Claim One:
1. A system for predicting optical power for an intraocular lens to obtain a desired postoperative condition, comprising: a first device configured to measure at least one biometric parameter of a native eye; a second device configured to obtain a corneal spherical aberration of the native eye; at least one computing processor configured to apply a modified regression formula to the at least one biometric parameter and the corneal spherical aberration to determine an optical power; and an output device configured to output the optical power, wherein the modified regression formula is of the form: 
 optical power=Regression+constant0*(corneal spherical aberration) 
 or 
 optical power=constant1*(biometric parameter)+constant0*(corneal spherical aberration) wherein constant1 and constant0 comprise an empirically derived factor across other eyes, and wherein the Regression comprises a predicted optical power derived from a classical regression formula.
