In this communication, we report a new method to determine the wavefront aberration function of personalized eyes. We obtain corneal surface data and axial lengths for different eyes. With these data, we construct a diffractive model of a human eye, which permits calculation of propagated light distributions at any distance inside the eye. We obtain the field at the exit of crystalline lens and extract the phase information. To unwrap this phase we use a path-following method and with the reconstructed phase we obtain the wavefront aberration function that we analyze using Zernike polynomials.The method allows linking between field patterns and wavefront surfaces that are softer and easier to analyze. To demonstrate the possibilities of the technique we have chosen five eyes which present different level of corneal irregularities, from quasi-spherical cornea to a very deformated one.
