Intraocular implant and an artificial lens device

An accommodating artificial lens device comprising an accommodating intraocular implant (100) comprising a single piece of elastically deformable material constituting a central lens (1) and at least two haptic portions (2, 4) in the form of radial arms, wherein a free end of each radial arm (2, 4) is fitted with a shoe (6, 7) of substantially toroidal outside surface, the connection between each shoe (6, 7) and the corresponding arm (2, 4) being of a hinge type situated in the vicinity of a posterior edge of the shoe (6, 7) and being formed by a first thin portion (2d, 4d) of the arm, while the connection between each said arm and the lens is of the hinge type implemented at an anterior surface of the lens by a second likewise thin portion (2c, 4c) of the arm, a plane (P1) containing the first thin portions being situated behind a plane (P2) containing the second thin portions, the accommodating artificial lens device further comprising an elastically deformable element (120, 130) separate from the implant, the element having at least a radially-deformable gutter-shaped peripheral portion whose diameter at a bottom of the gutter in a rest state is no greater than an outside diameter of the implant measured across outside faces of the shoe (110) when the implant is in the rest state, wherein the elastically deformable element (130) is restricted to a gutter-shaped ring having a posterior lip (133b) which undulates in festoons.
