Design outcomes

Primary

MeasureTime frame
Evaluation of the subjective tolerance upon instillation (rate of patients experiencing symptoms of discomfort), graded as very good, good, bad or very bad, measured at baseline, 1 and 3 months

Secondary

MeasureTime frame
1. Assessment of each of the symptoms of the Glaucoma Symptom Scale [15] (Yes/ No): burning/smarting/stinging, tearing, dryness, itching, soreness/tiredness, feeling of something in the eye, blurry/dim vision, hard to see in daylight, hard to see in dark places and halos around the light (for those who report a given symptom, a bothersome scale will be used: very, somewhat, a little, not at all) 2. Slit lamp examination (examination of conjunctiva, cornea, iris, lens, anterior chamber), performed at baseline, 1 and 3 months 3. Tear-film-break-up-time-test (BUT-test; sec), performed at baseline, 1 and 3 months 4. Fluorescein staining of the cornea, performed at baseline, 1 and 3 months 5. Van Bijsterveld test (Lissamine green), performed at baseline, 1 and 3 months 6. IOP measured at 12 PM (+/- 30mn), measured at baseline, 1 and 3 months 7. Assessment of Visual acuity and visual field, measured at baseline (if no visual field performed during the previous 3 months) and at 3 months 8. Fundoscopy, performed at baseline, 1 and 3 months 9. Adverse events, reported at 1 and 3 months 10. Compliance, reported at 1 and 3 months
