- use of contact lenses within 1 week before screening and throughout the study
- active ocular disease other than DED or any other acute or chronic disease which may interfere with the aims of the clinical trial
- history of severe allergies or multiple drug allergies unless it is judged as not relevant for the clinical trial by the investigator
- diagnosis of Corona Virus Disease (COVID-19) within the last 14 days prior to individual enrolment of the patient
- contact to persons in international risk areas for COVID-19 as defined by the Institute of Public Health of Serbia within the last 14 days prior to individual enrolment of the patient
- known direct contact with insufficient protection to persons with diagnosis of COVID-19 within the last 14 days prior to individual enrolment upon reporting of the patient
- history of or current drug or alcohol dependence
- participation in an investigational drug or device study ≤30 days before screening
- positive pregnancy test at screening examination
- pregnant or lactating women
- female patients who do not agree to apply highly effective contraceptive methods (highly effective contraceptive methods are defined in chapter 13.2.1)
- patients suspected or known not to follow instructions
- patients who are unable to understand the written and verbal instructions, in particular regarding the risks and inconveniences they will be exposed to during their participation in the clinical trial

Group Intervention Description Vizol S LIPID BALANCE Vizol S LIPID BALANCE eye drops topical administration of 1 drop of Vizol S LIPID BALANCE in each eye 4 times a day for 30 days ophthalmic saline eyedrops ophthalmic saline eye drops topical administration of 1 drop of ophthalmic saline eye drops matching Vizol S LIPID BALANCE in each eye 4 times a day for 30 days
- Primary Outcome Measures
Name Time Method Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 3 (day 30) baseline, week 2 follow-up and week 4 follow-up Tear film break-up time (TFBUT) will be assessed at each visit following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation.
Three measurements per eye will be performed and the mean value documented and used for evaluation.
- Secondary Outcome Measures
Name Time Method Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 2 (day 15) baseline and week 2 follow-up Tear film break-up time (TFBUT) will be assessed following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation.
Two measurements per eye will be performed and the mean value documented and used for evaluationMean change in OSDI score from Visit 1 (baseline) to Visit 3 (day 30) baseline, week 2 follow-up and week 4 follow-up Symptoms of DED will be assessed using the Ocular Surface Disease Index (OSDI) questionnaire at each visit.
The 12-item OSDI questionnaire scores range from 0 to 100, it contains 3 ocular symptom questions, 6 vision-related function questions, and 3 environmental trigger questions. Each question score ranges from 0 ("none of the time") to 4 ("all of the time"). The total score is calculated based on the following formula:
Total score: OSDI = (\[sum of scores for all questions answered\*100\]/\[total number of questions answered\*4\])percent (%) change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 2 (day 15) and from Visit 1 (baseline) to Visit 3 (day 30) baseline and week 2 follow-up; baseline and week 4 follow-up Tear film break-up time (TFBUT) will be assessed following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation.
Two measurements per eye will be performed and the mean value documented and used for evaluationMean change in ocular surface staining score (total corneal and total conjunctival staining score) from Visit 1 (baseline) to Visit 3 (day 30) baseline, week 2 follow-up and week 4 follow-up Ocular surface staining of five corneal regions and six conjunctival regions will be observed at each visit by slit-lamp examination after instillation of fluorescein respectively.
Surface staining will be scored as 0 (normal, no staining), 1 (mild, superficial stippling or macropunctate staining), 2 (moderate, macropunctate staining with some coalescent areas), or 3 (severe, numerous coalescent macropunctate areas or patches). Scores will be summed to yield total corneal and total conjunctival staining scores for each eye.Mean change in Meibomian gland expression from Visit 1 (baseline) to Visit 3 (day 30) baseline, week 2 follow-up and week 4 follow-up Meibomian gland expression will be observed by slit-lamp examination. Glands will be expressed from the temporal to the nasal aspect using a cotton-tipped applicator. Five glands in each area of the lower lid (nasal, central, temporal) will be examined.
Expressed meibum (across all glands) will be classified as follows: clear, easily expressed (grade 0), cloudy, mild pressure (grade 1), cloudy, \> moderate pressure (grade 2), meibum not expressed, with hard pressure (grade 3).
