Abstract
The cornea may be considered as the major contributor to the ocular aberrations. For normal corneas working with parallel beams, the best image plane correspond to the image distribution in the focal plane. Working with highly deformed corneas, the focal plane is not well defined and thus further analysis has to be done. Different light distribution propagated from the cornea will be analyzed here. In order to evaluate these patterns we propose three different simple parameters that will provide useful information at low computational cost. The method can be applied in optometry clinics. Since it would be convenient to optimize the image formation process by a correcting lens before performing any surgical process over the cornea.
