Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - BlephEx
Other interventions - Lid Hygenix

Experimental: Microblepharon Exfoliation - This treatment is provided using BlephEx tool from Optimed Pty Ltd.

Experimental: Eyelid cleansing using Lid Hygenix - Foam-based hypoallergenic cleanser used as a control treatment in this study.


Treatment: Devices: BlephEx
BlephEx is an instrument that contains a hand piece used to spin a medical grade micro-sponge along the edge of eyelids and lashes that helps in removing scurf and debris from eyelids and helps in exfoliating the lids. A new micro-sponge will be used for every subject to avoid cross-contamination. This procedure lasts for 6-8 mins.

Other interventions: Lid Hygenix
Foam-based hypoallergenic cleanser used to clean eyelid margins is used as a control intervention for the study.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
All participants will be given a unique study identification code. Data will be de-identified at the time of collection such that only patient initials and a study identification number will be used to identify the data for each patient. Any data included in reports, publications or presented at meetings will be provided in the form of group responses or study identity numbers, such that the participants cannot be identified. Personal and health information (either identifiable or potentially identifiable) about individuals will not be disclosed to any external parties without the individual's consent unless required by law. The unique study identification code can be broken by the research team if required (re-identifiable).
