Abstract
Journal of Refractive Surgery | ABSTRACTBACKGROUND: 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.METHODS: Curvature of a calibratedThis publication has 0 references indexed in Scilit:
