WHAT IS A Corneal Transplant?

A cornea transplant is one of the most widely known and performed types of transplants. At Focal Point Vision in San Antonio, TX, we perform this surgery when patients have severely damaged or scarred corneal tissue that can only be solved with removal and a donor transplant. We offer many different types of corneal transplants, including lamellar and penetrating keratoplasties. While a penetrating keratoplasty (PKP) is a full-thickness transplant (meaning that the entire cornea is removed), a deep anterior lamellar keratoplasty (DALK) only takes away the portion of the cornea that is scarred and damaged.


At Focal Point vision, we offer two different types of keratoplasties depending on your unique situation:

  • Deep anterior lamellar keratoplasty (DALK) is an option when the inner layers of the cornea are healthy, but the outer portions are not. Some conditions that could call for this type of procedure include keratoconus and corneal scars. For DALK, the inner corneal layer (the endothelium) is left intact and all other layers of the cornea are removed.
  • Reserved for more severe cases, full-thickness corneal transplants (also known as penetrating keratoplasty/PKP) involve the removal of a larger section of tissue from the diseased or injured cornea.
