Most strabismus requires surgery because conservative treatment does not work well. However, parents always feel that conservative treatment can work and are fearful and doubtful of surgery, fearing the risks of surgery. If the child’s strabismus is too large to be treated by conservative methods such as wearing glasses; and, the examination reveals that the visual function of both eyes has been affected, such as the fusion function of both eyes has started to be destroyed, then surgery should be done as early as possible. If the child is too old, it will be difficult to restore the visual function after surgery. At present, some parents have concerns about adopting general anesthesia for younger children who cannot cooperate with strabismus surgery, but there is no need to do so. As long as the child is in good health before the surgery and does not have a cold, fever or diarrhea, it is fine. In addition, strabismus surgery does not destroy the internal structure of the eye and will not adversely affect vision. The surgery is performed on the surface of the eye, and the attachment points of the muscles that control the rotation of the eye are adjusted to bring the eye back to its normal position. It is normal for the conjunctiva to become engorged and edematous after surgery, but this will soon subside and parents should not worry too much.
