ABSTRACT:
An ablation apparatus for ablating an object to a uniform depth by a laser beam. The laser may be an excimer laser, having non-uniform beam intensity of Gaussian distribution and like. Therefore the laser beam is scanned to the non-uniform intensity distribution and irradiated on the surface of the objection, whereby uniform depth of ablation is achieved. The apparatus is preferably applied to the operation of the cornea.
