1. A method of inhibiting an induced aberration resulting from refractive surgery, the method comprising: (a) inputting a target optical surface shape; (b) determining a model optical surface shape based on the target optical surface shape and a set of refractive surgery system parameters; (c) comparing the target optical surface shape and the model optical surface shape to determine an aberration induced by the set of refractive surgery system parameters; and (d) adjusting the set of refractive surgery system parameters so as to inhibit the induced aberration.
