Current Primary Outcome Measures ICMJE; (submitted: June 28, 2017)	Changes in Corneal Thickness at 1 Millimeter [ Time Frame: measured at week 4, 6, 26, 32, 52 ]The average carrier graft thickness over the first year of postoperative follow-up. The corneal thickness was measured at each visit using AS-OCT imaging 1 mm away from the KPro stem at 3, 6, 9, and 12 o'clock. The individual corneal thickness measurements (3, 6, 9, and 12 o'clock) where then averaged. The average corneal thickness measurements for week 4, 6, 26, 32 and 52 are reported below.; Changes in Corneal Thickness at 2 Millimeter [ Time Frame: measured at week 4, 6, 26, 32, 52 ]The average carrier graft thickness over the first year of postoperative follow-up. The corneal thickness was measured at each visit using AS-OCT imaging 2 mm away from the KPro stem at 3, 6, 9, and 12 o'clock. The individual corneal thickness measurements (3, 6, 9, and 12 o'clock) where then averaged. The average corneal thickness measurements for week 4, 6, 26, 32 and 52 are reported below.
Original Primary Outcome Measures ICMJE; (submitted: April 19, 2012)	Changes in corneal thickness [ Time Frame: measured at day 1, and week 1, 4, 8, 12, 16, 24, 36, 52 ]; Corneal thickness measured by OCT at 1, 3, 6, and 12 o'clock surrounding the K-Pro front plate

Current Secondary Outcome Measures ICMJE; (submitted: June 28, 2017)	Number of Occurrences of Vitritis (Sterile or Infectious) Ulcers [ Time Frame: post op week 52 ]Number of occurrence of vitritis (sterile or infectious) ulcers. Incidences of ulcers were collected by way of slit lamp photography from time of surgery to final visit.; 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 Measures ICMJE; (submitted: April 19, 2012)	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).

Descriptive Information
Brief Title ICMJE	Use of Cross-linked Donor Corneas as Carriers for the Boston Keratoprosthesis
Official Title ICMJE	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 Type ICMJE	Interventional
Study Phase	Phase 1; Phase 2
Study Design ICMJE	Intervention Model: Single Group Assignment; Masking: None (Open Label); Primary Purpose: Treatment
Condition ICMJE	Chemical Injuries; Unspecified Complication of Corneal Transplant; Autoimmune Diseases; Ocular Cicatricial Pemphigoid; Stevens Johnson Syndrome; Lupus Erythematosus, Systemic; Rheumatoid Arthritis; Other Autoimmune Diseases
Intervention ICMJE	Drug: Riboflavin; Used to treat donor cornea before implantation; Other Name: Riboflavin (vitamin B2) 0.1% solution
