    Why is the auto-tracking or auto-shot function not working on my Nidek Medical Equipment?
    • J
      Jennifer SparksAug 20, 2025
      The auto-tracking or auto-shot function may not be turned on, so press the appropriate button to activate it. Room illumination reflecting on the cornea can also interfere with these functions; try changing the location and measuring again. Additionally, these functions may not work on certain eyes, such as those with keratoconus or recent corneal surgery. In such cases, turn off the auto-tracking function and proceed with the measurement. If the patient has substantial ocular ataxia or cannot fixate their eyes, disable the auto-tracking function. If the device is near a window with direct sunlight, relocate it to avoid light interference.

    What to do if a measurement error appears on my Nidek Medical Equipment?
    • A
      Ashley DixonAug 21, 2025
      A measurement error may occur if the patient blinked during measurement; instruct them to avoid blinking and try again. The eyelid or eyelashes may be obstructing the measurement, so ask the patient to open their eye wider, or gently lift the lid without pressing the eyeball. If the pupil is too small, have the patient sit in a dark room to allow it to enlarge. Also, if measuring an IOL-implanted eye or one with a contact lens, turn on the appropriate setting. Finally, the data may simply exceed the measurable limit.
