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

This study is currently recruiting participants.

ClinicalTrials.gov Identifier:
NCT01582880
First received: April 10, 2012
Last updated: March 20, 2013
Last verified: March 2013
  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).
