Researchers at Stanford University may have just gotten us one step closer to creating a cyborg. They've developed a new kind of artificial cornea, one that's "showing promise" in animal studies and could eliminate the need for cornea transplants completely. The cornea is made of two interwoven polymer gels — similar to the kind of squishy material that's in soft contact lenses. One layer provides durability while the other absorbs water, an important quality since cells in the eye need nutrients with high water content.
An estimated 10 million people worldwide have lost their sight to corneal disease. If the Stanford corneas are successful in human trials, some of them may get a second chance at sight. Being able to say you're part machine is a bonus.
