iCare’s unique rebound technology has made the iCare tonometer one of the most popular choices among eye care professionals and patients worldwide. The reliability and reproducibility of the measurements have been proven in over 200 clinical studies, establishing iCare’s position as the market leader in handheld tonometry.
iCare’s first patented rebound tonometer revolutionized the world of tonometry in 2003. Today, iCare tonometers are available in over 100 countries and more than 100 000 devices have been sold globally.
Distinguished reliability in IOP measurement proven in over 200 clinical studies
iCare’s handheld rebound tonometers have been heavily researched by the scientific community. According to several recent studies*, iCare’s rebound tonometry offers excellent reliability and demonstrates the capability to portray changes in intraocular pressure (IOP) more robustly than Goldmann applanation tonometry.
Combined with an enhanced user experience for eye care professionals and patients alike, this presents a noteworthy challenge to the gold standard of IOP measurement.
Innovative rebound technology enables safe, hygienic, and patient-friendly IOP measurement
iCare’s rebound technology is based on a simple, effective principle: the lightweight, single-use probe makes quick contact with the cornea and rebounds back. This applanation-free method allows painless and hygienic IOP measurement without the need for topical anesthetic or calibration. The safe and gentle measurement technique also enables measuring during and immediately after surgery.
200 degrees of positional freedom with the iCare IC200 tonometer
Usability and performance have always been at the heart of iCare’s tonometers, and recent developments have taken these aspects even further. The iCare IC200 tonometer offers a full 200 degrees of positional freedom, making it possible to measure IOP accurately in supine, reclined, and sitting positions. This is especially useful in clinical, surgical, or emergency settings.
The alignment assistant makes it quick and easy to achieve accurate results. A high-visibility indicator confirms the correct position for reliable measurement with a green light.
20 years of experience in versatile clinical tonometers
During the past 20 years, iCare has launched an assortment of rebound tonometers for different uses, from the most versatile clinical tonometer with positional freedom to the world’s first self-tonometer for 24-hour IOP monitoring by patients themselves.
“The difference between readings we obtain in the office and the data from the iCare HOME is like the difference between a single snapshot and a continuous movie of a patient’s daily life.”
