By far very unprofessional and illegal to charge for more expensive dilation drops without telling me. I was asked four different times after signing the paper that states it would be 30.00 dollars extra. An 80 dollar visit turned into 103.00. What a rip off to not ask if you can use the more expensive drops. Also no one could tell me how much more it was going to be. I just received a total. The only reason I didn't give that office hell and damnation is that mine and other children were there. I will never come back to this location again. No business has the right to change a signed agreement about money and services without first asking the person for permission of the changes. You too are subject to the law.
