Scanning spot locations are generated for ablating tissue using a scanning laser beam over a treatment region by taking a target function representing a desired lens profile of ablation with a basis function representing a treatment profile produced by overlapping scanning spots in a particular treatment pattern. In some embodiments, the basis function is a two-dimensional function representing a two-dimensional section of a three-dimensional treatment profile, which has symmetry with respect to the two-dimensional section extending along the treatment pattern. For example, the treatment pattern is generally straight for myopic and hyperopic cylinders, and is generally circular for myopia and hyperopia.
