Abstract
A flexible biconvex lens for intra-capsular implantation in an intra-ocular lens capsule of a patient enables the lens refractive properties to be to altered by the transfer of forces from ciliary muscles of the patient to said the flexible biconvex lens. The flexible lens comprises a plurality of holes spaced at equal radial intervals around the periphery of the lens. The plurality of holes promote tissue ingrowths to secure the flexible biconvex lens to the intra-ocular lens capsule without requiring peripheral mechanical extensions, adhesives or mechanical fasteners to said flexible biconvex lens.
Claims10
A flexible lens for intra-capsular implantation in an intra-ocular lens capsule of a patient, the flexible lens comprising:
- a flexible biconvex lens defined by a biconvex posterior radius of curvature between about 4 millimeters to about 8 millimeters and a biconvex anterior radius of curvature between about 8 millimeters to about 11 millimeters;
- and,
- a plurality of holes within said flexible biconvex lens, spaced at approximately equal radial intervals around periphery of said flexible biconvex lens;
- wherein and said plurality of holes promote tissue ingrowths to secure said flexible biconvex lens to the intra-ocular lens capsule without requiring peripheral mechanical extensions, adhesives or mechanical fasteners to said flexible biconvex lens and enable transfer of forces from ciliary muscles of the patient to said flexible biconvex lens and thereby alter refractive properties of said flexible biconvex lens.
