Health status and patient satisfaction after corneal graft: results from the corneal transplant epidemiological study.

Purpose. To evaluate effects of corneal transplantation on the health-related quality of life and patients' satisfaction. Methods.

Risk factors for graft failure after penetrating keratoplasty: 5-year follow-up from the corneal transplant epidemiological study.

Purpose: To evaluate corneal graft survival over a 5-year period and to investigate whether factors related to the donor, eye bank practices, the recipient, surgery, and postoperative course influenced the outcome.

Methods: Nine hundred ninety-eight patients were randomly selected and monitored in the subsequent 3 years from a cohort of 4500 recipients who underwent penetrating keratoplasty between 2001 and 2004. Cox univariate regression analysis was used to select variables to be included in a multivariate Cox proportional hazards model with a backward selection procedure to identify potential risk factors for graft failure.
