Abstract:
A contact lens for corrective corneal crosslinking has a lens part and reservoir part. The lens part is constituted of a UV transmitting material, and provided, on a side thereof being in contact with the cornea of a patient's eyeball, with a pressing region configured to project in a convexly curved shape at a position for pressing the corneal dome center, and a relief region including an annular concave part whose cross section has a concavely circular arc shape that surrounds the pressing region's outer circumference. The reservoir part is disposed seamlessly and integrally therewith on the lens' outer side in a thickness direction in the pressing region, the reservoir part is provided with a communication hole for communication between the inside of the reservoir part and the pressing region, and a working electrode that has the same polarity as that of the riboflavin solution in the reservoir part.

Claim (Index 1):
A contact lens for corrective corneal crosslinking, the contact lens being constituted of a UV transmitting material, the contact lens having a relief region including a concave part and a pressing region including a convex part that are formed on a side of the contact lens in contact with a cornea of a patient, the contact lens being for correcting at least one of a naked eye vision and keratoconus cornea by pressing the relief region and the pressing region to the cornea to change a shape of the cornea, the contact lens for corrective corneal crosslinking comprising a lens part and a reservoir part, wherein:\n the lens part has, on the side thereof being in contact with the cornea of the patient, a circular central lens region that is located at a position being in contact with a corneal dome center when the contact lens is mounted on the cornea, and a ring-shaped region in a circular-ring shape surrounding the central lens region; one of the central lens region and the ring-shaped region constitutes the pressing region or the relief region and the other constitutes the relief region or the pressing region; the reservoir part is constituted of the same material as that of the lens part, is disposed and formed to project seamlessly and integrally with the lens part at an outside position in a lens thickness direction in the central lens region, is configured to store a riboflavin solution for corrective corneal crosslinking, and has a working electrode that is disposed at a position being in contact with the riboflavin solution and has the same polarity as that of the riboflavin solution; and the lens part has a communication hole for communication between an inside of the reservoir part and the central lens region, has a lens thickness of 0.3 mm or greater and 1.0 mm or smaller in the central lens region, and enables infiltration of the riboflavin solution into a corneal tissue by iontophoresis.
