Outcome results
Change From Baseline (Pre-application) in Non-Invasive Tear Film Break-Up Time (NIBUT)
Non-invasive break-up time is the time in seconds between eye opening and the appearance of the first visible break in the lipid layer of the pre-corneal tear film measured by the investigator using the Tearscope Plus in conjunction with a Topcon SL-D7 slit lamp biomicroscope and high-resolution digital video recording. Change from Baseline to T0 (immediately), T15, T30, T60, T120, T180, T240, T300, T360 mins after application was reported. A negative change from Baseline (Pre-application) indicates improvement.

Change From Pre-application in Exposed Area (EA)
Exposed Area is defined as the percentage of the observed area not covered by the tear film at the time of the blink hence exposed to the atmosphere measured by the investigator using a Tear scope Plus in conjunction with a Topcon SL-D7 slit lamp biomicroscope and high-resolution digital video recording. Change from Baseline to T0 (immediately), T15, T30, T60, T120, T180, T240, T300, T360 mins after application was reported.
Time frame: Pre-application (Day 0) to time (T) 0 (immediately), 15, 30, 60, 120, 180, 240, 300 and 360 minutes on Day 0 after application
Population: All participants who met the eligibility criteria, adhered to the protocol, and successfully completed the full study assessment were included in the per-protocol analysis.

Change From Pre-application in Protective Index (PI)
The Protected Index (PI) corresponds to the percentage of the corneal surface that is not exposed to the atmosphere (i.e. fully covered by the tear film) over the full interblink period measured by the investigator using a Tear scope Plus in conjunction with a Topcon SL-D7 slit lamp biomicroscope and high-resolution digital video recording. Change from Baseline to T0 (immediately), T15, T30, T60, T120, T180, T240, T300, T360 mins after application was reported.
