Reichert 7CR User manual

Perform the following steps to take a measurement of the patient’s eye.
Set the height of the table so the canthus
marks on the sides of the instrument are
level with the patient’s eyes. The patient
should be seated comfortably and posi-
tioned in a way that enables them to lean
forward without straining.
Slide the headrest fully to the left or right.
Have the patient locate the red LEDs
surrounding the air tube and lean forward
so that the center of their forehead rests
rmly in the middle of the rubber forehead
pad.
Make sure the patient is able to see all,
or some, of the red lights. Explain to the
patient that a green light will move into view
during measurement. Ask the patient to
blink a few times then hold both eyes open
when the green light appears.
Touch the MEASURE or TRIPLE MEA-
SURE icon to begin the measurement
process.
Note: If the instrument is unable to complete its alignment and measurement process, it
may be necessary to:
• Reposition the patient and obtain optimal alignment
• Ask the patient to remain still and try not to move
• Remind the patient to keep both eyes wide open and to move his/her chin as close to
the instrument as possible.

During the positioning process, the
operator’s screen will change and
look similar to the picture shown
on the right. Once the position-
ing system is aligned, the airpuff is
delivered to the eye and the reading
is displayed on the screen.
After the measurements are com-
pleted for the rst eye, instruct the
patient to move their forehead away
from the instrument.
There are several options available
at this point:
a. The Forehead Rest may be
slid to the opposite side to take
measurements on the other eye.
b. The data can be printed by touching the PRINT icon.
c. All data may be cleared and other measurements taken, by touching the CLEAR
DATA icon.
Denitions and Interpretation of the measurement values:
Denitions and Interpretation of the measurement values:
• IOPg - Goldmann-correlated IOP. IOPg agrees, on average, with the results obtained
from an expertly executed, properly calibrated Goldmann Applanation Tonometer.
• IOPcc - Corneal Compensated IOP. IOPcc takes the biomechanical properties of the
cornea into consideration, providing an indication of intraocular pressure that is less
inuenced by properties such as corneal visco-elasticity and thickness.
• When IOPcc is higher than IOPg, this indicates that the IOP for this patient may
be being understated using traditional methods of tonometry.
• When IOPcc is lower than IOPg, this indicates that the IOP for this patient may
be being overstated when using traditional methods of tonometry.
• Score: An advanced signal “scoring” process is employed in the 7CR to objectively
determine the reliability of the measurement data. On a scale of 0 to 10, the higher
the score, the more reliable the measurement data.
