Scleral retraction forceps for anterior chamber lens implantation.

Abstract

One of the most troublesome steps in implanting anterior chamber lenses has been retracting the scleral lip adequately when inse rting the proximal feet of the implant. Some scleras are difficult to grasp with any presently known instrument. Some instruments do not grasp directly under the foot, which has obvious advantages as described b y Tennant. l The instrument in Figure 1 * has been designed as a modified Colibre forceps with the 2 x 2, 0.12 mm teeth pointing downward, 90° from the instrument jaws. This allows the surgeon to grasp the sclera directly under the foot to be implanted (Figure 2) and provides a finn grasp of the scleral lip. An unobstructed view of the foot insertion makes it easy to tell when the implant clears the edge of the wound.
