Abstract
The invention concerns a monobloc intraocular lens made of a flexible material comprising a central optic part ( ) and a haptic part ( ) including two loops ( ) in contact with an internal wall of the eye and, for each contact loop ( ), two elements ( ′) to be linked with the optic part ( ), the lens having a symmetry with respect to two perpendicular axes ( ), the external surface ( ) of each contact loop ( ) 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 ( ′) are adapted so as to be deformable in flexion in the principal plane ( ) of the lens.
