The first human corneas have been 3D printed by scientists at Newcastle University.
It means the technique could be used in the future to ensure an unlimited supply of corneas.
Using a simple low-cost 3D bio-printer, the bio-ink was successfully extruded in concentric circles to form the shape of a human cornea. It took less than 10 minutes to print.
The stem cells were then shown to culture – or grow.
The scientists, including first author Ms Abigail Isaacson from the Institute of Genetic Medicine, Newcastle University, also demonstrated that they could build a cornea to match a patient’s unique specifications.
The dimensions of the printed tissue were originally taken from an actual cornea. By scanning a patient’s eye, they could use the data to rapidly print a cornea which matched the size and shape.
