Using the dropdown menu that can be activated by pressing the
touchscreen
for a
longer amount of time, it is possible to modify the image of the patient’s refraction
(Figure 7-46). The cylinder can be displayed with positive, negative, or automatic
values; the vertex can be selected on the cornea (0 mm), at 12 mm or 14 mm
(Figure 7-47); and it is possible to select the resolution from among 0.01 mm, 0.12
mm, or 0.25 mm (Figure 7-48).

If the "Scout" window is open and you press the print symbol on the upper bar (1 in
Fig. 7-36), it is possible to print the screen using the preset printer of the PC.
By pressing the two “RX” buttons (2-3 in Fig. 7-36) it is possible to recalculate the
patient's refraction using the photopic (VL) pupil diameter or the scotopic (IR)
diameter, as calculated in the corresponding map.
Note: the pupil that is actually set is limited in the upper section to the one
measured by the wavefront sensor and in the lower section to 2mm.
