Multifocal Iol
First Claim
1. Intraocular lens (IOL) comprising a lens part with a centre, which lens part is provided on the periphery with two supporting parts (haptics), wherein one supporting part is made radially non-deformable and wherein another supporting part is made radially elastically deformable, such that when a radial compression force is applied to the IOL the centre of the lens part moves, the lens part being provided with two optical fields with different optical properties located near the centre.

Abstract
Intraocular lens consisting of a centrally located lens part with supporting parts (haptics) on either side. According to the invention one supporting part is non-deformable and another supporting part, located approximately opposite said supporting part, is deformable. In this way it is achieved that when the ciliary cell contracts the reduction in the space therein is used for moving the centre of the lens part. By arranging the transition between distance and near part in a multifocal lens on said centre, switching from the distance part to the near part can be obtained for the user in an almost natural way.

2. Intraocular lens, wherein the supporting part located at the top in use is made radially elastically deformable and the part located at the bottom is made radially non-deformable.
- 13. Intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a lens part with a centre, which lens part is provided on the periphery with two supporting parts (haptics), characterised in that the supporting parts are made mutually differently radially deformable under the influence of a radial compression force, with a mutual difference such that when a radial compression force is applied to the IOL the centre of the lens part moves, the lens part being provided with two optical fields with different optical properties located near the centre.
- 14. Intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a first lens part with a centre, which first lens part is provided on the periphery with two supporting parts (haptics), wherein the IOL comprises a second lens part axially behind the first lens part, interconnected by means of the supporting parts, which supporting parts are made mutually differently radially deformable under the influence of a radial compression force, with a mutual difference such that when a radial compression force is applied to the IOL, the centre of the first and second lens parts move mutually radially.
- 15. Intraocular lens (IOL) for implantation in a posterior chamber of the eye, wherein the IOL has a diameter of approximately 11-13 mm and comprises a first lens part with a centre, which first lens part is provided on the periphery with two supporting parts (haptics), wherein the IOL comprises a second lens part axially behind the first lens part, and wherein the second lens part is connected to the first lens part via supporting parts that are connected to the supporting parts, wherein one supporting part is non-deformable in the radial direction and an additional supporting part is radially deformable such that when a radial compression force is applied to the IOL, the centre of the first and second lens parts move mutually radially.
