Aligning the Phoroptor Head

Once the Phoroptor Head is powered on and completes an initialization process, an exam can be
performed.
1. Place the Phoroptor Head in front of the patient, centering it
in front of the patient's eyes.
2. Position the patient's head against the forehead rest.
3. Check the illuminated bubble level to ensure the Phoroptor
Head is level. Adjust by rotating the Thumb Screw on the top
of the Phoroptor Head.
4. Adjust the Phoroptor Head to line up with the patient's left
eye.
5. Using the Controller, adjust the pupillary distance between
the right and left apertures on the Phoroptor Head.
Note: If the Auto Refractor or Lensmeter data transmits PD
measurements when the data is brought in as a starting
point for the refraction, and PD was not manually
adjusted, the Phoroptor VRx Head automatically moves
to adjust to that PD.
6. Press the PD button, or tap PD at the top of the screen. Both apertures display the crosshair lenses.
Use the crosses in the lenses to center the patient's pupils in each aperture.
7. Turn the CONTROL KNOB to the right to increase the pupil distance and to the left to decrease pupil
distance.
Binocular Adjustment
Turn the CONTROL KNOB to increase or decrease PD in 1 mm increments.
Monocular Adjustment
Press the R or L button, or tap R or L on the screen to adjust PD for the right or left eye. Turning
the CONTROL KNOB adjusts PD in 0.5 mm increments.
8. Look into the Corneal Vertex Distance Windows and line up the corneas by turning the forehead rest
knob, so the target line and the target mark superimpose. (Please refer to Figure PE-02.)
Note: The default vertex distance is 16 mm.
9. Adjust the height of the lens banks by centering the left aperture in front of the patient's left eye, and cen-
tering the right aperture with the patient's right eye by turning the Asymmetrical Height Adjustment Knob.
