Claims2
An intraocular lens set comprising:
- first and second intraocular lenses, each having a front side, a rear side, a far vision focus, a near vision focus, a refractive power and a diffractive power, and
- a diffractive structure, providing the diffractive power, disposed on the rear side of each of the lenses,
- a profile height of the diffractive structure consisting of a profile height corresponding to a wavelength in the green spectral region of visible light,
- the diffractive and the refractive powers being added such that the far vision focus of the first intraocular lens has a higher contribution to a total light distribution passing through the first lens than the second lens and the near vision focus of the second intraocular lens has a higher contribution to the total light distribution passing through the second lens than the first lens.
