There were no significant differences between the groups t post-1 m and 3 m, but significant differences were observed at post-1w and 2w. b Changes in fluorescein staining in the BCL and control groups after phacoemulsification. There were no significant differences between the groups at post-1 m and 3 m, although significant differences were observed at post-1w and 2w. c Changes in Schirmer test in the BCL and control groups after phacoemulsification. There were no significant differences at post-1d, 1w, 1 m and 3 m between or within the groups
