Researchers out of Linköping University have “developed an implant made of collagen protein from pig’s skin, which resembles the human cornea.” The implant was able to restore the vision of 20 people with “diseased corneas, most of whom were blind prior to receiving the implant.” This advancement is important because traditionally, someone suffering from corneal blindness or low vision would have to wait for a donated human cornea, of which there is a scarcity. The bioengineered cornea would open up another more accessible option for patients suffering.
