About the Gill Corneal Knife
The Gill corneal knife is a small ophthalmic hand instrument offered by eye-instrument makers such as Katena and Bausch & Lomb in straight and curved versions. In the US device registry it appears mostly under the general ophthalmic knife category: a hand-held instrument with a single-edged blade at the tip and a handle, used to make precise incisions in the eye and surrounding tissues.
One maker files it instead under "eye spud", a category for instruments with a thin concave, round-nosed blade used to lift material from the eye surface. This suggests a rounded blade rather than a pointed one, but the reviewed sources give no fuller description.
Blade shape and curvature should be checked against the individual catalogue entry.
