Myopia, hyperopia and astigmatism are all ophthalmic diseases related to the refractive power of an eyeball system, and the condition of an illness can be relieved by changing the refractive power of a cornea, so that the effect of restoring vision is achieved.
An ultraviolet cross-linking operation method features that the photosensitizer coated on the surface of cornea is cross-linked with the collagen fibres of cornea under the irradiation of ultraviolet ray to increase the mechanical strength of cornea, resulting in the relief of the further deterioration of keratoconus and the decrease of eyeball system's power under myopia, hyperopia and astigmatism.
