Because you do not meet the minimum state requirements for vision, she is required to fill out the TN State Eye Specialist Form outlining your visual difficulties and send it to the DMV. You will not pass the DMV eye screening and that would trigger a suspension also.
You should also know that once she has informed you that you cannot legally drive with your vision should you get in an accident your insurance company may not cover you for the damages since you are fully aware you cannot legally drive.
You have several options: see if there is a way to financially have the surgery this year, take public transportation, or continue to drive and pray nothing happens until you get the surgery.
