Pterygium is a chronic inflammation that occurs in the conjunctiva and affects the visual condition or aesthetics. It can be considered to be handled by surgery, and the specific surgical procedure includes preoperative preparation, local anesthesia, surgical excision, and postoperative care. 1. Preoperative preparation: conditioning the basic physical condition, conditioning the condition around the eyeball, applying antibiotic eye drops, such as tobramycin eye drops, one week before surgery. 2. Local anesthesia: before the operation, patients can apply anesthetic drugs for surface anesthesia and subconjunctival infiltration anesthesia, so that patients can cooperate with surgical operation. 3. Surgical excision: To start the surgery, the eyelid is propped open with a lid opener to expose the eyeball as much as possible. The pterygium is surgically separated and excised. After the operation, the hemorrhage is stopped and the conjunctival rim is sutured to the periphery of the cornea. 4. Postoperative care: After the operation, patients need to use antibiotic eye drops, such as tobramycin eye drops as prescribed by the doctor, and also pay attention to eye cleaning to prevent infection. It is recommended that postoperative pterygium patients follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
