  • 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

Treatment and study plan

Vizol S LIPID BALANCE eye drops

Drug

1 drop 4 times a day

Other names: Test

ophthalmic saline eye drops

Drug

1 drop 4 times a day

Other names: Placebo

Primary outcomes

  1. Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 3 (day 30)

    Time frame: 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 outcomes

  1. Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 2 (day 15)

    Time frame: 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 evaluation

  2. 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)

    Time frame: 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 evaluation

  3. Mean change in ocular surface staining score (total corneal and total conjunctival staining score) from Visit 1 (baseline) to Visit 3 (day 30)

    Time frame: 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.

  4. Mean change in OSDI score from Visit 1 (baseline) to Visit 3 (day 30)

    Time frame: 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])

  5. Mean change in Meibomian gland expression from Visit 1 (baseline) to Visit 3 (day 30)

    Time frame: 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).

Other outcomes

  1. The presence of Adverse Event/ /Serious Adverse Event (AE/ /SAE) throughout the investigation period

    Time frame: baseline, week 2 follow-up and week 4 follow-up

    The patients will be asked to report any Pre-Treatment Sign and Symptom/Adverse Events (PTSS/AEs) spontaneously.

  2. BCVA

    Time frame: baseline, week 2 follow-up and week 4 follow-up

    Best corrected visual acuity (BCVA) will be assessed at each visit. BCVA assessment will be at 4 meters using an ETDRS chart (The Early Treatment Diabetic Retinopathy Study Group). Results will be calculated as logMAR scores.

  3. Frequency of ocular signs

    Time frame: baseline, week 2 follow-up and week 4 follow-up

    Ocular signs will be assessed by slit-lamp examination at all study visits. The following signs will be assessed:

    • active inflammation or significant structural change or discharge (eyelids and conjunctiva);
    • active inflammation or active structural change, including focal scarring and fine deposition (cornea);
    • active inflammation (iris and anterior chamber);
    • level of lens opacity, pseudophakia, or aphakia (lens, with an emphasis on the visual axis)
