During intraocular lens implantation, what type of hook is used to rotate the IOL into place?

The Sinskey hook is specifically designed for manipulating intraocular lenses (IOLs) during cataract surgery and is particularly effective when it comes to rotating the IOL into its proper position within the capsular bag. Its unique design, which typically features a long, slender shaft with a hooked end, allows for precise movements and placements of the lens without disturbing the surrounding structures of the eye.

The other instruments, while useful in their own right, serve different purposes. A chopper is generally used to facilitate the separation of the lens during phacoemulsification. A capsule hook is meant for manipulating and stabilizing the lens capsule during surgery rather than rotating the lens itself. A lens holder assists with the grasping and handling of the IOL but does not have the ability to maneuver the lens into its final orientation as skillfully as a Sinskey hook does. Thus, the correct use of the Sinskey hook is crucial for the accurate placement of the IOL within the eye.
