Use of Cross-linked Donor Corneas as Carriers for the Boston Keratoprosthesis
The Use of Riboflavin/Ultraviolet A Cross-linked Human Donor Corneas as Carriers for the Boston Keratoprosthesis
The purpose of the pilot study is to test the efficacy and safety of riboflavin/Ultraviolet A (UVA) cross-linked human donor corneas as carriers for the Boston Keratoprosthesis (Boston KPro) in patients with higher risk for corneal melting (keratolysis).
The corneal cross-linking technique has been shown to strengthen the cornea and resist degradation by the body's own enzymes. The use of highly-resistant donor corneas is meant to eliminate the serious post-operative complication of corneal melting (keratolysis) that repeatedly occurs in Boston KPro patients with severe ocular burns, autoimmune and cicatrizing diseases.
Interventional
Phase 1
Phase 2
Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
  • Chemical Injuries
  • Unspecified Complication of Corneal Transplant
  • Autoimmune Diseases
  • Ocular Cicatricial Pemphigoid
  • Stevens Johnson Syndrome
  • Lupus Erythematosus, Systemic
  • Rheumatoid Arthritis
  • Other Autoimmune Diseases
Drug: Riboflavin
Used to treat donor cornea before implantation
Other Name: Riboflavin (vitamin B2) 0.1% solution
Experimental: Riboflavin Cross-linked donor cornea
the donor cornea used as a carrier for the Boston Keratoprosthesis will undergo crosslinking treatment before being trephined and prepared for implantation with the Keratoprosthesis.
Intervention: Drug: Riboflavin
