Currently there are many resources and guidelines revolving around general infection control, and infection control specific to the COVID-19 pandemic.

Below listed are some that are useful not just for optometrists, for but patients and family alike! Hover over the bolded areas for links! If not, they are all listed below.

Clinical and Experimental Optometry: Infection Control Guidelines for Optometrists 2016
A paper written to give guidelines about infection control for optometrists. It highlights main points such as:

Elements necessary for infection
  1.  Direct or indirect contact (inc blood borne)
  2. Droplets that can be spread from coughing, sneezing, talking but also via hands
  3. Airborne small particle aerosols are created during talking, breathing, coughing, sneezing
  4. Other modes of transmission eg: contaminated water, medication, devices, equipment etc
Standard precautions relevant to the optometric practice which contain:
  1. hand hygiene
  2.  use of personal protective equipment
  3. safe use and disposal of sharps
  4. routine environmental cleaning
  5. reprocessing of reusable medical equipment and instruments
  6. respiratory hygiene and cough etiquette
  7. aseptic non‐touch technique and
  8. waste management.
To ensure to be up to date with immunisations for:
  1. Hepatitis B
  2. Influenza (yearly)
  3.  pertussis (includes diphtheria, tetanus, whooping cough)
  4. varicella (chicken pox if not immune)
  5. MMR (measles, mumps, rubella if not immune)
Further discussions about hand hygiene and products to use, such as:
  1. plain soap
  2. alcohol-based antiseptics
  3. chlorhexidine

Personal protective equipment such as:
  1. Powder free surgical gloves especially with the possibilty of contamination with blood or body fluid, or in contact with high risk patients. 
  2. Face shields for procedures where there could be a potential for airborne infection.

Contact lenses
  1. Multi-use contact lenses should be cleaned and rinsed before and after use

Tonometer probes
  1. Although common practice is to use an alcohol swab to clean the prism and allow it to air dry, there have been various studies looking at how to better remove viral or bacterial load off the tonometer prisms
  2. the American Academy of Ophthalmology mentioned the that the CDC recommended tonometry trips to be wiped clean, disinfected for 5-10 mins by being submerged in either 5,000 ppm chlorine or 70% ethyl alcohol, rinsed then air dried
  3. Adenovirus (eg: EKC) can be removed with alcohol, iodophor or hydrogen peroxide wipes or a five minute soak with these agents or bleach.
  4. If concerned about transmission of infection, use a disposable tonometer tip/probe instead
disinfecting gonioscopy lenses also follow tonometry guidelines. However, for any instrument disinfection, it is also recommended to look at manufacturer's instructions/guidelines.

Daily consulting room hygiene, such as:
  1. cleaning benches, sink, computer keyboard and mouse, any electronic devices (eg: mobiles, tablets)
  2. covering equipment

Patient Education, such as:
  1. how to use prescribed eyedrops, and when to dispose of them
  2. how to maintain contact lens hygiene (with CL, CL case, etc)
  3. Eye make up (not sharing make up, to throw away make up if contaminated or passed expiry date)
Extra precautions during a pandemic (specifically H1N1), such as:
  1. isolation of those who exhibit symptoms
  2. use of surgical masks (P2/N95) by both the infected person and healthcare workers to reduce risk of transmission of infection
  3. frequent hand washing 
  4. proper cough and sneeze etiquette
  5. supply of tissues and immediate disposals of tissue 
  6. rescheduling for non-urgent appointments
  7. protection for staff members too

Hand Hygiene Australia
Hand Hygiene Australia contains evidence-based resources and strategies with educating health care workers how to maintain effective health hygiene to reduce or prevent transmission of infections from patient to patient, or patient to yourself.
Not only does it discuss about hand hygiene techniques (refer to this link); about washing your hands in a specific way for 30 secs), but it also discusses about different types of hand rubs!
They also contain a module that is highly recommended to do!

Optometry Australia
OA has released an abundant amount of information regarding infection control
Infection Control Guidelines and Advice: COVID-19 specific information
https://www.optometry.org.au/practice-professional-support/coronavirus-covid-19-what-optometrists-need-to-know/covid-19-clinical-advice/infection-control-guidelines-and-advice/
OA has highlight guidelines not just for optometrists, but also for patients, staff and family. They also contain a free 30 minute online training module for health workers regarding infection prevention and control.
For optometrists specifically, they have a “five moments of hand hygiene”; which highlights when you should wash your hands according to HHA.
  1.  Before touching a patient
  2.  Before a procedure
  3. After a procedure or body fluid exposure risk
  4. After touching a patient
  5. After touching a patient’s surroundings

Australia Department of Health is also contain a free 30minute online training module for health workers regarding infection prevention and control.

Similarly, WHO also has a 60 min online training module revolving around infection control too.
