Table 5. TBUT in Eyes with Pterygium Pre-excision vs. Post-excision.

The majority of studies found that TBUT improved after pterygium removal in the affected eye. Improvement was seen across varying surgical techniques as seen above. Improvement in TBUT was seen earliest at the four week mark status-post pterygium removal.
