The Story
What Are Hycosan Extra Eye Drops and How Do They Help Dry Eyes?
Dry, gritty, or uncomfortable eyes are something millions of people in the UK deal with every day. Whether it's screen fatigue, environmental triggers, or an underlying condition, the discomfort can be genuinely disruptive. Hycosan extra eye drops offer a preservative-free solution containing 0.2% sodium hyaluronate — a concentration designed specifically for moderate to severe dry eye symptoms. At just £9.99, they're an accessible option for anyone looking for reliable, daily eye lubrication without the need for a prescription. If you're exploring your options, our eye care collection includes a range of products to suit different needs.
Dry eye disease is more common than many people realise. The NHS notes that it affects people of all ages, though it becomes increasingly prevalent with age and is more common in women. Symptoms can range from mild irritation to significant visual disturbance, and finding the right lubricating drop makes a real difference to daily comfort.
How Do Hycosan Extra Eye Drops Work to Relieve Dryness?
The active ingredient in these drops is sodium hyaluronate, a substance that occurs naturally in the body — including in the fluid that surrounds the eye. It works by forming a stable, viscous film over the ocular surface, mimicking the aqueous layer of the natural tear film. This helps to:
- Lubricate the surface of the eye and reduce friction during blinking
- Stabilise the tear film and slow evaporation of natural tears
- Support healing of the ocular surface epithelium in cases of mild damage from dryness
- Provide sustained relief without the need for frequent reapplication
Because the drops are preservative-free, they're particularly well-suited to people who use eye drops frequently throughout the day. Preservatives in some eye drops can cause irritation with repeated use, so the preservative-free formulation here is a meaningful advantage for long-term users.
Who Should Consider Using Hycosan Extra Eye Drops?
These drops are suitable for adults experiencing moderate to severe dry eye symptoms. They're especially useful if standard lubricating drops haven't provided enough relief. You might benefit from them if you:
- Spend long hours in front of screens and experience digital eye strain
- Live or work in air-conditioned or heated environments that dry out the eyes
- Wear contact lenses and suffer from associated dryness (remove lenses before use)
- Have been diagnosed with dry eye disease or keratoconjunctivitis sicca
- Are post-operative following laser eye surgery and need ocular surface support
They are not recommended for children unless specifically advised by a healthcare professional. Always speak to your pharmacist or GP if you're unsure whether these drops are right for your situation.
How Do Hycosan Extra Eye Drops Compare to Other Dry Eye Drops?
| Feature | Hycosan Extra Eye Drops | Hycosan (Standard) |
|---|---|---|
| Sodium hyaluronate concentration | 0.2% | 0.1% |
| Preservative-free | Yes | Yes |
| Suitable for | Moderate to severe dry eye | Mild dry eye |
| Contact lens compatible (after removal) | Yes | Yes |
How Should Hycosan Extra Eye Drops Be Stored and Are They Clinically Suitable for Long-Term Use?
Hycosan extra eye drops use a patented COMOD (Continuous Mono Dose) delivery system, which allows the bottle to dispense individual drops without introducing air or contaminants into the solution. This means the drops remain sterile throughout use without requiring preservatives — a genuine benefit for anyone using them regularly over weeks or months. The bottle should be stored below 25°C and discarded six months after first opening, regardless of remaining volume.
Long-term use is generally considered safe for most adults. However, if your symptoms worsen, change in character, or don't improve after a few weeks of regular use, it's worth seeking advice from an optometrist or GP. Persistent dry eye can sometimes indicate an underlying condition that warrants further investigation. You'll find a broader range of supportive products in our eye care collection if you need additional options alongside your drops.
This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Hycosan Extra Eye Drops
What Are Hycosan Extra Eye Drops and What Are They Used For?
Hycosan Extra Eye Drops are a sterile, preservative-free ocular lubricant containing 0.2% sodium hyaluronate. They are used to relieve the symptoms of moderate to severe dry eye syndrome — a condition where the eyes do not produce enough tears, or where the tears evaporate too quickly. Common symptoms include a burning or stinging sensation, grittiness, redness, and intermittent blurred vision. The NHS describes dry eye as a very common condition, particularly in older adults and those who spend extended time looking at screens.
These drops are classified as a CE-marked medical device rather than a licensed medicine, which means they do not require a prescription and can be purchased over the counter. They are intended for use in adults and are not a treatment for eye infections, allergies, or other ocular conditions — if you're unsure what's causing your eye discomfort, always seek professional advice first.
What Do You Need to Know Before Using Hycosan Extra Eye Drops?
Before using these drops, it's important to be aware of the following contraindications and precautions:
- Do not use if you are allergic to sodium hyaluronate or any other component of the formulation
- Remove soft contact lenses before instilling the drops; wait at least 15 minutes before reinserting
- Do not use if the bottle seal is broken before first use
- Not recommended for use in children unless directed by a healthcare professional
- If you have an eye infection, eye injury, or have recently had eye surgery, consult your doctor before use
- Discard the bottle 6 months after opening, even if product remains
Regarding drug interactions, sodium hyaluronate eye drops are not known to interact with systemic medicines. However, if you are using other eye drops or eye ointments, you should:
- Wait at least 5 minutes between instilling different eye drops
- Apply eye ointments last if using alongside drops
- Inform your optometrist or GP of all eye preparations you are currently using
How Should You Use Hycosan Extra Eye Drops Correctly?
Using these drops correctly ensures you get the most benefit and reduce the risk of contamination. Follow these steps each time:
- Wash your hands thoroughly with soap and water before handling the bottle
- Remove soft contact lenses if you wear them
- Tilt your head back slightly and look upward
- Gently pull down your lower eyelid to create a small pocket
- Hold the bottle tip close to your eye without touching it, and squeeze gently to release one drop
- Close your eye gently and blink a few times to spread the drop evenly
- Repeat in the other eye if needed
- Replace the cap securely after use
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Moderate to severe dry eye | Adults | 1 drop per affected eye | 3–5 times daily, or as directed |
| Post-operative ocular surface support | Adults (under professional guidance) | 1 drop per affected eye | As directed by clinician |
What Are the Possible Side Effects of Hycosan Extra Eye Drops?
Hycosan Extra Eye Drops are generally very well tolerated. Side effects are uncommon, but as with any ocular preparation, some people may experience mild reactions. If you're managing multiple health concerns alongside dry eye, our allergy and hay fever range may also be relevant, as allergic eye symptoms can sometimes overlap with dry eye.
Common side effects (may affect a small number of users):
- Temporary blurred vision immediately after instillation — this usually clears within a few minutes
- Mild stinging or burning sensation upon application
- A brief feeling of eye irritation or discomfort
Less common side effects:
- Redness of the eye (conjunctival hyperaemia)
- Watering or increased tear production shortly after use
- Eyelid irritation in sensitive individuals
Stop using the drops and seek medical advice if you experience significant pain, sudden changes in vision, or signs of an allergic reaction such as swelling around the eye or severe redness.
How Should You Store Hycosan Extra Eye Drops?
- Store below 25°C in a dry place, away from direct sunlight
- Do not refrigerate after opening
- Keep the bottle tightly closed when not in use
- Discard 6 months after first opening — write the opening date on the bottle
- Keep out of the reach and sight of children
- Do not use after the expiry date printed on the bottle

Frequently Asked Questions
Where can I buy Hycosan Extra Eye Drops online in the UK?
You can buy Hycosan Extra Eye Drops directly from Cured Pharmacy for £9.99, with no prescription required. They are available as an over-the-counter product and can be ordered online for convenient home delivery. Browse our full eye care collection for additional dry eye and ocular health products.
How do Hycosan Extra Eye Drops work in the eye?
Hycosan Extra Eye Drops contain 0.2% sodium hyaluronate, a naturally occurring molecule with strong water-retaining properties. When instilled into the eye, it forms a stable, lubricating film over the ocular surface that mimics the aqueous layer of the natural tear film. This reduces friction during blinking, stabilises the tear film, and provides sustained relief from dryness and irritation.
How do I use Hycosan Extra Eye Drops step by step?
Wash your hands first, then tilt your head back and gently pull down your lower eyelid to create a small pocket. Squeeze one drop from the bottle into the pocket without touching the tip to your eye, then close your eye and blink gently to distribute the drop. Repeat in the other eye if needed, and replace the cap securely after use.
How many times a day should I use Hycosan Extra Eye Drops?
The standard recommendation is one drop per affected eye, used three to five times daily. You can adjust frequency based on the severity of your symptoms, but always follow the guidance on the product label or as directed by your optometrist or pharmacist. Do not use more frequently than necessary without professional advice.
What are the side effects of Hycosan Extra Eye Drops?
Side effects are uncommon and usually mild. The most frequently reported effects include temporary blurred vision immediately after instillation, a brief stinging or burning sensation, and mild eye irritation. These typically resolve within a few minutes; if they persist or worsen, stop using the drops and consult a pharmacist or GP.
Can I use Hycosan Extra Eye Drops with contact lenses?
You should always remove soft contact lenses before applying Hycosan Extra Eye Drops and wait at least 15 minutes before reinserting them. This is because the drops may affect the material of soft lenses if applied while wearing them. Hard or rigid gas-permeable lenses should also be removed prior to instillation.
Who is eligible to use Hycosan Extra Eye Drops?
These drops are suitable for adults experiencing moderate to severe dry eye symptoms, including those caused by screen use, environmental factors, contact lens wear, or underlying dry eye disease. They are not recommended for children unless specifically advised by a healthcare professional. People with known hypersensitivity to sodium hyaluronate should not use this product.
What happens if I miss a dose of Hycosan Extra Eye Drops?
Because these drops are used as needed for symptom relief rather than on a strict dosing schedule, missing a single application is not a clinical concern. Simply use the drops when you next experience dryness or discomfort. Do not double up on drops to compensate for a missed application.
What is the difference between Hycosan and Hycosan Extra?
The key difference is the concentration of sodium hyaluronate: standard Hycosan contains 0.1% and is designed for mild dry eye, while Hycosan Extra contains 0.2% and is formulated for moderate to severe symptoms. Both products are preservative-free and use the same COMOD delivery system. If standard drops haven't provided enough relief, Hycosan Extra is the logical next step.
How long can I use Hycosan Extra Eye Drops for?
Hycosan Extra Eye Drops can be used long-term for chronic dry eye conditions, as sodium hyaluronate is well tolerated with extended use. The bottle must be discarded six months after first opening, regardless of how much product remains. If your symptoms have not improved after several weeks of regular use, consult your optometrist or GP for further assessment.
Are Hycosan Extra Eye Drops preservative-free?
Yes, Hycosan Extra Eye Drops are completely preservative-free. The COMOD (Continuous Mono Dose) delivery system keeps the solution sterile without the need for preservatives, making it suitable for people who are sensitive to preservatives or who need to use eye drops multiple times a day. This is a significant advantage over many other lubricating drops on the market.
Can I use Hycosan Extra Eye Drops if I have had laser eye surgery?
Dry eye is a common side effect following laser eye surgery such as LASIK or LASEK, and lubricating drops are frequently recommended as part of post-operative care. However, you should always follow the specific guidance given by your surgeon or eye care team regarding which drops to use and when. Speak to your clinician before starting any new eye preparation after surgery.
What are the alternatives to Hycosan Extra Eye Drops?
Alternatives include other sodium hyaluronate-based drops such as Hylo-Forte (also 0.2% sodium hyaluronate) and carmellose sodium drops such as Optive. The right choice depends on your symptom severity, sensitivity to ingredients, and whether you wear contact lenses. Explore our eye care range to compare available options.
Is there any research supporting the use of sodium hyaluronate eye drops for dry eye?
Yes, sodium hyaluronate is one of the most widely studied ocular lubricants and is recommended in clinical guidelines for the management of dry eye disease. Multiple published studies have demonstrated its effectiveness in improving tear film stability, reducing ocular surface damage, and relieving patient-reported symptoms. The NHS also recognises lubricating eye drops as a first-line treatment for dry eye.
How should I store Hycosan Extra Eye Drops to keep them effective?
Store the bottle below 25°C in a dry place, away from direct sunlight and out of reach of children. Do not refrigerate the bottle after opening, and always keep the cap tightly closed between uses. Write the date of first opening on the bottle and discard it six months later, even if product remains, to ensure sterility and efficacy.
