NIDEK TONOREF III AUTOMATIC REFRACTOMETER

NIDEK TONOREF III AUTOMATIC REFRACTOMETER

This Autorefractor, Keratometer, Pupillometer (up to 9.5mm), Corneal Topographer, and Integrated Wavefront Aberrometer completes 20 diagnostic metrics in less than 10 seconds per eye (including angle kappa, HOAs, average pupil power, RMS value, and point spread function). Easy alignment and automatic capture of data ensures accurate readings.
Wavefront data is gathered from available zones up to a 9.5mm area, adding the capability to provide for calculation of mesopic refractions. Blue light, 33 ring, placido disc topography is gathered in one second.

Features
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.

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.
