Abstract

Purpose: To report the explantation of a detached and opaque donor disc as an alternative to secondary keratoplasty in a case of persistent graft detachment followed by spontaneous clearance of the recipient cornea after non-Descemet stripping automated endothelial keratoplasty (non-DSAEK). Methods: A 57-year-old man with cataract and bullous keratopathy after herpes simplex virus endotheliitis of the right eye and best spectacle-corrected visual acuity (BSCVA) of 0.1 underwent simultaneous phacoemulsification and non-DSAEK. Due to early detachment of the donor disc, two additional intracameral air injections were necessary in order to achieve graft attachment. However, the donor disc gradually detached and became fibrotic while the recipient cornea anterior to the detached graft became transparent and without any edema. Therefore, a mere explantation of the DSAEK graft was performed. Results: Four months after graft explantation, BSCVA was 0.5 and endothelial cell density (ECD) was 1,221 cells/mm2. After 13 months, BSCVA was still 0.6 while ECD had fell to 800, and 2 years later, the endothelium decompensated. BSCVA was 0.3 and ECD was not measurable. Conclusions: To our knowledge this is the first report of explantation of an endothelial graft as an alternative to re-keratoplasty in a case of spontaneous corneal clearance. This minimally invasive treatment may be considered in similar cases. However, due to the ongoing loss of endothelial cells after endothelial keratoplasty, a re-keratoplasty may still be needed in the long term.
