The Bonn Iris Hook is a specialized ophthalmic instrument commonly used in cataract surgery and other procedures requiring enhanced access to the lens capsule. Measuring 5 inches (12.5 cm) in length, it features a curved 3.0 mm hook designed to gently engage and retract the iris for improved surgical exposure. By providing controlled traction beneath the iris, the hook helps maintain adequate pupil expansion, reduces tissue slippage, and enhances procedural stability. Its ergonomic design allows for precise manipulation while minimizing surgeon fatigue, making the Bonn Iris Hook a valuable tool for achieving optimal visibility and control during delicate ophthalmic procedures.
