A Bioengineered Cornea Shows It Can Improve People’s Sight

August 11, 2022

(Wired) – As an alternative, researchers in Sweden have developed a bioengineered version made of collagen purified from pig skin that resembles the protein found in a human cornea. Bioengineered corneas could be made more readily available and may also have a longer shelf life than donor tissue. In a small trial, the implant restored or improved sight in 20 patients who were blind or visually impaired from a corneal condition called keratoconus. The results were published today in Nature Biotechnology. (Read More)
