Cornea Donor Study - Full Text View

Purpose

The Cornea Donor Study (CDS) was designed as a prospective cohort study with the following objectives:

To determine whether the graft-failure rate over a 5-year follow-up period following corneal transplantation is the same when using corneal tissue from donors older than 65 years of age compared with tissue from younger donors.

To assess the relationship between donor/recipient ABO blood type compatibility and graft failure due to rejection.

To assess corneal endothelial cell density as an indicator of the health of the cornea and as a alternate outcome measure (in an optional Specular Microscopy Ancillary Study).

Secondary Outcome Measures:

endothelial cell density [ Time Frame: enrollment through end of follow up ] [ Designated as safety issue: No ]

Estimated Study Completion Date:	July 2013
Primary Completion Date:	December 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Active Comparator cornea from donor <66.0 years	Other: corneas assigned by donor age group A web-based computer program was used to select a cornea from those available at the eye bank that met the study eligibility criteria. The program randomly selected a cornea based on a two-level minimization procedure which attempted first to balance for each surgeon the number of corneas from donors >=66 and <66 years old and then, when possible, to balance among age subgroups of 10-35, 36-50, 51-65, 66-70, and 71-75 years. The assignment was made without regard to recipient age or any other subject characteristics.
