This study reports a newly identified complication of gonioscopy-assisted transluminal trabeculotomy (GATT) surgery observed in a patient with a history of Descemet membrane endothelial keratoplasty (DMEK). A 38-year-old male patient with uncontrolled intraocular pressure (IOP) following repeat DMEK underwent GATT surgery. During the procedure, a partial graft detachment occurred during viscoelastic removal via irrigation/aspiration. The graft was successfully repositioned by injecting air into the anterior chamber. Postoperatively, the graft remained adherent, and although an IOP spike occurred on day 19, the pressure was successfully stabilized with medical therapy. This case highlights that while GATT is effective in eyes with a history of DMEK, there is a risk of graft detachment that requires intraoperative monitoring and can be managed with air tamponade.
