Strabismus is a condition in which both eyes are not parallel and cannot look at one target at the same time. The most common types of strabismus are internal strabismus and external strabismus. Internal strabismus is commonly known as “crossed eyes”, while exotropia is often characterized by excessive whites in the eyes. Strabismus not only affects the development of binocular vision, resulting in amblyopia, but also affects the psychological well-being of the patient, especially in children, causing low self-esteem. For adults, strabismus can seriously affect the appearance, employment and choice of spouse. Children are the flowers of the motherland and the hope of their parents. If a child has strabismus, it is important to detect and treat it as early as possible so that it will not have an impact on his future life path. The minimally invasive strabismus surgery under the microscope carried out in our hospital is the safest, least invasive and most precise strabismus surgery available. The child’s surgery is performed under general anesthesia, eliminating the child’s fear of surgery, and the surgery is just like sleeping.
