Association among Blink Rate, Changes in Ocular Surface Temperature, Tear Film Stability, and Functional Visual Acuity in Patients after Cataract Surgery

Figure 2

Correlation between the blink rate and the changes in the ocular surface temperature (ΔOST) (a) and noninvasive tear breakup time (NIBUT) (b). ΔOST = difference in the OST from 0 to 10 seconds without blinking.
