Brief Title

Use of Cross-linked Donor Corneas as Carriers for the Boston Keratoprosthesis

Official Title

The Use of Riboflavin/Ultraviolet A Cross-linked Human Donor Corneas as Carriers for the Boston Keratoprosthesis

Brief Summary

      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).

Detailed Description

      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.

Study Phase

Phase 1/Phase 2

Study Type


Primary Outcome

Changes in Corneal Thickness at 1 Millimeter

Secondary Outcome

 Number of Occurrences of Vitritis (Sterile or Infectious) Ulcers

Study Arms / Comparison Groups

 Riboflavin Cross-linked donor cornea
Description:  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.
