Now available in pharmacy. Cationorm® is different from eye drops you might have tried before. It uses ionic technology to attract its positively charged solution to the negatively charged surface of the eye, locking in hydration for longer.
Its deep-acting clinically proven formula targets all three layers of the eye and helps to:
- Restore moisture and maintain hydration
- Protect the surface of the eye
- Relieve discomfort and irritation
Cationorm® is for people looking for:
- Something different to a sodium hyaluronate-based artificial tear.
- Long-lasting relief from stinging, itching, burning eyes or foreign body sensation.
Kind to even sensitive eyes, Cationorm® is preservative free and is suitable for everyday use and for contact lens wearers.
If you are unsure about your diagnosis, please speak to your doctor or pharmacist. Always read the label.

The dispenser is awful. Badly designed. Drops drip down outside of bottle. Have to use four times daily. Very frustrating.so much waste. Worst dispenser have ever had to use. Hylo Forte bottle is superior design. Am very disappointed.been using since April 2025. Get back to the drawing board please | Research and Development Dept MUST change this awful dispenser. Having read reviews am really surprised that you have not taken on board that which patients have complained of ! Useless designed bottle.

The drops are very good but getting them out is a total pain. You have to squeeze really hard and you either still don’t get anything or you get a small flood. I went online to see if I was the only one who was struggling with this and clearly not! Reviews mention it over and over again. It’s a badly designed dropper. Change the bottle please

The formulation is great. The best eye drops I’ve ever used so far. This comes from someone who deals with alot of eye problems like dryness, styes etc. But! What’s with the dropper design it’s like a toddler designed it. Super hard to use; messy and will end up wasting product.

I’ve tried several dry eye products- Cationorm are expensive, but sounded good, so I tried them. I don’t find them any better than other cheaper products I’ve used, and it is very difficult to squeeze the drops out of the bottle. I either get nothing out, or drops trickling down my face. I should think anybody with arthritic hands would find them impossible to use.
I am therefore going to go back to using the cheaper, user-friendly drops.

Good drops, awful packaging, hard to squeeze when you have half bottle left. I end up wasting drops everytime. For the price I pay for these drops someone should reconsider packaging.

This works brilliantly for my dry eyes. I use it 2x/day,morning and evening. Its so soothing and works well before and after insertion of my contact lenses. Having tried all the other products on the market,this is by far the best

Hi Paula, thank you for your lovely review. Have a lovely day!
Fabulous. I got these on a free trial as I work in an eye infirmary. I get extremely dry eyes and even worse on Nightshift. These relieved the soreness and pain immediately.

Hi Tracy!
Thank you for the great feedback, we’re so glad to hear this.
Have a great day!
Having had dry eye for over 55 years ive tried them all to no avail ! But these drops have the worst spout / tip of them all so small and stubby you very nearly poke your eye out,whoever in this day and age designed that? Also you will need to buy two bottles because one bottle will just stream down your face as it misses your eye completely so hard to squeeze and just get one drop out! Awfull small bottle and very expensive! Minor relief for two minutes then back to normal pain!

These drops are so comforting for my dry eye condition. I am really impressed by their efficacy and after trying most products on the market in the last 10 yrs I’m very happy to continue using them. I have also reduced the number of drops necessary each day which is far more convenient for me.
Jill, Wolverhampton
I have used numerous products ,including preservative free prescription drops for ten years. These Cationorm eye drops are far and away more effective than any others. I am really delighted at how my severe dry eye problems have been reduced. Well worth the money.
George, Birmingham
Have just finished my first bottle. Much more relief than with any of the previous prescription drops. Very impressed,
George, Birmingham
Honestly super happy I have tried so many many eye drops, sprays and creams and and nothing worked that great. Now that I am using your product my eyes feel better and look better after a few days very happy with Cationorm I really recommend people should try it.
J, Northern Ireland
These drops feel really nourishing for the eyes. First application I was aware of seeing all milky for a few seconds after application but after using for a day this effect disappeared and my eyes started to feel a lot more hydrated and comfortable. Very good product. Would definitely buy again.

An excellent and effective product. I have a condition called blepharitis. These drops are the best and MOST effective that I have found. I recommended them wholeheartedly
Deanne, Ely Cambs
To be honest these drops did not make any difference and was a waste of time. They did not improve or relieve my condition so was disappointed that did not get results what you said these drops could do
Veronica, Essex
I have spent quite a lot of money on eye drops in the past, but nothing beats this one. No watery eyes make up stays on. Brilliant eye drops even though a little expensive well worth the money
Patricia, Manchester
I have very dry eyes and corneal erosion. These eye drops are very soothing and they don’t affect my vision, so no blurring after they’ve been applied. I use them 4 times a day.

I bought these because the marketing led me to believe they would improve my dry eye symptoms . After using for 10 days my dry eyes have not shown any improvement whatsoever.. these eye drops are like all other eye drops I have tried ..comforting for a few minutes then .., you still have dry eyes
Jones, Cheshire West
I use eye drops for glacoma which give me a lot of discomfort. I have tried various drops for dry eyes and associated problems but nothing worked. My consultant gave me Cationorm to try and I have to say it gives me far more relief than anything else I have tried. I shall be ordering more shortly.
