First human corneas 3D printed in the UK for blindness cure
In a first, researchers at UK's Newcastle University have 3D printed human corneas, the outermost layer of the eye. There is a significant shortage of corneas, with 10 million people worldwide requiring transplants to prevent corneal blindness, said researchers. Donor cornea stem cells were mixed with collagen to create the printable solution, which could provide an unlimited supply of corneas.
