Removing splashes of tear fluid
Tear fluid drops are usually discernible in the images as light spots.
•
Apply circular movements with the LensPen (as described in Dust
removal , page 41).
•
If the desired result is still not achieved after repeated wiping, e.g. the
bright spots remain visible, the lens surface must be moist cleaned (see
Removing severe dirt accumulation ).
Removing severe dirt accumulation
A typical cause of severe contamination is accidental contact between the
front lens and the patient’s nose when the instrument is not positioned far
enough away from the patient.
•
Use the cleaning fluid and microfiber cloth or the moist disposable cloths
provided in the cleaning set, cotton ball sticks or Safebuds.
•
If a microfiber cloth is used, spray a small amount of cleaning fluid onto
the tightly folded cloth and shake off any surplus fluid.
