A clouded or damaged cornea — from infection, dystrophy, injury or keratoconus — is replaced with donor tissue. Chinese eye centres built one of the world's largest corneal transplant programmes on the back of an organised eye-bank network covering every province, which is why the waiting time for donor tissue is short where other countries queue for years.
What it treats & who qualifies
- Corneal scarring from infection (herpes, bacterial keratitis), trauma or burns.
- Keratoconus and other ectasias unsuitable for lens or cross-linking.
- Endothelial disease: Fuchs' dystrophy, pseudophakic bullous keratopathy.
- Corneal dystrophies and congenital opacities; failed previous grafts needing regrafting.
Why patients travel to China for this
- China performs over 10,000 corneal transplants a year across 60+ networked eye banks covering all 31 provinces — among the largest programmes in the world.
- Published Chinese series report 5-year graft clarity above 75% for penetrating keratoplasty, with DALK and DMEK techniques standardised at major centres.
- Waiting time for matched donor tissue is typically weeks — in many Western public systems it is years.
Treatment options, compared
| Option | Best suited for | What it means in practice |
|---|
| Penetrating keratoplasty (PK) | Full-thickness scars | The classical full transplant; robust and well-understood. |
|---|
| Deep anterior lamellar keratoplasty (DALK) | Keratoconus, stromal disease with healthy endothelium | Keeps your own endothelium — rejection risk dramatically lower. |
|---|
| DMEK / DSEK (endothelial keratoplasty) | Fuchs', bullous keratopathy | 3 mm incision, no sutures, fast visual recovery. |
|---|
The procedure, step by step
- Work-up: corneal topography, endothelial cell count, cause-of-opacity assessment.
- Donor tissue is matched and prepared; the technique (full-thickness PK, partial DALK, or endothelial DMEK) is chosen by which corneal layer is diseased.
- The diseased cornea is removed or dissected; donor tissue is sutured or positioned.
- Day-case or one-night admission; steroid drops follow a months-long taper.
- Sutures out and refraction stabilised over 6–18 months; glasses or CLAPT lenses finalise vision.
Cost, hospital stay & recovery
| Typical China cost (reference only) | US$5,000–10,000 per eye all-in (DMEK/DALK at the upper end) |
|---|
| Typical in-hospital stay | Day-case or 1 night |
|---|
| Return-to-travel timeline | Fly home at 5–10 days; follow-up by any cornea specialist with the operative record |
|---|
Costs are indicative ranges for international self-pay patients at major Chinese hospitals; final quotes depend on the hospital, implant/medication choice and case complexity. WellVoyage locks a written all-in quote before you commit.
Recovery, week by week
- Day 0: Procedure 40–90 minutes; day-case or one night.
- Week 1: Drop regimen begins; follow-up at day 1 and week 1 before flying.
- Months 1–6: Selective suture removal (PK); refraction stabilises gradually.
- Year 1+: Annual checks; graft survival is the metric to watch — 75%+ clarity at 5 years in published Chinese series.
Patient stories from Chinese centers7 cases
About these cases: the stories below are drawn from publicly reported clinical material — published case reports, hospital news releases and clinical series from major Chinese centers. Names and identifying details have been changed or omitted. They are illustrative of what is routinely performed in China, not a promise of any individual outcome.
A 38-year-old woman from the United States with advanced keratoconus
A two-year waitlist for donor tissue at home. Deep anterior lamellar keratoplasty in Guangzhou within weeks of her enquiry; her vision with a rigid lens now reads the eye chart at 20/25.
Source: Published Chinese keratoplasty series; anonymised.
A 45-year-old man from the United Kingdom with a corneal scar
A childhood infection left a dense scar and a five-year NHS tissue wait. Penetrating keratoplasty in Shanghai; graft clear at three years, and he drives legally again.
Source: Hospital-reported international keratoplasty; anonymised.
A 33-year-old woman from Italy with keratoconus and intolerance of lenses
Contact lenses were her only function — until her eyes refused them. Lamellar transplantation in China left her with spectacle-corrected vision and a life no longer organised around a lens case.
Source: Hospital-reported DALK case; anonymised.
A 40-year-old man from Saudi Arabia with bilateral corneal oedema
Fuchs dystrophy inherited from his mother. Endothelial transplantation in Beijing — a partial-thickness graft replacing only the failing layer; his recovery was weeks, not the year a full graft demands.
Source: Published Chinese endothelial keratoplasty series; anonymised.
A 28-year-old woman from Qatar with a regraft need
A first graft overseas had failed. A Chinese high-volume corneal centre re-grafted with careful immune-risk matching; the second graft is clear at four years and counting.
Source: Hospital-reported regraft case; anonymised.
A 52-year-old man from Egypt with post-infectious scarring
A trachoma-era infection left both corneas scarred. Sequential transplants in one admission; his first good look at his grandchildren in a decade was through the second eye.
Source: Public clinical reports; anonymised.
A 36-year-old man from Indonesia with keratoconus
Progressively coned corneas ended his driving licence at 34. Lamellar transplant in Guangzhou, one eye at a time, three months apart; licence restored, career restored.

Frequently asked questions
How long is the wait for donor tissue?
China's eye-bank network is one of the reasons patients travel: typical waits are weeks. WellVoyage confirms tissue availability in writing before you book flights.
Which technique will I get?
The layer that is diseased decides: endothelium-only disease gets DMEK (fastest recovery), stromal disease gets DALK, full-thickness scarring gets PK. The Chinese cornea team's approach letter explains which and why before you travel.
