Claim:
1. A method of calculating effective powers of an optical system of a patient, through the use of a computer processor, the method comprising: calculating a first effective power using a first Zernike expansion coefficient for the optical system, the first Zernike expansion coefficient associated with a first aperture dimension; and calculating a second effective power using a second Zernike expansion coefficient for the optical system, the second Zernike expansion coefficient associated with a second aperture dimension, the second aperture dimension greater than the first aperture dimension, the second Zernike expansion coefficient scaled relative to the first Zernike expansion coefficient using a scaling factor comprising a ratio of the second aperture dimension to the first aperture dimension raised to a power of a factor comprising a radial degree of the coefficient; and determining a treatment for the optical system of the patient based on the calculated first effective power and the calculated second effective power, wherein the optical system comprises an optical tissue of the patient, the first aperture dimension comprises a first pupil dimension, and the second aperture dimension comprises a second pupil dimension, and wherein the treatment comprises a member selected from the group consisting of an intraocular lens treatment, a contact lens treatment, and a refractive laser treatment.
