Do not recommend. The technician who performed the eye exam was very knowledgeable but has since left the office of Dr. Koo. She does not come across as being dedicated to her patients as she works only part time. Not knowledgeable regarding my cornea conditions: Instead of giving specifics about the specifics and referring me to other specialists, she asked me to consult Google. Was not thorough. Lack of professionalism.
I have been seeing Dr Cheng for about 5 years now and feel she is a wonderful doctor. She has top notch skills and is up to date on all things related to my ocular health.

Dr. Vinca is caring and dedicated doctor. When I was having trouble with my eyes, she took me in IMMEDIATELY and found that I had a torn retina. She then directed me to a retina doctor, at once.
