Don't waste your time with the referral or bother going to this place. The service has gone down hill. I paid about 3-4K for my lasik. I recommended my sister which she drop about $5k for her surgery. She had the worst experience with the staff, billing and insurance and trying to get them to do anything about it. 3-6 month. I have yet to get the $100 referral after calling a few times to find out what happen. I don't need that damn $100 and I don't need to be calling in to ask about it just to get a bs response. Don't offer a referral system if your going to find a way to screw people just to get more people to come in. I won't be going to this place any longer.
