ABSTRACT:
Corrective intraocular lens for use with an intact natural eye lens, by insertion through an incision into the eye and implantation therein in spaced relation to the natural lens, including a lens body having a pair of opposed haptics constituting a first insertable leading haptic and a last insertable trrailing haptic, each outwardly terminating in a transverse edge having a pair of laterally spaced apart and outwardly projecting contact lobes for engaging an adjacent eye tissue portion at a corresponding pair of spaced apart tissue points, the trailing haptic transverse edge having a 2-3 mm length, and the leading haptic transverse edge having a length larger than 2-3 mm and preferably about as large as the lens body diameter, such that the 2-3 mm length transverse edge of the last inserted haptic may be passed inwardly of the incision under minimum deflection of the intraocular lens and minimum risk of contact with the natural lens by the intraocular lens during implantation.
