Abstract

Intraocular pressure measuring and/or monitoring device comprising a soft contact lens and a pressure sensor united with the soft contact lens, the pressure sensor being located such that it is applied against an eye of a user for sensing the intraocular pressure (IOP) of the eye when the soft contact lens is worn by the user, wherein the soft contact lens is softer than a surface of the eye and is configured to adapt its shape to the shape of the eye under the effect of capillary force maintaining the contact lens on the eye when the user is wearing the contact lens.

Claims

1. An intraocular pressure measuring and/or monitoring device comprising a soft contact lens and a pressure sensor united with said soft contact lens, said pressure sensor being located such that it is applied against an eye of a user for sensing the intraocular pressure (10P) of said eye when said soft contact lens is worn by said user,

wherein said pressure sensor is located in a cavity formed in an inner concave side of said contact lens, and wherein said cavity is filled with a pressure transparent filler material that covers said pressure sensor such that a layer of said filler material is located between said pressure sensor and the surface of said eye when said user is wearing said contact lens.

12. The intraocular pressure measuring and/or monitoring device of claim 1, wherein said filler material is a silicone gel.

13. The intraocular pressure measuring and/or monitoring device of claim 1, wherein said filler material is softer than the material of said soft contact lens.

14. The intraocular pressure measuring and/or monitoring device of claim 1, wherein said filler material is of the same softness as the material of said soft contact lens.

15. The intraocular pressure measuring and/or monitoring device of claim 14, wherein said filler material is the same material as the material of said soft contact lens.

16. The intraocular pressure measuring and/or monitoring device of the claim 1, wherein said cavity is a circular groove around the centre of said contact lens.

17. The intraocular pressure measuring and/or monitoring device of claim 1, wherein said cavity is formed in the centre of said contact lens.

18. The intraocular pressure measuring and/or monitoring device of claim 1, wherein an external surface of said filler material is convex.

19. The intraocular pressure measuring and/or monitoring device of claim 1, wherein an external surface of said filler material is structured.

20. A kit comprising:

an intraocular pressure measuring and/or monitoring device according to claim 1;

a portable recording device configured for communicating with said intraocular pressure measuring and/or monitoring device and for storing data received from said intraocular pressure measuring and/or monitoring device.

21. The kit of claim 20 wherein said portable recording device is configured for powering said intraocular pressure measuring and/or monitoring device over a wireless inductive communication channel.

22. The kit of claim 20, comprising two intraocular pressure measuring and/or monitoring device according to claim 1, wherein said portable recording device is configured for communicating with said two intraocular pressure measuring and/or monitoring devices and for storing data received from said two intraocular pressure measuring and/or monitoring devices.

23. An intraocular pressure monitoring system comprising:

an intraocular pressure measuring and/or monitoring device according to claim 1;

a portable recording device configured for communicating with said pressure measuring and/or monitoring device and for storing data received from said intraocular pressure measuring and/or monitoring device;

a computing device configured for communicating with said portable recording device for receiving and/or processing and/or storing data received from said portable recording device.

24. The intraocular pressure monitoring system of claim 23, wherein said portable recording device is configured for powering said pressure measuring and/or monitoring device over a wireless inductive communication channel.

25. The intraocular pressure monitoring system of claim 23, comprising two intraocular pressure measuring and/or monitoring, devices according to claim 1, wherein said portable recording device is configured for communicating with said two intraocular pressure measuring and/or monitoring devices and for storing data received from said two intraocular pressure measuring and/or monitoring devices.
