We have been waiting for our appointment for AN HOUR AND A HALF…read more The staff here is extremely rude and I noticed drops being dispensed without the container being sterilized. We arrived to our appointment at 10:00 am it's currently 11:33 am and we are still waiting to be seen. I understand patients taking longer than expected but an hour and a half is excessive. The office is definitely over booking patients, there aren't enough seats in the waiting room

So strange that he'd take the time to mention privacy laws when he didn't do a lick to respect our…read morefamily's privacy and harassed us even after I told him to disengage and this was not up for discussion. I have a full voicemail I'm happy to publish on here for the world to listen to, since I have nothing to hide. 1) We track our appointments electronically. On the particular day this review was posted, we had 43 appointments. Every day is different, but on this day, the average time these patients waited to be called from the reception area was 5.3 minutes, starting from their appointment time. The longest wait was 23 minutes. These 43 patients had an average appointment duration of 69 minutes, meaning that, on average, they were done a little over one hour after their appointment time. That's great to cite averages but that's not the case here. As I mentioned - we waited 1.5 hours. But the provider made it a point to say it wasn't a long time and did she really think it was that long - extreme gaslight behavior. Anybody who doesn't think a wait time of 1.5 hours at a Dr.'s office lives in a dystopian world. We have lives and things to do, not wait around for a doctor who doesn't have their scheduling figured out after 20 years in business. There is a big difference between an appointment that "takes" one hour versus a patient who "waited" for one hour. On average, our appointments take 1-1.5 hours. This is because the appointment involves many components, such as updating the medical history, conducting tests, reviewing surgery instructions, waiting for dilation drops to take effect, and, finally, meeting the doctor. Unfortunately, some patients consider the time they see the doctor as the start of the appointment, discounting all the previous components that our staff had to complete in order for the doctor to perform his/her portion. My mother has had all these events happen in previous visits. They've never accounted for 1.5 hours. In fact if you want the truth, we were told by the front desk staff once we inquired why the wait was so long - they said it was because they had to have other people go ahead of us because of "emergencies". Not our problem. If you read other reviews, the long wait times are not an uncommon occurrence for this provider. 2) If a patient complains that they have waited long, we check the electronic tracking data to identify the cause of the delay and make improvements for the future. Sometimes, the tracking data reveal that the patient has misjudged or exaggerated the actual time they waited. My mother did say it was two hours and as I stated in my review - I corrected the provider by telling him it was actually 1.5 hours and that's still a long time to wait for an appointment. Have the decency to admit your deficiency instead of trying to gaslight or lie your way through a review response. 3) As with any business that cares about its clients, if we receive negative feedback about a patient experience, we try to reach out to the patient to address their concerns. If the feedback was made in a public forum (e.g., Yelp/Google) supposedly on their behalf, we obviously need to inform the patient what the feedback stated in order to have that discussion. Yes you certainly reached out - not to address the patient's concern, but as a point of trying to embarrass my mother. It's clear as day - nobody in their right mind would ever consider your behavior a follow up, and considering it was after hours and around 7:30pm at night, past dinner time at the house. You failed to disengaged when asked politely, to not call here and hang up - at least 20 times. Most people have the intelligence to apologize and leave when asked, not to continue to harass families like this guy. 4) We treat all patients with respect, courtesy, and honesty, and we are fortunate that most patients treat us the same. Many of our patients stay with us long term (often over 15-20 years) and refer their family and friends to our office. You clearly don't treat all patients with respect, as you demonstrated both in your "in office" behavior and "out of office" behavior. Nice try diddy.

Let me begin by saying, like all people looking for eye correction treatment in the beginning, it…read morecan be daunting to think about. Not being educated on what EVOicl, Lasik, and smile treatments are, I came into my first consultations not knowing a thing. Needless to say my counselor Christine took the lead in enlightening me on which procedure was right for my eyes. For context, my eyes were both around -6.5 with bad astigmatism. She ran through the entire process and explained what to expect going into my operation. Overall, from the beginning to the end, I felt safe, secure, and well-educated in every step of the process. The surgery itself was held at their Rowland Heights location, and the office staff/ doctors were super friendly and helpful. Dr Patrick Pham knew what to say to relieve any stress going into the treatment, and was well spoken throughout. With their multiple branches, I had the pleasure of going to their Westminster location for my post-op appointments. If you're looking to get eye surgery done, look no further. IQ Laser will get you right. I am beyond happy to exclude contacts from my daily routine!

The staff is very sweet and makes every visit smooth. I met with Christine for my consultation and she informed me of the different types of procedures, healing time, etc. I was a bit anxious going into it, but Christine made sure to answer any questions I had which provided comfort. My procedure went very well and I am now 20/20! The SMILE procedure is easily one of the best decisions I've made as it's made my life so much better. I didn't realize how bad my vision was and how much of a hassle it was to deal with glasses and contacts. I've been meeting with Dr. Nguyen for my post op visit and check ups. It's always a delight seeing her. Thank you IQ Laser Vision and staff for the gift of perfect vision!

We were very worried to say the least, especially since it was Sunday and no ophthalmologists were open. We were so lucky that we happened to call Aquity Eye Group, because we soon got a call back from Dr. Elizabeth Du. She was compassionate, and so helpful, that she agreed to meet us at her office in 30 minutes! She was very professional, quickly determined that there was no detached retina, and was able to fully advise us on next steps. I would certainly recommend Elizabeth if you need a good Ophthalmologist who actually cares about the patient.

Wasted 2 hours waiting around, I was coming off of a 12 hour shift at the hospital, and my dad had to take off work for a whole week for this appointment since he's a truck driver. Also wasted $15 to park our cars in the plaza. The doctor had an emergency, OK no problem - things happen, we completely understand, but it should not have taken 2 hours of us waiting and calling around to notify us. Was told a manager will reach out to us to make it right - crickets. Spoke to Deanna from the call center and she had the stinkiest, snobbiest attitude arguing back at us, cut us off mid-sentence and was extremely rude. I also work in health care and have never displayed such unprofessional mannerism with my patients. She completely soured our experience single-handedly. Perhaps Deanna would benefit from some more professional training. The staff from the office was otherwise pleasant.
