摘要: The reliability of using a reference system intrinsic to the cornea has been evaluated in order characterize corneas subjects after refractive surgery. Data on 90 eyes operated by LASIK correct myopia and astigmatism were considered. corneal parameters (curvature radii asphericity) found with respect this are compared provided directly topographer. referenced main axes allow better characterization geometry, showing lower variability diminishing dissimilarities between different eyes. use these reduces discrepancies real experimental theoretically predicted values (21% mean relative error data versus 81% topographer data). To understand reduce differences is essential
