Patient Thoughts

  • Dr. Louis J.F. Yang checked my eyes throughly then quickly diagnosed that my eye has Viral conjunctivitis. I asked what were the differences between all other similar symptoms like pink eyes etc.. he explained the differences clearly and educated me patiently about the reason why he thought it was viral conjunctivitis not others. Respect the professionalism he has!

  • I saw Dr Louis Yang today. He is trustworthy and very knowledgeable. Both my friend is seeing him and I am impressed with him taking his time to review and explain the condition of my glaucoma after examination

  • I was diagnosed with cataracts in both eyes and went to Dr Chern. He explained the surgery and I felt very comfortable having him do it. I will definitely come back for further eye checkups.

  • Great eye doctor! The doctor was very thorough with her exam. They asked if I would be looking at glasses in their office and were not pushy at all. I did end up getting glasses from them because of their great assistance in picking a good pair.

  • Thank you, Dr. Koo for making me feel 100x better about my recent procedure! I had a mole on my eyelash line, which I had removed 6 days prior to my visit to POG. I freaked out because my eyeball was still super red - 3 days after the procedure, and the area of the removal was still hurting. I was worried that the doctor I went to botched the job and ruined my eye, but after Dr. Koo checked it out, I felt much more at ease. He said she did a good job and kept most of my lashes. He gave me some tips about aftercare, followup and game me some ointment to prevent infection. Yay for Dr. Koo

  • I have been a patient since '09., when Dr. Chern performed a corneal graft. This man has the steadiest hands! Dr. Chern is patient and comforting, I wished I had been his patient long before I had to have a transplant. Highly recommended. Dr. Katie Waters is wonderful. She is extremely patient, kind and caring. Due to my eye disease, I am not a routine contact lens fit, Dr. Waters makes it look easy and keeps me at ease. I only wished she worked this office five days a week making it easier to schedule with her. Dr. Waters in my EYES is an asset to the practice. Thanks to the staff as well, you are always very accommodating and pleasant.

  • I "heart" Dr. Koo. I really do. I have him to thank for figuring out what was wrong with my eyes (and my contact lenses). The discomfort started in November of last year. I could barely stand to wear my contacts for more than a few hours. They were getting red, teary and sensitive to light. I started having to wear sunglasses just to work in front of my computer. My reglar eye doctor couldnt figure out what was wrong. My wedding day was approaching and I was getting panicked that I'd have to walk down the aisle in my wedding dress, wearing glasses, because I couldn't stand my contacts anymore. So I went to Dr. Koo because his reviews were fantastic. I figured he would know what to do. On my first visit, he swapped my brand of contacts to Acuvue Oasys. Still no results. Then he figured out that the curvature of my eyes had actually changed slightly, so I needed a slightly wider lens. This was unusual. He says 80% of people will do OK with any contact lens curvature, but my eyes decided to become sensitive all of a sudden. Within a day in my new lenses, my eyes felt fantastic. No more tears, no more sensitivity to light, no more redness. I can't believe my original eye doctor couldn't figure this out himself! Needless to say, Dr. Koo is my go-to guy from now on. I should also mention that Dr. Koo is not in my vision network (They take VSP but I have Blue Shield MES Vision). But he is so great I was willing to pay $60/visit just to see him. When it comes to my vision, I don't want to take chances so it's worth every penny. Besides being a great opthalmologist, Dr. Koo is really quirky and funny. He made me feel comfortable and relaxed in each of my visits. He took the time to answer all of my questions, and explained what was going on with my eyes at every step. I never thought I'd actually ever enjoy going to the eye doctor, but with Dr. Koo I know with 100% certainty tat I am in the very bestofhands. The staff is great, too. I also love that I can park in the adjacent garage, so it's really convenient. I highly recommend them!
