The invention relates to an intracorneal diffractive lens having phase inversion, said intracorneal diffractive lens including: a core (2) having a first surface and a second surface opposite the first surface； at least one first hydrogel layer (5) extending over the first surface of the core； and a second hydrogel layer (6) extending over the second surface of the core. The first hydrogel layer (5) includes, on the surface thereof turned toward the core, a plurality of concentrically or coaxially projecting annular areas (7), each annular area (7) having a continuously varying thickness toward the periphery of the lens. The first and second layers (5, 6) have a nutrient and oxygen permeability substantially identical to that of the corneal tissue, and at least one of the annular areas (7) of the first layer (5) is in contact with the second hydrogel layer (6).
