Abstract
This invention relates to a contact lens made of donor corneal tissue, to a method of preparing that lens, and to a technique of placing the lens on the eye. The lens is made of donor corneal tissue that is acellularized by removing native epithelium and keratocytes. These cells are replaced with human epithelium and keratocytes to form a lens that has a structural anatomy similar to human cornea. The ocular lens is used to correct conditions such as astigmatism, myopia, aphakia, and presbyopia.
