Design of multi-order diffractive intraocular lenses

The paper deals with a design method of multi-order diffractive intraocular lenses (IOL) that we have developed in order to correct chromatic aberration. It is shown that in order to prevent a color halo around the focused image the phasematching number is selected to attend at each point of the image three color components to get quality image. A computer simulation of multi-order diffractive lens (MODL) in a schematic model of the human eye was carried out. The calculated MODL focuses white light into a segment on an optical axis with high diffractive efficiency. More research needed to study an aberration analysis of lenses of this type.
