The type of strabismus varies and so does the type of surgery used to correct it. The general principle is to weaken the strong muscles and strengthen the weak muscles. Strabismus surgery can be performed under local anesthesia or under general anesthesia. The specific steps are as follows: 1. Make a small incision in the conjunctiva. 2. Hook the operated muscle with a strabismus hook, separate the nodal ligaments, and make a double set of muscle loop sutures. 3. Posteriorly migrate or break the tendon of the strong muscle, and truncate or fold the weak muscle. 4. Suture the conjunctival incision. 5. Wrap both eyes or one eye, and the operation is finished.
