A tonometer is a diagnostic tool used by eye care professionals to measure the intraocular pressure (IOP) inside a patient's eyes. A patient's IOP can help an ophthalmologist or optometrist determine a patient's risk for developing glaucoma — a disease that damages the optic nerve of the eye, usually resulting in vision loss or even blindness. A non-contact tonometer uses a small puff of air (which is why it's many times referred to as the "puff test") to measure an eye's pressure. Known as pneumotonometry, the air puff flattens the patient's cornea in a non-invasive way, meaning eyes do not need to be numbed prior to the test.

| Description | Automatic calculation of compensated IOP
The IOP compensation is automatically calculated with automatically measured patient's central corneal thickness.
APC (Auto Puff Control)
The APC achives a quieter and softer air puff for patient's more | The NT-1 series includes an innovative line of devices that provide reliable non-contact tonometry and pachymetry.
The NT-1p and NT-1 perform fully-automatic measurement and include an air-nozzle contact sensor to ensure patient safety. Monitor tilt | IOP compensation by corneal thickness (only for NT-530)
The IOP compensation can be calculated with manually entered patient's central corneal thickness.
APC (Auto Puff Control)
The APC provides a quieter and softer air puff for patient's | The TONOREF™ III combines the functionality of an auto refractometer, auto keratometer, non contact tonometer and non-contact pachymeter into one device. Multiple measurements can be performed at one sitting, increasing patient comfort and maximizing |
| Features | - Enhanced combination unit of non contact tonometer and pachymeter
- Automatic calculation of compensated IOP
- Advanced APC (Auto Puff Control) and noise reduction for comfortable tonometry measurement
- Tiltable 5.7-inch color LCD for user-friendly operability
- 3-D auto tracking, auto shot, and auto complete
- The ACA mode allows the operator to capture an image of the
anterior chamber angle with the Scheimpflug image.
| Fully-automatic measurement*1
Simply by placing the chin on the chinrest, NIDEK eye detection camera automatically detects the position of the eyes and measurement starts without pressing any button. Gentle voice guidance (available in 9 languages) facilitates smooth measurement for any operator.
-Air-nozzle contact sensor
A message appears to alert the user if there is eyelid/corneal contact with the air nozzle during measurement. The measuring unit automatically backs away from the patient’s eye, and the measurement stops for patient safety.
Reliable tono/pachymeter*2
-Automatic Puff Control (APC)
In subsequent measurements, the APC function performs the measurement with the minimum air pressure based on previous measurement data.
-Gentle nozzle design
A gentle nozzle design reduces patient’s perception of physical pressure.
-IOP correction based on central corneal thickness
IOP values are automatically calculated by compensating for the patient’s central corneal thickness.*3
Flexible and space-saving design
Since the screen can be freely tilted and swiveled, the device can be placed anywhere in an examination room; installation against a wall or in a corner is now possible.
A variety of options to meet your needs
-Joystick
Models are available with or without a joystick. The 4-direction button of the newly-designed joystick allows smooth movement of the measuring unit forward, backward, right, or left.
-Hand-held control (wired/wireless)
An ergonomically designed palm-fit controller offers a unique handling experience.
-Tablet control software
If a tablet is used as a controller, screen mirroring allows any of the devices in the NT-1 series to be operated remotely with the same accuracy and comfort.
*1 Available for the NT-1p and NT-1
*2 Pachymetry is available for the NT-1p. For the NT-1, the corrected IOP is displayed by entering the patient‘s central corneal thickness.
*3 Available for the NT-1p. For the NT-1, the corrected IOP is displayed by entering the patient‘s central corneal thickness.
