Notes on Use
Before Use
•
Inspect the OCT daily. Make sure that no foreign matter is present that can affect
image readings or diagnoses.
•
Any dirt or scratches on the objective lens appear as black spots which may affect the
image quality. Check and clean the objective lens before taking an image.
•
Sudden heating of a room during winter or in cold regions may cause condensation to
form on the objective lens or on optical parts inside the OCT, resulting in an inability to
obtain optimal images. In this case, wait until condensation disappears before taking
images.
After Use
•
After using the OCT, turn off the power, attach the objective lens cap to protect the
objective lens from dust, and place the dust cover over the OCT. You cannot take
good images if the objective lens is dusty.
Cleaning and Disinfecting
•
Do not allow the blower to touch the lens.
•
Do not wipe or rub the lens if there is dirt or dust on it.
•
Do not wipe the lens with ethanol solution, eyeglass cleaner, or silicone-coated paper.
Doing so could damage the surface of the lens or leave streaks.
•
Do not clean the exterior of the OCT with lens cleaner. Doing so could damage the
exterior of the OCT.
•
Do not use alcohol, benzine, thinner, or other solvents to clean the exterior of the OCT.
Doing so damages the exterior of the OCT.
•
Do not use ethanol solution to clean the exterior of the OCT, except the forehead rest
and the chin rest. Otherwise, damage may occur to the exterior of the OCT.
•
If the chin rest paper is not being used, disinfect the chin rest for each patient in the
same manner as you do for the forehead rest.
