Scientists from Linköping University have created a collagen cornea implant that has already shown its effectiveness.
Swedish scientists developed a corneal implant made from porcine-derived collagen that restored sight in 20 volunteers in a trial. New Atlas reported this.
Every year, more than a million people worldwide become blind due to damaged or diseased corneas. They can only restore their sight by receiving a corneal transplant from a human donor. However, the shortage of corneal donors means that only one in 70 people with corneal blindness will receive a transplant. In addition, the surgical procedure can be expensive.
So scientists at Linköping University set out a few years ago to create a collagen cornea implant that could be stored for almost two years, compared to a donor human cornea that had to be used within two weeks.
Also, according to Neil Lagili, another important breakthrough is that instead of surgically removing the patient’s existing cornea, as is done with a donor cornea transplant, the new method allows you to make a small to make an incision in the eye shell and place the implant in the existing damaged cornea.
After two years of follow-up, experts reported that all 20 volunteers had their vision completely restored and did not experience any side effects from the surgery.
Earlier it was reported that in Lviv, local doctors, together with the Da Vinci robot, returned a whole life of a woman who could not eat and drink normally.
