A rapid method for descemet membrane endothelial keratoplasty (DMEK) graft creation

Abstract Details

Purpose:

To describe the steps of a new, quick technique for harvesting DMEK grafts

Setting:

Parker Cornea / tertiary referral center

Methods:

Ten corneo-scleral buttons were mounted endothelial side up and stained for visualization. A hockey-stick blade was used to detach a small area of peripheral descemet membrane (DM) inward, toward the corneal center. Because the fibers that anchor DM to the stroma run circumferentially in the periphery, the freed DM edge could be grasped and peeled completely around. After detaching the edges, the DM center was stripped from the posterior stroma by gentle traction. The DM and attached ring of trabecular meshwork was then transferred to a soft contact lens and trephined, whereupon a DM roll spontaneously formed.

Results:

All graft preparations were uneventful and without complication. Each produced one intact DM graft, along with undamaged anterior corneal tissue, potentially useful for a separate lamellar surgery.

Conclusions:

By peeling DM in the direction of its stromal attachments – circumferentially in the periphery, and radially towards the center – graft creation may proceed quicker, with less tissue strain, and potentially with greater success.
