Representative cases of slit-lamp microscopy and AS-OCT after endothelial keratoplasty.
(A) Slit-lamp photograph 6 months after DMEK. (B) Slit-lamp photograph 6 months after DSAEK. (C) AS-OCT section 6 months after DMEK. (D) AS-OCT section 6 months after DSAEK. (E) Posterior map using AS-OCT 6 months after DMEK. (F) Posterior map using AS-OCT 6 months after DSAEK. Postoperatively, a DMEK eye is difficult to distinguish from a normal eye after cataract surgery (A). However, we can see the scarring edge of the DSAEK graft (B). An AS-OCT section shows the natural posterior curvature in the DMEK eye (C), whereas the DSAEK eye has a meniscus-shaped posterior protrusion in the central cornea (D). The posterior color is cool in the DMEK eye (E), but red in the central cornea of the DSAEK eye (F). The arrows show the virtual peripheral edges of the DMEK and DSAEK grafts. Abbreviations: AS-OCT, anterior segment optical coherence tomography; DMEK, Descemet’s endothelial membrane keratoplasty; DSAEK, Descemet’s stripping automated endothelial keratoplasty.
