Thealoz Duo is Thea’s most advanced preservative-free combination of sodium hyaluronate and trehalose for moderate to severe dry eyes, in a hypotonic formulation that can be used with contact lenses.


Thealoz Duo contains trehalose 3% and sodium hyaluronate 0.15% in a preservative-free formulation - products containing preservatives can cause ocular surface toxicity, leading to inflammation and cell death. Using preservative-free eye drops supports the health of the ocular surface.
Trehalose protects the epithelial cells on the ocular surface, improving their resistance to daily stress of dry environments and tear film changes in a dry eye; it has very high water retention capabilities with both bioprotection and osmoprotection properties.
Sodium hyaluronate adds moisture by retaining water to hydrate and lubricate the surface of the eye
Thealoz Duo is indicated for moderate to severe dry eye disease.
Clinical studies have shown that a single drop of Thealoz Duo improves the thickness of the tear film for at least 4 hours (6 times longer than sodium hyaluronate alone).
In one study, 62% of patients receiving Thealoz Duo were symptom free after 84 days, with significant improvements in blurred vision, stinging and itching.
Thealoz Duo is a hypotonic formulation (low osmolarity), which means it particularly addresses the hyperosmolarity of the tear film in chronic dry eye to effectively soothe symptoms.
