment being also diagonally opposed. The free end of one loop and the point of attachment of the second loop are radially spaced by a measure of less than ninety degrees (90.degree.). The improved design provides a better geometric profile for surgical insertion in combination with improved flexibility characteristics.
