ABSTRACT:
An intraocular lens folding and inserting tool is formed of a folding clamp which bends the lens in half between spaced apart, resilient forceps tips which are temporarily secured within the folding clamp. The forceps is separated from the folding clamp for holding the folded lens and for inserting the folded lens into the anterior chamber of an eye through a small incision in the limbus of the eye. The folding clamp includes a U-shaped channel having side walls, a base and an open side, within which channel a lens is positioned. The forceps tips are secured in the channel between the side walls and between the lens and the channel base. A clamp pressure member engages and presses the center line of the lens towards the channel base for folding the lens in half between the tips. The forceps tips, which are made of axially elongated, resilient wire loops, are moved towards each other for resiliently holding the folded lens and for inserting the folded lens through the incision into the chamber where the folded lens is released.
