Abstract
The invention concerns a monobloc intraocular lens made of a flexible material comprising a central optic part (1) and a haptic part (4) including two loops (5) in contact with an internal wall of the eye and, for each contact loop (5), two elements (10, 10′) to be linked with the optic part (1), the lens having a symmetry with respect to two perpendicular axes (6, 8), the external surface (9) of each contact loop (5) having a convex-shaped curve defining an apex (S), and two end points (E, E′). The circle (Ca) passing through the apex (S) and the two end points (E, E′) has a diameter &phgr;a greater than or equal to the mean diameter &phgr;m of the ocular housing, and less than &phgr;m+1.5 mm. The apices (S) are separated from each other by a distance D>&phgr;a and the linking elements (10, 10′) are adapted so as to be deformable in flexion in the principal plane (3) of the lens.
