Plain English Summary
Background and study aims
Dry eye or meibomian gland dysfunction (MGD) is a complex condition for which numerous management products have been developed to deal with the many causes of the condition. Dry eye has significant impact on quality of life and is a burden. 0.18% emulsion CE-marked eyedrop manufactured by Horus Pharma has the potential to provide dry eye relief for moderate to severe dry eye based on the composition of the eyedrop.
The purpose of this study is to evaluate eyedrop performance and its beneficial effect in people with moderate to severe dry eye problems after one month of daily use. There are two phases of the study. The first phase is to determine the effect of a single instillation of the eyedrop over a two-hour period. The second phase is to determine the eyedrop effect after repeated daily use over a one-month duration.
Who can participate?
Adults who are between 18 to 75 years old, healthy, currently not wearing contact lenses or using the study eyedrop and have moderate to severe dry eye signs and symptoms.
What does the study involve?
Participants will be given eye drops to use instead of their usual eye drops for one month.
What are the possible benefits and risks of participating?
Participants may not directly benefit from taking part in this study but will have the opportunity to try a different eyedrop to manage their dry eye condition and will also receive a free examination of the front part of their eyes and free supply of the study product during their participation in the study. Due to the nature and short duration of the study, the risks of participating are considered minimal.

0.18% HA emulsion Characterisation of Clinical Performance and Acceptance
Phase 1 of this study is an exploratory study hence no hypothesis will be tested
Phase 2: After one-month use of eyedrop the overall subjective ocular comfort visual analog scale (VAS) score rating and ocular surface status will improve for the overall study population, irrespective of the dry eye etiology

Dry eye/Meibomian Glands Dysfunction (MGD)
Emulsion eyedrop containing 0.18% sodium hyaluronate, phospholipids, triglycerides and alpha lipoic targets all three layers of the tear film, as well as being hypoosmolar hence addressing the inflammatory component of dry eye.
This study will characterise the short and long-term clinical performance and acceptance of the emulsion eyedrop.
For the short term (Phase 1), the effect of a single instillation of the eyedrop before and over a two-hour period post instillation will be quantified for tear film characteristics and subjective acceptance (comfort and vision).
For the long-term (Phase 2) the effect of the repeated use of the eyedrop over a one month use period on overall subjective comfort improvement before and after use will be measured. Forty symptomatic dry eye participants will be enrolled. There will be three study visits (for phase 1 and 2) and two study visits (for phase 2 only) over a 45-day period.
Participants will need to stop using habitual eyedrops two days prior to the first study visit and during the study period. The potential participants will attend the clinic for Visit 1 to obtain informed consent and evaluate suitability to take part in the investigation. The participants will be asked to complete a series of questionnaires to capture demographics, medical & ocular history, medications, ocular symptomatology (Ocular Surface Dryness Index - OSDI and Visual Analog Scale -VAS for eye comfort, vision and eye sensations experienced), vision measurement with spectacle correction, eye examination using a microscope and a beam of light (slit lamp). If meeting the investigation’s inclusion and exclusion criteria, participants will be enrolled, baseline measurements will be performed: visual acuity, non-invasive tear film digital videos recording, tear film collection, measurement of tear film evaporation, digital eye photos and conjunctival impression.
For those in both Phase 1 and 2, the study visits are described below.
At the end of the first study visit, the next visit will be scheduled 2-5 days later.
At Visit 2 (Phase 1 test/Phase 2 dispensing visit), the study staff will place one drop of the study eyedrop into each eye. Evaluations will be performed prior to the eyedrop instillation (pre), post eyedrop instillation at multiple time points over 2-hour period. The study eyedrop will be dispensed for the participants to take home and the eyedrop will be used every day. A short secure remote electronic survey will be completed every 4 days, like the questionnaires at the clinic.
At Visit 3 (35 ±5 Days after Visit 2), the study visit will follow the same routine as Visit 1. At the end of the visit, participants will be discharged from the study.
If in Phase 2 only, the study visits are described below.
At the end of the first study visit, the study eyedrop will be dispensed to take home and the participants will need to use the study eyedrop every day. Participants will then be scheduled to return for Visit 2 about a month later (35 ±5 Days after Visit 2). A short secure remote electronic survey will be completed every 4 days, like the questionnaires at the clinic.
At Visit 2, the study visit will follow the same routine as Visit 1, involving completion of a series of questionnaires, examination of ther eyes using a microscope and a beam of light (slit lamp), and vision measurements. The same specialized measurements will be repeated and at the end of the visit, participants will be discharged from the study.
