Double Cleaning; Sterilization - MORIA ALTK Manuel Utilisateur

3. DOUBLE CLEANING

- 1 manual cleaning * (or use an automatic washer, provided the machine does not recycle the cleaning
st
fluid).
- Carefully rinse using tap water.
- Immerse the device in a non-aldehyde detergent-disinfectant solution (different or prior bath).
- 2 manual cleaning * (or use an automatic washer, provided the machine does not recycle the cleaning
nd
fluid).
- Carefully rinse with filtered distilled or osmosis water.
- Wipe the device with a non-fabric, lint-free, single-use swab. Once the components are completely dry,
package them promptly to avoid contamination. Dry the inside of the base of the device using filtered
compressed air.
Important: Change the bath after each use.
* Manual cleaning: Mechanically clean the device for a minimum 2 minutes using soft brushes. (You must
not use metal brushes). Do not use abrasives or scrapers to clean the parts. Doing so will reduce
precision, produce scratches, and damage the metal surfaces.
Note about unconventional transmissible agents (UCTAs):
For France, follow the recommendation of the Health Ministry concerning the deactivation of UCTAs (DGS/5
C/DHOS/E 2 n° 2001-138 of 14/03/01).
- Immerse the device immediately after removing from the block into a non-aldehyde preferably
enzymatic detergent-disinfectant solution, for a minimum of 15 minutes, according to the manufacturer's
recommendations, then rise the devices.
- Then immerse the device in a soda solution (1 N) for one hour. Only the tonometer must not be
cleaned with soda.
- Finally, rinse manually three times in succession (with tap water), with a pH check at the first rinse to
avoid any risk of burning (pH neutral). The final rinse must be done with microbiologically controlled
water.
If the pH is not neutral, rinse several more times until the pH is acceptable (close to pH7).
- Wipe the device with a non-fabric, lint-free, single-use swab and put it back into the normal disinfection/
sterilization circuit.

4. STERILIZATION

Sterilize (except for cutting lenses) using a self-regulating sterilizer (steam sterilizer) at minimum 134°C
(273°F) for 18 minutes.
To remove the water, it is very important to use the self-regulating sterilizer's drying program.
The parts must be removed from the self-regulating sterilizer immediately after sterilization and must
be cooled to room temperature before use.
Avoid thermal shock, as it can weaken the material.
IMPORTANT ! Leaving residual humidity in the ALTK chamber can produce oxidation. Make
sure that the parts are completely dry before storing them, by passing them through the self-
regulating sterilizer's drying program (sterilizers without a drying cycle are not recommended).
