Thea Thealoz Duo, 10Ml, Dry Eye Treatment, Preservative-Free, 3% Trehalose, 0.15% Sodium Hyaluronate

Thealoz Duo is a preservative-free eye drop that contains trehalose 3% and sodium hyaluronate 0.15%. Trehalose helps protect the epithelial cells on the ocular surface, improving their resistance to dry environments and tear film changes in dry eye. It also has high water retention capabilities with both bioprotection and osmoregulation 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 can improve the thickness of the tear film for at least 4 hours, and in one study, 62% of patients receiving Thealoz Duo were symptom-free after 84 days, with significant improvements in blurred vision, stinging, and itching. The product has a hypotonic formulation, which helps address the hyperosmolarity of the tear film in chronic dry eye.
