After visiting a seminar about WVI, I received a certificate for the free evaluation and also won the grand prize for half off any necessary procedure. I’m so glad I did! As it turned out, I had astigmatism and was eligible for 3D LASIK. I could tell a difference the next day and it will only get better! Thank you Dr. Wang and everyone at WVI, with the only 3D LASIK procedure in TN!
