My eyes cross inward and my left eye is dominant. I can only use my right eye if I look to the right. My vision has not really changed much, but my eyes cross more than they used to.

Why is this and how severe will it get? I can't have another surgery because my eye muscles are messed up. I've tried excercises too but nothing worked. i've been told my eyes will be crossed for life. Now I'm kind of worried about how severe it will get as I age. I'm 24 now.
