Abstract
An intraocular lens to be implanted into the capsular bag after ablation of the crystalline lens includes a central optical portion and a haptic portion including haptic members arranged on the periphery of the optical part and for positioning the intraocular lens in the capsular bag. On the one hand, the posterior surface of the optical portion includes a sharp ridge at the peripheral edge and, on the other hand, the posterior surface of the haptic members includes a proximal area in the vicinity of the peripheral edge of the optical portion, each proximal area including at least one tooth extending substantially along the entire width of each haptic member, the tooth or teeth having a sharp edge that becomes serrated in the posterior capsule in order to limit the migration of the epithelial cells of the haptic members towards the optical portion.
