Abstract

In order to make available an implant for implanting in an eye and/or on an eye, with fixing means arranged in a first plane and with a recess extending substantially in the first plane, which implant avoids the disadvantages of the prior art and can be better implanted, particularly as regards measurement of the intraocular pressure and reduced trauma to a patient, it is proposed that the implant, in a second plane at a distance from and substantially perpendicular to the first plane, has holding means for holding at least one sensor module having a sensor and/or at least one sensor module.

Claims

1. A method comprising:

implanting in and/or on an eye an implant with a fixing apparatus that is arranged in a first plane, having a recess extending substantially in the first plane, characterised in that the implant in a second plane at a distance from and substantially perpendicular to the first plane has a holding apparatus for holding at least one sensor module having a sensor and/or at least one sensor module.

2. The method of claim 1, characterised in that, in an implanted state of the implant, the holding apparatus and/or the sensor module is arranged in a region between a capsular bag and iris of the eye.

3. The method of claim 1, characterised in that the implant has at least one spacer element between the holding apparatus and the fixing apparatus.

4. The method of claim 3, characterised in that the spacer element has a portion which is arranged on an edge bounding a recess of a capsular bag.

5. The method of claim 4, characterised in that the portion is directed radially and outwardly in a direction of a radius of curvature locally defined on the edge.

6. The method of claim 1, characterised in that the fixing apparatus and the holding apparatus and/or the sensor module are mountable on one another in a mechanically reversible way.

7. The method of claim 1, characterised in that the fixing apparatus is formed as a capsular tension ring.

8. The method of claim 1, characterised in that the fixing apparatus has at least one support element, which is supported on a tissue structure in a direction transverse to an optical axis of the eye.

9. The method of claim 8, characterised in that the fixing apparatus has at least one deflecting element for deflecting the support element in a deflection plane wherein the deflection plane in the implanted state is positioned perpendicular to the optical axis of the eye.

10. The method of claim 9, characterised in that the at least one deflecting element is able to recover its shape after deformation of the at least one deflecting element, wherein the deflection is based on the shape recoverability.

11. The method of claim 10, characterised in that the shape recoverability is elastic.

12. The method of claim 10, characterised in that the shape recoverability is stimulated by a stimulus.

13. The method of claim 12, characterised in that the stimulus is a change in temperature.

14. The method of claim 9, characterised in that the at least one deflecting element and/or the support element comprises of a polymer, in particular a biocompatible polymer.

15. The method of claim 9, characterised in that the at least one deflecting element and/or the support element comprises at least in portions of a material having shape memory properties.

16. The method of claim 9, characterised in that the at least one deflecting element in the direction perpendicular to the deflection plane has a shape which is rigid with respect to dents.

17. A method comprising:

implanting in and/or on an eye an implant that is arranged in a first plane, having a recess extending substantially in the first plane;

holding at least one sensor module having a sensor and/or at least one sensor module in the implant in a second plane at a distance from and substantially perpendicular to the first plane; and

deflecting a support element in a deflection plane with at least one deflecting element, wherein the deflection plane is positioned in an implanted state perpendicular to an optical axis of the eye.

18. An implant comprising:

a fixing apparatus for implanting in and/or on an eye an implant;

a holding apparatus for holding at least one sensor module having a sensor in the implant; and

the sensor module, comprising the sensor,

wherein holding apparatus is spatially separated from the fixing apparatus along an optical axis of the eye.

19. The implant of claim 18, wherein the fixing apparatus has at least one support element, which is supported on a tissue structure in a direction transverse to the optical axis of the eye.

20. The implant of claim 19, wherein the fixing apparatus has at least one deflecting element for deflecting the support element in a deflection plane wherein the deflection plane in an implanted state is positioned perpendicular to the optical axis of the eye.
