- A British team of university researchers have created the first ever 3D-printed human corneas.
- The corneas are made from a newly invented 'bio-ink' combining stem cells, alginate and collagen.
- New corneas can be scanned and printed in 10 minutes.
Scientists at Newcastle University in the UK have successfully 3D-printed the first human corneas.
Experimental Eye Research reports the team mixed stem cells from a healthy donor cornea with alginate and collagen to create a "bio-ink".
Using a simple low-cost 3D bio-printer, the bio-ink was extruded in concentric circles to form the shape of a human cornea — in less than 10 minutes.
The stem cells were then shown to grow. And the team also showed how the corneas could be grown to match a patient's unique specifications by scanning their eye first to determine the correct size and shape for the printed tissue.
Corneal blindness is estimated to threaten up to 10 million people worldwide, with another five million suffering total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease.
