发明名称 Accommodating multifocal intraocular lens
摘要 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.
