In sight correction technologies, it is of extreme importance to know what outcome of the planned operation could be. Conventionally, cornea shape is measured, or even refraction distribution in the eye, that are used for calculations of the to-be-ab

A modified double-pass wave model is proposed being a wave diffraction model of the secondary coherent field formed due to double pass of light in the human eye system. The modification takes into account: cornea contribution into total eye refractio
