Do you need an eyelid lift or a ptosis correction?
Do you notice excess skin in the upper eyelids so your eyelid skin is literally resting on your eyelashes!? Or do you have sagging upper eyelids so the edge of the upper lid where the lashes emerge is covering part of your pupil?
You might benefit from an upper lid lift (blepharoplasty) or you might need to raise the margin of your eyelid so you can see better, or you might need both!
