Artificial cornea is a recently developed corneal bioengineering, which is more unique. Artificial cornea is made of allogeneic cornea through a special process, removing all kinds of antigenic substances in the cornea, so that it is not repulsive and can retain all kinds of collagen in the cornea, which is applicable to all kinds of corneal inflammation, corneal ulcer, and is especially suitable for corneal lamellar transplantation. Because normal human corneas need to be donated, and donor corneal material is not easy to obtain and in relatively small quantities, artificial corneas are of great importance. The price of an artificial cornea is around$10,000 and the cost of surgery is probably a few thousand dollars, so the cost of surgery plus materials for an artificial cornea transplant is$14,000-15,000.
