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.

Рассмотрите местные варианты

  • •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.

Частые вопросы

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.
