I am 28/M and living in France, and have the exact same story and external signs of CMTC as JRB206. Every single sign, which is pretty amazing given the rarity of CMTC.
I too had a heavy laser operation (in 1991), followed by mild pulsed laser experiments during my teenage years.
The part about CMTC being part of your character, and even of yourself, is totally correct. I absolutely relate to that.
I have to say it feels good to see you're not the only one with this.
