Purpose: The purpose of this study was to report trends in the prevalence of early graft failure after endothelial keratoplasty in the United States.
Methods: Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSAEK) graft volumes were collected from records maintained by 6 major eye banks in the United States from January 1, 2013, to December 31, 2018. The prevalence and presumed cause of early graft failures (defined as a graft with persistent edema or regrafted within 8 weeks after keratoplasty) each year were sourced from surgeon-reported adverse events.
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.
Purpose: To evaluate retrospectively whether the findings from the Cornea Donor Study (CDS) led to changes in the transplantation of corneas from older donors.
Methods: Eye banks in United States provided complete data on donor age and placement (domestic or international) for 86,273 corneas from 1998 to 2009. The data were analyzed by 3 periods, preceding CDS (1998-1999), during CDS (2000-2007), and after publication of CDS 5-year results (2008-2009), and separately for corneas placed within versus outside the United States.
Objective: To determine whether endothelial cell loss 5 years after successful corneal transplantation is related to the age of the donor.
Design: Multicenter, prospective, double-masked clinical trial.
Participants: Three hundred forty-seven subjects participating in the Cornea Donor Study who had not experienced graft failure 5 years after corneal transplantation for a moderate-risk condition (principally Fuchs' dystrophy or pseudophakic corneal edema).

Objective: To determine whether graft survival over a 5-year follow-up period using corneal tissue from donors older than 65 is similar to graft survival using corneas from younger donors.
Design: Multicenter prospective, double-masked, controlled clinical trial.
Participants: One thousand ninety subjects undergoing corneal transplantation for a moderate-risk condition (principally Fuchs' dystrophy or pseudophakic corneal edema); 11 subjects with ineligible diagnoses were not included.
