The refurbished NIDEK TONOREF III is an advanced four-in-one pre-test instrument combining autorefraction, keratometry, non-contact tonometry and non-contact pachymetry within one compact system.
By bringing four essential measurements together, the TONOREF III can help streamline patient assessments, reduce movement between separate instruments and make more efficient use of valuable practice space.
Four Essential Measurements in One Instrument
The TONOREF III provides:
- Automatic refraction
- Automatic keratometry
- Non-contact tonometry
- Non-contact pachymetry
Its integrated pachymetry function measures central corneal thickness and automatically uses the result to calculate corrected intraocular pressure. This provides additional information to support the interpretation of IOP measurements during glaucoma assessment.
Automated and Efficient Operation
X, Y and Z auto-tracking assists with patient alignment, while the Auto-shot function automatically captures the measurement when the correct position has been reached.
A large, tilting 7-inch colour touchscreen provides a clear and intuitive interface. Its flexible display can also support installation against a wall or in a corner, making the TONOREF III suitable for practices where space is limited.
Advanced Refraction and Keratometry
Large Pupil Zone Imaging measures both the central refraction and a wider pupil area. Comparing these results can help assess how changes in pupil size may affect vision, including visual performance under lower-light conditions.
The Double Mire Ring keratometry system takes measurements across two diameters—3.3 mm and 2.4 mm. This helps reduce interference from the eyelids and provides additional information about the shape of the corneal surface.
A Quick Ref Measurement mode is also available for patients who may find conventional alignment difficult, including children and patients with less stable eye movement.
Patient-Friendly Tonometry
The Automatic Puff Control function adjusts the air pressure used for subsequent measurements based on the previous result, helping deliver the minimum pressure required.
Combined with a quieter air-puff mechanism and gentle nozzle design, this helps make non-contact tonometry more comfortable and less intimidating for patients.
Additional Clinical Assessment Tools
The TONOREF III includes objective accommodation measurement using a fixation target that moves automatically from distance to near.
Its retroillumination imaging function can also be used to assess media opacity, providing useful supporting information during routine examinations and cataract assessments.
