Théa Duo Gtt Opht

Thealoz Duo contains 3% trehalose and 0.15% sodium hyaluronate in a preservative-free formulation. Trehalose protects the epithelial cells on the ocular surface and improves their resistance to daily stress in dry environments and tear film changes in dry eye. It has a very high water retention capacity with 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 conditions. Clinical studies have shown that a single drop of Thealoz Duo improves tear film thickness for at least 4 hours (6 times longer than sodium hyaluronate alone). 8 In one study, 62% of patients receiving Thealoz Duo were symptom-free after 84 days, with significant improvements in visual disturbances, stinging, and itching. Thealoz Duo is a hypotonic formulation (low osmolarity) that specifically treats tear film hyperosmolarity in chronic dry eye to effectively relieve symptoms. The uniquely designed, patented, preservative-free bottle allows for easy application. Products containing preservatives can cause ocular surface toxicity leading to inflammation and cell death. Using preservative-free eye drops supports ocular surface health.
