<p>Topography-Guided Refractive Astigmatism Outcomes: Predictions Comparing Three Different Programming Methods</p>

Abstract

Our study suggests that using the topographically measured cylinder or the cylinder selected by Phorcides will produce more desirable refractive outcomes than entry of the preoperative refractive cylinder as the basis for correction of myopia and myopic astigmatism with the WaveLight Contoura Vision excimer laser.
