Abstract:
An artificial cornea and an associated manufacturing method are disclosed. The artificial cornea has two sides, each of which has an associated microstructure. In an embodiment, microlines can be provided on an anterior side, and a posterior side can have micropores. Both the geometry of the microstructures and their dimensions can be customized for an individual patient. The geometry of the artificial cornea itself and its dimensions can also be customized as such. In addition, the lifetime of the artificial cornea can be significantly enhanced by adding co-polymer(s) into the hydrogel to strengthen its mechanical properties. Patient recovery can be aided by adding peptides into the artificial cornea surfaces to improve cell growth post-operation.
