Key Takeaways
- A corneal transplant replaces a damaged cornea, or part of it, with healthy tissue from a deceased donor.
- Doctors may recommend one for conditions such as Fuchs' dystrophy, advanced keratoconus, corneal ulcers, or damage from earlier eye surgery.
- Surgery typically takes less than two hours, and recovery depends on the type of transplant.
- Over 97% of corneal transplant operations successfully restore the recipient's vision, according to the Eye Bank Association of America (EBAA).
- Everett & Hurite Eyecare Specialists offers corneal care in the Pittsburgh area, and patients with cornea concerns can request an appointment to learn whether a transplant could help.
What Is a Corneal Transplant?
The cornea is the clear, dome-shaped front layer of the eye. It focuses light so you can see clearly. A corneal transplant is surgery that removes a damaged cornea and replaces it with healthy donated tissue. According to Cleveland Clinic, all corneal transplants use corneas from deceased human donors, and every donor cornea goes through thorough testing before it is used.
Which Conditions May Lead to a Corneal Transplant?
A cornea transplant is usually considered after other treatments are no longer enough. Cleveland Clinic lists these common reasons:
- Fuchs' dystrophy, a condition that affects the inner layer of the cornea.
- Keratoconus, where the cornea thins and bulges into a cone shape.
- Corneal ulcers or other damage from injuries, inflammation, and infections.
- Corneal damage caused by earlier eye surgery.
- Bullous keratopathy, a blister-like swelling of the cornea.
How Keratoconus Relates to Needing a Transplant
Many people with keratoconus never need a transplant. Glasses, specialty contact lenses, and corneal cross-linking can manage the condition in many cases. Cleveland Clinic notes that a transplant may be suggested when keratoconus is advanced. Everett & Hurite offers keratoconus cross-linking, a treatment designed to stabilize the cornea and stop keratoconus from progressing, which may help some patients avoid surgery.
How Is Donor Corneal Tissue Matched to a Recipient?
Corneal tissue is different from many other transplants. The EBAA explains that everyone is a universal donor for corneal tissue, which means the donor's blood type does not have to match the recipient's. Eye banks evaluate each donated cornea under strict EBAA medical standards and U.S. Food and Drug Administration (FDA) rules before it is released for surgery.
Timing matters too. The EBAA reports that the preservation medium used in the United States keeps a cornea's cells alive for 14 days after recovery, though most transplants happen within a week. The gift is also anonymous, so recipients are not told who the donor was. If they wish, they can write an anonymous thank-you letter through the eye bank. These details are explained on the EBAA frequently asked questions page.
What Are the Types of Corneal Transplant Surgery?
The cornea has three layers. The type of transplant depends on which layers are damaged. Dr. Hall McGee IV, a cornea and cataract specialist at Everett & Hurite, has clinical experience with full-thickness transplants and partial-thickness techniques, including endothelial and anterior lamellar transplants.
| Type of Transplant | What Is Replaced | Typical Vision Recovery |
|---|---|---|
| Penetrating keratoplasty (full-thickness) | The entire center of the damaged cornea | May take up to 12 months for full vision |
| Deep anterior lamellar keratoplasty (partial-thickness) | The middle and outer layers, when the inner layer is healthy | Varies, so ask your surgeon what to expect |
| Endothelial keratoplasty (partial-thickness) | The innermost layer, called the endothelium | Good vision is often possible within three months |
Recovery times come from Cleveland Clinic. Because outcomes vary, your surgeon can explain what to expect for your own eye.
What Happens Before, During, and After a Corneal Transplant?
Before Surgery
Your surgeon and the anesthesia team review your medical history, answer questions, and confirm the surgical plan. They will tell you if you need to stop any medicines and when to stop eating and drinking. Plan on having someone drive you home, since you will not be able to drive yourself.
During Surgery
The anesthesia team uses either sedation or general anesthesia, depending on your health and the plan you and your surgeon discussed. Numbing medicine is also applied to the eye. The surgery typically takes less than two hours.
The First Days After Surgery
Your eye may be red, irritated, and sensitive to light for the first few days. Most patients wear an eye patch and return for a follow-up visit within 24 to 48 hours. Patients who have an endothelial transplant also need to lie face up for a few days. That position lets an air bubble hold the new tissue in place.
What Does Corneal Transplant Recovery Look Like?
Recovery is gradual, and blurry vision at first is normal. Cleveland Clinic shares these key points for the weeks and months that follow:
- Prescription eye drops help prevent infection, reduce swelling, and lower the risk of rejection. Patients use eye drops for at least a year.
- Some stitches may stay in for several months, depending on the type of surgery.
- Do not rub or press on the eye while it heals.
- Glasses or protective eyewear help shield the eye during recovery.
- Some patients need glasses or specialty contact lenses afterward to sharpen vision.
For patients who need specialty lenses after surgery, Dr. Natalie Noble focuses on corneal disease and specialty contact lenses, including care for irregular and post-surgical corneas.
What Are the Warning Signs of Corneal Transplant Rejection?
Rejection happens when the immune system treats the donated cornea as foreign. Contact your surgeon right away if you notice:
- Eye pain.
- Eye redness.
- Hazy or cloudy vision.
- Sensitivity to light.

Frequently Asked Questions
What is the corneal transplant success rate?
The EBAA reports that over 97% of corneal transplant operations successfully restore the recipient's vision. Long-term results depend on the cause of the cornea damage, the surgical technique, and how the immune system accepts the donor tissue.
How long is corneal transplant recovery?
It depends on the type of surgery. Cleveland Clinic notes that a full-thickness transplant may take up to 12 months for full vision, while an endothelial transplant may reach good vision within about three months.
Can keratoconus be treated without a corneal transplant?
Often, yes. Glasses, specialty contact lenses, and corneal cross-linking can help many patients. A transplant is usually saved for advanced cases.
Is corneal transplant surgery painful?
The eye is numbed during surgery. Afterward, the eye may feel red, irritated, and sensitive to light for a few days, and over-the-counter pain relief recommended by your surgeon can help.
