Researchers make major breakthrough in eye health management
Researchers mixed stem cells from healthy donor cornea with alginate and collagen to create the 'bio-ink'.
A simple low-cost 3D bio-printer took less than ten minutes to print the corneas.
The technique could be used in the future to ensure an unlimited supply of the outermost layer of the eye.
The cornea plays an important role in focusing vision, but there is a significant shortage available for transplants.
Researchers say the 3D printed corneas will have to undergo further testing.
It will be several years before they could be used for transplants.
