•
Use cleaning utensils only once according to the given or indicated
instructions. If the result is not satisfactory, please use a new surface or
cleaning set.
Use the following utensils for cleaning the front lens:
•
Volk LensPen ® cleaning pen (available from optical retailers or directly
supplied by ZEISS, order number 000000-0483-896)
•
Optical cleaning set (ZEISS, order number 000000-1216-071) or
cotton ball sticks or Safebuds from AF International (order number
SBU000)
Frequent causes of lens contamination
•
The main cause of simple and uncritical lens contamination is airborne
dirt particles (e.g. dust).
•
More serious contamination is caused by small drops of the patient’s tear
fluid sprayed on the front lens when blinking.
•
It is important to avoid serious contamination caused by the patient
sneezing or touching the lens surface with the finger or nose. Fatty
residue of this kind results in distinct bright areas on the image and can
only be removed by moist cleaning.
Dust removal
•
Dust or other loose particles on the lens surface can be quickly be
removed with the LensPen (brush side) or the brush provided in the
cleaning set.
•
If necessary, the entire surface may be wiped with the special felt of the
LensPen. Apply gentle pressure to the entire lens surface with circular
movements. Start in the center of the lens surface and wipe in circles
outwards towards the edge.
 Please note that upon replacement after cleaning or repeat wiping,
the protective cap of the special felt tip must be rotated three or
four times.
