Researchers from Newcastle University have made an amazing breakthrough by 3D printing the most advanced artificial cornea with human stem cells. It is estimated that this technology could potentially change millions of lives if properly developed. According to Laura Yan’s article in Popular Mechanics,
“The cornea is the protective, clear outer layer covering the eye. When it’s damage, it creates serious vision problems or can cause blindness. Currently, people with damaged corneas hope for healthy corneas transplants from deceased donors, but the need far exceeds the supply.”
The research team of engineers at Newcastle University published their detailed results in Experimental Eye Research. According to their results, the initial development of these 3D printed corneas came as quite the challenge. Because of the cornea’s distinct curvature, they had to use special cameras to photograph the eyeballs of a volunteer in order to make a 3D model. The team was then tasked with developing an ink that would be usable on a 3D printer. They achieved this by creating a bioink which wouldn’t compromise the 3D shape of the cornea. By adding these donor stem cells to by alginate (a jelly-ish goo) and collagen (rope-like proteins) that provided an adequate texture.
The end-result resembled contact lens, but provided an incredibly impactful aid in vision. Although artificial corneas still require donors, each individual cornea donation can be used to its full potential with this technology. The research team believes that with just a single, healthy cornea donation, they can harvest enough cells from it to create up to 50 artificial corneas – an amazing figure that could potentially change millions of live for the better.
