1. A method for manufacturing an intraocular lens (IOL) system for improving patient's vision, the method comprising:
forming a lens from a soft hydrophobic polymeric compound, the lens having a first surface and a second surface and an optical power of P diopters;
said lens being characterized by an optical zone diameter (D) and a central thickness (T);
said first surface is spherical having a first radius of curvature (R1);
said second surface is a rotationally symmetric conic surface, having a second radius of curvature (R2), and having surface sag (z coordinate) which is a function of a radial coordinate (r) is given by:
where: c=1/r,
k=conic constant;
wherein as the dioptric power of the lens increases by more than one diopter, the conic constant remains constant.
