Don't even think about the price. If they are offering it super cheap, why? Do research and check into their reputation. After all, you only have two eyes. If you go the cheap route and they screw it up, what are you going to do? If you travel out of country and something happens, ?????????
When I was researching doctors, I called a bunch of places and had them send me info on their practices. I have eye coverage where I work and they have certain places that you HAVE to go to inorder to be covered. I discussed a bunch of options with my eye doctor. He told me some horror stories of some of those "cheaper" places. The place that my insurance provider recommend also had a couple bad incidents with local people that my doctor knew about.
I weighed all my options and decided to go with a doctor that was 300 miles away and wasn't covered under my plan. It cost me more money, but I am happy.
I won't even think about going with a cheap place, I just figured $500 a eye was going rate here until I seen the other price, good idea actully about talking to eye doctor, i'm sure they would know good places to go. I'm going to research it a lot more, and yes price isn't even a factor you should consider.
