摘要:
Multi-component intraocular lens (1, 201, 301, 501, 601, 701) implantable in a human eye optical system, comprising the multi-component intraocular lens: a base component (20, 120, 220, 320, 420, 520, 620, 720) having a front surface (30, 32) intended to be turned towards a front side of the human eye and a rear surface (33) opposite the front surface in the direction of the thickness of the base component and intended to be turned towards a rear side of the human eye, the base component comprising a central portion (21, 121, 221, 321, 421, 521) and a haptic portion (22, 122, 222, 322, 422, 522, 55 , 722) extending from a circumferential side of the central portion away from the central portion, the base component further comprising a retaining member (26, 126, 228, 328, 426, 526, 626, 726) located at the periphery of the central portion and protruding on the front surface of the component base e, and a front component (10, 210, 310, 510, 610, 710) comprising an optical portion (11, 211, 311, 511, 611, 711) disposed in front of the front surface of the optical portion of the base component, the front component further comprising a fixing pin (12, 212, 312, 612, 712) extending from a circumferential side of the optical portion of the front component away from the optical portion and applying to the member of retention for joining the front component to the base component, in which the fixing pin of the front component comprises a resilient projection protruding from the optical portion beyond the retention member (26, 126, 228, 328, 426, 526, 626, 726), in which a portion of the resilient projection (12, 212, 312) is located in a position that does not overlap with respect to the haptic portion (22, 122, 222, 322, 422, 522, 55 , 722) of the base component in a circumferential direction nial around the optical portions, characterized in that the portion of the resilient projection has a rear surface (213) that is located rearwardly from a front surface (230) of the ha
