After pterygium surgery, topical antibacterial drugs, glucocorticoids or artificial tears can be applied for follow-up. Pterygium is a fibrovascular-like tissue, which can be connected to the conjunctiva and grow towards the corneal surface, and it usually occurs in the nasolateral blepharosphenoid region. Pterygium is small and does not need treatment when it is stationary, and when there is progressive development, it invades the pupil area, and it can be treated surgically, but there is a recurrence rate. In the postoperative period, topical antibacterial drugs can be applied to prevent infection, and when there is postoperative inflammation, topical glucocorticoids can be applied to reduce the inflammation, and also inhibit the proliferation of fibroblasts and capillaries to prevent the recurrence of pterygium. After surgery, artificial tears can be used to lubricate the ocular surface to promote tear film repair, dilute soluble inflammatory mediators on the ocular surface, and reduce discomfort. After pterygium surgery, it is important to minimize stimuli such as sunlight, wind and sand, and pay attention to eye care to prevent recurrence as much as possible.
