Gass hook
Titanium ophthalmic hook with a flattened blade and a perforation near the tip, designed to engage and elevate the extraocular rectus muscles.
How it is used
Used in scleral buckling surgery for rhegmatogenous retinal detachment repair: it isolates and elevates each rectus muscle so traction sutures can be passed beneath it and the encircling band guided under the muscle insertion without injuring adjacent tissue.
Clinical tip
The hole near the tip lets a traction suture be threaded directly through the hook, keeping the muscle secured while the band is positioned.
