Abstract
The multi-plane corneal incision form of this invention includes a frame member in the shape of a segment of a hollow sphere that fits over a patient's cornea. The inner surface of the frame member includes a protuberance that distorts the cornea when the frame member is placed against the patient's cornea. The frame member also includes an aperture adjacent to the protuberance to allow a surgical blade to pass therethrough. By carefully configuring the protuberance and aligning the aperture, a physician can insert a surgical blade into the aperture and through the distorted cornea in a planar fashion that results in a multi-plane incision in the cornea once the frame member is removed from contact with the patient's cornea.
