The technique of the operation depends on the desired need. For example, strabismus eye surgery is done by treating the cause of strabismus through the muscle connecting the eye. The reason is the relaxation of the eye muscle, it can be shortened or stretched. .
In all cases, strabismus is treated at the muscular level and not at the nervous level. As for rejuvenation operations, they are done by tightening the skin and the flabby muscles around the eyes to get rid of all the excess flabby skin and the effects of wrinkles. Even some wrinkles around the eyes can be treated with injections of Botox that reduce muscle contraction and therefore their appearance.
Sunken eye surgery is also done by injecting the filler under and around the eye and does not require a surgical incision. As for the expansion of the eyes, it is done by removing the drooping eyelids and removing part of the eyelid if necessary.
