Abstract
The invention concerns an intraocular implant comprising a substantially circular optical part (10) and two curved haptic loops (12, 14) each with a first connecting end (12a, 14a) at the periphery of the optical part and a free second end (12b, 14b) intended to come to rest on the internal wall of the eye, characterized in that the optical part (10) and the haptic loops (12, 14) are made of the same flexible material, the elastic modulus thereof being in a range between 0.25 MPa and 1 MPa, and in that the width of each loop decreases from its connecting end to its free end such that the ratio between the bending moment variation and the inertia moment variation at two separate points (P1, P2) of the loop is substantially constant.
