Lubrication

Apply a small amount of surgical grade lubrication oil to hinges, joints and moving parts to prevent build up, staining, corrosion and wear.

Inspection

All instruments in the tray should be checked after each procedure whether they were used or not for damage or malfunction. Use of an appropriate microscope is recommended due to the delicate and precise nature of the instruments. Any damaged or worn instruments must be removed from the tray at this stage and returned to John Weiss for repair. After cleaning visually inspect all surfaces, cannulations, ratchets, joints, holes and lumens for complete removal of soil and fluids. If any soil or fluids are still visible, return the instruments for repeat decontamination.

Sterilisation

Protective caps provided with instruments are not suitable for high temperatures and must be removed before sterilisation, as there is a possibility that the cap may melt. Please note that silver products such as some Cannulae and Lacrimal Probes are subject to tarnishing and discoloration. This will in no way affect the performance of the instrument.

Only sterilise a clean instrument. The preferred method of sterilisation is moist heat in an autoclave at a temperature of 132° to 137°C for a minimum holding time of 3 to 4 minutes. Follow the guidelines in HTM 2010. For effective steam penetration, use perforated Ophthalmic Trays and open all ratchets and locks on the instruments. Steam at a pH of 7 is ideal for sterilisation, as HTM 2031 refers. Instruments should not be taken from the Sterile Services Department until properly cooled down, as rapid lowering of temperature will cause condensation and may cause corrosion. Instruments must be completely free of moisture before storage.

Storage

Instruments should be secured in recommended John Weiss Ophthalmic Trays with silicone matting to prevent movement. Ensure that cutting edges are protected, and do not exceed recommended number of instruments, as specified for the type of instrument tray being utilised. Wrap trays using an appropriate method. Ensure instruments are dry before storage, and stored in a dry, clean condition.
