10.1 CLEANING AND DISINFECTION
The external surfaces of the unit’s components must be cleaned without using
abrasive products and without allowing liquids to penetrate inside the unit itself.
With the exception of the cone (see section §10.1.1), the Keratron
™
Onda’s housings
can be cleaned either with alcohol or with a damp cloth followed by a dry cloth.
10.1.1 FOREHEAD REST AND MIRES CONE
The patient places his or her chin on the chin-rest during the measurement. Before
the exam, sterile and/or biocompatible disposable paper tissues must be placed on
the chin-rest and on the forehead-rest and changed for each patient, so as to avoid
cases of possible allergy of the skin or cross infections. Furthermore, it is suggested
to periodically clean the chin-rest itself with alcohol or antibacterial disinfectant.
Similar considerations are valid for the optical head’s external black conical surface.
It can be cleaned and disinfected, being careful not to touch the two small
photoelectronic tips mounted at the external end of the cone.
For the internal portion, which contains the white/black concentric mires, cleaning
with alcohol or other liquids must absolutely be avoided. Cleaning must be performed
as follows:
Switch off the Keratron
™ Onda.
Unscrew the 2 screws on the right and left of the cone using the appropriate
socket wrench.
Grab the mires cone by its round flap with your full hand and remove it.
Press it firmly against the videokeratoscope. Note: verify that the cone is firmly
inserted and that there is no space between the rear flange and frame.
Put the two fastening screws back into position and tighten them.
Run a calibration, as described in section §7.2.
10.1.2 CLEANING THE ACCESSORIES THAT ARE NOT PROVIDED
To clean the PC, the monitor, and any other accessories, refer to the procedures
advised by the respective user manuals.
