Multiple beam laser sculpting system and method
First Claim
1. A method for sculpting a material to effect a predetermined change in shape, the method comprising:
- radiating a beam of an ablative energy;
absorbing the energy within a region of the material so as to ablate the region, the ablation having an edge; and
, shaping the ablation at a distance from the edge by blurring the edge.

Abstract
The invention improves the laser sculpting of a region of a material to a predetermined shape by improving the smoothness and accuracy of surfaces formed by the sculpting technique. The technique includes projecting plurality of partially overlapping beams toward the region. The invention includes blurring an edge of an ablation to smooth an internal portion of the ablation that is separate from the edge. The blurred edge may be formed by the partially overlapping beams. Using a computer controlled laser delivery system, the position and shape of the overlapping beams may be precisely controlled to sculpt the material to a desired shape according to a laser treatment table.

11. A method of sculpting a lens in a region of a cornea of an eye, the method comprising:
-
radiating a beam of an ablative energy by lasing a laser to produce a laser beam of the ablative energy, the beam comprising a multiplicity of laser beam pulses;
absorbing the energy within a region of the cornea so as to ablate the region, the ablation having an edge; and
,shaping the ablation at a distance from the edge by blurring an edge from a single pulse to smooth an internal portion of the ablation, the internal portion being surrounded by and separate from the blurred edge. - View Dependent Claims (12, 13, 14)
