- Infection control is concerned with two main areas. Firstly, transmission from person to person, and secondly, transmission via a contaminated object.
- You must ensure that a safe environment is provided to deliver care to your patients.
- You must follow appropriate infection controls, including hand hygiene.
- You should keep up-to-date with immunisations.
- You must use and dispose of sharps safely.
- You should be aware of situations of increased concern, including patients with transmissible infections.
- You should use routine infection control precautions, including decontaminating equipment that comes into contact with patients.
- You should know the measures to take in case of accident.
- You must dispose of waste safely.
- This Guidance does not change what you must do under the law.
- Infection control is concerned with two main areas. Firstly, transmission from person to person, and secondly, transmission via a contaminated object, such as an ophthalmic device or piece of equipment, or via contaminated contact lens solution bottles or multi-dose eye drops that have been used on another patient. In addition, there are environmental hazards that arise from your disposal of waste (refer to COVID-19 guidance).
Routes for transmission
- There are four main routes for transmission, these are:
- physical contact, which can spread:
- ophthalmic infections, such as bacterial and adenoviral conjunctivitis (refer to COVID-19 guidance)
- skin infections, for example staphylococcus, herpes simplex or fungi
- enteric infections, for example viral gastroenteritis
- airborne particles, including respiratory infections, for example tuberculosis:
- you are at a special risk of the transmission of airborne infection because of the proximity to the patient’s nose and mouth
- potentially infectious respiratory aerosols are generated when an individual sneezes, coughs or talks. Particles over 5 microns in diameter do not normally travel more than 1m but smaller particles can travel longer distances and remain airborne for longer
- contact with bodily fluids:
- you are at extremely low risk of transmitting blood borne viruses, such as human immunodeficiency virus (HIV) and hepatitis B and C, in optometric practice
- tears can contain infectious agents (including these viruses, and others that are much more contagious, such as adenovirus) which may be transmitted to yourself or to other patients if your hands are not properly cleaned after the clinical examination
- all spillages of blood and body fluids should be cleaned up immediately using a product that contains a detergent and disinfectant. Do not use mops for this. Use disposable paper towels and dispose of them as clinical waste.173
- use of sharps: the main risk of transmission is associated with invasive procedures in which injury, for example needlestick, could result in blood from the infected individual entering open tissues of another person. If you suffer an injury from a sharp which may be contaminated, you should:
- gently encourage the wound to bleed, if possible whilst holding it under running water
- wash the wound using running water and plenty of soap
- dry the wound and cover it with a waterproof plaster or dressing
- seek urgent medical advice
- report the injury to your employer.174 175
You should not suck the wound or scrub it while you are washing it.
- physical contact, which can spread:

Hand hygiene (refer to COVID-19 guidance)
- You must decontaminate your hands regularly and thoroughly to prevent the spread of infection, see paragraphs B31-B33.177 You can reduce the risk of transmitting infections such as methicillin-resistant Staphylococcus aureus (MRSA) or Clostridium difficile (C.diff) if you use fastidious hand hygiene.
- There are a number of organisms present in healthy skin: some are resident organisms (skin commensals) and are mostly harmless, although some are known to cause mild eye infections. You can reduce the number of skin commensals left on your skin by washing with an antiseptic detergent preparation, instead of soap and water.
- Other transient organisms can be deposited on the skin, including certain gram-negative bacteria which could lead to more serious corneal infections. You can remove most of these transient organisms by thoroughly washing with liquid soap and water (use warm water where available).
- You must decontaminate your hands, as appropriate:
- before every episode of direct patient contact or care
- after every episode of direct patient contact or care
- after any exposure to body fluids (including tears)
- after any other activity or contact with a patient’s surroundings that could potentially result in hands becoming contaminated
- after removal of gloves.
- You can use an antibacterial handrub between seeing patients during a clinic session. Alcohol is not a cleaning agent, so you should perform a proper handwash with soap and water at the beginning and completion of the clinic session, as well as after exposure to body fluids. Alternatively, you can wash your hands between patients.
- You should also decontaminate your hands:
- before (and after) contact lens insertion or removal
- after going to the toilet
- when hands are visibly dirty
- before (and after) contact with ocular surfaces and adnexae
- before (and after, if necessary) administering medication, for example eye drops
- after any possible microbial contamination, e.g. contact with body fluids, wounds, or clinical waste.
- You should use the following handwashing technique for most procedures you perform in the clinical setting:
- wet hands under running water (use warm water where available)
- dispense liquid soap or antiseptic into cupped hand (bar soap should not be used)
- rub hands vigorously and thoroughly for at least 15 seconds without adding more water
- ensure all surfaces of the hands are covered
- rinse hands thoroughly under running water (use warm water where available)
- dry hands with a disposable paper towel. You should not use non-disposable towels.
- Handwashing with soap and water is effective in removing most transient microorganisms and is usually all you need to prevent infection. In clinical areas, you should:
- use liquid soap in disposable containers or containers that are washed and dried before refilling
- never top up the containers.
- Antiseptic agents are effective in reducing both transient and resident microorganisms. Chlorhexidine (4%) preparations have a residual effect against transient organisms influencing the survival time on hand surfaces.179 You should use an antiseptic agent:
- before and after direct contact with patients in clinical settings, where there is an outbreak of antimicrobial resistant organisms (e.g. residential or nursing homes)
- where there is heavy microbial contamination
- before performing invasive procedures or minor operations.
- Antibacterial (alcohol-based) handrubs rapidly destroy microorganisms on the skin's surface. However, they are not a cleaning agent and you should not use them if hands are visibly dirty or contaminated with blood, bodily fluids or other potentially infectious agents. They are especially useful in situations where handwashing and drying facilities are inadequate e.g. domiciliary visits, or between patient contacts.
- You should not use alcohol handrubs as a substitute for handwashing with soap and water, when these are available. You are strongly advised to wash your hands at the start and finish of a session. Alcohol handrubs are not effective against Clostridium difficile spores or norovirus (a cause of viral gastroenteritis), so you should use liquid soap and water in situations where there is potential for the spread of these organisms.
- The standard for efficacy of hygienic handrubs uses a reference of 60% isopropyl alcohol. However, to be effective against staphylococci, including MRSA, handrubs must contain 70% of either ethyl or isopropyl alcohol.
- Using an unperfumed alcohol-based handrub prior to contact lens insertion has been shown to have a negligible effect on ocular comfort, redness and lens wettability. You should ensure that the handrub has been allowed to dry on the hands as instructed by manufacturers (often 15 seconds).
Maintain the integrity of your skin
- To maintain the integrity of your skin, you should:
- cover cuts and abrasions to skin with waterproof dressings (preferably coloured)
- dry your skin properly with paper hand towels after washing
- use hand cream as appropriate; you should not share jars of hand cream with others.
Keep up to date with immunisation
Minimise the risk of airborne infection
- You should minimise the risk of airborne infection by:180
- covering your nose and mouth and using a tissue whilst coughing or sneezing
- disposing of used tissues in the nearest appropriate receptacle as soon as possible181
- performing hand hygiene after coughing or sneezing
- not working in clinical practice if you have an acute upper respiratory tract infection, such as the common cold
- avoiding touching your mouth, eyes and nose unless you have performed hand hygiene.
Protective clothing (refer to COVID-19 guidance)
- Wear protective clothing (refer to COVID-19 guidance):
- to protect against direct contact with body fluid
- while handling and cleaning decontaminated equipment.
- You do not have to use a mask, unless there is a serious risk of respiratory infection or there is a public health requirement to wear one, such as during a pandemic. If you do need to use a face mask you should follow the relevant national or local public health guidance to ensure you are using the correct mask with the appropriate level of protection182 (refer to COVID-19 guidance).
Gloves (refer to COVID-19 guidance)
- You should wear gloves where you consider there is a risk from:
- invasive procedures
- contact with:
- non-intact skin
- mucous membranes
- exposure to:
- bodily fluids, including tears
- sharp or contaminated instruments
- other contaminated material, for example dressings.
- You should consider the following factors when deciding to wear gloves (refer to COVID-19 guidance):
- whether the patient has an overt infection, such as ulcerative blepharitis or acute viral or bacterial conjunctivitis
- the degree of contact with bodily fluids or infected tissue
- the consequences of infection.
- You do not have to wear gloves to (refer to COVID-19 guidance):
- carry out a normal eye examination
- perform minor procedures where there is no likelihood of cross-inoculation with bodily fluids
- fit contact lenses.
- You should practise thorough hand hygiene before wearing, and after removing, gloves, as they may not provide complete protection.
- You can use non-sterile disposable examination gloves. However, if you undertake a procedure which requires a sterile environment, you must use sterile surgical gloves. You must not use polythene gloves for clinical interventions. If you choose to use latex gloves you should be aware that these might cause allergic reactions such as asthma in sensitised individuals183 184 (refer to COVID-19 guidance).
Appropriate sharps disposal
- If you need to use sharps, you should use and dispose of them safely by: 186
- using equipment with safety devices
- using safe handling and disposal procedures.

- High-risk groups include patients with MRSA, C.difficile, tuberculosis (within the first two weeks of treatment), or pandemic influenza (where there is no vaccine available) and Staphylococcus aureus, which have caused particular concern in recent times.
- Staphylococcus aureus is a bacterium that can reside on the skin, or can be found in the nose. About one third of healthy individuals carry S. aureus. MRSA is a less common variant of S. aureus which may be resistant to many antibiotics making it more difficult to treat than normal strains of the bacterium. MRSA is a problem in many hospitals. Although the risk of serious infection with MRSA is lower in the community, it is increasingly seen in community health care units, such as nursing homes. MRSA does not cross intact skin.
- There is little risk of infection for healthy clinical staff; however, infection control is important to avoid transmission to vulnerable people.
MRSA in the community
- MRSA detected in the community may be the result of:
- patients discharged from hospital with MRSA
- nursing home residents who have acquired MRSA
- MRSA transmitted to non-hospitalised patients, or other individuals, from MRSA patients
- MRSA arising naturally in the community.
- If you examine a patient with a known transmissible infection, you should:
- increase the effectiveness of your hand hygiene by:
- keeping nails short, clean and free of nail varnish, and by avoiding artificial nails
- avoiding wearing jewellery, especially rings with ridges or stones
- avoiding wearing wristwatches
- keep in mind NHS policy on clinician attire by:
- wearing short sleeves or rolling up long sleeves
- not wearing a tie.
- increase the effectiveness of your hand hygiene by:
- Transmission via an inert agent can be from a contaminated object, such as an ophthalmic device or piece of equipment, or via contaminated contact lens solution bottles or multi-dose eye drops that have been used on another patient (refer to COVID-19 guidance).
- The agents that may harbour infection are:
- contact lenses, contact lens cases and other paraphernalia
- ophthalmic devices such as:
- tonometer heads
- diagnostic lenses that come into contact with the ocular surface, such as: gonioscopes, fundus lenses, three-mirror lenses and lenses used in conjunction with laser therapy
- the environment: bacteria may contaminate flat surfaces if they become airborne. Bacteria that are shed into the environment may survive for long periods in dust. Flat surfaces act as reservoirs for S. aureus, including MRSA, and contamination will transfer easily to hands that touch them. Contamination on hands and/or gloves may then be transferred by contact with equipment, switches, phones, computer keyboards, door handles, light switches etc.
- You should use the following routine infection control precautions (refer to COVID-19 guidance):
188 National Institute for Health and Care Excellence (2017) Healthcare-associated infections: prevention and control in primary and community care. Clinical Guideline 139 [Accessed 1 Dec 2020]
- You should decontaminate equipment that comes into contact with patients, including (refer to COVID-19 guidance):
- trial frames
- chin and forehead rests
- refractor heads
- handheld occluders
- tonometer heads
- gonioscopes and other diagnostic lenses
- contact lenses.
- You should decontaminate equipment in all situations where you or your patients are at risk of any known transmissible infection, including nursing homes, schools and workplaces.
- There are three levels of decontamination. You should use the one that is most appropriate for the item being decontaminated. The three levels are:
- cleaning to remove organic or inorganic debris. This may be done with detergents or ultrasonic cleaning
- disinfecting to reduce viable microorganisms with heat or chemicals
- sterilising to kill or remove all microorganisms, including spores. This is not normally required in optometric practice.
- Not all equipment needs to be sterile before being used and you should:
- clean equipment which does not come into close contact with mucous membranes or sterile body areas, e.g. trial frames and refractor heads
- clean surfaces in the consulting room, unless contaminated with body fluids, see d below
- disinfect equipment which comes into close contact with intact mucous membranes
- 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)
- sterilise equipment introduced into a sterile body area or in contact with a break in the skin or mucous membrane.
- Agents recommended for cleaning and disinfection procedures (refer to COVID-19 guidance):
|Agent||Preparation||Examples of use|
|Liquid soap||as supplied||handwash|
|Chlorhexidine gluconate 4% skin cleanser||500 ml bottles with pump dispenser eg Hibiscrub||antiseptic handwash|
|Chlorhexidine 5% in 70% isopropyl alcohol 189||
500 ml bottles with pump dispenser eg Hibisol
|antiseptic hand disinfectant for use before aseptic procedures or after handling contaminated materials|
|Alcohol-based hand sanitizer||as supplied, usually in bottles with pump dispenser eg Purell (contains 63% ethyl alcohol)||routine handrub|
|Detergent||general purpose detergent or detergent impregnated wipes eg Cutan multisurface wipes||leaning of hard surfaces|
|Isopropyl alcohol 70%
eg mediswabs or wipes
|disinfection of hard surfaces, chin rests etc.
(not suitable for use with medical devices that come into contact with the surface of the eye)
|Hypochlorite solution 0.1%
(1,000 ppm available chlorine)
|available from pharmacies eg Milton or own brand sterilising solution (dilute to concentration required)
under normal usage, these agents are disinfectants, and not sterilants
(ensure that items are thoroughly rinsed in sterile saline or distilled water after using hypochlorite)
|Hypochlorite solution 1%
(10,000 ppm available
|disinfection of body fluid spills and decontamination of trial contact lenses, diagnostic contact lenses, tonometer heads and other devices that come into contact with the surface of the eye (ensure that items are thoroughly rinsed in sterile saline or distilled water after using hypochlorite)|
- Items must be clean before progressing to disinfection or sterilisation (refer to COVID-19 guidance).
- There is a remote theoretical risk, identified by the Department of Health (DH), of transmitting prion proteins, which are associated with transmissible spongiform encephalopathies (TSEs) and are implicated in Creutzfeldt-Jakob Disease (CJD) and variant CJD (vCJD), through re-useable ophthalmic devices and trial contact lenses. However, there is no evidence that this has occurred,190 and this risk has been questioned.191 The anterior eye has been designated as low risk.
- You should follow the advice of your local infection control team if available. If this is not available:
- You should use single patient use lenses and devices that contact the surface of the eye where practicable.
- You should not re-use a lens or device that is intended by the manufacturer for single use.
- When single use lenses and devices are not practicable, you should:
- balance the benefits that patients receive from contact lenses and ophthalmic devices against the transmission of disease
- apply appropriate disinfection procedures. These should include the use of sodium hypochlorite solution where possible, see paragraph B63.
Definitions of contact lenses
- You should note these definitions of contact lenses:
- trial contact lens: a lens that is used to assess fitting following which it is either disposed of by the clinician or dispensed to the patient. The majority of contact lens patients are currently fitted with single patient use lenses of various types
- special complex lens: a lens used by the clinician to assess performance of the design on the eye. This may be necessary where there is disease or abnormality of the lid, cornea or ocular surface. These lenses may be re-used.
- The above definitions can apply to the following categories of lenses:
- hydrogel lenses
- silicone hydrogel lenses
- hybrid lenses
- rigid lenses, including:
- scleral shells
- ocular prostheses.
- Special complex lenses may be of any type. If you use these lenses you must carry out appropriate disinfection.
Definitions of ophthalmic devices
- An ophthalmic device is any instrument which comes into contact with the ocular surface, including:
- contact pachymeter
- other lens to aid diagnosis of disease.
- Where it is practicable, you should use single use devices, such as disposable tonometer heads or tips.
- Some devices are not able to withstand certain forms of disinfection. In these cases, you should use your professional judgement, bearing in mind that undetected disease may have sight- or life-threatening consequences.
How to disinfect equipment
- The following advice reduces the potential risk of iatrogenic transmission of CJD/vCJD via contact devices.
- You should not use alcohol wipes alone to disinfect contact devices as they are ineffective against many organisms, and may fix prion proteins to the surface of the instrument.
- Prion proteins adhere strongly to materials including smooth surfaces. You should ensure that the device is thoroughly cleaned to remove adhered debris as the potential for the transmission of cellular and proteinaceous debris via tonometer prisms has been demonstrated.192, 193
- You should not use agents or procedures capable of binding proteins to surfaces e.g. isopropyl alcohol, glutaraldehyde or autoclaving, unless you decontaminate devices first, following the process outlined in paragraphs B80-B81.
- You should use 1% sodium hypochlorite solution to disinfect equipment. This concentration is:
- appropriate for inactivating infectious agents such as bacteria and viruses
- less harmful to the eye than stronger concentrations, should it accidentally come into contact with it.
- You need the following equipment for disinfecting of contact lenses or ophthalmic devices:
- water for irrigation BP, or sterile normal saline
- cleaning solution, such as liquid soap or detergent
- sodium hypochlorite solution 1% (10,000 ppm of available chlorine).
- You should follow this process to disinfect contact lenses or an ophthalmic device (refer to COVID-19 guidance):
|Step||ACDP TSE WG, 2011 recommendation164||Notes|
|Timing||immediately after use||immediately disinfect the item, and if this is not possible, keep it in a container of water for irrigation BP or sterile normal saline, until it can be disinfected.|
|Do not dry||do not allow to dry|
|Rinse||in water for irrigation BP/sterile normal saline for at least 30 sec|
|Clean||rubbing with liquid soap or detergent||thoroughly clean the item (including by rubbing) to remove cellular debris and adherent protein|
|Disinfect||using sodium hypochlorite
1% (10,000 ppm of available chlorine) for 10 min
disinfect it by using sodium hypochlorite
|Rinse||in water for irrigation BP/sterile normal saline for at least 10 min with 3 changes of water/saline||thoroughly rinse off the sodium hypochlorite, which is toxic to the eye, before re-use|
|Dry||shake off excess, dry with tissue, re-use immediately or store dry||return the item to its dedicated case, if it has one|
|Further steps||if necessary, since hypochlorite is not effective against all spores or cysts||follow with conventional disinfection|

- Chlorine can be toxic to the eye, but if you follow the disinfection guidelines correctly, sodium hypochlorite solution will not come into contact with a patient’s eye. However, if this does occur, you should follow this process:
- irrigate the affected eye immediately with copious quantities of sterile normal saline solution or water
- check the ocular surface for epithelial damage using fluorescein
- examine the anterior segment for inflammation
- check intraocular pressure
- if there are no clinically significant signs, advise the patient to return to the practice if they experience any problems with their eyes. Otherwise you should re-examine them at the normal interval
- if there are clinically significant signs, you should re-examine the patient the following day or refer them to the Hospital Eye Service, as appropriate
- record any adverse incident centrally, in your practice’s system or in the practice Accident Book
- if you feel it is appropriate, report the incident to the National Reporting and Learning System This is anonymous and helps us to learn lessons from adverse incidents.194

- You should carefully maintain all contact lens care products and medicines used during examination, and discard them when they reach their expiry date.
- You should:
- be aware that multi-dose containers can be a source of infection
- be aware that varying levels of contamination exist in plastic bottles containing contact lens solutions
- note on the bottle when it was opened and when it should be discarded according to manufacturer’s guidelines.
- You should:
- keep the dropper tip free from contamination
- replace the lid on the container immediately after use, as all solutions are susceptible to contamination while the lid is off
- dispose of solutions immediately if you suspect contamination.
High-risk groups (refer to COVID-19 guidance)
- Patient groups that have been identified as being at greater than normal risk of developing transmissible spongiform encephalopathies (TSE) include:
- patients with a family history of CJD or other prion disease
- recipients of pituitary derived hormones such as human growth hormone or gonadotrophins
- patients who have had surgery on the brain or spinal cord
- patients who have received more than 50 units of blood or have received blood or blood components on more than 20 occasions, since 1980.
Examining a patient in a high-risk group
- Before carrying out any procedure that might involve the re-use of a contact lens or ophthalmic device you should, as far as possible, question the patient to establish if they fall into any of the above high-risk groups. If the patient is in a high-risk group, you must only use items intended for single patient use. If this is not possible you should consider referring the patient to the Hospital Eye Service.
- If you use a re-usable item in an emergency with a patient in one of the above high-risk groups, you should discard it immediately after use.
- If you examine a patient with a known transmissible infection, you should:
- You must take all reasonable steps to deal appropriately with controlled, clinical and offensive waste, including both non-hazardous and hazardous waste196 197 198 199 (refer to COVID-19 guidance)
- Clinical waste means waste from a healthcare activity¸ and waste of a similar nature from a non-healthcare activity, that:200
- contains viable microorganisms or their toxins which are known or reliably believed to cause disease in humans or other living organisms
- contains, or is contaminated with, a medicine that contains a biologically active pharmaceutical agent
- is a sharp, or a body fluid or other biological material (including human and animal tissue) containing, or contaminated with, a dangerous substance within the meaning of Council Directive 67/548/EEC on the approximation of laws, regulations and administrative provisions relating to the classification, packaging and labelling of dangerous substances.
- Offensive waste means waste that:201
- is not clinical waste
