Automatic Calculation of Corrected IOP

The NIDEK TONOREF III is the world's first combined automatic refractometer,
automatic keratometer, non-contact tonometer, and non-contact pachymeter.
With this device, we can offer patients five simultaneous examinations in a short time and with maximum comfort. It features high measurement accuracy, accommodation measurement and opacity assessment, user-friendly operation, and a compact, ergonomic design.

Automatic Calculation of Corrected IOP

TONOREF™ III provides automatic calculation of compensated IOP (intraocular pressure) based on central corneal thickness. IOP is most often overestimated in thick corneas and underestimated in thin corneas. A corrected IOP value allows for a more accurate assessment.

Accommodation Measurement

Accommodation measurement helps assess conditions such as pseudomyopia, eye strain, and accommodative palsy. This measurement of accommodation is performed by directing the patient toward a target approaching from a distance. An artificial intelligence algorithm detects the patient's response and reduces the measurement time in patients with slow or poorly accommodative reactions.

Simple Opacity Assessment

The retroillumination image allows for the assessment of the opacity of the optical system. Cataract indices indicate the degree of opacity and help assess the progression of the abnormality.

APC - Pressure Control System

The Tonoref III is equipped with a gentler and quieter air puff (Automatic Puff Control). The new mechanical design reduces noise and airflow during the examination, while being less noticeable to the patient than in the previous Tonoref II model.

Zonal Pupil Imaging

A unique method of refraction measurement characterized by the highest accuracy. It allows for the measurement of central refraction and dilated pupil refraction. Differentiation of the measurement allows for the estimation of the difference in refraction between daytime and nighttime vision.
