Successful YAG Laser Treatment for Epithelial Ingrowth in Descemet Stripping Endothelial Keratoplasty Interface

Purpose: To present a case of epithelial ingrowth in the graft–host interface after Descemet stripping endothelial keratoplasty (DSEK) surgery that was successfully treated with an Nd:YAG Laser. Methods: A 79-year-old Caucasian female underwent a repeat DSEK 9 months after a prior DSEK graft rejection and subsequent failure. At her regularly scheduled 1-month follow-up visit, an asymptomatic dense white interface opacity was observed within the stromal interface, with an appearance consistent with epithelial ingrowth. The depth and location was confirmed by anterior segment optical coherence tomography. After initial observation, the opacity was noted to be growing over 2 months. The epithelial ingrowth cells were then treated with an Nd:YAG Laser. Results: The patient remained stable 12 months post laser treatment with no recurrence of epithelial ingrowth. Focal stromal pits were noted at the site of Nd:YAG Laser treatment within the DSEK graft stromal interface, but were not visually significant. Conclusions: Nd:YAG laser treatment is a safe and effective way to treat early-stage epithelial ingrowth in the interface after DSEK surgery.
