Do you know how rare it is for somebody to voluntarily write a positive review without being…read moreprompted or asked to do so? My family and I have been seeing Dr. Chao and his team for many years at both the Irvine and Fullerton locations - they are simply outstanding. In the past, we've done cataract surgery (for my dad), routine checkups, and most recently for myself, PRK surgery. In every instance, we've been absolutely impressed with Dr. Chao's team of professional, knowledgeable, and kind staff members. In 9/2020, I went to get a consultation about Lasik vs. PRK surgery with Dr. Chao. He patiently walked me through the relative advantages of each procedure and which was the right one for me. My PRK procedure (10/2020) was incredibly smooth; some of my friends had less than ideal experiences with other practitioners, but I'm happy to report my procedure and recovery process went perfectly. Dr. Chao and his team did an amazing job of caring for me, carefully explaining what I should expect, and always making me feel like I was being treated with the highest level of expertise. I just came in for my three-month follow-up and could not be happier I decided to work with Dr. Chao. It's rare to find such a wonderful team of medical professionals. I genuinely enjoy coming in to see Dr. Chao! My advice is to listen to the onslaught of five-star reviews (especially those from people who actually work in healthcare) and book an appointment with Dr. Chao's office. Don't go anywhere else - this is the type of care we should get from every single doctor.

Dr. Chao is wonderful. I had PRK surgery a couple years ago and I have 20/20 vision! Being able to…read moresee well right now is fantastic! I couldn't have imagined life this way as I struggled with near-sightedness for a long time. I recommend going to Dr. Chao for your lasik or PRK vision needs.

My once a year check up to see an ophthalmologist. I've seen two other doctors from here before…read more My last visit they were not that nice but this time they were friendly and had good bedside manners. My nurse she was really sweet she took all my tests before I met with the dr. I parked out front and you have to take the elevator up, but was a pretty quick visit. Did some tests and they dilated my pupils so that made my eyes really sensitive after that for some reason, but was able to drive home alright sort of. I was really blurry, dizzy and nauseous and felt like I needed to lay down when I got home so I did and took a nap. Never happened to me before after getting dilated, maybe this week has just been a bit much on me but I appreciated their kindness and the Dr was friendly too, I like how clean it is and they had some cute Halloween decorations up everywhere too. Was a little busy but not too bad, was out of there in less than an hour. Thank you for being friendly and kind. Have a beautiful day be kind to all your patients :) Aloha

This place is a mess. Our appointment was at 2 PM and we waited over an hour just to get called…read moreback, then another hour before the doctor finally came in, and she barely spoke to us for a minute before leaving. Total waste of time. The front desk girl was unbelievably rude and clearly not trained. The woman on the right kept insisting she couldn't find our insurance, but after I pushed back, the girl on the left found it immediately. If one person can do it in seconds, the other has no excuse. It's unprofessional and shows how poorly this office is run. This wasn't a one time issue either. This was our third visit, and every single time we've waited around two hours total just to see the doctor for barely a minute. That's not a scheduling issue at this point, this place is just consistently slow, disorganized, and disrespectful of people's time. I wouldn't come back here and I wouldn't recommend it to anyone!
