Abstract
A method of aligning the visual axis of a patient's eye with the optical axis of a beam of laser radiation for shaping the cornea by ablation includes the steps of optically folding the optical axis of a visible light laser into the optical axis of the ablation laser, aligning the optical axis of the ablation laser and the visible light laser to be both parallel and concentric where they impinge on the cornea of the patient's eye, adjusting the relative position between the patient's eye and the beam of visible radiation until the patient observes a characteristic flare around a spot of visible light.
