During Surgery

Immediately after each procedure, all instruments in the surgical tray should be wiped clean with a John Weiss Sterile Instrument Wipe moistened in demineralised/sterile water. Cannula, suction tubes and other instruments with lumens should be flushed through immediately after use. Demineralised/sterile water used for flushing should be cool to avoid coagulation of proteinaceous material. Diamond Knives require special care (see Diamond Knives).

Immediately After Surgery

Immediately after surgery, all instruments in the surgical tray should be wiped clean with a John Weiss Sterile Instrument Wipe moistened in demineralised/sterile water. All cannulated instruments must be ultrasonically flushed or brushed through with an appropriate cleaning brush. Ultrasonic cleaning for 5 – 10 minutes with a neutral pH ultrasonic cleaning solution is recommended for thorough cleaning of almost all ophthalmic instruments. To prevent ion transfer, instruments should be sorted according to their material and type. Titanium and stainless steel should not be mixed in the same ultrasonic cleaning cycle. Instruments must be completely free of moisture before sterilisation.
