How is strabismus surgery done? Simply put, strabismus surgery is about adjusting the balance of the extraocular muscles, which means that the strength of the extraocular muscles is balanced so that the eye is in a normal position. In the case of exotropia, for example, the surgery is to reduce the strength of the muscles that control the outward movement of the eye and strengthen the strength of the muscles that control the inward movement of the eye, reducing the strength of the external rotation and strengthening the strength of the internal rotation, so that the eye can return to its normal position. What are the risks of strabismus surgery? The risks of strabismus surgery are generally not significant, and it is one of the less risky types of eye surgery. It is an external eye surgery, which does not open the eye, does not affect the vision and does not affect the internal structure of the eye, but mainly adjusts the attachment points of the extraocular muscles on the surface of the eye. This surgery has a history of nearly 200 years and is still very safe.
