Purpose
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.

Primary Outcome Measures:
- Changes in corneal thickness [ Time Frame: measured at week 1, 4, 8, 12, 16, 24, 36, 52 ] [ Designated as safety issue: No ]Corneal thickness measured by OCT at 1, 3, 6, and 12 o'clock surrounding the K-Pro front plate
Secondary Outcome Measures:
- Lack of sterile ulcers via slit lamp [ Time Frame: post op day 1, week 1, 4, 8, 12, 16, 24, 36, 52. ] [ Designated as safety issue: No ]
- Ocular safety [ Time Frame: measured at day 1, and week 1, 4, 8, 12, 16, 24, 36, 52 ] [ Designated as safety issue: Yes ]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 ] [ Designated as safety issue: Yes ]incidence and severity of systemic adverse events during the study (clinical laboratory, adverse events spontaneously reported).
