Wound not recovering after warts laser treatment. (photos)

Hi, I've wound after warts laser treatment in my left leg toe. I tried few antibiotics creams with dressing but don't recover well. Dr told me that new screen is not growring and there are some kind of scars. It's almost seven months but not recover. Any expert advice can tell me what's the issue and how to treat it ? Thanks in advance PS - I know I still have some warts but no worry much about it. Now My main problem is wound.
