Care & Cleaning for Vitreoretinal Instruments
These instruments have a precision delicate mechanism inside. Intraocular fluids will enter this mechanism during surgery. If these fluids are not promptly and properly cleaned out, it will lead to corrosion and the possibility of instrument malfunction. Proteins may also accumulate inside of the mechanism.
Cleaning:
- Unscrew the tip from the handle, then attach flushing adapter 12-000.
- Ultrasonically clean both parts, if possible.
- Flush the tip with distilled or deionized water by connecting syringe filled with water to adapter.
- Flush the tip with alcohol. This will remove the water and facilitate drying.
- Dry the tip by forcing one or two syringes full of air through tip. Pressurized air is recommended, as it flushes out debris and fluid more efficiently than syringe forced air. Thoroughly dry handle, tip and cup.
- Force special thermoresistant instrument milk through the tip, as in No 3 above.
- Dry with air as in No 5 above.
- Handle should be soaked in distilled or deionized water for two minutes.
- Dry with surgical sponge.
- Lubricate joints in handle with instrument milk and work the mechanism.
