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.
用于后房型植入物的虹膜钩（例如克拉茨型、辛斯基型和西姆科型）在其末端有一个小刺。在植入操作过程中，这个小刺会钩住旋转晶状体的上袢，并迫使它滑到虹膜后面。如果带刺的钩子向上牵拉瞳孔并向右旋转约10 - 15度，它会更安全、更轻柔地引导晶状体袢进入后房。这个小刺可防止晶状体袢从虹膜钩上滑脱并回到前房。
