Simply put, from the lower eyelid down, it is a surgical method to make the eyes bigger by artificially causing the lower eyelid to contract. If the inner and outer canthus surgery is to open the big eye fissure from the inner and outer canthus, and the levator palpebrae superioris opens the big eye fissure from the upper eyelid, then the lower eyelid is opened from below, so that the part of the lower eyelid covering the eyeball is reduced and the eyes are exposed more. In other words, the lower eyelid is completely feasible in theory. As for the effect of the operation, it depends on the skill and experience of the plastic surgeon. This is not a prohibited operation. If you find an excellent plastic surgeon to do it, the eyelid shape after the operation will be very beautiful.
