Claim Text:
1. An intraocular lens (IOL) comprising: at least one optical element comprising a first chiral optical surface and a second chiral optical surface; wherein the at least one optical element is adapted to provide chiral modulation of a light beam passing through the at least one optical element; wherein the optical surfaces are adapted to provide at least one adjustable focus; wherein the combination of the chiral optical surfaces is adapted such that a focal distance of the adjustable focus depends on a mutual position of the chiral optical surfaces; wherein each optical surface is a nearly continuous free-form refractive surface with a number of transition zones not exceeding one; and wherein at least one of the chiral optical surfaces comprises a parabolic screw-type chiral surface.
