Abstract

The invention relates to an intraocular negative spherical aberration lens and to a method for determining the refractive power of intraocular lenses. In an immersion medium environment, an intraocular lens refracts an incident wave provided with a curved oblong elliptic wavefront into an outbound wave whose wavefront is essentially spherical.

Claims (8)

1. An intraocular lens characterised in that in the environment of immersion medium it refracts an incoming wave with an elliptically oblongly curved wave front into an outgoing wave with a substantially spherical wave front.
2. An intraocular lens according to claim 1 characterised by a positive refractive power in the environment of immersion medium and a negative spherical aberration.
3. An intraocular lens according to claim 2 characterised by a refractive power at the centre of the lens which in the environment of immersion medium is greater than or equal to +3 dpt, wherein the lens is so designed that in the environment of air it refracts an incoming wave with a substantially plane wave front into an outgoing wave with a hyperbolic wave front.
4. An intraocular lens according to claim 3 characterised in that the hyperbolic wave front has an asphericity of less than or equal to -5.
5. An intraocular lens according to one of claims 3 and 4 characterised in that the intraocular lens has at least one convexly curved surface whose curvature has an asphericity of less than or equal to -1.
6. An intraocular lens according to claim 1 characterised by a refractive power at the centre of the lens which in the environment of immersion medium is at most +2 dpt and at least -1 dpt, wherein the lens is so designed that an incoming wave with a substantially plane wave front is refracted into an outgoing wave whose apex surface has a meridian with an inflexion point.
7. An intraocular lens according to claim 1 characterised by a refractive power at the centre of the lens which in the environment of immersion medium is less than or equal to -2 dpt, wherein the lens is so designed that an incoming wave with a substantially plane wave front is refracted into an outgoing wave with an elliptically oblongly curved wave front whose asphericity measured in air is greater than +10.
8. A method of determining the imaging properties of an intraocular lens comprising the steps:
- producing a parallel light beam, - orienting the light beam on to the intraocular lens, - breaking the light beam refracted by the intraocular lens down into a plurality of focused beams by means of a lens arrangement, and - detecting the local distribution of the beams focussed by means of the lens arrangement.
