Figure 7-26: The external PC is not present
In both cases the Keratron
™ Onda asks the operator whether the image must be
discarded or stored locally for subsequent transfer. The maximum number of
images that can be stored locally is 8.
If you respond [Yes], from that time on will appear an indicator (1 in Figure 7-27)
that keeps count of the number of images stored locally and a button [Send to PC]
(2 in Figure 7-27) o be pressed at the end of the test to send the entire sequence of
images to the external PC all together at the same time.

In practice the operator can acquire up to 8 images in rapid succession, transmitting
them to the external PC with the button on the
joystick
itself, or stop to process
them locally and decide what to do with them later.
Figure 7-28 shows, for example, the image of the calibration sphere with the
curvature map.
On the right side of the screen are listed the values of power or curvature in
diopters (Power), the distance from the centre in mm (Distance), the curvature
radius in mm (Radius), the meridian (Meridian) and the height (Height) of the point
shown by the pointer that can be easily placed on the curvature map. Also present
are the
Sim K
with the maximum (red) and minimum (blue) curvature axes and the
astigmatism (Diff.), the dimension of the pupil (Pupil) and its offset (Offset) from
the vertex in mm and the
E-values
, with eccentricity and apical radius (in mm), on
the respective meridians, curved (red) and flat (blue).
