Claim:
1. An intraocular lens having a lens comprising: the lens comprising a main lens part having a main lens surface and a main optical axis defining radial, tangential and axial directions, the main lens part being configured for optimizing distance vision of a person provided with the intraocular lens; and a recessed part having a recess surface and extending between said main optical axis and a circumference of said lens, said recessed part comprising a secondary lens part with a secondary lens surface having a positive relative optical power with respect to an optical power of said main lens surface, the secondary lens part being configured for optimizing near vision and/or intermediate vision of the person provided with the intraocular lens, said main lens surface extending in an outward radial direction towards a main lens outer circumference section remote from said main optical axis, said main lens outer circumference section coinciding with said circumference of said lens, said main lens outer circumference section and said main lens surface defining: said main lens outer circumference section and said main lens surface further define an imaginary main lens outer circumference section that would have at least partially provided a main lens outer circumference together with said main lens outer circumference section in case said recessed part would have been absent, said imaginary main lens outer circumference section and said imaginary main lens surface essentially being defined by mirror symmetry with respect to a mirror plane comprising said main optical axis, said imaginary main lens outer circumference section and said imaginary main lens surface on one side of said mirror plane essentially coinciding with mirror images of part of said main lens outer circumference section and part of said main lens surface, respectively, on the other side of said mirror plane, wherein said recessed part extends in an outward radial direction to an outer recess boundary remote from said main optical axis, said outer recess boundary at least essentially coinciding with said imaginary main lens outer circumference section, and wherein said recess surface essentially only comprises an essentially concave surface section extending along said outer recess boundary and said secondary lens surface extending to said essentially concave surface section.
