Abstract
A toric axis marker has a handle, a coaxial tip, a head upon the tip, a dial axially above the head, and a marker head with two blades connecting to the dial. The dial and blades rotate simultaneously and concentrically upon the head. The head and its components have a central aperture for a surgeon to use in positioning the marker relative to the center of an eye. The marker head has its two blades upon a common diameter. The dial has two symmetric arcuate windows that reveal an angle scale. The marker body has an inwardly offset angle to the handle. Each blade has a blunt edge outwardly from the marker head and a slightly curved shape that conforms to the shape of an eyeball, proximate the cornea. With the blades positioned, a surgeon marks the cornea with an ink for incision locations.
