Abstract
A corneal incision device of the present invention includes a surgical blade and a frame having an inner surface with a configuration that is generally in the shape of a ring-like segment of a hollow sphere. The frame has an aperture therein to allow the surgical blade to be inserted through the frame beyond the inner surface. The aperture is sized and shaped to allow movement of the surgical blade in one axis. The device may have a protuberance affixed to the inner surface of the frame adjacent to the aperture disposed to distort a surface of a patient's eye when the device is selectively positioned on the eye by a practitioner. The device has provisions for holding, advancing and withdrawing the surgical blade through the aperture, disposed on the frame. The device is releasably retained on the patient's eye by fixation elements disposed on the inner surface of the frame. There is a handle affixed to the frame to facilitate the practitioner's manipulation of device.
