  1. P<0.05 was regarded as significant difference
  2. VAS visual analog scale, TMH tear meniscus height, FBUT first break-up time, ABUT average break-up time, WMCGs warming moist chamber goggles, SH sodium hyaluronate
  3. *Self-comparison (post-treatment values compared with baseline level) by paired t test with Bonferroni correction
  4. **Comparison between the two groups at the same timepoint by independent t test
  5. aComparison between the value at 30 or 60 min and at 5 min after treatment
