Postkeratoplasty Anterior and Posterior Corneal Surface Wavefront Analysis: Descemet’s Stripping Automated Endothelial Keratoplasty versus Penetrating Keratoplasty
Figure 1
Box-plot representation of the magnitude (expressed as RMS in μm) of the total, 3rd and 4th order HOAs due to the anterior corneal surface within the 4 mm (a) and 6 mm (b) central zones, and due to the posterior corneal surface within the 4 mm (c) and 6 mm (d) central zones, in the control, PK and DSAEK groups. The magnitude of the spherical aberration was expressed as absolute value. Median values are represented as dark lines, 25/75 percentiles as boxes, 5/95 percentiles as bars, and outliers as circles.
