Abstract

A method for performing a corneal ablation procedure on an eye of a patient including determining a refractive correction for the eye and determining a first parameter corresponding to the refractive correction or a condition of the patient. An ablation profile is selected that includes a refractive correction component and a pre-compensating component that is selected based on the first parameter. The ablation profile is configured to promote a controlled induction of a higher order aberration, where the pre-compensating component limits the induction of the higher order aberration to be within a predefined range. The cornea is ablated using the selected ablation profile.
