The authors have advised there are some mistakes in the mean changes and standard errors of the paper:
1. The standard errors of groups Placebo and VApal were all the same value for staining and symptom scores in Figure 1 (on page 1875) and Figure 3 (on page 1876), and Table 3 (on page 1877).
2. There were slight discrepancies in the Mean changes of Placebo group at 1, 2 and 4 weeks in Figure 3D.
3. There was a slight discrepancy in the Mean change of foreign body sensation in Placebo group at 1 week in Table 3.

The authors have advised the errors were due to:
1. The standard error listed in a different table on the statistical analysis software was adopted.
2. There were typing errors when transferring numerical values from statistical analysis software to graph creation software.
3. There was a mistake when rounding numerical value.

Since the statistical analysis had been performed using the original mean values (correct values), all results do not change.

The authors apologize for these errors and advise they do not affect the results of the paper.
