The present invention relates to a system for corneal cross-linking of injured corneas, treating keratoconus, or correcting vision, the system comprising: a hyaluronic acid-dye conjugate; and a contact lens including an LED light source. In the present invention, a dye is activated by receiving light irradiated from the LED light source of the contact lens so as to generate radicals, thereby generating a covalent bond between amino acid radicals of corneal collagen, and strengthening a collagen layer. In the present invention, the hyaluronic acid-dye conjugate, in which hyaluronic acid is bound to the dye, is used to improve penetration of the dye in the cornea, and the contact lens is used together with the hyaluronic acid-dye conjugate to further improve the penetration of the dye. In addition, the structure of the lens which presses the center of the cornea deforms the shape of the cornea, thereby having a vision correction effect. |
