Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The investigational test cream is "Lauricidin" (Epi-shield) and the control cream "Petroleum jelly" will be used in both safety and efficacy phases.
In the safety phase, randomised contralateral double masking was employed. Therefore, either the test or control cream was randomly applied once only to the skin surrounding the eyelid area of participant's right eye (Day 1) or left eye (Day 2) at the baseline visit, by a clinic team member who was not involved in any further clinical assessment .
In the efficacy phase, randomised parallel study design will be employed. Therefore, one group of participants will receive the test cream and the other group will receive the control cream randomly and they will apply the creams on both eyes . In this phase, participants will be instructed to apply the cream to the skin surrounding the eyelid area, twice a day for 6 weeks. Participants will be asked at each visit how thy have been applying the cream and the frequency at which they have been applying the cream. Participants will be monitored after 1 week, 3 weeks and 6 weeks after the baseline visit at the Clinical Research and Trials Centre, Brien Holden Vision Institute, UNSW.
Lauricidin Registered Trademark - Main ingredients: (glycerol monolaurate) 1%, Propylene glycol monocaprylat 1%, Lactic Acid 2%. Other ingredients: Petrolatum, Lanolin, Beeswax, C12-15 alkyl benzoate, cetyl alcohol).

Outcomes
Primary outcome [1] 296880 0
Safety phase: change in eye redness from baseline post the topical application of cream will be assessed through the use of a slit lamp under diffuse illumination using ×10 to ×16 magnification. Clinical grades of eye redness will be recorded on a scale of 1 to 4 in steps of 0.5.
Timepoint [1] 296880 0
Baseline, 3 hrs after application, 6 hrs after application
Primary outcome [2] 304800 0
Safety phase: Change in corneal staining from baseline post the topical application of cream. Following the careful addition of sodium fluorescein (1 mg, Fluorets; Chauvin Pharmaceuticals Ltd., UK), the cornea will be observed with cobalt blue illumination using a Wratten 12 filter in front of the slit-lamp biomicroscope under ×10 to ×16 magnification. Corneal staining type will be graded for the cornea as a whole using a 0 to 4 scale 0.5 steps, while extent and depth of staining will be graded in 1 steps.

Primary outcome [3] 304801 0
Efficacy phase: Change in dry eye symptoms score measured using Ocular Surface Disease Index (OSDI) questionnaire
Timepoint [3] 304801 0
Baseline, 1 week, 3 weeks, 6 weeks, 9 weeks
Secondary outcome [1] 319598 0
Safety phase: change in ocular symptoms from baseline post the topical application of cream, Secondary outcome was assessed by subjective rating on a numerical ocular discomfort scale (1-10) with 1 being most severe discomfort score and 10 being the highest comfort score. A worsening in ocular comfort score from baseline by more than 2 points was considered 'unsafe'.

Efficacy phase: Change in fluorescein tear break-up-time (TBUT) as assessed with a slitlamp, sodium fluorescein and a stopwatch.

Baseline, 1 week, 3 weeks, 6 weeks, 9 weeks
Secondary outcome [3] 343229 0
A swab of the inferior lid margin using a sterile disposable q-tip. The swab sample will then immediately be stored in a sterile vial for later analysis. Lid swabs from individuals will be cultured, and the bacteria will be isolated and identified by gram-staining. Isolated bacteria will then be grown in liquid media, and the supernatant will be extracted and used to quantify the lipase levels through colorimetric assay.

Safety/efficacy
Statistical methods / analysis
Safety phase: There will be about ten subjects in this phase. One eye of participants will be included for assessing the safety of the test and the other for the control cream in randomly manner.
Efficacy phase: a sample size of approximately 27 (+ 3) participants in each treatment group and a total sample of 54 (+6) participants will have at least 80% power at the 5% level of significance to detect the difference in the OSDI score from baseline to the end of the trial. Presuming there is a change in the dry eye category, every 10-point score on the OSDI scale changes the dry eye classification i.e. normal (<12.5), mild (13-22), moderate (23-32) and severe (33-100).
