Frequently asked questions

  • What do the eye pressure values mean for me? When should I be concerned about the eye pressure readings?

    Intraocular pressure (IOP) is the fluid pressure in the eye and is also known as eye pressure. IOP is only one aspect of eye health and glaucoma. IOP values alone cannot be used to diagnose accurately or monitor glaucoma.. Saying this, IOP reduction is still the only proven method for slowing glaucomatous progression.

    Having an accurate overview of your diurnal IOP profile may assist your eye care professional in tailoring a management program to suit your individual needs. You should always discuss any IOP concerns with your eye care professional, to ascertain what normal looks like for you. Every glaucoma patient is different.


  • How do I show my results to my eye care professional (ECP)?

    You can show your results in several ways:

    • Directly on the iCare PATIENT2 app on your phone
    • Print out or email a report from the computer
    • You can ask your ophthalmologist to subscribe for the iCare CLINIC software so that they can view your measurement results online
  • Does it hurt?

    Measurement is painless. The light-weight probe touches the cornea momentarily and some patients don’t even notice the measurement.

  • How often should I calibrate the tonometer?

    The tonometer does not require any routine servicing or calibration. If there is a reason to believe that the servicing of the tonometer is necessary, contact the local distributor or the manufacturer.

  • How often should I change the probe?

    The probes are for single use (single pair of measurement sequences) only. Each probe can be used once to take a successful measurement in both eyes. If you eye is inflamed or infected, measure the healthy eye first.


  • How often should I change the probe base?

    Every 6 months is recommended to maintain the accuracy of the device.

  • Where can I find all the iCare self-tonometer instruction manuals and materials?

    You can find all the manuals and materials on the iCare USB drive, located inside the iCare carrying case. You can also download digital versions from our website.

  • How do I clean my tonometer?

    You can clean the plastic surfaces with a cloth or a paper towel dampened with water.

  • Can I travel with the tonometer?

    Yes, you can take the tonometer anywhere with you.
