Abstract
PURPOSE: To describe a bimanual vitrectomy technique for the removal of a descemet-stripping automated endothelial keratoplasty donor graft dislocated into the vitreous cavity. METHODS: The surgical technique requires the use of a temporary keratoprosthesis and external chandelier illumination to overcome corneal edema and visualization of the dislocated donor graft, respectively. A bimanual pars plana vitrectomy approach is then performed with intraocular forceps and the vitrectomy handpiece for segmentation and removal of the dislocated graft. Penetrating keratoplasty is then performed to restore corneal clarity. RESULTS: This surgical technique allows for the dislocated descemet-stripping automated endothelial keratoplasty donor graft to be removed from the vitreous cavity safely in an efficient manner. CONCLUSION: The technique of bimanual pars plana vitrectomy with a temporary keratoprosthesis and external chandelier illumination can successfully remove a descemet-stripping automated endothelial keratoplasty donor graft dislocated into the vitreous cavity without the need for a large wound for donor graft explantation.
