3 Cleaning and disinfection of reusable
measuring prisms
CAUTION!
Risk due to improper cleaning and disinfection
The disinfectant used must satisfy two criteria:
u
For material compatibility reasons, only agents approved by
ZEISS may be used. The current material compatibility list can
be found on the ZEISS homepage and is included with the
tonometer and the measuring prisms. Should the operator
decide to employ other disinfectants or procedures of his own
accord, it must be ensured that the disinfection is not
performed with agents containing alcohol or acetone and is
never performed with UV radiation, steam or ethylene oxide.
u
In terms of the disinfection performance, all disinfectants that
are approved for instrument disinfection and that have been
tested for their efficacy against all nosocomially relevant infec-
tious agents can generally be used as long as they also satisfy
the material compatibility requirements outlined above. The
user is responsible for selecting the correct disinfectant and
employing the correct concentration.
NOTE
Damage due to improper cleaning and disinfection
The tonometer measuring prisms may be damaged during cleaning
and disinfection.
u
Use only Hydrogen Peroxyde at a 3% aqueous solution or
Sodium Hypochlorite (Household Bleach) at a 10% aqueous
solution. These two solutions have been validated with mild
soap (e.g. Palmolive 0.08%) as the cleaning agent.
3.1 Manual cleaning steps
For simple and safe disinfection, we recommend using containers
with holders for several measuring prisms. In the following,
cleaning and disinfection using Desinset by HAAG-STREIT is
described. The use of other disinfection aids is at the user's own
risk. Used instruments must be rinsed off after use before the
residues dry up.
