There is no such muscle as the double eyelid levator, the only levator muscle involved in double eyelids is the upper eyelid levator, which is the muscle you rely on primarily when opening your eyes. If you have a mild ptosis, we can do a simple shortening of the levator muscle in conjunction with the double eyelid surgery. Most people are likely to just need a little bit of loosening and don’t need to do the levator muscle. This means that the treatment of the levator muscle varies from person to person, and not every blepharoplasty requires a levator muscle. You can see how much of the eyeball is exposed before surgery. If the eyeball is less exposed, as if the eye is not open, then the levator muscle is usually needed. If your eyes feel big and already very bright after opening them, then you don’t need to do the levator muscle.
