- Combination of auto refractometer, auto keratometer, non contact tonometer and non contact pachymeter
- High measurement accuracy
- Clinically important functions ‐ accommodation measurement and opacity assessment
- User-friendly design
- Space saving design that is a comfortable and efficient upgrade to your practice

Automated calculation of corrected IOP

The TONOREF™ III provides the automated calculation function of the corrected IOP based on the central corneal thickness.

Accommodation measurement

Objective measurement of accommodation is performed with patient's focusing on a target which moves from distant to near.

Opacity assessment

The retroillumination image allows evaluation of media opacity.

Large pupil zone imaging method

The large pupil zone imaging method measures the central refraction and a large area refraction.
The difference of the measurement allows assessment of the effect of pupil size such as a vision in dim light.

Quick ref measurement mode

The quick ref measurement mode* provides faster and simpler measurement for patients who have difficulty in alignment. By relaxing the measurement range, children or patients whose eye movement is not stable can still be measured smoothly.
*Please note that during the quick ref measurement mode, the results are more likely to fluctuate compared to the normal AR measurement mode.

Double mire ring method

Keratometry measurements performed with the mire ring method reduce interference from the eyelids.
The TONOREF™ III performs measurements at diameters of 3.3 mm and 2.4 mm.
Comparison of the two values allows a better understanding of the cornea shape.

Patient-friendly air puff

Automatic Puff Control (APC)
In subsequent measurements, the APC function performs the measurement with the minimum air pressure based on the previous measurement data.

Softer and quieter air puff
Gentle nozzle design
A gentle nozzle design reduces patient’s perception of physical pressure.
