Usage of non-contact tonometer

As a commonly used tool for measuring intraocular pressure, non-contact tonometer is relatively simple and convenient to operate.

Firstly, check if all parts of NCT are in good condition, with the power switch turned off. Insert the power plug into a 220V grid socket and turn on the power switch.

Let the patient relax and feel as comfortable as possible, sit in front of the tonometer, place their head on the headband, and keep their forehead tightly pressed against the headband. Remind patients to keep their eyes open as much as possible during the examination and focus on the red bright spot inside the detection nozzle. Do not avoid the wind blowing on their eyes, as it will not harm them. The inspector adjusts the instrument control lever and focuses, takes the average of three consecutive tests, and prints out the results after the measurement is completed. If the display screen does not show the numbers, it may be due to inaccurate gaze, excessive tears, or other reasons. Adjustments can be made before measuring again.

During the testing process, there is no need to apply medication or the like. The non-contact tonometer mainly uses air flow when spraying, which measures intraocular pressure through the impact of air flow, not radiation, so it does not cause any harm to our eyes.
