摘要:
A contact lens (100, 200, 300, 400) for treating an eye with myopia, the contact lens having an optical zone (110) comprising a surface having a first power, which corrects the distance vision of the eye, and comprising a structural profile to perform the remodeling of the cornea by flattening the eye when the contact lens fits the eye; wherein the optical zone (110) comprises an internal optical zone (220, 320, 420) and an external optical zone (210, 310, 410) surrounding the internal optical zone, wherein said outer optical zone comprises a first outer subzone (340 , 410a) surrounding the inner optical zone and a second outer subzone (350, 410b) surrounding the first outer subzone, where the inner optical zone (220, 320, 420) is thicker than the first outer subzone ( 340, 410a), providing the greatest thickness of said structural profile to perform the corneal remodeling and where the second outer subzone (350, 410b) has a greater thickness with respect to the first outer subzone (340, 410a), providing another part of said structural profile for remodeling the cornea, said internal optical zone having a differential power, which is possible with respect to the first power, and where the differential power is between 0.50 and 4.00 or between 1 , 00 and 4.00 or between 1.50 and 4.00, where said second outer subzone (350, 410b) is separated from the internal optical zone (220, 320, 420) by a surface having the first power, where the second outer subzone (350, 410b) has a differential power, which is possible with respect to the first power, where said second outer subzone (350, 410b) is surrounded on its outer peripheral side by a second surface having the first power.Una lente de contacto (100, 200, 300, 400) para tratar un ojo con miopía, teniendo la lente de contacto una zona óptica (110) que comprende un superficie que tiene una primera potencia, que corrige la visión a distancia del ojo, y que comprende un perfil estructural para realizar la remodelación de la c
