Recipient Endothelium May Relate to Corneal Clearance in Descemet Membrane Endothelial Transfer

DMET may be effective in the management of Fuchs endothelial dystrophy (primarily a Descemet membrane disorder), but not in bullous keratopathy (primarily an endothelial depletion). Apparently, the indication for surgery (ie, a “dystrophy” vs a “depletion” of recipient endothelial cells) relates to the capacity of the cornea to clear. This suggests that the remaining rim of recipient endothelium (after descemetorhexis) is involved in the re-endothelialization of the recipient posterior stroma after DMET.
