Mean changes between time points were reported preceding 95% confidence intervals in parentheses.
†Median changes were reported.
**p < 0.05, the negative significant value indicates TheraPearl decreased OSS by 1 more than Blephasteam and vice versa at 6 months.
OSDI ocular surface disease index measured on a scale from 0 to 100, FBUT fluorescein breakup time measured in seconds, OSS ocular surface staining scored with the Oxford grading scheme from 0 to 1542, MQ meibomian quality scored on a scale from 0 to 24, ME meibomian expressibility scored on a scale from 0 to 3.
