Researchers at the University Of Newcastle have announced they’ve managed to 3D print corneas – the outermost part of the human eye. This is incredible, life-changing news for a lot of folks. Worldwide, 10 million people require surgery to prevent corneal blindness from diseases like trachoma. On top of this, almost 5 million are completely blind due to corneal scarring from accidents or illnesses. This high-tech method of producing corneas could end all that. It works by taking stem cells from a health donor’s cornea and mixing it together with a gel, creating what researchers have deemed “bio-ink.” “Our unique…
