DSEK

DSEK (Descemet’s Stripping Endothelial Keratoplasty)


cornea-transplantThis procedure is designed to replace the damaged or abnormal corneal endothelium (inner cell lining on the cornea) when a patient has decreased visual acuity from corneal swelling. Previously these patients would require a full penetrating corneal transplant, but new technology allows for replacement of only the abnormal endothelium.  This results in much faster visual recovery, leaving the patient with a stronger cornea and less astigmatism than what commonly occurs with a traditional transplant.

During the procedure a small incision is made and the diseased endothelium and Descemet’s membrane are removed from the inner surface of the patient’s cornea.  A disc of tissue is then taken from the inner layer of a healthy donor cornea, folded gently and inserted into the anterior chamber.  An air bubble is introduced to push the tissue into place where it eventually heals into a stable position. Typical post-operative results are in the 20/20-20/40 range and patients notice less glare and improved contrast sensitivity.

Indications:

  • Fuch’s endothelial dystrophy
  • Pseudophakic bullous keratopathy
  • Other cause of endothelial failure
  • Minimal corneal scarring
  • Best acuity 20/40 or worse
