Instructions For Use (continued)
Alignment & Measurement (continued)
The Reichert 7 features a fully automated alignment system that enables the
instrument to align itself to the apex of the patient’s left or right eye. This innovative
system makes the measurement process quicker and more comfortable for the patient.
Perform the following steps to take a measurement of the patient’s eye.
1. Instruct the patient to locate the air tube inside the red circle on the end of the
nosepiece.
2. After they have located the air tube, have the patient nd the green target inside
the air tube and then slowly lean forward until their forehead is on the soft pad in the
middle of the Forehead Rest. Refer to next page.

Instructions For Use (continued)
Alignment & Measurement (continued)
Note: If the patient cannot see the green target, use the canthus marks on the sides of
the instrument to set the vertical alignment of the eye and then have the patient
move forward until the center of their forehead is against the Forehead Rest
pad.
Note: The patient should be seated comfortably on the patient side of the instrument.
Note: The patient should be positioned in a way that encourages them to lean forward
with their chin as close to the instrument as possible. This will reduce the
difculties associated with misalignment and low condence readings
