Abstract:
A method of generating a treatment table for ablating tissue using a scanning laser beam for generating scanning spots over a treatment region larger in area tan the scanning spots, the method comprising:providing a target function representing a desired lens profile for ablating the tissue by scanning spots of the laser beam on the tissue to achieve a desired removal of the tissue by ablating the tissue according to the desired lens profile represented by the target function; providing a user-specified basis function representing a treatment profile produced by scanning with overlapping scanning spots of the laser beam to be centered at a plurality of scanning spot locations on the tissue in a user-specified treatment pattern; and fitting the target function with the user-specified basis function to obtain a treatment table including scanning spot locations and characteristics for the overlapping scanning spots of the laser beam, such that an ablation employing the user-specified basis function according to the scanning spot locations and characteristics of the treatment table will substantially achieve the desired removal of the tissue as represented by the target function.
