Corneal Diseases

Corneal transplantation, cross-linking, and advanced surface treatments

The cornea is the eye's clear front window, and diseases affecting it can severely impair vision. Modern treatments range from collagen cross-linking to strengthen keratoconic corneas, to advanced transplantation techniques like DMEK and DSAEK that replace only the affected layers. Chinese corneal centers offer these sophisticated procedures with excellent outcomes and significantly lower costs than Western countries.

Core Technologies

Collagen cross-linking (CXL) • DMEK (Descemet membrane) • DSAEK (endothelial) • PKP (full thickness) • Deep anterior lamellar (DALK) • Femtosecond laser assisted • OCT-guided surgery

Ideal Candidates

•Keratoconus progression (cross-linking)
•Fuchs' dystrophy with vision loss (DMEK/DSAEK)
•Corneal scarring affecting vision (PKP/DALK)
•Failed previous corneal transplants
•Corneal infections not responding to medication
•Bullous keratopathy causing pain

Corneal graft tissue availability excellent in major Chinese centers

Consider Home Country For

•Active corneal infections requiring intensive monitoring
•Patients needing very frequent post-op follow-up
•Those with one good eye requiring extra caution
•Cases requiring long-term immunosuppression management

Evidence: DMEK demonstrates 95%+ graft clarity at 2 years with rapid visual recovery. Cross-linking halts keratoconus progression in 95%+ of cases. PKP achieves 80-90% graft survival at 5 years.

Treatment Options

Corneal Cross-Linking (CXL)

Surgery

Best for:Progressive keratoconus, post-LASIK ectasia

Tech:Riboflavin + UV-A light strengthens corneal collagen

Advantage:Halts disease progression, avoids/delay transplant

1 hour, bandage contact lens 1 weekFrom $1,000 per eye

95%+ success stopping progression

DMEK (Endothelial Transplant)

Surgery

Best for:Fuchs' dystrophy, bullous keratopathy (endothelial failure)

Tech:Transplants only Descemet membrane and endothelium

Advantage:Fastest recovery, best vision, low rejection

45 minutes, air tamponadeFrom $3,000

Preferred for endothelial disease

DSAEK (Endothelial Transplant)

Surgery

Best for:Endothelial failure, complex cases unsuitable for DMEK

Tech:Transplants posterior lamella including stroma

Advantage:Easier technique than DMEK, good outcomes

45-60 minutesFrom $2,500

Established alternative to DMEK

PKP (Full Thickness Transplant)

Surgery

Best for:Deep scarring, advanced keratoconus, complex pathology

Tech:Full thickness donor cornea sutured in place

Advantage:Definitive for advanced disease

1-1.5 hoursFrom $3,000

Gold standard for complex cases

DALK (Deep Anterior Lamellar)

Surgery

Best for:Anterior scarring, keratoconus with healthy endothelium

Tech:Replaces front layers, preserves patient's endothelium

Advantage:Lower rejection risk than PKP

1.5-2 hoursFrom $3,000

Specialized anterior lamellar surgery

Amniotic Membrane Transplant

Surgery

Best for:Severe dry eye, persistent epithelial defects, ulcers

Tech:Biological bandage promotes healing

Advantage:Promotes healing, reduces scarring

30 minutesFrom $800

Adjunct for surface disease

Common Questions

How long does a corneal transplant last?

DMEK/DSAEK: 90%+ clear at 5 years. PKP: 80-90% at 5 years, 60-70% at 10 years. Rejection can occur years later but is treatable if caught early.

Is corneal transplant painful?

No pain during surgery (anesthesia). Mild irritation for 1-2 weeks. DMEK has fastest comfort recovery. PKP has suture-related discomfort until sutures removed (months later).

Will I still need glasses after corneal transplant?

Yes, likely. The goal is a clear graft. Astigmatism (especially after PKP) often requires glasses or contact lenses. Some patients need rigid gas permeable contacts for best vision.

How effective is cross-linking for keratoconus?

Cross-linking halts progression in over 95% of cases. Some patients also experience mild flattening and vision improvement. It does not reverse existing damage but prevents worsening.

What does corneal transplant or cross-linking cost in China for international patients?

Corneal transplant China cost (DMEK, DSAEK, PKP) and cross-linking for keratoconus are typically 50–60% lower than in the US or UK. Our partner centers have experienced corneal specialists and advanced microsurgery. Get a personalized quote via our cost calculator.
