The cornea is the eye's clear front window — a precisely curved, five-layered transparent structure that accounts for roughly two-thirds of the eye's total refracting power. When the cornea becomes scarred, oedematous, distorted, or diseased, vision deteriorates dramatically. In many cases, corneal transplantation — replacing the diseased tissue with healthy donor cornea — is the only way to restore functional sight.
India is uniquely positioned to offer world-class corneal transplantation. The country has over 900 eye banks registered with the National Eye Bank of India, more than any other country, and several of them — the Sankara Nethralaya Eye Bank, the Eye Bank Association of India's network, and the L V Prasad Eye Institute's LVPEI Eye Bank — operate to the highest international standards of donor screening, corneal evaluation, and tissue processing. India's corneal surgeons have pioneered lamellar keratoplasty techniques that selectively replace only the diseased layers of the cornea, preserving healthy host tissue and dramatically improving recovery times and graft survival.
For international patients, India offers corneal transplantation at 60–75% below the cost of comparable procedures in the USA or UK, without compromise in surgical technique, tissue quality, or postoperative care. GAF Healthcare's partner centres in Chennai, Hyderabad, Bengaluru, and Mumbai perform hundreds of corneal transplants each year and maintain prospective graft survival databases.
Types of Corneal Transplant
Modern corneal transplantation has evolved well beyond the traditional full-thickness graft. Surgeons now select from several techniques, each matched to the specific layer and type of corneal disease.
Penetrating Keratoplasty (PK) replaces the full thickness of the cornea — all five layers — with an equivalent-sized disc of donor tissue, typically 7.5–8.5 mm in diameter. PK is used when disease or scarring involves multiple layers and cannot be treated with selective lamellar surgery. Despite a longer recovery time (up to 12–18 months for full stabilisation) and a higher risk of rejection compared to lamellar techniques, PK remains the gold standard for certain conditions such as full-thickness corneal scars, keratoconus with deep scars, and failed previous grafts.
Deep Anterior Lamellar Keratoplasty (DALK) replaces the anterior stroma while preserving the patient's own endothelium and Descemet's membrane. Because the host endothelium is retained, the risk of immune-mediated graft rejection is near-zero. DALK is the preferred operation for keratoconus, anterior stromal scars, and corneal dystrophies that spare the endothelium.
Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) and Descemet's Membrane Endothelial Keratoplasty (DMEK) replace only the posterior endothelial layer of the cornea — the cellular monolayer responsible for keeping the cornea clear. These posterior lamellar techniques are used for Fuchs' endothelial dystrophy and pseudophakic bullous keratopathy (corneal oedema after cataract surgery). DMEK uses only the Descemet membrane and endothelial cells (approximately 10–15 microns thick), offers faster visual recovery, lower rejection rates (less than 1%), and better final visual acuity than DSAEK, but is technically more demanding.
Conditions Treated with Corneal Transplant
Keratoconus is the most common indication for corneal transplantation in India and worldwide. It is a progressive, non-inflammatory condition in which the cornea thins and adopts a conical shape, causing irregular astigmatism and progressive vision loss that cannot be fully corrected with glasses or soft contact lenses. When rigid contact lens tolerance is lost or the cornea becomes too steep or thin for safe lens fitting, DALK or PK restores vision.
Fuchs' endothelial corneal dystrophy causes progressive loss of endothelial cells, resulting in corneal oedema and blurred vision — DMEK or DSAEK is the surgical treatment. Bullous keratopathy (corneal swelling after cataract surgery or trauma), corneal scars from bacterial or viral keratitis (including herpes simplex virus corneal disease), chemical injuries, and corneal dystrophies (macular, lattice, granular, stromal) are other common indications.
Corneal transplantation is considered when the patient's vision is significantly impaired, the patient is symptomatic (pain from bullae in bullous keratopathy, halos, glare, difficulty with daily activities), and alternative treatments such as rigid contact lenses, corneal collagen cross-linking (for keratoconus), or superficial keratectomy have failed or are not appropriate.
Corneal Transplant Procedure
Corneal transplantation is performed under local anaesthesia (peribulbar block) with intravenous sedation in most adult patients; general anaesthesia is used for children and very anxious adults. The procedure is typically 60–120 minutes depending on the technique.
For Penetrating Keratoplasty: a trephine (circular cutting instrument) removes a full-thickness disc from the central cornea; an equivalent disc of donor tissue is sutured in place using a single running 10-0 nylon suture or sixteen interrupted sutures. The sutures are left in place for 12–18 months to allow the graft to heal and stabilise before the astigmatism pattern is optimised by selective suture removal.
For DALK: air or viscoelastic is injected beneath the stroma to separate the deep stroma from Descemet's membrane (the big-bubble technique developed by Anwar and Teichmann); the anterior stroma is dissected and removed; the donor anterior stroma (without endothelium) is sutured in place. Big-bubble DALK requires high technical skill and is most reliably performed by experienced corneal surgeons.
For DMEK/DSAEK: the patient's diseased endothelial layer is stripped through a small corneal incision; the donor endothelial graft is folded or rolled, inserted through the small incision, and unfolded in the anterior chamber, then held in position with an air bubble injected behind it. The patient must lie flat for 24–48 hours to allow the air bubble to press the graft against the host cornea while it adheres. No sutures are required for the graft itself.
Procedure Steps
- Pre-operative corneal topography, specular microscopy (endothelial cell count), and OCT anterior segment assessment
- Donor tissue quality assessed — endothelial cell density, clarity, and absence of disease confirmed by eye bank
- Anaesthesia administered; antiseptic preparation and sterile draping
- Trephination or lamellar dissection of host cornea; diseased tissue removed
- Donor graft prepared on artificial anterior chamber and sized or punched to match
- Graft positioned and secured (sutures for PK/DALK; air bubble for DMEK/DSAEK)
- Wound sealed and IOP checked; antibiotic and steroid drops instilled
- Day 1 review for IOP and graft apposition; extended postoperative topical steroid regimen begun

Cornea transplant surgery in the USA costs between $13,000 and $27,000 per eye including tissue procurement, surgical fee, anaesthesia, and hospital stay. In the UK, the NHS waiting list for corneal grafts is typically 12–24 months; private surgery costs £5,000–£12,000. In Germany, corneal transplant costs €8,000–€16,000. In India, the same procedures — using tissue processed to international eye bank standards — cost $2,000–$5,000 per eye all-inclusive.
The savings are real and do not reflect any compromise in tissue quality or surgical expertise. India's leading corneal surgeons trained at Moorfields Eye Hospital (London), Massachusetts Eye and Ear, and other world-class institutions. Many are internationally published researchers. The cost advantage arises from lower institutional overheads and a government policy of subsidised eye care that keeps private sector pricing competitive. GAF Healthcare provides detailed cost breakdowns before any commitment and handles the paperwork for donor tissue import and customs clearance when specialist grafts are required.
Recovery & Follow-up
Recovery after corneal transplantation is measured in months, not days. In the immediate post-operative period (first 2 weeks), the eye is red, light-sensitive, and vision may be significantly blurred. The visual blur after DSAEK and DMEK clears fastest — many patients achieve 20/40 or better within 1–3 months. DALK and PK have a longer recovery trajectory: vision fluctuates while sutures are in place and stabilises only after suture adjustment or removal, typically 12–18 months after surgery.
Topical steroid eye drops are the cornerstone of long-term aftercare. They are used intensively in the first weeks and then slowly tapered over months to years. Most corneal graft recipients continue on a low-dose topical steroid (such as prednisolone 0.1% once daily) indefinitely to prevent late endothelial rejection, which can occur years after a technically successful transplant. Missing steroid drops — or stopping them without medical advice — is the most common preventable cause of late rejection.
Graft rejection is the major long-term risk. Symptoms of rejection include a red eye, photophobia, reduced vision, and pain — any of these in the weeks or months after transplantation should prompt urgent review within 24 hours, as early treatment with intensive topical and systemic steroids can reverse most rejection episodes if initiated promptly.
Recovery Tips
- Use all prescribed steroid, antibiotic, and lubricant drops exactly as instructed — never reduce them without your surgeon's advice
- Protect the eye with a shield at night for 4–8 weeks and wear protective glasses during the day outdoors
- Avoid rubbing the eye at all costs — the graft wound takes 12–18 months to reach full strength
- Report any new redness, photophobia, or vision drop immediately — these are rejection warning signs
- Avoid swimming pools, hot tubs, and dusty environments for at least 2 months
- Regular follow-up with a local corneal specialist is essential — GAF Healthcare can arrange handover to a partner ophthalmologist in your home country
- Inform all future healthcare providers that you have a corneal graft — this affects anaesthetic eye drop choices and many routine assessments
Risks & Complications
Corneal graft rejection is the principal long-term risk. Approximately 10–20% of PK grafts experience at least one rejection episode within 5 years; DMEK has a rejection rate of less than 1%. Most rejection episodes can be reversed with prompt intensive topical steroid therapy. Persistent or repeated rejection leads to graft failure requiring re-transplantation.
Other risks include primary graft failure (the donor endothelium fails to function from the outset — rare, approximately 1–2%); elevated intraocular pressure (glaucoma) caused by topical steroids or altered trabecular drainage; suture-related complications (suture abscess, suture-induced astigmatism, suture breakage); infection; and post-keratoplasty astigmatism, which can be significant after PK and may require contact lens correction or laser refractive surgery after graft stabilisation.
Graft survival rates at GAF Healthcare's partner centres: 90% at 5 years for PK; 85–90% at 5 years for DALK; over 95% at 3 years for DMEK. These figures are prospectively tracked and are available for review on request.

For urgent cases such as corneal perforation or rapidly progressive corneal ulcers, we have emergency pathways that can have you in surgery within 48 hours.
Frequently Asked Questions
How long does a corneal transplant last?
DMEK grafts have a 5-year survival rate of over 95% and many last 20+ years with proper steroid maintenance. PK grafts have a 5-year survival rate of approximately 90% in uncomplicated cases; the survival rate declines with time and with re-transplantation. Regular follow-up and lifelong low-dose topical steroids are the most important factors in graft longevity.
Can I travel internationally after a corneal transplant?
For DMEK/DSAEK, most patients can fly home 7–10 days after surgery once the air bubble has been absorbed and the graft is confirmed adherent. For PK and DALK, flying is usually safe 1–2 weeks after surgery. You will need to carry your steroid and antibiotic eye drops in your hand luggage and have a plan for local ophthalmological follow-up in your home country. GAF Healthcare coordinates this handover as a standard part of its service.
Is there a long waiting list for cornea transplant in India?
Unlike the NHS in the UK (12–24 months wait) or many European public systems, India's private eye hospitals typically schedule corneal transplants within 1–4 weeks of confirmed surgical planning, depending on tissue availability. GAF Healthcare's partner eye banks maintain adequate tissue stocks for the most common procedures (PK, DSAEK, DMEK). Specialist tissue (e.g. pre-cut DMEK tissue) may require 2–3 weeks advance notice.
Can keratoconus be treated without a corneal transplant?
In early to moderate keratoconus, corneal collagen cross-linking (CXL) can halt progression and preserve the cornea for many years. Rigid gas-permeable (RGP) contact lenses or specialty scleral lenses can correct the vision distortion caused by the irregular cornea. When these measures fail — typically when contact lens tolerance is lost or the cornea becomes too steep or thin — DALK or PK is required. India's eye centres offer all of these treatments, and a corneal specialist can advise on the most appropriate stage-by-stage approach.
What are the signs of corneal graft rejection that I should watch for?
The classic warning symptoms are the four Rs: Redness (new-onset redness of the transplanted eye), Reduced vision (any unexplained drop in vision), photosensitivity (increased sensitivity to light), and pain. Any of these symptoms should prompt an urgent ophthalmological review within 24 hours — do not wait for a routine appointment. Early treatment with intensive topical steroids can reverse most rejection episodes completely.
