Principles of cleaning, sterilisation and disinfection

B55
You should decontaminate equipment that regularly comes into contact with patients, including:
  1. trial frames
  2. chin and forehead rests
  3. refractor heads
  4. handheld occluders
  5. rulers
  6. tonometer heads
  7. gonioscopes and other diagnostic lenses, and
  8. contact lenses.
B56
You should decontaminate equipment in all situations where you or your patients are at risk of any known transmissible infection, including settings such as:
  1. nursing homes
  2. schools, or
  3. workplaces.
B57
There are three levels of decontamination. You should use the one that is most appropriate for the item being decontaminated. The three levels are:
  1. cleaning to remove organic or inorganic debris. This may be done with detergents or ultrasonic cleaning
  2. disinfecting to reduce viable microorganisms with heat or chemicals, or
  3. sterilising to kill or remove all microorganisms, including spores. This is not normally required in optometric practice.
B58
You must clean the items first.
B59
Not all equipment needs to be sterile before being used and you should:
  1. clean equipment which does not come into close contact with mucous membranes or sterile body areas, e.g. trial frames and refractor heads
  2. clean surfaces in the consulting room, unless contaminated with body fluids, see d below
  3. disinfect equipment which comes into close contact with intact mucous membranes
  4. disinfect surfaces in the consulting room if contaminated with body fluids, using a chlorine-releasing disinfectant such as sodium hypochlorite 1% (10,000 ppm of available chlorine), and
  5. sterilise equipment introduced into a sterile body area or in contact with a break in the skin or mucous membrane.
B60
You should have access to a hand basin in, or near, the consulting room.
