The invention concerns an intraocular lens for the correction of astigmatic ametropia, which has both a torically refractive front face and a torically refractive rear face. The intraocular lens also has a torically refractive lens surface whose section curve in at least one principal meridian is described by an asphere. Finally the intraocular lens has a torically refractive lens surface with two principal meridians which include an intermediate angle that is not equal to 90&#xb0;.

Astigmatic intraocular lens

The invention concerns an intraocular lens with negative spherical aberration and a method of determining the refractive power of intraocular lenses. In the environment of immersion medium the intraocular lens refracts an incoming wave with an elliptically oblongly curved wave front into an outgoing wave with a substantially spherical wave front.
