Abstract
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.
Claims3
An intraocular lens configured such that, in an in vivo environment of a human eye, an incoming wave with an elliptically oblately curved wave front is refracted into an outgoing wave with a substantially spherical wave front, wherein refractive power in a center of the lens in the in vivo environment of the human eye is greater than or equal to +3 dpt,
- the intraocular lens comprises at least one convexly curved surface having a curvature with an asphericity of less than −2.0, and is so designed that in an air environment, an incoming wave with a substantially plane wave front is refracted into an outgoing wave with a hyperbolic wave front.
