I had a cataract fixed a few years ago then about a year later,my retina detached in that same eye and I was two hours from anything in the hills..Time I got the trailer hooked up and home carefully,it was to late to fix it...So they put an eye buckle in that eye and I could atleast see in it instead of just orange..Now the buckle is coming out and bleeding...Fun Fun but I still can see unlike when it detached!
