New Preservative-free Combination of Trehalose, Sodium Hyaluronate and N-acetyl-aspartyl-glutamate (NAAGA) in Dry Eye

The goal of this prospective, non-randomized, non-comparative, monocentric PMCF study is to assess the performance of a new preservative-free combination of trehalose, sodium hyaluronate and NAAGA on DED at 6 months in 30 patients having dry eye disease.

The main questions it aims to answer are:

* To assess the performance and safety of T2769 at 3 months and 6 months. * To assess patient compliance to therapy. * To assess the occurrence of dry eye flares. Participants will be asked to use T2769 on a daily basis and complete a self-questionnaire throughout the study.
