Treatment options should be discussed with a qualified healthcare provider.
Penetrating Keratoplasty (Full-Thickness Transplant)
Complete corneal replacement with donor tissue restores structural integrity and optical clarity in end-stage keratoconus. This procedure is reserved for cases where other interventions cannot provide adequate visual rehabilitation.
Post-Transplant Contact Lens Fitting
Specialized lens fitting optimizes visual outcomes after corneal transplantation, addressing residual astigmatism and irregularity. Custom prosthetic lenses may be necessary for optimal optical rehabilitation.
Additional treatment options
Graft Surveillance Protocol
Intensive post-operative monitoring detects early signs of rejection, infection, or suture complications. Regular endothelial cell counts and topography assess long-term graft health and stability.
monitoringNutritional Support for Corneal Health
Dietary supplementation with omega-3 fatty acids, vitamin D, and antioxidants supports ocular surface health and may aid healing post-operatively. General nutritional guidance promotes overall wellness during treatment journey.
complementaryChronic Vision Loss Adaptation Support
Specialized counseling and support groups help patients cope with significant visual impairment during advanced disease phases. Skills training and assistive technology assessment maximize functional independence.
