摘要:
A method of accurately fabricating a non-human donor corneal tissue for implantation into a recipient human cornea, the method comprising the steps of: removing corneal tissue from a donor with a femtosecond laser placing the corneal tissue in a fixative solution for a selected time interval to cross-link the collagen fibrils in the tissue and prevent swelling of the corneal tissue and shaping the tissue to provide a conical inlay of a selected shape and thickness having one or more radial extensions. The method is such that the corneal inlay may be attached to the peripheral corneal and/or the sclera. The method is such that the corneal inlay may be stored for a period of up to two years prior to attachment.
