The term "eye transplant" is sometimes used loosely by patients to mean any transplantation procedure involving the eye. In strict medical terms, a whole-eye transplant (transplanting the entire globe from a donor) is not currently performed anywhere in the world — the optic nerve cannot yet be reconnected to the brain after sectioning, meaning that a transplanted whole eye would not provide vision. However, major advances in biomedical research (including vascularised composite allotransplantation research programmes in the USA) mean that partial or modified eye transplantation may eventually become possible.

What is routinely and successfully performed is the transplantation of individual ocular tissues — the cornea, the sclera (the white outer wall of the eye), the ocular surface (limbal stem cells), and, in experimental contexts, retinal pigment epithelium cells. Corneal transplantation is by far the most common and most clinically mature of these procedures. Scleral patch grafting reconstructs defects in the scleral wall caused by trauma, thinning, or previous surgery. Limbal stem cell transplantation restores the corneal surface in patients with severe ocular surface disease (chemical burns, Stevens-Johnson syndrome, ocular cicatricial pemphigoid) where the stem cells responsible for maintaining the corneal epithelium have been destroyed.

India has the infrastructure, the expertise, and the eye banking system to perform all of these procedures at world-class standards. GAF Healthcare partners with NABH-accredited eye centres that have active programmes in corneal transplantation, scleral grafting, and limbal stem cell transplantation.

Types of Ocular Tissue Transplantation

Corneal Transplantation (Keratoplasty) is the most performed ocular transplant globally. The cornea — the clear front window of the eye — can be transplanted in full thickness (penetrating keratoplasty, PK) or in selective layers (lamellar keratoplasty: DALK for the anterior layers, DMEK/DSAEK for the posterior endothelial layer). Corneal grafts use donor tissue from the eye banks, processed and quality-tested to rigorous standards. India's eye banks perform over 25,000 corneal transplants per year.

Scleral Patch Grafting uses donor scleral tissue to repair defects in the scleral wall (the white of the eye). Indications include scleral thinning after trabeculectomy (glaucoma surgery), scleral necrosis, necrotising scleritis, scleral perforation from trauma, and as a tectonic patch to seal corneal perforations when corneal graft tissue is not available or appropriate. The graft is sutured over the defect to restore the structural integrity of the eye wall.

Limbal Stem Cell Transplantation (LSCT) replaces the limbal stem cells — located at the junction of the cornea and sclera — that maintain the corneal epithelial surface. When these cells are destroyed by chemical burns, thermal injuries, Stevens-Johnson syndrome, or chronic contact lens overwear, the conjunctiva grows over the corneal surface (conjunctivalisation), causing chronic pain, photophobia, and profound vision loss. LSCT uses donor limbal tissue (from a cadaveric eye bank or from the healthy fellow eye of the patient) to repopulate the limbal stem cell niche. Once stem cells are re-established, the corneal surface can be reconstructed, often followed by corneal transplantation to restore vision. LSCT requires systemic immunosuppression when allogeneic (donor) tissue is used.

Amniotic Membrane Transplantation uses donated placental amniotic membrane — processed and preserved by eye banks — as a biological bandage and scaffold for corneal and conjunctival surface reconstruction. It is not a "transplant" in the full sense but is widely used in managing chemical burns, corneal perforations, pterygium surgery, Stevens-Johnson syndrome, and persistent corneal epithelial defects.

Ocular Tissue Transplantation Procedure

The specific surgical approach depends entirely on the tissue being transplanted and the indication. All procedures are performed in an operating theatre under microscopic magnification, using micro-surgical instruments and sutures as fine as 10-0 nylon (thinner than a human hair). Most are performed under local anaesthesia with sedation; general anaesthesia is used for children and as required.

Corneal transplantation (PK, DALK, DSAEK, DMEK) procedures are described in detail in the dedicated Cornea Transplant section. The surgeon selects the technique most appropriate for the nature and depth of the patient's corneal disease.

For Scleral Patch Grafting: the area of scleral thinning or perforation is prepared and measured; donor scleral tissue is cut to size and sutured securely over the defect with non-absorbable sutures. The conjunctiva is then mobilised and sutured over the patch to cover it. The procedure takes 60–90 minutes.

For Limbal Stem Cell Transplantation: if autologous (using the patient's own healthy eye) — a 2–3 clock-hour strip of limbal tissue including epithelium and underlying limbal stroma is excised from the healthy eye and transplanted onto the diseased eye's limbal region. If allogeneic (using donor tissue) — limbal tissue from a cadaveric donor is transplanted; the patient requires systemic immunosuppression (low-dose cyclosporin or tacrolimus) to prevent rejection. Alternatively, ex-vivo expanded limbal stem cells (cultured in the laboratory on an amniotic membrane carrier) can be used, minimising the amount of tissue taken from the donor site; this technique is available at select centres in India.

Procedure Steps

1. Detailed ocular surface and anterior segment examination; anterior segment OCT; rose bengal or fluorescein staining of the ocular surface
2. Assessment of the fellow eye (for autologous LSCT) or tissue matching (for allogeneic LSCT)
3. Anaesthesia and sterile preparation
4. Preparation of recipient site — removal of conjunctivalised pannus or diseased tissue from corneal surface
5. Donor tissue prepared and transplanted to the recipient site with fine sutures
6. Amniotic membrane overlay applied as a bandage in some cases
7. Bandage contact lens applied for ocular surface procedures; shield placed overnight
8. Systemic immunosuppression initiated for allogeneic LSCT; steroid drops commenced

Ocular tissue transplantation procedures in the USA typically cost $10,000–$25,000 including tissue procurement, surgery, and hospital stay. In India, equivalent procedures cost $2,500–$6,000 all-inclusive. The cost difference reflects lower institutional overheads in India rather than any difference in tissue quality, surgical technique, or clinical outcome. GAF Healthcare provides transparent, itemised cost estimates before any commitment.

India's eye banks are governed by the Transplantation of Human Organs and Tissues Act (THOTA), which mandates quality standards for donor screening, serology testing, corneal evaluation, and tissue storage. Tissue from NABH-accredited eye banks meets international standards comparable to European and American eye bank accreditation (EBAA/EEBA standards).

Recovery & Follow-up

Recovery varies by procedure type. Corneal transplant recovery is described in detail in the dedicated Cornea Transplant section. Scleral patch grafting patients typically have a comfortable recovery over 2–4 weeks; the patch becomes incorporated into the sclera over months and does not require removal.

Limbal stem cell transplantation recovery is longer — 3–6 months to see meaningful improvement in ocular surface health, and often 12–18 months until corneal clarity improves sufficiently to consider a corneal transplant (which is performed as a second stage, once the stem cells are established). During this period, topical lubricants, low-dose steroids, and — for allogeneic cases — systemic immunosuppression are continued.

The common thread across all ocular tissue transplantation recoveries is the need for meticulous, long-term use of prescribed drops, regular monitoring, and patient-reported vigilance for early rejection or complication signs.

Recovery Tips

• Use all prescribed steroid, antibiotic, lubricant, and immunosuppressive drops or tablets strictly as directed
• Protect the eye from trauma at all times — a shield at night and glasses during the day are essential
• Avoid contact sports and swimming for at least 3 months after surgery
• Attend all follow-up appointments punctually — ocular surface conditions can deteriorate rapidly without monitoring
• Report immediately any new pain, redness, or vision change
• Avoid any exposure to chemical irritants, smoke, or dusty environments during recovery
• If on systemic immunosuppression (cyclosporin/tacrolimus), have regular blood tests to monitor drug levels and kidney function

Risks & Complications

Risks vary by procedure. Corneal graft rejection is detailed in the Cornea Transplant section. Scleral grafting risks include suture reactions, graft thinning or necrosis, and infection; these are uncommon with appropriate surgical technique and postoperative care. Limbal stem cell transplantation risks include rejection (particularly for allogeneic LSCT — the rejection rate is 20–40% without adequate immunosuppression), failure of stem cell engraftment, and in autologous cases, a risk of limbal deficiency in the donor eye (minimised by taking no more than 2–3 clock hours of tissue from any one eye).

All ocular tissue transplantation procedures are performed at a small risk of infection (endophthalmitis), IOP elevation, and cataract development. These risks are managed by careful surgical technique, post-operative monitoring, and appropriate use of steroid and IOP-lowering medications.

Why GAF Healthcare

GAF Healthcare connects international patients with India's most experienced ocular surface and anterior segment specialists. We ensure that every patient receives a thorough pre-operative assessment, including anterior segment OCT, ocular surface grading (using the Dua-Forrester classification for limbal stem cell deficiency), and a realistic discussion of expected outcomes before surgery is planned. Our coordinators manage travel, accommodation, tissue scheduling, and post-discharge handover to a local ophthalmologist who can manage ongoing drops, suture removal, and long-term monitoring.

Frequently Asked Questions

Is a whole-eye transplant possible?

Not yet. A complete whole-eye transplant — where a donor eye is transplanted and provides vision — is not currently possible because the optic nerve cannot be reconnected to the brain after sectioning. Research in vascularised composite allotransplantation and nerve regeneration is ongoing, but whole-eye transplantation is still many years away from clinical application. What is possible today is the transplantation of individual ocular tissues: corneas, sclera, and limbal stem cells.

I had a chemical burn to my eye years ago and was told I needed a transplant. What type?

Chemical burns — particularly alkali burns — destroy the limbal stem cells and cause conjunctivalisation of the corneal surface. The appropriate treatment is limbal stem cell transplantation (LSCT) to restore the stem cell population, followed by corneal transplantation once the surface is stable. The sequence and type of surgery depends on the severity of the burn (graded I–IV by the Roper-Hall classification), the degree of limbal stem cell deficiency, and the health of the fellow eye. A detailed assessment by a corneal specialist is the first step.

How long does ocular tissue transplantation last?

Corneal grafts: 10–20+ years with proper steroid maintenance and regular follow-up (DMEK grafts have the best longevity). Scleral patches: permanent — they integrate into the scleral wall and do not need replacement. Limbal stem cells: ideally permanent once successfully engrafted, though allogeneic grafts can fail (reject) over time, particularly if immunosuppression is stopped.
