To describe clinical experience in DMEK with the aid of a simple positioning device.
University Affiliated Community Hospital
A retrospective chart review was conducted on eyes that had undergone DMEK surgery with a simple positioning device that aided with head position post-operatively. Pachymetry, corneal optical coherence tomography, specular microscopy, and visual acuity were assessed.
Patients reported that the positioning device helped with maintaining a face-up head positioning after DMEK surgery. One eye required re-bubbling, however, this graft was attached 360 degrees with an unusual stromal tag of tissue centrally that appeared to result in central dehiscence of the graft. One eye required a late re-graft for an attached, but non-functioning graft. At 8 months post-operatively, average pachymetry was decreased by 113um (SD 23), average endothelial cell count was 1869 cells/mm2 +/-548 (SD) and average BSCVa was 0.28 logMAR.
DMEK is a viable method for endothelial transplantation. The positioning device appears to help patients maintain a proper head position post-operatively. Further study is necessary to evaluate the long-term survival and performance of these endothelial grafts.
