[Spurred iris hook for implanting posterior chamber lenses of the Kratz, Sinskey and Simcoe types]

The iris hook used for posterior chamber implants (e.g., the Kratz, Sinskey and Simcoe types) has a slight spur at its end. The spur catches the upper loop of the rotating lens during the implantation maneuver and forces it to slide behind the iris. If the spurred hook, retracting the pupil upward, is rotated about 10-15 degrees to the right, it guides the loop more safely and more gently into the posterior chamber. The spur prevents the loop from jerking over the iris hook and back into the anterior chamber.
