Device User Manual 87
• Do not use Sensor Strips with patients who are allergic to the Sensor Strip gel.
• Avoid use when the orbit structure is damaged or surrounding soft tissue has an open
lesion.
Some patients may feel discomfort when viewing the flickering light that the RET
eval
device
creates to test their eyes. This discomfort usually subsides quickly when the test procedure
completes.
Cleaning and Disinfection
WARNING: Consult the cleaning agent and germicidal cleaner agent manufacturer instructions
for their proper use and germicidal efficacy prior to their use.
CAUTION: Do not submerge the device in liquid or allow liquid to enter the interior of the device
as this could damage the electronics. Do not use automatic cleansing machines or sterilization.
CAUTION: Follow these instructions and only use the cleaning or germicidal cleaner agent types
listed or damage may occur.
Cleaning the ganzfeld
The white interior sphere that the patient looks into (the ganzfeld), should be cleaned when there
is visible dust inside or when the device fails to calibrate at the start of a test.
The ganzfeld can be cleaned with a compressed gas air duster to remove dust. A damp cloth
moistened with water or isopropyl alcohol may be used if compressed gas doesn’t work. Liquid
cleaners may damage the LED lights and camera inside it.
Cleaning and disinfecting the exterior
Cleaning of the patient contacting parts of the device (eyecup and Sensor Strip lead) is
recommended between patient uses.
The RET
eval
device is chemically compatible to wipes containing 70% isopropyl alcohol and with
wipes containing alkyl dimethyl benzyl ammonium chloride. The use of other wipes may damage
the device.
Step 1. Remove all visible soil by wiping all exterior surfaces with a compatible wipe. Ensure
that all visible contamination has been removed.
Step 2. Disinfect using a germicidal wipe labeled suitable for use on healthcare equipment and
capable of low or intermediate level disinfection, following the procedures and contact
time recommended by the germicidal wipe manufacturer.
Step 3. Inspect for any visible damage prior to use. Discontinue use if any abnormalities are
found.
Replacement eyecups and Sensor Strip leads are available. See Purchasing Supplies and
Accessories on page 101.
