Refractive surgery: a guide to assessment and management. Corneal topography and its role in refractive surgery. This chapter exposes the basics of the corneal topography and wavefront sensing theory and explains how these techniques can be used to predict and improve the optical performance of the human eye. Wavefront aberrometers are powerful diagnostic tools to address visual complaints of optical origin by measuring and correcting not only the spherical and cylindrical components of refraction but also the aberrations of the visual system that may affect the visual performance. It has become an indispensable tool in anterior segment surgery for the diagnosis of corneal diseases and designing methods of vision correction. Corneal topography consists in measuring the shape, refractive power, and the thickness of the cornea.
