Disclosed is an artifical lens adapted for implantation in the human eye and the method for implanting such lens. The lens (1) is of pliable material so that it may be folded or curled for insertion through a minimum length incision. It has a medial optic portion (2) having a posterior concave surface (2a) corresponding to the anterior surface (13c) of the natural lens (13) when the latter is in its flattest natural position and haptic portions (3, 4) for seating the lens in the eye such that the posterior concave surface of the medial optic portion of the artificial lens seats directly against the anterior surface of the natural lens of the eye which remains in and is not removed from the eye. The method according to the invention includes determining the shape of the anterior surface of the natural lens when the latter is in its flattest natural position, forming the posterior surface of the optic of the artificial lens such as to correspond substantially to that shape and seating the lens in the posterior chamber between the iris and the natural lens with the posterior concave surface of the artificial lens seated on the anterior convex surface of the natural lens.
