Wavefront technology: a new advance that fails to answer old questions on corneal vs. refractive astigmatism correction.

standing of the eye’s refractive characteristics to a new level. It has changed our concepts for examining refraction in the same way that computerized corneal topography changed corneal surface measurement, which previously had been limited to the yardstick of keratometry. We now possess two, highly sensitive tools for the objective measurement of the eye—corneal topography and wavefront assessment. Our challenge is to reconcile them toward the ultimate goal: the best possible vision for our patients.
