The Icare story began originally with the development of the rebound tonometer. A major breakthrough was obtained after a decade of hard work by Finnish MD, Mr. Antti Kontiola.  Dr. Kontiola wanted to find a new, easy and patient-friendly method of measuring intraocular pressure.

The realization of rebound technology and its equipment has involved a number of partners; Helsinki University Eye Clinic in clinical testing and the development of the veterinary instrument with Mount Sinai Medical School in the United States.

Today the Icare® tonometer has obtained world wide official clearances (US FDA, CE, CFDA, etc.) with over 80,000 satisfied users in more than 50 countries. Several clinical studies show the data obtained by Icare® is comparable to the measurement results with the Goldmann Applanation Tonometer (GAT).

Icare USA is a subsidiary of Icare Finland, the original developer and global leader in handheld tonometry.  Icare Finland is a part of Revenio Group Corporation, a public company listed on the Helsinki Stock Exchange.
