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

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 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.

Secondary Outcome Measures:

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).

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.
