Pterygium has the potential to recur, and whether it does or not is related to the patient’s condition and physical fitness. Pterygium is one of the common clinical ocular surface diseases, which is a chronic inflammatory disease caused by localized bulbar conjunctival fibrous and vascular proliferation. Pterygium usually cannot be eliminated by medication and can only be cured by surgical treatment, but recurrence may also occur after surgery. There are many reasons for postoperative recurrence of pterygium, such as individual differences, choice of surgical method, postoperative care, whether to take medication on time as prescribed by the doctor, and whether to follow up on time. Generally, young patients have a high possibility of recurrence, and patients with serious conditions also have a higher possibility of recurrence. It is recommended that after pterygium surgery, patients should follow the doctor’s instructions, have regular checkups, and consult the doctor when discomfort occurs.
