■ Sterilize the biometry probe before use.
■ Do not use the biometry probe with its contact section
damaged.Measurement error may occur, and the cornea may be
injured.
■ Immersion attachment is a disposable part.Do not reuse it.
Otherwise, you may contract diseases.
■ The converted acoustic velocity directly affects the measurement
data. Check that the desired value is set before starting
measurement.
■ Check the settings in contact mode and immersion mode before
starting measurement.In immersion mode, apply an ultrasound
media such as cornea protective agent so that the clearance
between the cornea and the contact section of the biometry
probe is approximately 2.0 – 5.0 mm.
■ Be very careful not to apply pressure to the cornea when taking
measurement.Also, do not apply too much cornea protective
agent if used. The measurement data may be affected.
■ The automatic measurement function is an auxiliary function to
take measurements more easily.This is not a function for making
actual clinical judgments.
■ Be sure to touch the "New" button to delete all the measurement
data of the previous patient before measuring another patient.If
new measurement is started without deleting the previous data,
the measurement data of the previous patient may be included.
