Jameson, Von Graefe, and Stevens are what type of instruments?

Jameson, Von Graefe, and Stevens are classified as muscle hooks, which are specialized surgical instruments used primarily in ophthalmic procedures. Muscle hooks play a vital role in ocular surgeries by allowing surgeons to manipulate and retract the extraocular muscles without causing damage to the surrounding tissues. Each of these instruments has a specific design tailored for accessing and securing muscles during various types of eye surgeries.

For instance, the Jameson hook is designed with a gentle curve that aids in the retraction of the lateral rectus muscle, while the Von Graefe hook is often utilized for engaging the superior rectus, allowing for precise muscle handling. The Stevens hook, with its unique shape, provides excellent access to specific muscles in the orbital area. Their effectiveness in maintaining visibility and the correct surgical field while protecting delicate ocular structures underscores why they are essential tools in the ophthalmic surgical toolkit.
