Repairing corneas
Vision depends on a healthy cornea, which is the film covering the ice surface and helps you focus. Over 40,000 people last year had transplanted cornea is. 10 million people go blind because of this problem.
A new biologically artificial cornea will soon induce healing by using the natural substances in a real cornea. The cornea is made of tissue called collagen. Human collagen is grown in yeast and mold it into a contact lens the shape of the cornea. Then a silver collagen is placed in the eye to coax the natural corneal cells to regrow and restore vision with an artificial cornea. It repairs the cornea from within. Linkoping Univ, Sweden 8.26.10
