Postoperative month 6 status post-Descemet membrane endothelial keratoplasty tomography of the right eye shows minimal changes to the anterior curvature (a), but an inferotemporal displacement of thinning (b) associated with posterior elevation consistent with forme fruste keratoconus (c)

Scheimpflug tomography was obtained at postoperative month 6, which showed a stable anterior cornea with Ks of 43.3 D and 44.1 D, but an inferotemporal posterior elevation of + 22 um [Figure 1a-c].
Preoperative tomography of the patient's left eye with Fuchs endothelial corneal dystrophy showing minimal anterior astigmatism (a), normal anterior elevation map (b), and posterior corneal flattening consistent with mild corneal edema associated with Fuchs (c)with Fuchs (c)

Preoperatively, tomography showed Ks of 42.4 D and 43.1 D, with minimal anterior or posterior astigmatism [Figure 2a-c].
Postoperative year 1 tomography after DSAEK OS demonstrates minimal changes in the anterior curvature (a), decreased corneal thickness (b), and a symmetric posterior curvature with mild peripheral steepening but without focal elevation (c)
