"The Spinning Technique" for Unfolding Tightly Scrolled DMEK Grafts.

Purpose: We present a no-touch Descemet membrane endothelial keratoplasty (DMEK) technique which assists in unfolding of tightly scrolled grafts from young donors.

Methods: The technique was developed following a wet-laboratory experiment using human corneas created to observe the behavior of the graft during spinning within the artificial anterior chamber. This approach involves injecting short bursts of balanced salt solution to make the scroll spin continuously in a 360-degree manner.
