Scarring, stitches in too long

I had ptosis surgery on July 6th Doctor wouldn't remove stitches , I was very concerned because I felt they were in too long I voiced my concern twice He said the stitches dissolve July 18th, the stitches were still there , my eyes were red , stiff , aching . I cut them out ,felt better . I know but my surgeon would not , the stitches had been in for 12 days I get keloid/hypertrophic scars easily They stitch looks like a train track ,raised red bumpy scars are hard / extremely stiff
