Claim 0:
1. A method for vergence matching for an intraocular lens (IOL), the method comprising:
determining a desired phase map for producing, by refractive index writing, a phase change in an IOL, the IOL having an anterior surface and a posterior surface;
calculating vergence of a wave after refraction on the anterior surface of the IOL for a desired wavelength design;
propagating a corresponding wavefront to the plane of the refractive index writing within the IOL;
estimating curvature of the wavefront in the plane of the refractive index writing; and
based on the estimated curvature, converting an initial phase map into a vergence-matched three-dimensional (3D) phase map, such that the initial phase map follows the curved vergence of the wavefront.
