Claim 0:
1. A method for determining cross sections of a first diffractive profile for an intra-ocular lens (IOL), said IOL comprising at least one diffractive surface including a plurality of discrete, adjacent, diffractive, concentric Fresnel zones, said method comprising, selecting diffractive orders of said IOL;
selecting a normalized first energy flux distribution of said diffractive orders;
employing the Gerchberg-Saxton algorithm to generate cross sections of a first zone comprising a repetitive pattern of a first diffractive profile of said Fresnel zones, said first diffractive profile associated with said first flux distribution of said diffractive orders; and
producing said IOL in accordance with said generated cross sections.
