The contribution of tear osmolarity measurement to ocular surface assessment in contact lens wearers

2012

Purpose: To determine whether tear osmolarity using the TearLabTM Osmolarity System contributes to the assessment of the ocular surface in contact lens (CL) wearers.Methods: Data were collected from 44 CL wearers (28 tolerant and 16 intolerant) and 34 healthy subjects. Every patient underwent a thorough ophthalmic examination and tear osmolarity test, conjunctival impression cytology and meibomian lipid sampling. Symptoms, break-up time (BUT), tear osmolarity, conjunctival expression of HLA-DR and meibomian fatty acid composition were evaluated.Results: Tear osmolarity was significantly higher in the controls compared to tolerant and intolerant CL wearers (p=0.0007).
