Dry Eye Disease

Brief summary

The goal of this interventional investigation is to compare BUFY02 with TRB02 in the treatment of patients with dry eye disease. The main questions it aims to answer are: * Is BUFY02 non-inferior to TRB02 in terms of signs of DED? * Is BUFY02 non-inferior to TRB02 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 BUFY02 to TRB02 to see if both study treatments provide similar effects on signs and symptoms of the disease, together with comparable safety.
