Thealoz is a completely new alternative in the management of dry eyes. Rather than just supplementing the existing tears, Thealoz also works by protecting the cells of the cornea and conjunctiva and giving resistance to dryness. This makes it perfect for chronic dry eye sufferers and means that Thealoz is an ideal addition to your dry eye products because it works in a different way to anything else currently available.

Thealoz contains 3% trehalose, a unique natural disaccharide, which protects the cells of the cornea and conjunctiva. Studies have shown that Thealoz significantly improves TBUT (tear break up time) and signs of corneal damage (as measured by Fluorescein and Rose Bengal staining scores) in patients with moderate to severe dry eye within two weeks of use. The drops can be applied as often as necessary throughout the day.

Thealoz is presented as a sterile, preservative-free, isotonic, and pH neutral aqueous ophthalmic solution, in the ABAK system bottle and is contact lens compatible. These multidose bottles can be used for up to 8 weeks from opening but are no bigger than a single multi-dose unit.

Helps really dry eyes but I found it could sting a little occasionally.
Theoloz appears to be the best product for my dry eye condition, it prevents my dry eyes from deteriorating and becoming sore and red.
Was running out so came just in time
These seem to work ok for me in the day.
v satisfied with your range and prompt efficiency, thank you
I have tried other brands, however they seem not to be suitable for my dry eye problem. I can always rely on Thealoz, it isn't sticky and it doesn't cause any blurred vision after application.
The service is always swift and efficient and they use a reliable carrier.
The best dry eye drops I've tried.
Delivery always prompt and efficient
Thealoz helps my dry eye problem.
Very quick delivery
Prompt efficient service as always.
Met expectations
Same as for HYabak
After trying many products for severe dry eyes finally I have found a product with excellent benefits.
Very pleased with service and the low p&p rate. Will definitely use again.
Hoped for great things from this new product type but unfortunately it didn't work well for me. (severe dry eye and MGD). doesn't mean it won't work for you!
I like these drops because they can be instilled when necessary, therefore making them easy to use. After instillation there is a slight misting of the eyes but this clears very quickly. They are very soothing, and cooling, therefore relieving my very dry eyes, especially after driving, reading, and using the computer. Thank you Butterflies.
