Table 7. Tear Osmolarity in Eyes with Pterygium Pre-excision vs. Post-excision.
The majority of studies demonstrated statistically significant improvement in tear osmolarity post-excision of pterygium. Only one study demonstrated no difference, which was found to not be statistically significant. The results seemed to be independent of surgical technique.

Statistically significant

Significant for no recurrence of pterygium at three, 12 and 18 months; significant for recurrence of pterygium at three months post-excision; not significant for recurrence of pterygium at 12 or 18 months post-excision
