Lamelleye vs Comparator for the Treatment of Dry Eye Disease
- Conditions
- Dry Eye Syndromes
- Interventions
- Device: Lamelleye Dry Eye DropsDevice: Optive Plus
- Registration Number
- NCT03052140
- Lead Sponsor
- Glasgow Caledonian University
- Brief Summary
Single-blind, randomised, single centre, 2-way crossover study to collect post-market clinical follow-up data on the CE-marked Lamelleye dry eye drops medical device.
- Detailed Description
The study is a 2-way crossover design comprising 2 treatments: the CE-marked Lamelleye dry eye drops, and a CE-marked comparator product. All Participants will be allocated to a treatment group in a random order.
This study design allows observations to be made between the treatments at both an intra- and inter-patient level regarding relationships between the patients' disease specific quality of life, symptoms and adverse events.

Group Intervention Description Treatment A, followed by Treatment B Lamelleye Dry Eye Drops Treatment group that will receive Treatment A for 14 days, followed by Treatment B for 14 days. There will be a minimum 7 day washout between Treatments. Lamelleye Dry Eye Drops and Optive Plus will be administered to all subjects in this arm. Treatments will be self-administered at least 3 times a day.

- Primary Outcome Measures
Name Time Method Non-invasive tear break-up time (outcome used to power study) 14 days (analysed for each Treatment period) Measure of time taken from blink to breakup of tear film
- Secondary Outcome Measures
Name Time Method Ocular Surface Disease Index (OSDI) 14 days (analysed for each Treatment period) 12-item questionnaire designed to assess the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning
Symptom Assessment in Dry Eye (SANDE) 14 days (analysed for each Treatment period) Two questions which each use a horizontal visual analogue technique to quantify patient symptomatology of dryness and/or irritation
Evaporimetry 14 days (analysed for each Treatment period) Measure of the rate of evaporation of the tear film from the surface of the eye.
Interferometry 14 days (analysed for each Treatment period) Tear film lipid layer interferometry is a test to study the structure and quality of the lipid layer in the tear film.
Osmolarity 14 days (analysed for each Treatment period) Tear osmolarity is a test to determine the solute concentration of the tear film.
Corneal and Conjunctival Staining 14 days (analysed for each Treatment period) Corneal and conjunctival damage due to dry eye can be measured by staining the surface of the eye with fluorescein and examining under a lamp with a cobalt blue filter
