| Descripción: |
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 levels of corneal irregularities, from a quasi-spherical
cornea to a very deformed one. This work has been supported by the Ministerio de Educación y Ciencia (Spain) through the project no. FIS2005-05053 and by the Conselleria de Empresa, Universitat i Ciència of the Generalitat Valencia (Valencia, Spain), through the project no. ACOMP06/099. |
