A refractive intraocular lens includes an optic portion having an outer peripheral edge and at least two haptic elements each having an inner portion and an outer end for supporting the optic portion in a patient's eye, the respective inner portions of the haptic elements being connected to the outer peripheral edge of the optic portion. Each haptic element includes at least one footplate on the outer end, and further includes a central portion extending between the footplate and the inner portion. The central portion of each haptic element has a greater resistance to bending in a plane generally parallel to an optical axis of the patient's eye than in a plane generally perpendicular to the optical axis. The optical portion and haptic elements are preferably formed of a foldable or compressible material. |
