Efficacy and Safety of BUFY01 Versus SVS20 in the Treatment of Dry Eye Disease

The goal of this interventional investigation is to compare BUFY01 with SVS20 in the treatment of patients with dry eye disease. The main questions it aims to answer are:

* Is BUFY01 non-inferior to SVS20 in terms of signs of DED? * Is BUFY01 non-inferior to SVS20 in terms of symptoms of DED?

Participants will be asked to:

* Visit the trial site at 4 different timepoints * Use the allocated study treatment everyday until the end of the study (during 3 months) * Be examined by the investigator * Complete several questionnaires * Return unused study treatment.

Researchers will compare BUFY01 to SVS20 to see if both study treatments provide similar effects on signs and symptoms of the disease, together with comparable safety.
