Cornea Transplant (Keratoplasty)

What is a Cornea Transplant?

A cornea transplant surgery replaces part, or all, of the transparent front window of the eye with donor tissue that has been screened and prepared by an eye bank. In simple terms, keratoplasty meaning is the surgical replacement of diseased corneal layers to improve vision or preserve the eye’s integrity. Some people loosely refer to it as a cornea cell transplant. But surgeons actually transplant a very thin disc of tissue with specific layers and cells your eye needs. 

What happens during surgery, in brief:

• Anaesthesia is given so you do not feel pain.
• The surgeon removes only the damaged layer or, in some cases, the full thickness of the cornea.
• Donor tissue is positioned and secured, often with fine stitches or an air bubble, depending on technique.
• Most procedures take about 1 to 2 hours.

Indications of Cornea Transplant

Doctors consider indications of keratoplasty when other treatments, such as medication, glasses, contact lenses, or minor procedures, no longer help enough. Common reasons include:

• Keratoconus and other ectasias that thin and distort the cornea.
• Corneal scars after infections or eye injuries.
• Corneal dystrophies such as Fuchs’ endothelial dystrophy.
• Oedema or decompensation after prior eye surgery.
• Therapeutic indications for non-resolving ulcers or perforations.

Types of Cornea Transplant (Keratoplasty Types)

Your specialist recommends a technique that targets only the layer that has failed. This layer-specific approach speeds recovery and lowers rejection risk in suitable cases.

1) Penetrating Keratoplasty (PK)

• A full cornea transplant that replaces all layers.
• Preferred when scarring involves the entire thickness or when other techniques are unsuitable.
• Long track record with excellent long-term clarity when care is diligent.

2) Deep Anterior Lamellar Keratoplasty (DALK)

• Replaces the front and middle layers while preserving the endothelium if it is healthy.
• Often chosen for keratoconus or superficial scars because it reduces the risk of endothelial rejection.

3) Endothelial Keratoplasty

These techniques treat failure of the innermost cell layer that pumps fluid out of the cornea.

• DSEK/DSAEK: Transplants a thin layer of donor posterior stroma and endothelium.
• DMEK: Transplants only Descemet’s membrane and endothelium for the thinnest possible graft, often delivering sharper vision, though it can have a higher rate of early graft “slips” that need repositioning.

How do outcomes compare?
Evidence suggests strong graft survival with all methods. Large series and reviews report high five- to ten-year survival, with technique-specific nuances across centres. Choosing the “best” option is patient-specific and considers diagnosis, eye status, and surgeon expertise. 

Cornea Transplant Surgery Procedure

A keratoplasty procedure is carefully planned to maximise safety and results. The exact steps differ depending on whether you are having a full cornea transplant or a layer-specific graft.

Pre-operative preparation

• Detailed eye examination, including corneal imaging and measurements.
• Screening for other conditions like glaucoma or retinal disease.
• Arranging suitable donor tissue through the network of eye donation programmes and eye banks.

During surgery

• Most surgeries are performed under local anaesthesia. However, general anaesthesia may be used for children or complex cases.
• The surgeon removes the diseased corneal tissue with a precision blade or femtosecond laser.
• Healthy donor tissue is positioned. Depending on the technique, very fine nylon sutures or an air bubble may hold the graft in place.
• Cornea transplant surgery time is usually between one and two hours. But it can vary with case complexity.

After the operation

• An eye pad or shield protects the eye.
• Initial recovery is in a monitored setting until the patient is stable.
• Discharge often happens within a day, though follow-up visits are crucial.

Before and Aftercare of Cornea Transplant

The journey to clear vision involves careful steps before and after surgery. Once these stages are understood, patients can better prepare for the process, mentally and physically.

Before surgery

• Medical readiness: Your doctor may order blood tests, corneal scans, and systemic evaluations to ensure your body is ready for surgery.
• Medication adjustments: Some blood-thinning medicines might need to be paused. Always follow your ophthalmologist’s advice.
• Lifestyle preparation: Patients are advised to maintain healthy sleep and nutrition patterns for optimal healing.
• Counselling: Doctors explain realistic outcomes, including that vision may improve gradually rather than instantly.

   

After surgery

• Immediate care: Eye shields protect from accidental rubbing. Use prescribed antibiotic and steroid drops at specific intervals to reduce infection and rejection risk.
• Activity restrictions: Avoid swimming, dusty environments, and strenuous exercise until your doctor confirms it is safe.
• Diet and hydration: While no special diet is required, staying well-hydrated and consuming vitamin-rich foods may support faster healing.
• Follow-up visits: Typically scheduled one day, one week, one month, and then at regular intervals. These allow doctors to monitor healing and stitch stability.
• Vision changes: Vision may appear blurry in the first few weeks. Gradual improvement is expected. But clarity can take months, depending on the graft type.

Cornea transplant healing time in detail:

• Endothelial keratoplasty: Many patients notice significant clarity in 4–8 weeks, though vision may keep improving over six months.
• Lamellar keratoplasty (DALK): Stabilisation takes about six months to a year.
• Penetrating keratoplasty (PK): Complete healing often requires 12–18 months. After which, stitches may be selectively removed to improve corneal shape.

Emotional readiness is just as important. Some patients feel anxious if recovery seems slow. The surgical team’s counselling and reassurance help boost morale.

Average Cornea Transplant Cost in India

The cornea transplant cost in India is influenced by multiple factors.

• Hospital and city: Costs in metro cities like Bengaluru, Delhi, or Mumbai are higher than in smaller towns due to infrastructure and staff expenses.
• Type of keratoplasty:
  • Penetrating keratoplasty: ₹50,000 – ₹90,000.
  • DALK: ₹70,000 – ₹1,20,000.
  • Endothelial keratoplasty (DSEK/DMEK): ₹80,000 – ₹1,50,000.
• Additional expenses: Postoperative medications, special imaging, and longer follow-up schedules may increase overall cost.

Insurance coverage
Some insurance plans cover part or all expenses for cornea transplant surgery. Patients should check if “major eye surgeries” or “organ/tissue transplant” clauses apply.

Government and NGO support

• Schemes under the National Programme for Control of Blindness (NPCB) subsidise surgeries in select hospitals.
• NGOs and charitable trusts often sponsor surgeries for underprivileged patients, making the procedure more accessible.

Thus, while the cornea transplant cost in India varies widely, support options exist to make treatment more affordable. At Nethradhama, transparent billing and financial counselling help patients plan confidently.
