Clinical Trial: Use of Cross-linked Donor Corneas as Carriers for the Boston Keratoprosthesis
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional
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 Summary: 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.

Current Primary Outcome: Changes in corneal thickness [ Time Frame: measured at week 1, 4, 8, 12, 16, 24, 36, 52 ]
Original Primary Outcome: Changes in corneal thickness [ Time Frame: measured at day 1, and week 1, 4, 8, 12, 16, 24, 36, 52 ]
Current Secondary Outcome:
- Lack of sterile ulcers via slit lamp [ Time Frame: post op day 1, week 1, 4, 8, 12, 16, 24, 36, 52. ]
- Ocular safety [ Time Frame: measured at day 1, and week 1, 4, 8, 12, 16, 24, 36, 52 ]incidence and severity of ocular adverse events during the study (ophthalmic examination, adverse events spontaneously reported)
- Systemic safety [ Time Frame: measured at day 1, and week 1, 4, 8, 12, 16, 24, 36, 52 ]incidence and severity of systemic adverse events during the study (clinical laboratory, adverse events spontaneously reported).
Original Secondary Outcome: Same as current
