A cornea transplant is an operation used to remove all or part of a damaged cornea and replace it with healthy cornea tissue from the eye of a suitable donor.
Like other graft operations that use living tissue, there is a potential for corneal graft rejection which can lead to failure of the graft. The do nor cornea used in DSAEK is preserved in an eye bank, and the corneal endothelial density is evaluated by microscopy.he surface of the cornea is an extremely important component of the optical system of the eye, so any irregularity in the corneal shape has a major effect on visual performance. Because DSAEK only exchanges the inner cell layers of the cornea it has little or no effect on its external shape.
