Strabismus is one of the most common eye diseases in children. It affects not only the aesthetics but also the development of visual function, and timely surgery can not only improve the aesthetics but also restore the visual function of both eyes as much as possible. In some children, in addition to horizontal internal or external strabismus, there is sometimes a vertical strabismus. It is routine to perform the procedure in steps, first resolving the main contradiction and then reoperating to adjust it, some requiring three surgeries. We win the satisfaction and trust of parents by giving the appropriate surgical plan through a detailed preoperative evaluation, resolving the strabismus in one go as much as possible, and avoiding the risk of multiple anesthesia.
