Abstract

This invention is a technique for laser sculpting a predetermined shape on a n exposed corneal surface (6) by ablating a sequence of consistently curved craters (16a, 16b, 16c, 16d) with individual pulses of a laser beam (10). An initial laser beam energy pattern (14) is shaped by a laser beam shaping element (22) to make a consistently curved laser beam (12) energy pattern. T he consistently curved laser beam (12) ablates a consistently curved crater (16 ) in the surface (6) with a single pulse of the laser beam (10). A computer (2 6) controls the position of the laser beam (10), and scans the laser beam over the surface (6) to sculpt the predetermined shape in an ablation zone (18) o n the exposed surface. A sequence of partially overlapping craters (16a, 16b, 16c, 16d) are distributed over the ablation zone (18). In some embodiments diffractive optics (50) are used as a beam shaping element (33). In addition al embodiments, the consistently curved crater (16) is a uniformly curved spherical crater.
