Changes in Anterior, Posterior, and Total Corneal Astigmatism after Descemet Membrane Endothelial Keratoplasty

Figure 4

Showing the differences in magnitude and orientation between anterior and total corneal astigmatism before (blue) and after (red) DMEK. The figure illustrates the complexity of the estimation of total corneal astigmatism based on anterior corneal curvature. Note the large number of outliers.
