11 Measuring Procedure
Instruction Manual Pentacam® AXL (G/70100/EN 1121 Rev04)
43 / 85
Adjustment
Move the cross slide towards the patient until the Scheimpflug
image shows the cornea of the eye that you are examining.
The image is sharpest when the red dot coincides with the red line
in the Scheimpflug image (relevant for Pentacam® without an axial
length measurement).
Focus the pupil image by moving the joystick towards the
Pentacam® or away from it.
Adjust the left/right position of the Pentacam® AXL and its height
setting.
Move the joystick to the left or right and rotate the joystick
clockwise or anticlockwise.
The tentative final position of the camera is reached when the four
infrared LEDs are sharp and the red cross hair is in the center of the
pupil.
Ask the patient to widen his or her eye and not to blink.
The Pentacam® AXL triggers the measurement automatically.
