Contact lens discomfort in silicone hydrogel lens (SCL) wearers was associated with higher ratios of lipid fatty acid degradation on the lenses and reduced tear film stability, according to a study.
The analysis included 38 eyes from 38 participants, all of whom wore frequent-replacement silicone hydrogel lenses (Comfilcon A). Tear break-up time, meibomian gland morphology, subjective symptoms, and lipid deposition on lenses were measured before and after two weeks of SCL wear.
After 2 weeks of lens wear, symptomatic SCL wearers showed significantly higher fatty acid ratios and shorter non-invasive tear break-up times compared with asymptomatic wearers. J-CLDEQ-8 total scores were significantly correlated with fatty acid ratios and non-invasive tear break-up time. Prior to lens wear, symptomatic participants also had significantly shorter fluorescein tear break-up times and more severe upper eyelid meibomian gland morphology changes than asymptomatic participants.
