I had double eyelids surgery using dissolvable sutures. Is this an infection? If I have a revision, can bump be removed? (photo)

A lump along the upper blepharoplasty incision one year after surgery is either a suture abscess, granuloma, or skin cyst. If the bump does not resolve on it's own in a week or so it is unlikely a pimple. All three of the other listed issues are unlikely to resolve on their own or respond to antibiotic therapy and, unfortunately, all would require a minor procedure. I recommend you return to your surgeon for a follow-up appointment for a physical examination. The sooner this is evaluated, the smaller it will remain, and the easier it will be to treat. 

You body is getting ready to spit the suture in the eyelid that is causing this.  Left to its own devices, the scar can heal in a less than ideal manor.  The best thing is to have this evaluated by your surgeon.  There are a range of appropriate management options including opening the site to explore the wound and remove the suture.  Alternatively, it may be possible to quite the skin area down with warm compresses and oral medication. I encourage you to have a dialog with your surgeon regarding your situation.

It is possible your eyelid is reacting to the presence of some remaining suture material. Have your surgeon evaluate this issue for possible treatment.
