ABSTRACT:
An apparatus and method for implantation of intraocular lenses includes a resilient tubular sling which is positionable over parallel working ends of a crossover forceps. The sling allows an intraocular lens to be folded or curled up therein and held in that folded up position with the forceps tips in a closed position. The forceps presents a narror-in-cross-section moving crossover point behind the tips to allow the forceps tips to be inserted through a small incision in the eye, and then open to release the lens once within the eye. By maintaining the crossover point at the small incision, the forceps can release the lens even though it requires the opening of the forceps tips to a position wider than the incision in the eye. The resilient sling holds the folded lens compactly during movement through the small incision, and assists in urging a controlled release of the lens into the eye. The sling also avoids having to handle the lens with the forceps tips prevents damage to the lens.
