There were no statistically significant differences between contact lens type at the end of the study/day 90 in the CMC-HA group, although a trend towards significance was observed with Acuvue 2 compared with PureVision (p = 0.05) (Table 4 ).
A post hoc exploratory analysis suggested that higher baseline LWE staining grades were correlated with greater grittiness/foreign body sensation, dryness, ocular pain/discomfort, and light sensitivity symptoms scores throughout the day and at the end of the day (correlation coefficient [ r ] range: 0.62–0.75: p = 0.05–0.14), although correlations did not reach statistical significance.
