According to foreign media reports, human corneas have successfully been 3D printed for the first time by scientists at Newcastle University inEngland.
By mixing stem cells from a healthy donor cornea with alginate, a gel derived from seaweed, and collagen, researchers managed to create a "bio-ink" solution that can be printed.
This bio-ink then would be successfully expelled out of the printer in concentric circles in the shape of a cornea in less than 10 minutes, according to a paper published in Experimental Eye Research.
The 3D printed corneas will now have to undergo further testing but it is hoped the technique could be in regular use within five years.
The lead researcher Che Connon said the research could help with the worldwide shortage of corneas for transplant.
