Keratoplasty is one of the most common grafts and penetrating keratoplasty is still the technique most used in the world, ahead of lamellar grafts, and is estimated to represent 70% of the total. Graft rejection is still the main cause of failure of this type of surgery, to the extent that nearly a third of all patients will in some way be affected by rejection in due course. Numerous risk factors for rejection have been identified, whether related to the donor, the recipient, or the surgical procedure itself. In addition, many of the studies performed have used univariate analysis only, and yet there is a strong case for multivariate analysis, given the wide range of factors that need to be examined. This study seeks to analyze the rejection rates and the survival of penetrating keratoplasty for a group of patients from Montpellier Hospital (France).
