I know how you are feeling, over the years I've had many laser sessions 100s of 'zaps' on both eyes. I also now have to have more stuff done soon being as I am virtually blind in my left eye. The next thing for me is a Vitrectomy operation. (Google it) I'm told it takes about an hour & I will be awake the whole time.
I could write a book on the stuff I've had done on my eyes over the years they desperately qre trying to save my sight for me.
God Bless 'em all at the Southend Eye Hospital. 10 - 15 years ago I would certainly have been blind by now, thank God I'm living in 2012.
GOOD LUCK to you take care.
