Clinical Study
Changes in Anterior, Posterior, and Total Corneal Astigmatism after Descemet Membrane Endothelial Keratoplasty
Figure 3
Showing correlations between the magnitudes of anterior posterior and total corneal astigmatism before (blue) and after (red) DMEK surgery. Before surgery, we found a significant correlation between the magnitudes of anterior and posterior corneal astigmatism (Spearman’s correlation coefficient , ); after surgery, this correlation was not significant (, ).
