3.3.6 Browsing and editing keratometer measurement
a) Browsing measurement values
■ The corneal irregular astigmatism display function is a simple
measurement using keratometer measurement. This function does not
detect all cases of corneal irregular astigmatism. Measurement itself or
correct measurement may not be performed for some corneal shapes
such as if there is a partial problem on the corneal shape.
■ Because the corneal irregular astigmatism display function requires more
information than keratometer measurement, corneal irregular
astigmatism may not be measured even though keratometer
measurement can be performed.

1) Touch the "Kerato" button (1) on each view screen to open the kerato view
screen (Fig. 2).
The default view for measurement position is determined by the fitting
formula used in the measurement.
Immersion shows φ2.5 mm. Other fitting fomula shows φ3.0 mm.
