Corneal transplantation or Keratoplasty
Corneal transplant procedures may be carried out depending on which part of the cornea needs to be replaced, and is performed under general or local anaesthesia.
Full thickness corneal transplants or penetrating keratoplasty
Penetrating keratoplasty involves the removal of the damaged corneal and replacing it with a donated cornea. Your surgeon will use a circular cutting instrument called a trephine to cut through the thickness of the damaged cornea. The new cornea will be placed and sutured with tiny stitches around its edges.
Partial thickness corneal transplants
Partial thickness transplant involves the transplantation of only parts of the cornea. Based on the requirement, the front or back portion of the cornea will be transplanted and replaced with donor grafts.
