<Measurement procedures>
1) Switch the measurement mode to "REF/KRT."
* Touch the “KRT” button when conducting keratometric
measurement only and the “REF” button when conducting
refractormeter measurement only.
2) Perform alignment and take measurements with the joystick
or the joystick button the measurement screen.
If Auto Shot is turned on, measurement will start after
alignment completes. The keratometric measurement is
performed first, followed by the refractometer measurement.
3) Once data from the keratometric measurement and
refractometer measurement are obtained for the specified
number of measurements, measurement completes.
3.2.3 Measuring intraocular pressure and corneal thickness
This instrument calculates the intraocular pressure based on the
Goldman applanation tonometer. However, it is recommended to
take measurements using the Goldman applanation tonometer if
more accurate measurements are needed.
Be sure to set the nozzle limiter for every intraocular pressure
examination to ensure the safety of the patient. Otherwise, the
nozzle may come into contact with the patient, resulting in injuries.
Check the distance between the eye and nozzle from the side when
setting the nozzle limiter so that the nozzle does not come into
contact with the patient.
This instrument adopts optical measurements for corneal
thickness. It is reported that measurements of corneal thickness
may vary depending on measurement methods including
ultrasonic type measurement. Be sure to carefully evaluate
measurement values by adequately taking correlation of
