  • Patent number: 11925686
    Abstract: The present invention relates to a medicinal material for light therapy, comprising a matrix material and a photosensitizer, wherein the photosensitizer is dispersed inside the matrix material by copolymerization, is mixed inside the matrix material, or attached to the surface of the matrix material by surface grafting, modification, coating and the like. The present material can kill diseased tissue cells with a radiation under selected wavelength so as to obtain a phototherapy treatment of ophthalmic diseases. The present invention also provides a process for preparing the material and a use in preparing an ophthalmic medical device.
