The main precautions for eye surgery are as follows: 1. Pre-operative precautions, pay attention to any increase in secretions from the eye, if there is an increase in secretions, first apply levofloxacin eye drops, 4 times a day, 1 drop each time, for anti-inflammatory treatment, and only after the inflammation subsides is eye surgery feasible. In addition, patients with hypertension and diabetes should have their blood pressure and blood sugar controlled within the range required for surgery before eye surgery is performed. 2. Intraoperative precautions, eye surgery is a very delicate operation and the patient’s cooperation is very important. Avoid getting water in the eye within two weeks, use eye drops regularly according to the doctor’s instructions, do not rub the eye hard, and review regularly. If you experience eye redness, eye pain, or loss of vision, go to a regular eye care facility for examination in a timely manner to avoid delays.
