Abstract
A scanning ablation laser is disclosed having a fundamental output from a mirrored facet in the ultraviolet range, the fundamental ultraviolet output having an energy level of no greater than 10 mJ/pulse on the corneal surface. A controller controls the laser and scanning mechanism to deliver a focused and scanned pulsed output laser beam in a predetermined overlapping pattern onto a plurality of positions on a corneal surface to photoablate at least one layer of corneal tissue such that an overlap among respective ablating spots of individual pulses of the scanned pulsed output laser beam on a single ablation layer is at least 50%. The scanning mechanism may locate laser beam pulses in a random pattern on the corneal surface. In one embodiment, a beam splitter splits the pulsed output laser beam into a plurality of laser beams.
