When you say sqint have you got a turn in your eye? I have a lazy eye which luckily for me doesn't look noticeable, but when I'm tired it turns in. Anyway, I was concious of it and wondered if anyone else noticed. I asked my GP to refer me to the eye clinic and they said if it was worse or gets worse I could have botox injections in the eye muscle (not sure what it does) or an op if its that bad but it's not. In th meantime they have put a prism in my glasses in the left lense (which is the lazy eye) which helps a bit.
I understand how you feel though about meeting new people. My left eye is so lazy that if someone walks towards me, say from across the road or something, I know who they are but I cant focus on them until they are right up close to me, it's so frustrating i'm sure people think I am ignorant sometimes.
I would say go ahead with the op, I understand your concerns but eye surgery is so advanced today I know 2 people who had it done and they said it was great.
Good luck.
