FIGURE 3. — Cross sections comparing automated and traditional endothelial keratoplasty. Transplanted tissue is colored, and the recipient eye is grayed out. A, Traditional DSEK grafts include manually resected layers of stroma, Descemet’s membrane, and endothelium. B, DSAEK grafts are produced by microkeratome or femtolaser incisions and may reduce the stromal thickness compared with DSEK. C, Traditional DMEK grafts include manually resected Descemet’s membrane and endothelium with no stromal tissue. D, DMAEK grafts are produced by microkeratome or femtolaser incisions and may include a peripheral rim of stromal tissue not included in DMEK. DMEK, Descemet membrane endothelial keratoplasty; DMAEK, Descemet membrane automated endothelial keratoplasty; DMEK, Descemet membrane endothelial keratoplasty; DSAEK, Descemet stripping automated endothelial keratoplasty; DSEK, Descemet stripping endothelial keratoplasty.
