Anyone else experience physical changes?

I was just wondering if anyone else out there experienced physical changes after surgery like eye colour or hair colour?
About a month or so after my surgery in Sept. 2011 I noticed that my eye colour had changed from blue to green and my hair went from Blonde (like in my photo, yes that was my natural hair colour) to Brown… like at first it was dark dark brown and it has lightened up since but it’s still Brown…
Anyone else experience something similar?
My one doctor said that the body changes every 7 years and sometimes it’s subtle and sometimes it’s major like mine… my Momma had her hair go dark on her in her late 20s but her eyes never changed but everything happened to me right after my surgery…

I’ve had eye exams and all they’ve said is there was some damage to the optical nerve in my right eye but otherwise my eyes are fine. And my eye sight actually got a bit better after surgery.
