First time to do eye exam here in vegas. And i will take my previous comment back. Because after a week, my coworker & my bro was wondering why i am paying this much. Well, its my first time.To make my story short. I just found out that they use my other insurance. Hands down, Dr.Wong is very friendly, nice, & very professional. It is just that the staff  is not as good as her. And for new pt, just a tip to shout to them what is your insurance before u will be surprise cause they will not do anything about it.
