Abstract
A laser beam delivery apparatus and a method for smoothly and uniformly ablating tissue, e.g., for reshaping a cornea of an eye, even in the face of real-world conditions such as a moving eye. The method includes defining a plurality of scan lines in an ablation zone on the tissue and defining a plurality of laser beam ablation points along each of the scan lines. An ablating laser beam is scanned along a series of non-adjacent scan lines of the plurality of scan lines and tissue is intermittently ablated at non-adjacent ones of the laser beam ablation points on each non-adjacent scan line of the series of non-adjacent scan lines.
