These days, medical advances seem to be happening in the blink of an eye. Now, British scientists report they have created human corneas using 3D-printing technology.
The researchers said they hope this breakthrough will one day ensure an unlimited supply of corneas. Human corneas are now in short supply. Yet, there are 10 million people around the world who need them to prevent blind...
