If there is no vision improvement after cataract surgery and you have foreign body sensation with watering then you might be suffering from Pseudophakic Bullous Keratopathy. In this condition there is swelling in the cornea, which normally is a clear structure in the front part of the eye. The only treatment for such cases is corneal transplantation where the damaged cornea is replaced by a health donor tissue. Normally it involves 16 sutures to secure the donor cornea in place. With the new technique called DSEK only the damaged layer of the corneal is replaced by a layer of healthy donor endothelial cells.

 

It is relatively new corneal transplant procedure that replaces only the inner layers of cornea as opposed to the full thickness of the central cornea done in a traditional transplant. The visual recovery significantly faster & future related complications are essentially eliminated
  • The patient's endothelial layer is stripped from rest of the cornea
  • The donor endothelium attached to a thin layer of donor cornea is folded like a taco & inserted through 5 mm incision
  • An air bubble is injected to push the donor cornea up against the posterior surface of the patient's cornea
  • The pumping action of the new donor endothelium helps to create suction which bonds the donor tissue to the patients own cornea

Advantages of DSEK

  • Visual recovery is significantly faster
  • The eye is much stronger & gains more resistance to injury
  • Suture related complications are essentially eliminated
  • There is little or no change in the refractive error since the patient's cornea is left intact
