Product Information
Overview
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 that moves from distance to near.
Opacity assessment
The retroillumination image allows evaluation of media opacity.Large pupil zone imaging methodThe 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 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 puffAutomatic 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 puffGentle nozzle designA gentle nozzle design reduces patient’s perception of physical pressure
