Pterygium is a very common disease in ophthalmology, and treatment for this disease is currently surgical and can be discharged in 1-2 days after surgery. The procedure is relatively simple and involves removing the hyperplastic pterygium tissue, from the surface of the eye. To avoid recurrence of the disease, a conjunctival flap with stem cells is taken from another part of the eye and placed over the pterygium to reduce the recurrence rate. Therefore, if the pterygium is present in the eye and has proliferated, resulting in corneal astigmatism or vision loss, in this case, surgery can be performed in a regular hospital. After surgery, antibiotic drops and glucocorticoid drops should be routinely applied to avoid local infection.
