23 Jul Method for manufacturing and storing corneal injury scar-free repairing device
Abstract
The invention relates to a method for manufacturing and storing a corneal injury scar-free repairing device. Specially-prepared amnion elements are settled or bonded in or on the surfaces of various biological or synthetic attaching devices such as the invisible contact lens through the novel carrier controlled release technology and the biological tissue engineering technology so as to form the corneal or conjunctiva injury scar-free repairing device. At the early stage of the corneal or conjunctiva injury, the affected corneal tissue or the affected conjunctiva tissue is covered with the amnion elements of the corneal or conjunctiva injury scar-free repairing device, the amnion elements, such as the necessary cell growth factors, the tissue repair factors and protease inhibitors, of the corneal or conjunctiva injury scar-free repairing device are diffused to the affected corneal tissue or the affected conjunctiva tissue due to the special superfine structure of an amnion basilar membrane and the stem cell characteristic of amniotic epithelial cells, and therefore growth of epithelial cells of the corneal or the conjunctiva is promoted, the affected corneal tissue or the affected conjunctiva tissue is stimulated, regulated and controlled to heal orderly, and less scars are formed on the affected corneal tissue or the affected conjunctiva tissue.
