Comparison of Numerical Eye Models and its Representation within a Mechanical Eye Model*

Today the increased computer power admits very detailed numerical modelling of the human eye. Simultaneous new technologies as well as the defined production of aspherical lenses permits the realization of nearly realistic ex vivo mechanical simulation of the natural human eye. Amongst others such ex vivo mechanical eye models are used to verify the optical quality of new intraocular lenses. Measurements of modulation transfer function (MTF) performed by an ex vivo mechanical eye model and numerical analysis of saggital and tangential MTF are presented.
