Comparing Lipid Layer Thickness Measurements From Three Devices and Their Link to Dry Eye Severity

What this Trial Is About

Researchers are evaluating the measurements of ocular lipid layer thickness LLT taken by three commonly used clinical devices to compare their agreement and consistency. The study also aims to find which devices LLT measurements best correlate with established clinical indicators of dry eye disease severity. Participants with dry eye disease will have their lipid layer thickness measured using three different devices LipiView, Omnicad, and Bruder Ocular Surface Analyzer. These measurements will be taken during a single visit in a random order to ensure unbiased comparison. During the study visit, participants will undergo LLT measurement with all three devices. Researchers will analyze the measurements and compare them to clinical assessments of dry eye severity. The main outcome is the LLT measurement at baseline, alongside the correlation with clinical dry eye indicators. The study participation involves a single visit and does not include any treatment or long-term follow-up.
