ABSTRACT:
A cutting instrument for severing a thin layer of corneal tissue from the surface of the eye, preferably leaving a flap. The cutting instrument includes a body portion that forces the surface of the eye against an applanating surface through a vacuum. A blade with a cutting edge not perpendicular to the direction of travel is then urged across the surface of the eye, severing a thin layer of corneal tissue. The blade can then be retracted, the instrument removed, leaving a flap of corneal tissue suitable for surgical procedures to modify corneal curvature.
