The shape of the cornea plays an important role in focusing light on the retina. A standard shaped cornea and a healthy, clear lens allows light to focus clearly. If the cornea becomes cloudy or if the cornea becomes irregular in shape, vision can be impaired. Modern technology has made corneal transplantation a successful procedure, allowing patients to receive clear vision through a partially or fully replaced cornea transplant surgery.
If the whole thickness of the cornea is unhealthy, a full thickness corneal transplant called a Penetrating Keratoplasty (PK) will be required. During the PK procedure a circle of corneal tissue is removed and replaced with the donor tissue. This new corneal tissue will be stitched into place for a comfortable and smooth healing process.

DSEK is a partial thickness corneal transplant that requires a thin piece of donor tissue to be placed on the back surface of the cornea. The DSEK procedure is designed for patients who have clouded corneas as a result of endothelial dysfunction. The endothelium pumps fluid from the cornea to keep the tissue clear. If these cells are not working properly, the cornea will become cloudy and will swell. Instead of transplanting the full cornea, only the diseased pump cells will be replaced.
Unlike the full thickness Penetrating Keratoplasty (PK), DSEK uses a much smaller incision resulting in a more stable wound that is less likely to open with trauma. DSEK can also reduce the risk of complications such as hemorrhaging that could threaten your vision.
