An intraocular lens, and a system and method of providing an intraocular lens, having at least one characteristic of the intraocular lens customized in accordance with a modified regression that includes a modification for corneal spherical aberration. The lens, system and method may indicate measuring at least one biometric parameter of an eye at a desired light level, determining a desired postoperative condition of the eye, obtaining a corneal spherical aberration of the eye, applying at least one empirically derived regression calculation, and predictively estimating, in accordance with an output of the at least one empirically derived regression calculation, the at least one characteristic of the intraocular lens to obtain the desired postoperative condition. The empirically derived regression calculation includes at least a product of the corneal spherical aberration with an empirically derived corneal spherical aberration constant, and a mathematical indication of the at least one biometric parameter or one of the paraxial regression formulas commonly used in clinical practice to calculate IOL power in normal patients. |
