Patients need to be aware that there are risks associated with any surgery and that no surgery has a 100% success rate. The success rate of strabismus surgery varies greatly depending on the cause of the strabismus. Surgical treatment of strabismus involves surgery on the eye muscles, including relaxing (weakening) or shortening (strengthening) one or more of the extraocular muscles in one or both eyes. Strabismus surgery is performed not only to improve the appearance, but more importantly to establish visual function in both eyes. Generally speaking, if the strabismus is caused by a single factor, such as common exotropia, the success rate of surgery is high and most patients (80%) can return to normal eye position after surgery, but compound strabismus will also have a lower success rate and may require multiple surgeries because of more causative factors. In addition, the reconstruction of visual function after strabismus surgery is also very important. It is important to restore binocular visual function as much as possible through some training, and through a normal binocular visual function, it will be possible to keep the orthotropic eye position for a long time, then the success rate of this surgery will be improved. In conclusion, strabismus correction surgery is a very mature procedure and the success rate is highly dependent on the type of strabismus, the age of treatment and the postoperative reconstruction of visual function.
