Claim:
1. A method for mitigating a change in pupil size of an eye of a patient while an ophthalmological procedure is performed on the eye of the patient, the method comprising: obtaining a first image of the eye with an imaging device at a first lighting condition at the eye; obtaining a second image of the eye with the imaging device at the first lighting condition at the eye; determining the change in pupil size by using the first and second images; determining, with a processor, a desired optical light output corresponding to a second lighting condition at the eye different from the first lighting condition, in response to the change in pupil size, the desired optical light output configured to induce a desired pupillary response mitigating the change in pupil size; and directing the desired optical light output from a variable illumination source to the eye while the ophthalmological procedure is performed on the eye of the patient, thereby providing the second lighting condition at the eye that mitigates the change in pupil size during performance of the ophthalmological procedure, wherein the ophthalmological procedure comprises a wavefront measurement of the eye, a laser ablation treatment of the eye, or a wavefront measurement and a laser ablation treatment of the eye.
