Abstract
A lens implantation instrument includes first and second prongs connected together in a forceps-like configuration that is adapted to be grasped in the hand of a user for purposes of holding an intraocular lens to be implanted in an eye. The first prong has a distal end portion that defines a trough extending distally, the trough having a size and shape adapted to receive at least a portion of the optic of the lens with the optic in a folded configuration, and the second prong has a distal end portion that extends generally parallel to the trough, the distal end portion of the second prong having a size and shape adapted to fit at least partially into the trough. The first and second prongs are connected to enable the user to move the distal end portions relative to one another between an opened position in which the distal end portions are spaced apart sufficiently to enable placement of the lens between the distal end portions and a closed position in which the distal end portion of the second prong retains at least a portion of the lens in the trough with the lens in a folded configuration. The first and second prongs are also connected to enable the user to retract the distal e…
