title: Iatrogenic extreme corneal decompensation treated by sequential Descemet's Stripping Endothelial Keratoplasty surgeries six months apart.
abstract: Descemet's stripping endothelial keratoplasty (DSEK) is now the most common surgical procedure to treat endothelial dysfunction although it is known that endothelial cell survival is an issue of concern. We present a case whereby severe iatrogenic corneal decompensation caused by Descemet's membrane detachment following premature disconnection of an infusion tube at the end of a trans pars plana vitrectomy and epiretinal membrane peel was successfully treated with two staged DSEK procedures six months apart. The patient was counselled that due to the severity of his extreme corneal oedema more than one DSEK procedure may be needed and the procedure was planned from the outset as a two-stage procedure. There was a measurable decrease in corneal thickness and increase in visual acuity following both the first and second procedures, which may be due to reinvigoration of the endothelial cell count following each procedure. We suggest that repeating the DSEK procedure, even when the first operation has gone well and the graft appears healthy, may be beneficial in obtaining further improvement in cases of severe corneal oedema.
