Would you recommend canthoplasty or just a blepharoplasty? (Photo)

I went to a Dr. about an upper and lower blephoplasty. She also, suggested she put a stitch in the outer corner of my eye and do a pinch. Then suggested she do a Canthoplasty to help tilt my eyes up which she said would change the shape of my eyes but give them some lift. She said it would take a year to loosen and if I didn't like it after that she could snip it and it would relax more. Would that procedure make my eyes smaller and not as round?
