A corneal transplant is a surgical procedure that replaces a damaged or diseased cornea with healthy donor tissue to restore vision, reduce pain, and improve eye function.
Why is the Cornea Important?
-
Clear outer layer of the eye
-
Focuses light for sharp vision
-
Protects the eye from debris and infection
Who Needs a Corneal Transplant?
Common Conditions Treated
✔ Keratoconus (thinning, cone-shaped cornea)
✔ Corneal Scarring (from infections, injuries, or burns)
✔ Fuchs’ Dystrophy (endothelial cell loss)
✔ Bullous Keratopathy (swelling due to endothelial failure)
✔ Corneal Ulcers (severe infections)
Types of Corneal Transplants
| Type | Description | Best For |
|---|---|---|
| Penetrating Keratoplasty (PKP) | Full-thickness cornea replacement | Severe scarring, advanced keratoconus |
| Deep Anterior Lamellar Keratoplasty (DALK) | Replaces outer & middle layers | Keratoconus, superficial scars |
| Endothelial Keratoplasty (DSEK/DMEK) | Replaces only inner endothelial layer | Fuchs’ dystrophy, endothelial failure |
What to Expect: Before, During & After Surgery
Before Surgery
-
Comprehensive eye exam (to assess corneal damage)
-
Donor cornea matching (tested for safety & compatibility)
During Surgery
-
Local or general anesthesia (no pain during procedure)
-
Damaged cornea removed, donor tissue stitched or secured
-
Duration: 30–90 minutes (depending on type)
After Surgery
-
Protective shield worn for a few days
-
Eye drops (antibiotics & anti-inflammatory) for months
-
Stitches removal (if used) in 6–12 months
-
Full recovery: 6–12 months (vision improves gradually)
Success Rates & Risks
Success:
-
90%+ success rate for most conditions
-
Faster recovery with newer techniques (DMEK/DSEK)
Possible Risks:
-
Rejection (5–30% risk; treatable if caught early)
-
Infection (rare with proper care)
-
Astigmatism (may require glasses/contacts post-surgery)
Signs of Rejection:
-
Redness, pain, light sensitivity, vision loss → See your doctor immediately!
Advances in Corneal Transplants
🔹 Femtosecond laser-assisted surgery (more precise cuts)
🔹 Artificial corneas (for high-risk patients)
🔹 Better donor tissue preservation (extends usability)
Life After a Corneal Transplant
-
Most patients regain functional vision
-
Regular follow-ups needed to monitor healing
-
Contact lenses/glasses may still be required
FAQs
Q: How long does a donor cornea last?
A: Transplanted corneas can last decades with proper care.
Q: Can I drive after surgery?
A: Not immediately—vision may be blurry for weeks.
Q: Are there alternatives to transplants?
A: For early keratoconus, corneal cross-linking may help.
Is a Corneal Transplant Right for You?
If you have:
🔸 Severe corneal scarring
🔸 Painful corneal swelling
🔸 Vision loss unimproved by glasses
Consult an ophthalmologist to explore options!
