1. Simultaneous measurement of tear film dynamics using wavefront sensor and optical coherence tomography

    PURPOSE: To investigate tear film dynamics using simultaneous measurements of ocular aberrations and lower tear meniscus. METHODS: Simultaneous measurements of wavefront aberration and lower tear meniscus were performed for 11 normal eyes and 7 eyes with short tear film break-up time dry eye (SBUT dry eye), which have tear film break-up time shorter than 5 seconds, using a wavefront sensor and an anterior segment optical coherence tomography (OCT). During the measurement, the subjects were instructed to blink every 6 seconds for a total of 30 seconds. From the measured aberration, root mean square (RMS) wavefront error and volume modulation transfer ...
