    Abstract: Apparatus for being held by the human hand for performing refractive keratectomy on the eye of a patient by the use of radio frequency energy from a radio frequency generator. An elongate probe has proximal and distal extremities. The proximal extremity is sized to be grasped by a human hand. The elongate probe has a length so that the distal extremity can be held in close proximity to the cornea while the proximal extremity is held by the human hand. An energy delivery member is carried by the distal extremity. Conductors are carried by the elongate probe for conducting radio frequency from the generator to the energy delivery member. A dispersive member is carried by the energy delivery member for dispersing the radio frequency energy from the energy delivery member and applies the energy to the cornea to remove a portion of said cornea in order to reshape the cornea and improve vision.
