History of Changes

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).

Primary Outcome Measures:

Changes in corneal thickness [ Time Frame: measured at 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

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. ]
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).

Estimated Primary Completion Date:	April 2017 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
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.	Drug: Riboflavin Used to treat donor cornea before implantation Other Name: Riboflavin (vitamin B2) 0.1% solution

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.
