Unbelievable! For the First Time Ever Scientists Created 3D-Printed Human Corneas at Newcastle University (VIDEO)

Scientists at Newcastle University in the UK say they’ve created the first 3D-printed human corneas. Using a combination of their unique “bio-ink” and cornea stem cells, they can print the corneas in under ten minutes. 

3D-technology that can save millions

Scientists from Newcastle University have developed a “bio-ink” that allowed them to successfully 3D print human corneas. On Wednesday, they published their proof-of-concept research in the journal Experimental Eye Research.

The cornea is the outermost layer at the front of the eye. If it’s damaged by either disease or injury, a person can suffer vision problems or even lose their sight. The only treatment for a non-functioning cornea is a cornea transplant. But even though more than 15 million people need donor corneas, just 44,000 transplants are done every year — the demand far outweighs the supply.

Newcastle University researchers have devised a groundbreaking experimental technique that could help millions on the corneal transplant waiting list. By using a simple 3D bio-printer, Professor of Tissue Engineering Che Connon and his team of scientists were able to combine healthy corneal stem cells with collagen and alginate (a type of sugar sometimes used in tissue regeneration) to create ‘bio-ink’ – a printable solution that enabled them to reproduce the shape of a human cornea in just 10 minutes.

“Many teams across the world have been chasing the ideal bio-ink to make this process feasible,” study co-author Professor Che Connon said in a statement. “Our unique gel — a combination of alginate and collagen — keeps the stem cells alive whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer.”

However, the study’s authors said it will likely take years for patients to actually start receiving 3D-printed corneas.
