Dr. Cheng and her staff were very professional on my first visit.They took the time to answer all of my questions. I chose Dr. Cheng for Lasik based on several factors:
1) Knowledge and Passion that she has for her clients.
2) Visx S4 Laser Machine
3) Accesibility to her staff as well as to Dr. Cheng 24/7
4) The office was near my house
5) Competitive price.

I higly recommend Dr. Cheng, the operation was a success.
