The amnion is divided into five layers: epithelial cell layer, basement membrane, parenchymal layer, fibroblast layer, and sponge layer. The amnion has the functions of promoting epithelial repair, inhibiting scar formation, inhibiting cornea neovascularization, inhibiting immunoreaction and the like, so that the amnion covering operation and the amnion transplantation operation are widely applied to treating ocular surface diseases and obtain good clinical curative effect. However, the means for fixing the amnion in the amnion covering operation which is clinically applied at present is mainly surgical suture, which inevitably traumatizes the ocular surface, and because the amnion is thin and is easy to break and perforate, multiple operations are often needed to achieve the treatment purpose.
