Claim 16:
17. An intraocular pressure measuring device (1) comprising:
a contact lens (10) presenting an inner surface (101) and an outer surface (102), and
a pressure sensor (2) united with said contact lens (10) and located such that the pressure sensor is applied to sense the pressure of an eye (8) of a user through a pressure transmitting filler material for sensing the intraocular pressure (IOP) of said eye (8) when said contact lens (10) is worn by said user,
characterized in that said contact lens (10) comprises a first portion (11) and a second portion (12), said second portion (12) being adapted to at least partially rigidify a central portion of the inner surface (101) of said contact lens (10) so as to maintain said rigidified inner surface (101) with a curvature radius adapted to flatten at least a portion of the eye surface in indirect contact with the pressure sensor (2) so as to reach a pressure equilibrium around the pressure sensor (2) when said contact lens (10) is worn by said user
said pressure sensor (2) is in indirect contact with the eye of the user when said user is wearing said contact lens (10) and said pressure sensor (2) is located within a cavity (121) formed in an inner concave side of said second portion (12), and wherein said cavity (121) is filled with the pressure transmitting filler material (122) that covers said pressure sensor (2) such that a layer of said filler material (122) is located between said pressure sensor (2) and the inner surface of the contact lens (10).
