ABSTRACT
PURPOSE:
Evaluating the effect of a single peripheral triangular mark to ensure the correct anterior-posterior graft orientation in DMEK.METHODS:
Retrospective study of patients scheduled for DMEK due to Fuchs endothelial dystrophy and divided into 2 study groups Group -M (n = 184) had no mark of the EDM (Endothelial Descemet membrane) and group + M (n = 193) had a triangular peripheral mark. Follow-up time was 1 year after surgery.RESULTS:
The postoperative graft turning and Re-DMEK rate could be significantly reduced by the use of a peripheral mark (p = 0.002, p = 0.001, respectively). Re-DMEK due to primary graft failure was significantly associated with prior graft turning (p < 0.001). Both groups showed comparable values for visual acuity, central corneal thickness and endothelial cell count after a follow-up of 1 year.CONCLUSION:
Single peripheral triangular marking is a simple and cost-saving addition to EDM preparation to ensure the correct orientation of the graft intraoperatively and could lead to a significant reduction in graft turning and re-DMEK rate in this study.Palavras-chave
