Abstract:
1. An accommodative intraocular lens, comprising an optical arrangement and haptics, the lens being adapted for variable focusing by movement or deformation of at least one part of the optical arrangement by at least one of the haptics, wherein the haptics comprise a part adapted to transfer a movement from the ciliary mass to the optical arrangement, wherein the haptics comprise at least two springs adapted to transfer a movement from the ciliary mass to the optical arrangement, wherein the haptics comprise a coupling component which is adapted to contact the ciliary mass directly, wherein the haptics comprise a flange adapted for positioning in the sulcus, wherein the haptics further comprise a rim, said rim comprising a protruding part that is adapted to be in contact with the ciliary mass, wherein said rim is positioned between an anterior optical element and said flange, and each spring extends between said rim and a posterior optical element, wherein the springs are adapted to convey the movement of the ciliary mass to at least one optical element of the optical arrangement, to vary defocus by shift of said optical element, so that contraction of the ciliary mass leads to an axial movement of the posterior optical element in the direction of the optical axis, and wherein the axial movement of the posterior optical element corresponds to a change in diameter of the anterior optical element.
