Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in tear lipid layer thickness
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in the thickness of the tear lipid layer in microns measured using the EASYTEARView+ Dacryscope.
An increase in tear lipid layer thickness is considered a positive treatment effect
|
Measured at baseline, 1-month, and 3 months
|
|
Change in tear thinning rate
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in the rate of tear thinning in %/sec measured using the EASYTEARView+ Dacryscope.
A decrease in the rate of tear thinning is considered a positive treatment effect
|
Measured at baseline, 1-month, and 3 months

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in Meibomian gland function
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in the clinical grade of meibum expressed from the Meibomian glands using the Korb Meibomian Gland Evaluator.
Clinical grades assigned based on a 0-30 point scale, with 30 indicating copious, clear meibum and 0 indicating no meibum expressed (blocked orifices).
An increase in score indicates improved gland function.
|
Measured at baseline, 1-month, and 3 months
|
|
Change in tear production rate
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in the rate of tear production in µL/min, measured using the Schirmer Tear Test.
An increase in tear production is considered a positive treatment effect.
|
Measured at baseline, 1-month, and 3 months
|
|
Change in tear breakup time
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in non-invasive tear breakup time in seconds, measured using the Oculus Keratograph 5M.
An increase in tear breakup time is considered a positive treatment effect.
|
Measured at baseline, 1-month, and 3 months
|
|
Change in Ocular Comfort
Tidsramme: Measured at baseline, 1-month, and 3 months
|
Change from baseline in ocular discomfort, measured using the Ocular Surface Disease Index (OSDI) on a 0-100 scale.
A decrease in OSDI score is considered a positive treatment effect.
|
Measured at baseline, 1-month, and 3 months
