The Descemets Membrane (containing the diseased Endothelium) is removed from the patient undergoing DSEK.

Next, the trephined donor tissue, comprised of Endothelium, Descemets membrane and a small amount of Stromal Tissue, is folded in half.

The donor tissue is then inserted into the eye through a small incision.

Using an air bubble, the donor tissue is unfolded and appropriately positioned.  The air bubble is either allowed to resorb spontaneously, or removed at the slit-lamp. Visual acuity improves dramatically after several weeks of healing.
