How big is the implant?
The thickness of the implant is less than half a millimeter. The diameter depends on the patient’s eye the maximum size is 12 millimeters.
Where exactly is the implant placed?
The implant is placed behind the iris. It cannot be seen or felt there.
What does the implant consist of?
It consists of proven biocompatible material, in particular the microsensor and a gold structure that functions as antenna. The tiny sensor system is embedded in high-quality and strictly controlled silicone which is been used in medical implants for a long time.
Does the pressure sensor come into contact with the tissue of the eye?
The pressure sensor is embedded in highly compatible silicone, being the only part having contact to the surrounding tissue.
Does the implant cause pain?
No. The implant is usually not being perceived in the eye, just as an artificial lens.
Can you see the implant?
If the pupil is dilated to a maximum (e.g. after eye drops at the ophthalmologist), you may be able to see a small part of the implant. In everyday life, however, it is not visible, but disappears completely behind the iris.
Does the implant obstruct vision?
No, the sensor ring sits completely behind the iris, leaving the so-called "optical axis" (through pupil and lens) completely free.
Does the implant contain a battery?
There is no battery in the implant that needs to be charged or replaced. The implant is only active for the measurement once the reader is held in front of the eye and the measurement process is started.
How does the implant receive its current?
During measurement, the reader generates a very weak current flow in the sensor coil which - shielded by the plastic sleeve - enables the measurement and transmits the data to the reader.
How long does the implant last?
The implant has a life-long, maintenance-free durability. It is designed to remain in the eye permanently.
Can the implant also be removed?
If really necessary, the implant can be removed at any time with an uncomplicated outpatient procedure.
