Comparison of Small-incision Femtosecond Laser-assisted Intrastromal Keratoplasty and Lamellar Keratoplasty in Rhesus Monkeys Using Xenogenic Corneal Lamellae

摘要

Background: In our previous study, both allogeneic and xenogeneic small-incision femtosecond laser-assisted intrastromal keratoplasty were demonstrated to be safe and effective surgeries. Glycerol-dehydrated corneal lamellae could serve as alternative xenogeneic inlay grafts. However, these xenogeneic lamellae have not been explored in lamellar keratoplasty (LK). The immunoreactivity differences between corneal intrastromal xenotransplantation and xenogeneic LK have not been assessed.
