2.7 Service life

How long can measuring prisms be used?

 CAUTION!

Risk of exceeding the maximum service life

Exceeding the maximum service life of the tonometer measuring
prisms may result in injury to the patient.

u

Do not use the measuring prisms beyond the expiration date.

u

Immediately replace damaged measuring prisms.

Due to the large number of variables to be considered (type and
concentration of disinfectant used, number of patients, handling,
etc.) it is practically impossible to specify how often and/or long a
measuring prism can be used under safe conditions. The measuring
prisms carry an expiry date ( YYYY-MM). They must not be used
beyond this date. ZEISS recommends a maximum service life of two
years before the expiration date. This service life applies under
normal conditions of use, i.e. when used in accordance with the
instructions contained in this user manual. The service life starts
with the first use. The above periods do not apply for damaged
measuring prisms; these should be replaced immediately.
