I realize this post was done last month. And I hope you've gotten some answers by now.
That being said my doctor always told me surgery was the last last option...I've had to switch my drops a few times. Once cause they weren't working, again because I started developing a bad reaction. I felt like I was putting acid on my eyes. So I took myself OFF of those and refused to take them. (No better way to tick a doctor off, than to do that lemme tell ya!)..
I'm on Lumigan now (I don't know if those fall in one of your no-no catagories) and it seems to work fine.....I'm a tad nervous though cause I haven't been in to the eye doctor in six months (I have to go every 3 for a check) And I go friday...so I know I'll catch hell for it.
If it makes you feel any better though....I was 12 when I was diagnosed
