ABSTRACT:
An apparatus and method for delivering radiant energy beams onto the cornea of an eye to ablate the cornea in a radial slot or lenticular pattern and thereby modify its curvature and refractive power. The apparatus includes an array of central reflectors and an assembly of peripheral reflectors. Each central reflector is associated with a respective peripheral reflector so that a beam reflected by the central reflector is intercepted by its associated peripheral reflector and is again reflected to precisely incise the cornea. In a modified embodiment, the assembly of peripheral reflectors and the array of central reflectors rotate to permit lathing of the cornea. Each peripheral reflector has a curved reflective surface to provide a line focus on the cornea.
