An implant (1) for determining intraocular pressure, having at least one electrical pressure sensor (6) for measuring the intraocular pressure, at least one microchip (7) connected to the pressure sensor (6), and at least one antenna (8) connected to the microchip (7), wherein the microchip (7) generates digitally encoded data from the electrical signals of the pressure sensor (6), which data can be transferred via the antenna (8), by means of electromagnetic waves, to a receiver located outside the eye, and said components are accommodated in a small housing (11) whose external dimensions (12, 13, 14) are limited in such a way that it is possible to place the implant (1) between the sclera (3) and the choroid (4) of the eye (2), said implant (1) being improved, according to the invention, by virtue of the fact that the pressure sensor (6) is accommodated on an outer face (16) of the housing of the implant (1), which outer face (16), in the eye (2), is placed in contact with the choroid (4).
