摘要:
This contact lens 30 for corrective corneal crosslinking has a lens part 30A and a reservoir part 12. The lens part 30A is configured of a UV-transmitting material and is provided with a pressing region 32 made to protrude in a convexly curved shape at a position that presses the center of the corneal dome and a relief region 34 comprising an annular concave part having a concave circular arc shape that surrounds the outer circumference of the pressing region 32, the lens part 30A correcting, on the side in contact with the cornea 2 in the eyeball 1 of a patient, at least the unaided visual acuity by the above pushing on the cornea 2 and changing the shape of the cornea 2. Furthermore, a reservoir part 12 for storing riboflavin solution, the reservoir part 12 being provided continuously and integrally on the outer side in the direction of lens thickness of the pressing region, communicating holes 44 for allowing the inside of the reservoir part 12 and the pressing region 32 to communicate, and a working electrode 14 having the same polarity as the riboflavin solution inside the reservoir part 12 are provided, the lens thickness is set at 0.3-1.0 mm in the lens center 30C, and the riboflavin solution permeates the corneal tissues by iontophoresis and permits UV exposure while the lens is mounted on the eyeball 1.
