TONOREFTM III
Brand: Nidek – Nhật Bản
The space saving TONOREFTM III is a comfortable and efficient upgrade to your practice
Refraction
Large Pupil Zone Imaging Method
The use of a wide area measurement within the pupil increases the accuracy of measurement that is more indicative of the subjective refraction. The large pupil zone imaging method measures the central refraction and a large area refraction. The difference in the measurement allows assessment of the effect of pupil size* on vision under mesopic conditions.
Super Luminescent Diode (SLD) Light and Highly Sensitive CCD Camera
The system combining the SLD Light and highly sensitive CCD camera significantly improves measurement capability even in dense cataractous eyes.
Optimal Fogging to Minimize Accommodation
Fogging is performed after correcting the patient’s astigmatism with built-in cylinder lenses. This minimizes the effect of accommodation even of patients with high astigmatism.
Keratometry
Double Mire Ring Method
Keratometry measurements performed with the mire ring method reduces interference from the eyelids. The TONOREFTM 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.
Pachymetry
Non-contact optical pachymetry is used to measure corneal thickness.
Tonometry
Automated Calculation of Corrected IOP
The TONOREFTM III provides the automated calculation function of the corrected IOP based on the central corneal thickness. Generally, the IOP is overestimated for thick corneas and underestimated for thin corneas. The corrected IOP value allows a more accurate assessment.
Patient-friendly Air Puff
- Automatic Puff Control (APC) : In subsequent measurements, the APC function performs the measurement with the minimum air pressure based on the previous measurement data.
- Softer and Quieter Air Puff : The new mechanical design of the TONOREFTM III reduces noise and air intensity to achieve a more gentle air puff over that of the TONOREFTM II.
Accommodation Measurement
The accommodation measurement helps to assess such as pseudomyopia, eyestrain, and accommodative palsy. Objective measurement of accommodation is performed with patient’s focusing on a target that moves from distance to near. The artificial intelligence algorithm detects the patient’s response and reduces the measurement time in patients with a slow or weak accommodative response.
Opacity Assessment
Retroillumination Image and NIDEK Cataract Indices
The retroillumination image allows evaluation of media opacity. NIDEK cataract indices indicate the severity of the opacity and helps to assess the progression of pathology.
Easy to Use Screen
- Tiltable 7-inch color LCD touchscreen
- Summary Display Summary screen allows easy and quick confirmation of patient data.
Easy Access to Patients Eyelids
The radical cut design allows direct access to patient eyelids.
3-D Auto Tracking and Auto Shot
The 3-D auto tracking and auto shot provide faster, simpler, and more accurate measurements. Once alignment is completed, the measurement starts automatically.
Joystick for Flexible Alignment
The joystick helps the operator make fine adjustments during alignment to improve the precision, even for eyes with poor fixation which cannot be tracked with automated tracking systems.
Wireless LAN (WLAN)
The TONOREFTM III connects with PC and peripheral devices using wireless LAN (WLAN)*, LAN cable, RS-232C cable, EyeCare Card, barcode scanner or magnetic card reader.
Automatic Anti Dew Heater
Automatic anti dew heater for measuring windows prevents condensation to provide accurate measurements in cooler rooms.
