Is this a permanent scar after lateral canthoplasty? (Photo)

I did lateral canthoplasty around 8 weeks ago in korea and i realised this bump starts to develop. I emailed my surgeon as i am back in my own country and they told me this is a normal healing process for the incision. I went to see a local derma and they told me it isn't a hypertrophic scar and it will take some time for the bump to go away as the bump is caused by the stitches that is sewed under the skin. I am not sure if i can trust their diagnosis. Please give me some advice thanks.
