1.6.3 Service life of reusable measuring prisms
WARNING!
How long can measuring prisms be used?
Due to the large number of variables to be considered (type and con‑
centration of the disinfectant used, number of patients, handling, etc.) it
is practically impossible to provide exact information on how often and/
or how long a measuring prism can be used under safe conditions. The
measuring prisms are stamped with an expiry date ( ). They must not
be used beyond this date. HAAG‑STREIT recommends a maximum ser‑
vice life of two years before the expiry date. This service life applies sub‑
ject to normal conditions of use, i.e., in compliance with the instructions
contained in these instructions for use. The service life starts with the first
use. The above‑mentioned time periods do not apply to damaged mea‑
suring prisms; these must be immediately replaced.

1.6.4 Tonosafe
NOTE!
Tonosafe was developed to avoid the necessary cleaning and disinfection
of measuring prisms from applanation tonometers. Tonosafe is a dispos‑
able applanation and optical duplication prism for Goldmann and Perkins
applanation tonometers, for single use.
Additional details can be found in the separate instructions for use.
1.6.5 Monthly device checks
The tonometer must be checked on a monthly basis as described in the 'Mainte‑
nance' chapter. A check will be absolutely necessary if external force is applied (e.g.,
striking or dropping the appliance).
NOTE!
If a repair is necessary, please contact your HAAG‑STREIT representative.
