Pre-operative preparation for strabismus surgery: 1. Children who are ready to receive strabismus surgery should not do fine visual training such as tracing and needle threading before surgery to prevent artificially affecting the quantification of strabismus surgery. 2, eye preparation: 1-2 days before surgery with antibiotic eye drops, 3-4 times a day, can effectively prevent the occurrence of infection after surgery. 3, whole body preparation: it is recommended to wash your hair and take a bath one day before surgery to do a good job of cleanliness and hygiene, but pay attention not to catch cold and flu. 4, female patients please avoid menstruation period, so as not to increase the possibility of intraoperative bleeding and postoperative infection. 5. Patients taking aspirin and other anticoagulants should stop using such drugs for at least one week before surgery. Preparation on the day of strabismus surgery: 1. Local anesthesia patients: eat a small amount of breakfast in the morning of surgery, fast for more than 3-5 hours before surgery to avoid nausea and vomiting during surgery, which will affect the surgical effect and lead to postoperative infection, please do not be overly nervous during surgery, and should actively cooperate with the doctor. During the operation, there will be 5-10 minutes of soreness and discomfort in the operated eye, which almost every adult patient can tolerate; if serious discomfort such as chest tightness, panic and cold sweat does occur, please inform the surgeon in time and suspend the operation if necessary. 2. Patients under general anesthesia: fasting and drinking after 10 o’clock the night before surgery. The strabismus surgery corrects the eye position, and the patient’s eyesight is “well water”. Some children who have had strabismus surgery in the future, such as poor vision, first need to consider the refractive error factor, parents must not “blame” the child’s poor vision to strabismus surgery, must be clear, the future vision and the current surgery has nothing to do. 2.Patients often experience eye redness, swelling, difficulty in eye rotation, foreign body sensation, double vision and other discomforts after surgery, some may feel different degrees of eye pain or difficulty in sleeping, the above phenomenon is a normal reaction after surgery, its severity and duration varies from person to person, generally 2-5 days can be relieved, do not worry too much. 3.After surgery, local antimicrobial eye drops and eye ointment are ordered to the operated eye. 4-6 times during the day, 10-15 minutes between the two eye drops, wash your hands before pointing the eye drops. Use the eye ointment at night before going to bed, and continue local medication until 3-4 weeks after surgery after discharge. 4. Minimize eye rotation and do not rub the eyes within 2 weeks after surgery. Wash your face, hair, and shower to avoid water in your eyes and prevent postoperative infection. One month after surgery, the muscles are still in the proliferation period, patients should not take big supplements, eat less fish and meat, and eat a light diet. Avoid spicy diet. 5, patients and their families should have a correct understanding of strabismus surgery, that is, surgery can only correct the eye position, can not cure the cause of the disease. The root cause of the disease lies in the abnormalities of the centers in the patient’s brain that control the collection and dispersal of the eye, not in the eye itself. Therefore, patients should understand that strabismus may be overcorrected, undercorrected, recurring, or the head position does not improve after surgery, and should not blindly have too high expectations for the results of strabismus surgery.
