An intraocular lens having a lens comprising: - a main lens part having a main lens surface and a main optical axis defining radial, tangential and axial directions; and - a recessed part (6, 7) having a recess surface (6', 7') and extending between said main optical axis and a circumference of said lens, said recessed part (6, 7) 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, 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 and said main lens surface defining: - an imaginary main lens surface section (4") that would have been part of said main lens surface in case said recessed part (6, 7) would have been absent, said recess surface (6', 7') being recessed with respect to said imaginary main lens surface section (4"), characterized in that 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 (6, 7) would have been absent, said imaginary main lens outer circumference section and said imaginary main lens surface (4") 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 (4") 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; and/or said imaginary main lens outer circumference section and said imaginary main lens surface (4") essentially being defined by line symmetry with respect to said main optical axis, said imaginary main lens outer circumference section and said imaginary main lens surface (4") on one side of said main optical axis 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 main optical axis, wherein said recessed part (6, 7) extends in an outward radial direction to an outer recess boundary remote from said main optical axis, said outer recess boundary extending along or beyond said imaginary main lens outer circumference section as seen in an outward radial direction. - a main lens part having a main lens surface and a main optical axis defining radial, tangential and axial directions; and - a recessed part (6, 7) having a recess surface (6', 7') and extending between said main optical axis and a circumference of said lens, said recessed part (6, 7) 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, 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 and said main lens surface defining: - an imaginary main lens surface section (4") that would have been part of said main lens surface in case said recessed part (6, 7) would have been absent, said recess surface (6', 7') being recessed with respect to said imaginary main lens surface section (4"), characterized in that 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 (6, 7) would have been absent, said imaginary main lens outer circumference section and said imaginary main lens surface (4") 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 (4") 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; and/or said imaginary main lens outer circumference section and said imaginary main lens surface (4") essentially being defined by line symmetry with respect to said main optical axis, said imaginary main lens outer circumference section and said imaginary main lens surface (4") on one side of said main optical axis 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 main optical axis, wherein said recessed part (6, 7) extends in an outward radial direction to an outer recess boundary remote from said main optical axis, said outer recess boundary extending along or beyond said imaginary main lens outer circumference section as seen in an outward radial direction.
