I claim:
1. An apparatus for intraocular implantation of a plastic lens in the eye lens zone from which a natural lens has been removed via surgical incision in the corneoscleral limbus, said apparatus comprising
- a) a surgical forceps having two arms and blades projecting beyond portions of said arms defining a cross-over locus, the blades clamping the plastic lens to be implanted,
- b) said blades including first and second spaced blades carried by one arm, and a third blade carried by the other arm, providing three-point stable support for the lens,
- c) said blades extending in horizontal parallel planes, wherein each of said first, second and third blades has a longitudinal axis, a lateral width of each of said first, second and third blades with respect to said longitudinal axis being substantially equal, said arms extending upwardly and away from the blades in generally the same direction from said cross-over locus, said one arm extending above the other arm, said first and second blades extending in the same horizontal primary plane which is spaced below the horizontal secondary plane in which said third blade extends.
