Artificial tears, antibiotic eye drops, glucocorticoids and other eye drops can be used for pterygium, but none of them are curative for pterygium, and they are mainly used for symptomatic relief and postoperative recovery. Pterygium is a disease that occurs in the conjunctiva of the eye and may be related to ultraviolet rays, genetics, etc. If left untreated, it not only affects the appearance, but may also cause vision loss. Pterygium is mainly treated by surgical excision. Eye drops are mostly used for symptomatic relief and postoperative recovery medication, such as artificial tears for lubricating the surface of the eye, relieving ocular discomfort and promoting postoperative endothelial repair; antibiotics (e.g., oxyfloxacin, tetracycline, chloramphenicol, etc.) are used to prevent infections, and glucocorticosteroids are used to alleviate inflammatory reactions and prevent recurrences. It is recommended to use drugs under the guidance of the doctor, and go to the hospital for examination in time if there is any discomfort.
