iCare rebound tonometer was developed to find a new method of measuring intraocular pressure. It is a major breakthrough obtained after a decade of development work by Finnish MD Antti Kontiola. The realization of the rebound method and its equipment has involved a number of partners, including the Helsinki University Eye Clinic in the clinical testing, and the Mount SinaiMedical School in the US in developing the veterinary modification of the instrument.
Unique technology enables safe, painless and hygienic procedure
Rebound technology is based on a rebound measuring principle, in which a very light-weight probe is used to make momentary contact with the cornea. In rebound technology, the motion parameters of the probe are recorded during the measurement. Induction based coil system is used for measuring the motion of the probe. Advanced algorithm combined with state of the art software analyzes the probe deceleration, contact time and other parameters of the probe while it touches the cornea. The deceleration and other rebound parameters of the probe change as a function of IOP. In simple terms, the higher the IOP, the faster the probe decelerates and the shorter the contact time.
Anaesthesia is not needed since the touch of the probe is so gentle and the measurement is barely noticed by the patient.
