1. Lower volumes of tear menisci are associated with dry eye symptoms in contact lens wearers

    Purpose: To investigate tear meniscus volumes during short-term wear by soft contact lens (SCL) wearers with dryness symptoms. Methods: Three groups of 20 subjects were recruited. Group 1 consisted of SCL wearers with self-reported dryness. Group 2 consisted of asymptomatic wearers. Group 3 was composed of asymptomatic non-lens wearers. Contact lenses were fitted on each eye, and both upper and lower tear menisci were imaged before lens insertion, immediately afterwards, and 30 min later, using optical coherence tomography. Custom software was used to yield the tear meniscus area and then the volumes were calculated based on eyelid length. Repeatability was ...
