Cornea Transplant
New Cornea, Clearer Vision
Vision depends on the eye’s ability to focus light clearly onto the retina. When the cornea, the transparent front layer of the eye, becomes damaged or diseased, vision can blur, distort, or be lost entirely. In such cases, medications and corrective lenses may no longer be effective.
An eye transplant, medically known as a corneal transplant, replaces the damaged cornea with healthy donor tissue to improve visual clarity and comfort. India has developed strong capabilities in corneal transplantation, supported by trained ophthalmologists, modern eye banks, and refined microsurgical techniques. This guide explains when the procedure is recommended and what patients can expect throughout the process.
What Is a Corneal Transplant
A Corneal transplant is when the cornea of the eye is replaced. The procedure restores the eye’s ability to transmit and focus light properly by introducing clear, healthy donor corneal tissue.
A Corneal transplant specialist evaluates corneal health, vision loss severity, and overall eye condition before recommending surgery.
Understanding the Eye and Cornea
The cornea is the eye’s outermost layer and plays a major role in focusing incoming light. It must remain clear and properly shaped for sharp vision.
Scarring, swelling, thinning, or clouding of the cornea disrupts light entry, leading to visual impairment. Corneal transplantation corrects this optical barrier, allowing light to pass through normally once healing occurs.
Conditions That May Require an Eye Transplant
An eye transplant may be recommended for conditions such as:
- Keratoconus
- Corneal scarring from infection or injury
- Corneal dystrophies
- Failed previous corneal surgery
- Severe corneal infections
- Chemical or thermal eye burns
Your ophthalmologist determines whether corneal replacement is the most effective option.
When Doctors Recommend an Eye Transplant
Corneal transplantation is considered when:
- Vision loss interferes with daily activities
- Corneal damage is permanent
- Non-surgical treatments no longer help
- Pain or recurrent infections persist
The decision is based on visual potential, eye health, and expected surgical benefit.
Types of Corneal Transplant
Penetrating Keratoplasty (Full-Thickness Transplant)
The entire thickness of the cornea is replaced with donor tissue.
Deep Anterior Lamellar Keratoplasty (DALK)
Only the front layers of the cornea are replaced, preserving the patient’s inner corneal layer.
Endothelial Keratoplasty (DSEK / DMEK)
Only the innermost corneal layer is transplanted, commonly used for endothelial disorders.
Your eye transplant surgeon selects the technique based on the affected corneal layer.
How a Corneal Transplant Is Done?
-
1
Pre-Surgical Eye Assessment
Detailed eye imaging and measurements are performed.
-
2
Donor Tissue Preparation
Corneal tissue is sourced from an eye bank and prepared.
-
3
Microsurgical Transplant
The damaged corneal tissue is replaced with donor tissue.
-
4
Stabilisation
Fine sutures or tissue positioning techniques secure the graft.
-
5
Post-Surgery Observation
Vision and graft clarity are monitored closely.
-
6
Long-Term Follow-Up
Gradual visual improvement occurs over weeks to months.
Risks and Possible Complications
Possible risks include:
Graft rejection
Infection
Increased eye pressure
Astigmatism
Delayed visual recovery
These are managed through regular follow-up and medication.
Eye Transplant Success Rate
Corneal transplantation has a high success rate, especially when performed for appropriate indications. Many patients experience significant improvement in vision and comfort once healing stabilises. Outcomes vary depending on underlying condition and transplant type.
Eye Transplant Cost in India
The estimated cost of an eye transplant in India ranges from Rs. 25,000 to Rs. 1.5 lakh, depending on the technique and hospital.
Typical cost components include:
- Surgical procedure and hospital charges
- Donor cornea processing
- Medications and eye drops
- Follow-up consultations
Pre-Transplant Evaluation Checklist
Before surgery, patients undergo:
- Comprehensive eye examination
- Corneal imaging and thickness measurement
- Vision testing
- Eye pressure assessment
- Infection screening
Specialist Expertise Matters
Corneal transplantation demands precision and experience. The surgeon’s expertise with different transplant techniques directly affects graft survival and visual outcome. Choosing a specialised eye centre ensures better coordination of surgery and long-term care.
