Reusable instruments for everyday clinical procedures
Clinical tools designed for repeated use, practical handling and reliable performance in modern optometric practice.
At SOS, we supply reusable ophthalmic instruments that support the procedures clinicians carry out every day, from meibomian gland expression to ocular surface and acute eye care work.
These are not just products on a shelf. They are tools chosen with clinical use, cleaning, handling and replacement in mind.
Built for repeated clinical use
Reusable instruments can offer a practical alternative to a single-use-only approach, especially where a procedure is carried out regularly in practice.
They allow clinicians to work with familiar tools, maintain consistency across procedures and manage stock more effectively.
Used correctly, cleaned appropriately and replaced at the right point, reusable instruments can become part of a safe, efficient clinical workflow.
Why choose reusable tools?
Practical value for clinical practice
Reusable instruments are especially useful where clinicians need reliable tools for procedures they perform frequently.
They can help practices:
- reduce the need to reorder the same tool for every procedure
- improve familiarity and confidence through repeated use
- reduce avoidable waste where reusable options are appropriate
- manage costs over a practical replacement cycle
- support consistent procedure-based workflows
The right choice will always depend on the instrument, the procedure, manufacturer guidance and the practice’s own infection control policy.
Designed to be used, cared for and replaced
Reusable does not mean indefinite.
Many SOS reusable instruments are designed for a practical working life of around three months, depending on usage, cleaning process, handling and storage.
This gives practices a clear and manageable replacement rhythm while still gaining the benefits of using a tool repeatedly during its lifespan.
Reusable instruments should be inspected regularly and replaced if they become damaged, worn, difficult to clean or no longer perform as expected.
Cleaning, disinfection and clinical judgement
Reusable instruments need appropriate care between uses.
Cleaning, disinfection and sterilisation are not the same thing. The College of Optometrists defines cleaning as removing debris, disinfection as reducing viable microorganisms and sterilisation as killing or removing all microorganisms, including spores. It also notes that sterilisation is not normally required in optometric practice.
Some ophthalmic devices that come into contact with the ocular surface require specific disinfection processes. Professional guidance also makes clear that single-use lenses or devices should not be reused.
For this reason, every practice should follow:
- manufacturer instructions
- professional guidance
- local infection control policy
- appropriate clinical judgement
SOS provides product information and clinical expertise to help practitioners make informed decisions, but each practice remains responsible for using and decontaminating instruments correctly.
A more considered approach to clinical purchasing
In healthcare, single-use items are sometimes essential. Patient safety must always come first.
However, where reusable options are clinically appropriate, they may help practices reduce unnecessary waste and make purchasing more efficient.
Research into NHS surgical products has found that single-use items can make a significant contribution to product-related carbon impact, with one study of five common operations finding that single-use items accounted for 68% of product carbon contributions.
This does not mean every product should be reusable. It means practices benefit from making considered choices: single-use where necessary, reusable where appropriate.
Reusable instruments for procedure-led care
SOS reusable instruments are selected around real clinical procedures, including:
- meibomian gland expression
- dry eye and ocular surface management
- acute eye care support
- foreign body removal workflows
- clinical examination and treatment support
This helps clinicians choose tools based on what they need to do in practice, not just what appears in a product catalogue.

Reusable ophthalmic instruments: clinical FAQs
Practical answers to common questions about reusable ophthalmic instruments, including lifespan, cleaning, disinfection, storage, replacement and what not to use.
This guidance is designed to support good decision-making in practice. Always follow manufacturer instructions, professional guidance and your own infection control policy.
How long do reusable ophthalmic instruments last?
Many SOS reusable instruments have a practical working life of around 3-6 months, depending on how often they are used, how they are handled, how they are cleaned and how they are stored.
Reusable instruments should be checked regularly and replaced sooner if they become damaged, worn, difficult to clean or no longer perform as expected.
Are reusable instruments safe to use?
Yes, when they are suitable for the procedure, cleaned and disinfected correctly, stored appropriately and replaced when needed.
The correct approach depends on the instrument, the procedure, manufacturer instructions, professional guidance and the practice’s own infection control policy.
Are reusable tools better than disposable tools?
It depends on the instrument and the procedure.
Single-use items are important where they are required for safety, practicality or manufacturer compliance. Reusable tools can be a better option where repeated use is clinically appropriate, cost-effective and supported by the correct cleaning, disinfection, storage and replacement process.
The practical principle is: single-use where necessary, reusable where appropriate.
When should a reusable instrument be replaced?
A reusable instrument should be replaced at the end of its recommended working life, or sooner if there are signs of wear, damage, corrosion, reduced performance or difficulty cleaning it properly.
Reusable should never mean “use indefinitely”. A clear replacement cycle helps protect performance, hygiene and patient safety.
Do reusable instruments need to be sterilised?
Not always.
Cleaning, disinfection and sterilisation are different processes. The College of Optometrists explains that cleaning removes debris, disinfection reduces viable microorganisms and sterilisation kills or removes all microorganisms, including spores. It also notes that sterilisation is not normally required in optometric practice.
The correct process depends on how the instrument is used and whether it comes into contact with the ocular surface, mucous membranes, broken skin or sterile body areas.
What is the difference between cleaning, disinfection and sterilisation?
Cleaning removes visible and invisible contamination such as debris, residue and organic material.
Disinfection reduces viable microorganisms to a safer level.
Sterilisation kills or removes all microorganisms, including spores.
Items should be clean before progressing to disinfection or sterilisation.
How often should reusable instruments be disinfected?
Reusable instruments should be cleaned and disinfected between uses, according to the manufacturer’s instructions, professional guidance and the practice’s infection control policy.
Instruments that come into contact with the ocular surface or mucous membranes need particular care, because the risk profile is different from non-contact surfaces such as chin rests or trial frames.
If an instrument has been disinfected but not used for a while, does it need to be disinfected again?
There is not a single universal time limit that applies to every reusable ophthalmic instrument.
If an instrument has been correctly cleaned, disinfected and stored, it may remain suitable for use according to the practice’s infection control process. However, if there is any doubt about storage, handling, contamination or whether the item has remained clean, it should be cleaned and disinfected again before use.
The safest answer is always to follow the manufacturer’s instructions, professional guidance and local infection control policy.
Can I use Milton to disinfect metal ophthalmic instruments?
No.
The College of Optometrists lists hypochlorite solutions, including Milton or own-brand sterilising solution, as disinfectants under normal usage, not sterilants. It is also important to note that Milton’s own product information says it cannot be used on metal and that it may be corrosive to metals.
Can I use alcohol wipes or an alcohol-based steriliser?
Alcohol-based products are not a shortcut for disinfecting reusable ophthalmic instruments.
The College of Optometrists lists 70% isopropyl alcohol as suitable for some hard surfaces, such as chin rests, but states that it is not suitable for medical devices that come into contact with the surface of the eye.
The College also advises that alcohol wipes alone should not be used to disinfect contact devices, because they are ineffective against many organisms and may fix prion proteins to the surface of the instrument.
So, while alcohol-based products may have a place for some hard surfaces, they should not be relied on for instruments that touch the ocular surface unless the manufacturer’s instructions and professional guidance specifically support that use.
What should I avoid using on reusable ophthalmic instruments?
Avoid assuming that a product is suitable simply because it says “sterilising”, “antibacterial” or “medical grade”.
Reusable ophthalmic instruments should only be cleaned and disinfected using methods that are suitable for the item, the material, the procedure and the level of patient contact involved.
In particular, DO NOT USE:
- alcohol wipes or alcohol-based products on contact devices
- Milton or hypochlorite solutions on metal instruments.
- any product used at the wrong dilution
- any process that skips cleaning before disinfection
- any disinfectant that is not properly rinsed where rinsing is required
- any method that conflicts with manufacturer instructions
Can single-use ophthalmic items be reused?
No. If an item is marked as single use, it should not be reused.
The College of Optometrists states that practitioners should not reuse a lens or device that is intended by the manufacturer for single use.
Do reusable instruments save money?
They can do.
Reusable instruments may reduce the need to purchase a new item for every procedure, especially where a practice carries out the same procedure regularly. The saving depends on the cost of the instrument, how often it is used, the cleaning process and the replacement cycle.
For many practices, the benefit is not only cost. It is also consistency, familiarity and having the right instrument available when it is needed.
Are reusable instruments more sustainable?
They can be part of a more considered approach to clinical purchasing, but this should not be overstated.
Single-use items are sometimes essential. Patient safety must always come first. However, where reusable tools are clinically appropriate, they may help reduce avoidable waste and unnecessary repeat purchasing.
When should a reusable instrument be replaced?
A reusable instrument should be replaced at the end of its recommended working life, or sooner if there are signs of wear, damage, corrosion, reduced performance or difficulty cleaning it properly.
Reusable should never mean “use indefinitely”. A clear replacement cycle helps protect performance, hygiene and patient safety.
Who is responsible for deciding the correct cleaning or disinfection process?
Each practice is responsible for using, cleaning, disinfecting, storing and replacing instruments correctly.
SOS provides product information and clinical expertise to support good decision-making, but practices should always follow manufacturer instructions, professional guidance, local infection control policy and appropriate clinical judgement.
Practical tools, supported by clinical knowledge
Reusable instruments are not just about reducing repeat purchases.
They are about giving clinicians reliable tools for the procedures they carry out regularly, while supporting safe handling, appropriate care and responsible replacement.
