ABSTRACT:
An intraocular implant unit having a lens (10) with a first limb (11) and a second limb (12) integral therewith and extending outward radially from opposite margins thereof. A long arcuate rim (13) is centered on the end of the first limb (11) and a short arcuate rim (14) is centered on said second limb (12) wherein the rims (13, 14) and limbs (11, 12) are substantially less in lateral dimension than the diameter of the lens (10) for minimizing the weight of the implant unit while assuring positive fixation.
