  • Patent number: 5290293
    Abstract: An intraocular lens folder having a generally planar, open frame in the shape of a rounded "A" with a rimmed, open head at the top of the "A." The base of the "A" forms a pair of opposing legs or handles that join to form a hinge at the crotch where the handles attach to the head. The hinge allows the handles to be squeezed together and yet spring apart when released. Squeezing the handles causes the top edge of the head rim to compress and move toward the hinge. The open head contains a plurality of projections terminating in open, relieved jaws into which the IOL is placed. The location of the projections is such that when the handles are squeezed together and the rim moves toward the hinge, two of the jaws moves toward each other, causing the IOL to be folded in half.
