Is my left eye infected? And are the stitches fixable? (photos)

I had upper eyelid surgery (Blepharoplasty) 2 months ago, one eye looks like the stitching was done really bad and now it's starting to swell again after 2 months. Can the bad stitching get fixed? And how long should I wait before I do it. I look so horrible and can't look at the mirror anymore. Also what can I do about the pain and infection in my left eye
