Eye muscle surgery is a procedure to weaken, strengthen, or reposition any of the muscles that move the eyeball (the extraocular muscles).
The purpose of eye muscle surgery is generally to align the pair of eyes so that they gaze in the same direction and move together as a team, either to improve appearance or to aid in the development of binocular vision in a young child. To achieve binocular vision, the goal is to align the eyes so that the location of the image on the retina of one eye corresponds to the location of the image on the retina of the other eye.
