Rebound Technology


Icare rebound tonometer was developed to find a new, easy and patient-friendly method of measuring intraocular pressure. It is a major breakthrough obtained after a decade of development work by a Finnish MD, Mr. Antti Kontiola. The realization of the rebound method has involved a number of clinical test partners, including the Helsinki University Eye Clinic (Finland) in the human application, and the Mount Sinai Medical School (US) in the animal application.

The rebound technology is based on the rebound measuring principle, in which a very light-weight probe is used to make a momentary contact with the cornea. In the rebound technology, motion parameters of the probe are recorded during the measurement. An induction based coil system is used for measuring the motion parameters. An advanced algorithm combined with the state of the art software analyzes deceleration and the contact time of the probe while it touches the cornea. Deceleration and the contact time 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.

How iCare Works?

Based on a proven accurate measuring principle, in which a very light probe is used to make momentary and gentle contact with the cornea. The measurement is barely noticed by the patient and often does not even cause corneal reflex.
