This invention provides a photocurable hydrogel, its preparation method, and its applications. The photocurable hydrogel comprises 45-55 parts of gel complex 1, 45-55 parts of gel complex 2, 0.01-0.5 parts of
photoinitiator, and 1-10 parts of natural
plant extract. The hydrogel of this invention exhibits good
biocompatibility and biodegradability. The photocuring process is convenient, and it can significantly reduce the
inflammation level in
tissue repair after pterygium excision, improve the
repair rate, shorten
treatment time, avoid
secondary surgery, reduce patient suffering and medical risks, and has a simple and low-cost preparation process, facilitating industrial production and large-scale application.
