Abstract:
An intraocular lens with a lens comprises a main lens part having a main lens surface and a main optical axis defining radial, tangential and axial directions; and a recessed part having a recess surface and extending between said main optical axis and a circumference of said lens, the 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 main lens surface extends in an outward radial direction towards a main lens outer circumference section remote from said the optical axis. The main lens outer circumference section and the main lens surface define an imaginary main lens outer circumference section that would have at least partially provided a main lens outer circumference together with the main lens outer circumference section in case the recessed part would have been absent; and an imaginary main lens surface section that would have been part of the main lens surface in case said recessed part would have been absent, the recess surface being recessed with respect to the imaginary main lens surface section. The recessed part extends in an outward radial direction to an outer recess boundary remote from said main optical axis, the outer recess boundary extending along or beyond said imaginary main lens outer circumference section as seen in an outward radial direction.
