Impact of pretransplant fine-needle corneal vessel coagulation combined with subconjunctival bevacizumab injection on corneal allograft survival after high-risk penetrating keratoplasty. Kaplan-Meier curves depicting the estimated probabilities of rejection-free corneal graft survival after penetrating keratoplasty. Estimated probabilities of rejection-free corneal graft survival were 92.9% after 1 y (number at risk: 23), 78.4% after 2 y (number at risk: 9), and 78.4% after 3 y (number at risk: 3) for all study eyes (non–HLA-matched and HLA-matched keratoplasties) (A) and 95.8% after 1 y (number at risk: 18), 75.8% after 2 y (number at risk: 6), and 75.8 after 3 y (number at risk: 2) for eyes only with non–HLA-matched keratoplasties (B). Mean follow-up time: 560 days; range: 59–1095 days. Vertical dashes indicate censored observations. CI, confidence interval.
