A method of producing an acellular cornea includes steps of subjecting a cornea of an animal to a decellularization process, and has not the step of treating the cornea with a protease, a chelating agent, a detergent, a glycerol, or a combination thereof. When a native cornea is processed by the method, the native structure and conformation of the native cornea are preserved while immunogenic matters are reduced to a level that the thus produced cornea may serve as a three-dimensional scaffold for host cells to grow thereon after transplantation.
