iCare tonometers are easy-to-use, hand-held, battery-operated devices that require only minimal training. All iCare tonometers use a patented rebound technology for quick and reliable intraocular pressure (IOP) measurements. The painless and pleasant measuring is accurate and efficient, enabling high patient flow when it comes to tests such as glaucoma screening. The ergonomic design and intuitive user interface ensure safe and accurate operation of the instrument. iCare tonometers also include a model for self-measurement of IOP by patients.
