These patients received fixed combination therapy with eye drops containing arabinogalactan, hyaluronic acid, and trehalose at various dosing schedules. The data for this study were collected from April 2022 to June 2023. Patients underwent evaluation at baseline (T0) and after a follow-up period of two–three months (T1) using a patient-reported questionnaire.Results: In 96 adult patients (71 women and 25 men) with dry eye due to various conditions, the results indicated a 98% positive response to therapy. This response included improvements in vision (13%), comfort (39%), redness (13%), itching (16%), photophobia (4%), and tearing (14%). Additionally, 61% of the patients experienced 1– 2 hours of comfort following instillation.Conclusion: This real-life post-marketing study demonstrated clinical improvement of signs and symptoms in patients with dry eye disease using a new artificial tear medical device based on arabinogalactan, hyaluronic acid, and trehalose.Keywords: dry eye, real-world study, arabinogalactan, hyaluronic acid, trehalose, post-marketing study
