There were no significant differences among all measured tear menisci variables between types of lenses (re-ANOVA,
P > 0.05 for all six measures over the three checkpoints;
Table 1 ;
Fig. 1 ) or between visits one and two (
P > 0.05;
Table 1 ). The menisci immediately after lens insertion were significantly greater than those before lens wear (
P < 0.005;
Table 1 ;
Figs. 1 and 3 ). By 20 minutes after lens insertion, the values of tear menisci had recovered to the baseline values (
P > 0.05). The repeatability of menisci measurements at baseline, lens insertion, and 20 minutes after inserting the lens were unchanged (
P > 0.05 for all 6 measures over three checkpoints;
Table 2 ;
Fig. 3 ). Changes in UTMR, UTMA, and UTMH followed similar patterns to the changes in LTMR, LTMA, and LTMH immediately after insertion of the lenses and at 20 minutes later
(Table 1) . The changes of the upper and lower tear meniscus variables were highly correlated with one another immediately after lens insertion and 20 minutes later (Pearson correlation, r ranged from 0.45 to 0.94,
P < 0.05;
Fig. 4 ).
During the third visit, tear menisci around both upper and lower eyelids were significantly increased immediately after the instillation of the lubricant (
P < 0.001;
Fig. 5 ). By 20 minutes after instillation, all the variables had returned to baseline values (
P > 0.05). There were no significant differences between lenses for any measured variable of the tear menisci (
P > 0.05). Compared with results obtained in visits one and two, no differences were found between eyes and lens care solutions with each of tested lens (
P > 0.05).
