Purpose: To identify donor and recipient factors, including eye bank tissue observations, predictive of operative complications in the Cornea Preservation Time Study.

Methods: One thousand three hundred thirty study eyes undergoing Descemet stripping automated endothelial keratoplasty for Fuchs dystrophy or pseudophakic/aphakic corneal edema were randomized to receive a donor cornea with preservation time (PT) of 0 to 7 days (N = 675) or 8 to 14 days (N = 655). Donor factors included demographics, prelamellar corneal and postlamellar lenticule dissection thickness, central endothelial cell density, and tissue processing time.

Purpose: To assess donor rim culture results and outcomes of ocular infections in the Cornea Preservation Time Study (CPTS).

Methods: Donor corneal rim cultures were optional. Donor characteristics were assessed for association with positive cultures using the Fisher exact test and Poisson regression analyses.

Objective: To determine whether the 10-year success rate of penetrating keratoplasty for corneal endothelial disorders is associated with donor age.

Design: Multicenter, prospective, double-masked clinical trial.

Participants: A total of 1090 participants undergoing penetrating keratoplasty at 80 sites for Fuchs' dystrophy (62%), pseudophakic/aphakic corneal edema (34%), or another corneal endothelial disorder (4%) and followed for up to 12 years.

Context: The request process for eye and tissue donation is different from the process that families of organ donors experience, but the research into eye/tissue-only decision making has been sparse.

Objective: To determine the concerns of families approached over the phone for eye/tissue donations and to study the impact of the donor registry on those decisions.

Design, Setting And Participants: Written instrument filled out by family services coordinators while speaking with families about donation via phone in the San Diego, California, area during 2011.

Purpose: To assess corneal thickness (CT) and correlation with graft outcome after penetrating keratoplasty in the Cornea Donor Study.

Methods: A total of 887 subjects with a corneal transplant for a moderate-risk condition (principally Fuchs dystrophy or pseudophakic corneal edema) had postoperative CT measurements throughout a 5-year follow-up time. Relationships between baseline (recipient, donor, and operative) factors and CT were explored.
