The goal of this study is to investigate whether using bevacizumab (Avastin®) is both safe and effective at decreasing the likelihood of a high-risk corneal graft rejection. Patients who are "high-risk" for rejection have blood vessels growing from the white of the eye into the cornea (clear, front region of the eye). The medication is used at the time of surgery and in the weeks following surgery. Participants have a 50/50 chance at receiving the active study medication or a placebo medication.

Primary | Endothelial Rejection Rate | Endothelial rejection rates in patients in the treatment group and the control group were calculated using the Kaplan-Meier survival curve. The Kaplan-Meier/product limit estimator is a non-parametric statistical test used to show the probability of an event occurring at a given time interval. The Kaplan-Meier estimator is used to show what the probability of corneal transplant rejection (and therefore transplant survival) after administration of the active treatment or control. | 12 Months | |
Primary | Number of Participants Experiencing Ocular Adverse Events | Incidence and severity of ocular adverse events during the study (based on ophthalmic examination and subject self-reporting). | 12 months | |
Primary | Incidence of Systemic Adverse Events | Incidence and severity of systemic adverse events during the study (based on physical examination, subject self-reporting, and changes in vital sign). | 12 Months |
