Abstract
A look-up table for use in determining an energy parameter for photodisrupting ocular tissue with a laser is generated by determining a plurality of individual spot size distributions, wherein each of the plurality of individual spot size distributions is based on a different set of simulated data and includes an expected spot size of a laser focus at each of a plurality of locations within a modeled target volume of ocular tissue. The plurality of individual spot size distributions are combined to obtain a final spot size distribution that includes a final expected spot size of the laser focus at the plurality of locations of the focus within the modeled target volume of ocular tissue. An energy value is assigned to the plurality of locations of the focus within the modeled target volume of ocular tissue based on the final expected spot size at that location.
