A team of scientists at the Linköping University in Sweden have developed a way to help people with damaged corneas and even restored the eyesight of 19 during a recent clinical trial, GizmodoThe scientists restored people’s eyesight using bioengineered implants created from pig skin — including several deemed legally blind.

However, significant damage and some diseases can lead to permanent damage, requiring a corneal graft, or a transplant, to restore vision.However, bioengineered implants from pig skin could provide a mass-produced alternative to corneal grafts.
Significant eyesight improvements were observed in 19 of the 20 patients, of which 14 were previously considered legally blind.“The results show that it is possible to develop a biomaterial that meets all the criteria for being used as human implants, which can be mass-produced and stored up to two years and thereby reach even more people with vision problems,” study author Mehrdad Rafat said in a
