DSEK removes the diseased innermost corneal membrane that is then replaced by a healthy donor transplant.  DSEK is state of the art and offers several benefits over other methods of corneal transplants. Because the procedure is less invasive, DSEK leaves the eye stronger and less prone to injury than full-thickness transplants. Additionally, DSEK has a more rapid rate of visual recovery. Vision is typically restored in a matter of weeks rather than over many months.
