A 91-year-old man with Fuchs dystrophy was referred to our institution for a failed Descemet stripping endothelial keratoplasty (DSEK) graft in his left eye. He had also previously undergone penetrating keratoplasty (PK) in his left eye.
After examining and consulting with the patient, we made plans to attempt a repeat DSEK. However, given the similar diameters of the preexisting DSEK and PK grafts at the time of surgery, there were concerns for internal dehiscence at the graft-host junction. As a result, a second DSEK corneal button was inserted without removal of the failed DSEK graft.
Deturgescence of the grafts and increasing clarity of the cornea were noted with follow-up six months after surgery. The three grafts (denoted by * for PK, + for the initial DSEK, and # for second DSEK) are pictured on biomicroscopy (Fig. 1) and optical coherence tomography (Fig. 2).
