Abstract

An injector (1) for implanting a sensor implant (2) in the human or animal eye, in particular for the suprachoroidal implantation of a pressure sensor for the wireless measurement of the intraocular pressure, is improved in terms of rapid, complication-free, low-trauma and low-wear suprachoroidal implantation in that, to accommodate the sensor implant, the injector (1) has a substantially tubular injection chamber (8), the inner wall surfaces (9, 10) of which have a non-rotationally symmetrical cross section, preferably an oval or rectangular cross section, in that, at a free end, the injection chamber (8) is provided with an injection opening (13), through which, during implantation, the sensor implant (2) can slide out and slide into a sclera incision in the eye, wherein the inner wall surfaces (9, 10) of the injection chamber (8) enclose the likewise non-rotationally symmetrical cross section of the sensor implant (8) and prevent a rotation of the sensor implant (2) about an axis of rotation extending in the direction of the injection (11).
