Automated calculation of corrected IOP
The TONOREF™ III provides the automated calculation function of the corrected IOP based on the central corneal thickness.
Objective measurement of accommodation is performed with patient’s focusing on a target which moves from distant to near.
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.
