Strabismus can be performed at any age. We call on all strabismus patients to receive treatment as soon as possible, especially congenital esotropia. If treated early, binocular monocular function can be restored. If you do it later, your development will stop and your monocular function will not recover. The operation is just a cosmetic surgery. /kloc-After 0/2 years old, binocular monocular function can not be restored, and there is no stereoscopic vision. Therefore, strabismus requiring surgery must be completed before 12 years old. It is a very wrong idea to do it when you are old.
