Detailed Information

 

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.
