| 摘要 | In a contact lens for corrected-cornea crosslinking 10, a relief region 20 constituted by a concave portion and a pressing region 18 constituted by a convex portion are formed on a side of the lens in contact with a cornea 12 of a patient. When these regions are pressed to the cornea 12 to change a shape thereof, and a curvature of the concave curved-surface to be formed on the cornea 12 is defined as Ro and a curvature of the convex curved-surface of the pressing region 18 is defined as R s , R s is set, for example for correcting myopia, to satisfy R s = R 0 + 5.0D to R 0 + 10.0D. When the contact lens 10 having such a configuration is used for correcting the cornea and fixing the corrected state by crosslinking, the shape of the cornea can be accurately formed. | ||||||
