Unique technology enables safe, painless and hygienic IOP measurement

The rebound technology is based on the rebound measuring principle in which a light-weight probe is used to make a momentary contact with the cornea.  An induction based coil system is used for measuring motion parameters of the probe.  An advanced algorithm combined with state-of-the-art software analyzes deceleration and contact time of the probe when it touches the cornea. Deceleration and contact time of the probe change as a function of IOP.  For example, the higher the IOP the faster the probe decelerates and shorter the contact time.

The Icare® rebound tonometers do not require any maintenance, calibration or regular service.  It is recommended the user cleans the probe base every six months and replace the probe base yearly.  Probe base cleaning is simple and described in the user manual.
