NIDEK TONOREF III – 4 IN 1
Features include:
Automated calculation of corrected IOP
Opacity assessment
The retro illumination image allows evaluation of media opacity
Large pupil zone imaging method
Measures the central refraction and a large area refraction. The difference in the measurement allows assessment of the effect of pupil size on vision under mesopic conditions.
Double mire ring Method
Keratometry measurements performed with the mire ring method reduces interference from the eyelids. The device 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.
Automatic Puff Control (APC)
In subsequent measurements, the APC function performs the measurement with the minimum air pressure based on the previous measurement data. Now with a softer and quieter air puff.
Gentle nozzle design
A gentle nozzle design reduces patient’s perception of physical pressure.
