30 / 85 Instruction Manual Pentacam® AXL (G/70100/EN 1121 Rev04)
If "Request 6x Alignment" is activated, the axial length measurement
starts only if the patient is fixating correctly during the complete scan.
After the Pentacam® AXL is aligned properly, the measurement starts
automatically.
"Request 6x Alignment" deactivated means: The axial length
measurements are performed without any interrupt.
"Request 6x Alignment" is activated by default and should just
deactivated if the patient has problems to fixate the red blinking light.
[Enh. Dyn.] checkbox in the "3D Scan" group box
Activating the "Enh. Dyn." function prolongs the exposure time per
Scheimpflug image. The advantage is an accurate representation of
phakic IOLs. If you select this recording mode, colours and
evaluations are neither calculated nor displayed.
"Fixation Target" slider
Use of the "Fixation Target" enables a better fixation of the patient.
For this, the active "Fixation Target" (8), i.e. the LED blinking red in
the middle of the blue slit, can be shifted in steps of 0.5 D. The object
is to offset defects in the patient’s vision and ensure a simpler
method of fixation.
