Characterization of the Inherit Error in a Spherically-Biased Corneal Topography System in Mapping a Radially Aspheric Surface (Articolo in inglese)

Accurate measurement of corneal topography is crucial for many clinical applications. Also, the human cornea is known to be an asphere. Therefore, the purpose of this study was to quantitatively evaluate the accuracy of the EyeSys Corneal Analysis System in measuring a radially aspheric test surface and characterize the error function.
