Any surgery has its risks, and patients’ eyes may have after-effects after surgery, such as corneal infection, dry eye, secondary glaucoma, and so on. 1. Corneal infection: After myopic surgery, if patients do not pay attention to eye hygiene or often rub their eyes with their hands, it can lead to eye infections, eye redness, eye pain, eye secretion and other uncomfortable symptoms. 2. Dry eye: Because of the damage to the corneal nerves during myopic laser surgery and other surgeries, patients may experience discomfort such as dry eyes, astringency, and foreign body sensation in the eyes, and patients may also experience discomfort such as dry eye. 3. Secondary glaucoma: After eye surgery such as vitrectomy, patients are at risk of developing secondary glaucoma and other sequelae of the surgery, which can damage their vision. It is recommended that patients after eye surgery follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
