Early Experience With DMEK Using Novel Folding Insertion Technique
Narrative Responses:
Purpose
To present our early experience with Descemet’s Membrane Endothelial Keratoplasty (DMEK) with special attention to a novel folding donor tissue insertion technique.
Methods
A retrospective review of the records of all patients having undergone DMEK by a single surgeon was undertaken. These records were reviewed for a number of variables including: tissue insertion technique, surgical complications, need for rebubbling, tissue detachment, primary graft failure, length of follow-up, visual acuity, and operative times. Additional variables to be evaluated will include: endothelial cell counts, visual outcome, and graft survival.
Results
To date 24 patients are included (14 with a novel folding technique and 10 with an injector technique). Rebubbling rates for the two groups were 42% folding group and 20% injector group. 1 patient in each group had a complete DMEK button detachment. Follow up is currently short (12 mos. for the folding group 3 mos. for the injector group) indicating our early experience. Vision is good with 57% of the folding group and 50% of the injector group seeing ≥ 20/30 at last follow up. Additional patients will be included in the review.
Conclusion
DMEK is a viable technique of endothelial transplantation. A novel folding donor tissue insertion technique may simplify the procedure and shorten operative times while maintaining good post operative outcomes. Additional conclusions will be included as data become available.
