1. A method of reconstructing optical tissues of an eye, the method comprising:

  • transmitting an image through the optical tissues of the eye;

    measuring surface gradients from the transmitted image across the optical tissues of the eye;

    applying a Fourier transform algorithm to the surface gradients to reconstruct a surface that corresponds to the optical tissues of the eye; and

    correcting an off-center alignment in the reconstructed surface.
