"18 months and still waiting!"

I have been waiting 18 months for squint surgery and I am still in the dark about the exact procedure due to always seeing a different consultant each time attend, resulting in very different opinions. How can you make someone sign a consent form and accept a list of possible procedural errors when you can't even tell them what the procedure will be! I have had quite a few wasted trips at my expense and suffered long waiting times, resulting in £15 car park bills. I still don't know when surgery will be and I doubt if they do either. I've never felt so let down, so much so that i'm thinking its safer and far less stressful to live with my problems.
