NIDEK TONOREF III Ref/Kerato/Tono/Pachymeter
Model: AR1NKRKT-III
The NIDEK TONOREF III is combines auto refractometer, auto keratometer, non-contact tonometer and non-contact pachymeter in one user-friendly device.
- 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 that moves from distance to near.
- The retroillumination image allows evaluation of media opacity.
- 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.
- Keratometry measurements performed with the mire ring method reduce interference from the eyelids. The TONOREF III performs measurements at diameters of 3.3 mm and 2.4 mm. Comparison of the two values allows a better understanding of the cornea shape.
