A SMALL functional iris retractor has been developed which has particular advantage during cataract extraction with sliding techniques, with α-chymotrypsin, and with cryosurgical extraction. This instrument facilitates retraction of the superior (12 o'clock) position of the iris for grasping of the lens with the sliding technique. It also allows retraction of the iris to prevent its freezing coincident with the application of the cryosurgical tip to the lens. Further, it provides precise retraction of the iris over the equator of the lens during the lens delivery. The retractor may also be used for direct zonular stripping and lysis of posterior pupillary synechiae.
The iris retractor is made from stainless steel. The design is that of a small disc attached to a rod whose tapered, functional end has been angled approximately 10 degrees. The direction and amount of the peripheral angle of the retractor may be individualized by the surgeon in
