Frequently asked questions

What solvents can be used to clean ZEISS device surfaces?

ZEISS recommends a disinfectant such as isopropyl alcohol. Isopropyl alcohol contains 70% alcohol, which is recommended by the Centers for Disease Control and Prevention (CDC). Please refer to the device user manual for a list of other appropriate cleaning and disinfecting agents.

Can the HFA bowl be cleaned and how often?

The HFA bowl is a specialized surface and an integral part of the calibrated instrument. It is not intended to be regularly cleaned. Any frequent contact with the bowl surface, including cleaning with a soft cloth with distilled water, cleaner or 70% isopropyl alcohol, could degrade the reflective surface of the bowl, which can damage the device and impact performance. If cleaning is necessary due to possible contamination, it is critical to follow the cleaning procedure outlined in the user manual.

Can the HFA3 Liquid Lens be cleaned?

The Liquid Trial Lens may be cleaned with a soft cloth or tissue and one of the following cleaners: 70% isopropyl alcohol (rubbing alcohol) in water, or mild glass cleaner containing no ammonia.

Can the OCT lenses be cleaned?

Yes. As specified in section 11.3.4 of the CIRRUS user manual (Cleaning Heavy Contamination), lenses should be cleaned using only water, isopropyl alcohol and acetone.
