Surg Increasing the Volume of the Muscle Close to the Eye in Lieu of Fillers

Increasing the volume of the thin muscles around the eye is not only impossible without damaging them and risking eye movement and double vision problems but, even if this was possible, it could NOT improve the appearance of the eye. (Consider the appearance of hyperthyroid eyes in which the eye globe appears to bulge owing to the increased swelling of the fat and muscles around the eyeball pushing it out).
