Abstract
A system for predicting optical power for an intraocular lens based upon measured biometric parameters in a patient's eye includes: a biometric reader capable of measuring one or more biometric parameters of the patient's eye and obtaining at least one value for at least one of the one or more biometric parameters, and further measuring a representation of a corneal topography of the patient's eye; a processor; and a computer readable medium coupled to the processor and having stored thereon a program that upon execution causes the processor to: receive the at least one value; obtain a corneal spherical aberration (SA) based upon the representation of the corneal topography; and calculate an optimized optical power to obtain a desired postoperative condition by applying the received at least one value and the obtained corneal spherical aberration to a modified regression.
