IC100 Rebound Tonometer

For practices that want fast, drop-free tonometry in a compact handheld device, the iCare IC100 delivers accurate IOP measurement with zero patient prep — no anesthetic drops, no air puff, no calibration. Its patented rebound technology produces reliable results from a light probe touch that most patients barely feel, making it ideal for pediatric, anxious, or high-volume patient populations. If you’re looking to replace Goldmann applanation or air-puff tonometry with something faster and more comfortable for patients and staff alike, the IC100 is the most widely adopted rebound tonometer in optometry.

Practice Fit

Where The IC100 Wins

The IC100 is strongest when a practice needs painless IOP checks that are easy to delegate, easy to repeat, and easy for patients to accept.

Best Fit

Routine glaucoma screening, comprehensive exams, pediatrics, and any lane where staff need a fast handheld IOP option without adding drops or an air puff.

Why This

If your current IOP workflow involves Goldmann applanation or air-puff tonometry, the IC100 eliminates anesthetic drops, patient anxiety, and daily calibration while delivering rebound accuracy that correlates well with Goldmann in clinical studies. For practices measuring dozens of pressures per day, the time and patient-comfort savings add up fast.

Practice Impact

It speeds pretesting, improves patient acceptance, and makes it easier to capture pressure on patients who dislike contact tonometry or struggle with traditional screening flow.

Design Advantage

Built for the Way You Work

Pocket-Sized

At just 140g without batteries, the IC100 fits in a coat pocket and moves between lanes, exam rooms, and screening stations without slowing anyone down.

Zero Prep

No calibration, no anesthetic drops, no air puff. Power on and measure — the IC100 is ready when you are, with no consumables beyond single-use probe tips.

Any Patient

Pediatric, anxious, post-surgical, or non-compliant — the gentle rebound probe touch works for patients who refuse or cannot tolerate contact or air-puff tonometry.

In Practice

IC100 in Clinical Use

The IC100’s compact form factor and one-hand operation make it the go-to tonometer for fast, accurate IOP measurement across every patient type.
