10.2 STERILIZATION
The Keratron
™
Onda topograph aberrometer, the computer, and the accessories
used do not require sterilization, because they must not come into contact with the
patient.
10.3 MAINTENANCE
Periodically verify the good condition of the connection cables and the power cables.
To maintain system safety, the compliance to EN60601-1 leakage current limits
should be tested at least once a year. Please, inquire with the Bioengineering
Department in your clinic or with your local Optikon 2000 S.p.A. Distributor/Service
Center.
In topography periodically acquire the calibration sphere and compare the curvature
value you obtain with the value listed on the sphere itself). If the difference between
the two values is greater than ±0.3 D it is advisable to recalibrate the instrument.
It is advisable to periodically repeat the calibration using the appropriate sphere,
especially when the instrument is moved or when the mires cone has been removed
and cleaned as described in section §7.2.
The calibration of the aberrometry is performed in the factory and cannot be
repeated by the user.
However, the user can periodically verify the consistency of performance by
measuring the provided calibration sphere as described in section §7.2.
