It is the hospital's responsibility to ensure that all personnel involved in the central sterilizing services department have been well educated and trained to effectively clean and disinfect the delicate instrumentation. To implement best practices, a standard operating protocol should be developed for ophthalmic instrument cleaning, processing, and preventive maintenance. As a reminder, all standard operating protocols should be reassessed annually and updated, if necessary, to reflect the most current evidence‐based guidelines. Refer to the manufacturer's recommended instructions for the instruments, cleaning agent, and sterilizer. Failure to comply with the instructions as indicated will weaken the effectiveness of the cleaning procedure. Gloves are required to be worn when handling instrumentation. A new pair should be donned whenever transitioning from handling used instruments to clean instruments. It is recommended that soiled instruments begin soaking in a basin immediately post‐procedure to soften organic material prior to manual or mechanical cleaning. Instruments should be submerged in tepid water and an enzymatic cleaning detergent solution. Refer to the manufacturer’s instructions for the instruments for the type of water preferred and an approved enzymatic cleaner. Avoid mixing regular surgical instruments with ophthalmic instrumentation due to their fragility. Soft bristled brushes can be used when manually cleaning instruments. Flush lumens and cannulas with a 20‐cc syringe filled with distilled water at least three times. Without overlapping, the instruments should be placed back into their respective cases, together with the silicone dividers for protection during the mechanical cleaning process. All hinged instruments must be fully opened before transfer to the ultrasonic cleaner. After the clean and rinse cycles are completed, the instruments should be dried and lubricated as directed by the manufacturer's instructions. Instruments should be inspected after each cleaning process leading up to packaging. Instruments can be placed back into the metal instrument cassette once fully dry. Cassettes can be packaged in an appropriately sized sterilization wrap according to the size of the cassette. Paper/plastic sterilization pouches are acceptable forms of packaging for loose, lightweight instruments, as long as all excess air is removed before the pouch is firmly sealed. Remember to include a chemical indicator strip on the inside and a piece of chemical indicator tape on the outside of all packaged items to confirm that sterilization parameters have been successfully met both internally and externally. Some newer sterilization pouches are equipped with their own internal and external indicators printed on the pouch. Be sure to double check that both indicators are present before packaging in case of unannounced inventory changes due to backordered items or switching of manufacturers.
