Abstract: An accommodating intraocular lens is provided and includes an optic; a haptic having an opening formed therein; and a flexible membrane having a first peripheral edge and a second peripheral edge. The flexible membrane has an opening extending therethrough from the first peripheral edge to the second peripheral edge, wherein the first peripheral edge attaches to the optic and the second peripheral edge attaches to the haptic so that the optic is axially aligned with the opening. The flexible membrane is formed of a memory type material so that when the ciliary muscle constricts, the optic moves in an anterior direction and the flexible membrane deforms from a first position to permit the optic to move. Relaxation of the ciliary muscle causes the optic to move in a posterior direction, resulting in both the optic and flexible membrane toward the first position.

Abstract: A high-myopia intraocular lens (IOL) for anterior-chamber implantation is constructed as a single, integral unit with an optic portion in the shape of a substantially circular concave lens, an annular flange portion extending radially outwards from the circumference of the optic portion, and haptic elements for fixating the IOL in its implanted position. The annular flange is substantially impervious to light and has an outside diameter at least as large as the aperture diameter of a dilated pupil of the eye. The circumferential surface of the optic portion is substantially light-impervious as well as non-reflective. The IOL is at least in part foldable to facilitate surgical implantation in the eye through a small incision.

Abstract: An intraocular lens is provided and includes a deformable optic; a pair of support posts spaced circumferentially about the optic and extending outwardly therefrom; and a pair of retaining elements for securing the lens portion within an anterior chamber of the eye by grasping a portion of an anterior surface of iris tissue. Each retaining element has flexible first and second pincer tips that are normally in an abutting or a close abutting relationship when the retaining element is in a closed position. Each retaining element is secured to the anterior surface by opening the first and second pincer tips and pinching the anterior surface of the iris tissue. The optic is coupled to the retaining elements by disposing the support posts within openings or slots that are defined in the retaining elements. The coupling between the posts and the retaining elements is such that the optic is not only securely held within the anterior chamber but also is easily removable and adjustable.

Abstract: A supplemental lens assembly for attachment to the position fixation means of a primary intraocular lens to change its optical characteristics. The assembly comprises a supplemental lens body with at least one connecting member extending from it and adapted for attachment to the position fixation means of the primary lens.
