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.

Am I A Candidate For A Cornea Transplant?

To determine if you are a good candidate for a cornea transplant in San Antonio, TX at Focal Point Vision, our experienced team of doctors will begin by performing a thorough eye examination and a review of your medical history. Typically, the best candidates for a cornea transplant are in good overall health and have one of a number of eye conditions that often include:

  • Corneal ulcers
  • Keratoconus
  • Fuch's dystrophy
  • Thinning corneas
  • Corneal scarring
  • Corneal clouding
  • Damage to the cornea from illness or injury


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.

DALK and PKP Corneal Transplant FAQ

Does a corneal transplant hurt?

No, it doesn't. Depending on the necessities of your corneal transplant, it may be performed with local anesthesia or under general anesthesia (you’re asleep). But you will not feel pain during either type of anesthesia. During your consultation, we will talk to you about your options and the best route to achieve optimal results.

Are corneal transplants safe?

Yes, they are. Corneal transplants are considered relatively safe for the majority of candidates. All surgeries, no matter how minor, carry a small amount of risk, and a corneal transplant only has a very small risk of complication, typically eye infection.

How long is recovery after a corneal transplant?

If you have a PKP procedure, you may need to stay in the hospital overnight. A DALK procedure is performed as an outpatient procedure, meaning you can go home. Most patients will be able to get back to routine activities in about 2 – 3 weeks. Full recovery with your vision returning can take anywhere from 3 – 4 weeks to a year.
