Abstract: A posterior-chamber intraocular implant for correcting short-sightedness in a phakic eye. Comprises a substantially circular optical portion (30) consisting of a front dioptric surface (40) and a rear dioptric surface (42) and a haptic portion. The haptic portion includes two extensions (32, 34) joined to the edge of the optical portion, of which the ends are spaced apart by a distance greater than the diameter of a dilated pupil, and two portions (52, 54) for attachment, the front surface of each extension comprising a toroidal portion (44) joined to the front dioptric surface, the rear surface of each extension comprising a toroidal portion (46) forming portion engaging the lens circumference and connected to the rear dioptric surface and a connecting portion (48), the rear dioptric surface and the toroidal portions of the rear surfaces of said extensions defining a recess (50) for freely altering the curvature of the front lens surface.
