摘要:
CONTACT LENS FOR CORRECTIVE CORNEAL CROSSLINKING AND METHOD FOR PRODUCING SAME A contact lens for corrective corneal crosslinking 30 has a lens part 30A and a reservoir part 12. The lens part 30A is constituted 5 of a UV transmitting material, and provided, on a side thereof being in contact with the cornea 2 of an eyeball 1 of a patient, with a pressing region 32 configured to project in a convexly curved shape at a position for pressing the corneal dome center, and a relief region 34 including an annular concave part of a concavely 10 circular arc shape that surrounds the outer circumference of the pressing region 32. These regions are pressed to the cornea 2 to change the shape of the cornea 2 for correcting at least the naked eye vision. The contact lens is further provided with the reservoir part 12 that is disposed seamlessly and integrally therewith on 15 an outer side of the lens in a thickness direction in the pressing region 32, a communication hole 44 for communication between the inside of the reservoir part 12 and the pressing region 32, and a working electrode 14 that has the same polarity as that of the riboflavin solution in the reservoir part 12. The lens part has 20 a lens thickness of 0.3 mm or greater and 1.0 mm or smaller at a lens center 30C. The riboflavin solution can be infiltrated into a corneal tissue by iontophoresis and UV irradiation is possible while the contact lens is mounted on the eyeball 1. [FIG. 1] 25
