The whole process of pediatric strabismus surgery includes preoperative examination, anesthesia, sterilization and surgery. 1. Pre-operative examination: Strabismus surgery needs to complete electrocardiogram, chest X-ray as well as blood routine, urine routine, stool routine and other tests. 2. Anesthesia: Most older children and adults can cooperate, so strabismus surgery can be done under local anesthesia. Infants and young children can not cooperate, in order to ensure the safety and smooth operation, the operation must be performed under general anesthesia. 3. Sterilization: After general anesthesia is successful, saline is usually used to rinse the conjunctiva, the surface of the eye and other disinfection. 4 Surgery: Surgery should first incise the bulbar conjunctiva, and then separate the subconjunctival muscle tissue, line excision or posterior displacement. Strabismus surgery has been relatively mature, low risk rate, the results are relatively good. After surgery, attention should be paid to eye care.
