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.
