METHOD AND SYSTEM FOR ABLATION OF SURFACES WITH PARTIALLY RECOVERED AND COHERENT CURVATORY CRATERS |
abstract |
This invention is a technique for laser sculpting a predetermined shape on an 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. The 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 (26) 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) on 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 additional embodiments, the consistently curved crater (16) is a uniformly curved spherical crater. |
