- 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.
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 2.5 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.
