Researchers 3D-Print A Human Cornea, May Save Millions From Blindness

NEWCASTLE UPON TYNE, UK (CBS Local) – Researchers at Newcastle University in the United Kingdom have successfully created the first ever 3D-printed cornea, giving millions at risk of going blind new hope. British scientists combined human stem cells with a mixture of alginate and collagen to produce a “bio-ink” that can be used by a 3D printer. The durable yet flexible combination can reportedly be turned into the outer lens of the eye, which light passes through on its way to the retina in less than 10 minutes. “Our unique gel… 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,” Prof. Che Connon said in a university release. “Now we have a ready to use bio-ink containing stem cells allowing users to start printing tissues without having to worry about growing the cells separately.” Our Director of Research, Policy & Innovation, Dr Neil Ebenezer, said "This research highlights the significant progress that has been made in this area and this study is important in bringing us one step closer to reducing the need for donor corneas" https://t.co/xlE4iOum5K pic.twitter.com/ROaGZKOZxw — Fight for Sight (@fightforsightUK) May 30, 2018 The researchers say that their new creation may help over 15 million people who have gone blind or are at risk of losing their vision because of diseases, eye disorders or...
