NIDEK launches TONOREF III Auto Ref / Kerato / Tono / Pachymeter


NIDEK CO., LTD., a global leader in the design, manufacture, and distribution of ophthalmic, optometric, and lens edging equipment, is pleased to announce the launch of the TONOREF™ III Auto Ref / Kerato / Tono / Pachymeter.

The TONOREF™ III combines the functionality of an auto-refractometer, auto-keratometer, non-contact tonometer and non-contact pachymeter into one device. NIDEK, the first manufacturer to combine an autoref/keratometer with a non-contact tonometer, now introduces a single combination unit for high measurement accuracy, clinically important functions and a user-friendly design. With the TONOREF™ III, multiple measurements can be performed at one sitting, increasing patient comfort and maximizing clinical efficiency. The space saving design of the TONOREF™ III ensures effective use of office space.

A new feature is the incorporation of a non-contact pachymeter to the TONOREF™ III. This function enables automated calculation of corrected intraocular pressures (IOP) based on the pachymetry data. Generally, IOP is overestimated for thick corneas and underestimated for thin corneas. The corrected IOP value is important for clinical management of patients. The TONOREF™ III maintains the same compact size as its predecessor even with the addition of the non-contact pachymeter.

Additionally, the TONOREF™ III incorporates two clinically important functions, accommodation measurement and opacity observation of the optical media of the eye.

Utilizing 8 years’ worth of technical achievement since the release of the previous model, NIDEK has enhanced the conventional refraction and keratometry measurement functions by incorporating large pupil zone imaging and double mire ring methodology which is certain to maintain our position as a market-leading manufacturer of autoref/keratometers.

With these functionalities and the design above, the TONOREF™ III will ensure patient comfort while optimizing clinic efficiency.
