You may need a corneal transplant if:

  • Medications can’t treat your corneal ulcer.
  • The medications healed the corneal ulcer but left a scar that interferes with your vision and is too deep for laser treatment (PTK).

In either case, you’ll need a new cornea to restore your vision. The tissue for a corneal transplant comes from a person who has recently died. The tissue is tested to make sure it’s healthy before the old corneal tissue is removed and the new tissue is stitched in place in your eye.
