Look-up table of quadrics applied to corneal topography

We present a new look-up table method to convert acquired corneal data from reflected Placido rings to curvature radii. The technique avoids extrapolating corneal data and overcomes the difficulty with the lack of symmetry of projected rings and provides a better description of the corneal morphology.
