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.
