Measures of posterior corneal (PC) asymmetry. A, Illustrations of the central 4- and 6-mm zones of 134-μm-thick (top) and 49-μm-thick (bottom) grafts. B, Illustrations of PC surface deviation from a best-fitted sphere (top) and a corresponding color-coded elevation subtraction map (bottom) showing positive and negative differences in green and blue, respectively. C, Anterior segment optical coherence tomography images showing 134-μm-thick (left) and 49-μm-thick (right) grafts 6 months postoperatively. D, Color- coded elevation subtraction maps. E, Topography-derived higher-order aberration maps of PC surfaces shown in the corresponding left and right images of C, respectively (derived using a commercially available imaging system [Pentacam; Oculus, Inc]).

Relationship between visual gain and central graft thickness, excluding eyes with visual-limiting comorbidities. After excluding eyes with vision-limiting comorbidities, visual gain correlated with central graft thickness 6 months after Descemet stripping automated endothelial keratoplasty. The solid line represents the linear regression fit across all subjects (Pearson correlation coefficient, r = −0.35 [P =.02]). Figure Legend:

Relationship between visual gain and central graft thickness among patients with preoperative pseudophakic bullous keratopathy. Among these patients, visual gain correlated with central graft thickness 6 months after Descemet stripping automated endothelial keratoplasty. The solid line represents the linear regression fit across all subjects (Pearson correlation coefficient, r = −0.62 [P =.01]). Figure Legend:

Relationship between posterior corneal (PC) asymmetry and central graft thickness. Posterior corneal asymmetry correlated with graft thickness in the 4-mm (Spearman correlation coefficient, r = 0.32 [P =.007]) and 6-mm (r = 0.32 [P =.006]) central zones 6 months after Descemet stripping automated endothelial keratoplasty. LogRMSE indicates logarithm of the root mean square error. Figure Legend:

Relationship between total posterior corneal higher-order aberrations (PC HOAs) and PC asymmetry. Total PC HOAs (third to eighth Zernike order) correlated with PC asymmetry in the 4- (Spearman correlation coefficient, r = 0.66 [P <.001]) and 6- mm (r = 0.47 [P <.001]) zones 6 months after Descemet stripping automated endothelial keratoplasty. LogRMSE indicates logarithm of the root mean square (RMS) error. Figure Legend:
