Abstract

A numerical method to calculate surfaces for refractive multi-focal intraocular lenses is presented. The computations, performed in a plane containing the axis of rotation of the surface, provide sag values as well as the curvature of the surface between values. Standard ray tracing techniques may then be applied to the calculated surface to verify the optical performance.
