    My mother had cataracts surgery here, and it was an extremely positive experience. Everyone in the office has always been so kind and professional. The office is very clean, well taken care of, and has plenty of seating. Both Doctor Lin and Doctor Ngai made my mom feel so comfortable. The after care instructions were explained carefully, and all questions were answered thoroughly.I highly recommend them! Thank you so much.

    My family and I LOVE Dr. Ngai, his staff Erick and Krystina who helped us so much caring for my brother. I have met with a lot of doctors in my profession and also personally as I often take my parents and family members to visit all kinds of specialists. I have never met anyone as kind, caring, professional, and compassionate as Dr. Ngai towards his patients. I am forever grateful not only for the best glaucoma treatment that Dr. Ngai has provided for my brother but also for his going above and beyond the call of duty as he listened to all the concerns that my brother had and patiently explained things to calm him down. My brother had to go back to Cambodia soon after the surgery. He had a lot of anxiety during the recovery there but was able to get all his questions and worries addressed by Dr. Ngai via email and video chat. If it wasn't for this level of care, my brother and I would be in really bad shape. If you are searching for a top-notch ophthalmologist who truly cares for both the patient's eye conditions and whole well-being, look no further. Dr. Ngai always has my highest recommendation.

    Dr. Ngai is amazing! Super through and I did not feel rushed and he gave me undivided attention and care. He made me feel much better after the exam he's definitely one of the best doctors of her. Super knowledgeable he's very accredited. Very professional, very smooth process the reception was even able to text me directly from the office phone. Everything was very straightforward very streamlined. I did not have to call a ton of times to get answers it was a very easy process. Excellent excellent care. I am a medical professional myself and he is my doctor forever. The male tech is super skilled even though there are a ton of tests On initial visit, He explains every one to you and the purpose. Modern and advanced care. He has his medical reasons for why he prescribes and what he does what he does and absolutely I trust his medical judgment.

After an appointment here you can see clearly now. 5/5 Service You can book appointments online, I tried but actually had a question, called and booked over the phone with an appointment that same week. Online it only had appointments a week out. The staff is always very helpful from the front desk, to those helping with the eye tests to the Doctors. 5/5 Selection Large selection of glasses, from designer to generic brands. Glasses or shades at night. Transition to regular lenses there are options for you. 5/5 Parking They have designated spots for this location which is nice when the shopping center gets busy.

    I would give Golden Optometry zero stars if I could. This is not the first time I have had an issue…read morewith this office, it has happened multiple times, and I am completely fed up. I scheduled an appointment for 4:00 PM. That is the appointment time I was given. I showed up expecting to have my exam, only to be told that I could not be seen because the doctor was no longer available and that I was supposedly required to check in by 3:40 PM. Excuse me, but WHY was the 3:40 PM check-in time not clearly provided when I made the appointment? If patients are required to arrive 20 minutes before their scheduled appointment or risk losing their appointment, that information should be clearly communicated at the time of booking. And here's the worst part: NO ONE CALLED ME. Not a courtesy call. Not a warning. Not a message saying, "Please arrive by 3:40 because the doctor will not be available after that." Nothing. I wasted my time driving there, only to be told that I couldn't be seen. And this isn't an isolated incident, it has happened several times. A medical office should respect its patients' time and communicate important scheduling requirements before the patient shows up. Instead, I was left to find out the rules only after arriving at the office. Absolutely unacceptable. If you don't want to waste your time, make an unnecessary trip, and potentially get turned away because of information they failed to communicate, I strongly suggest going somewhere else.

    Positive review. 4-months Post-surgery OD:20/20 and OS: 20/15…read more I think many of you reading reviews right now are going back and forth about having vision correction surgery. Some of you might be like me and have extremely high myopia and want the vision freedom. From my experience, I researched ICL surgery since 2019. Once EVO ICL was FDA approved, I started looking for a surgeon for advice and see if I was a candidate. Before choosing IQ Laser Vision, I had gone to a different surgeon and he did say I was a EVO ICL candidate, however I was not impressed by him. I was later referred to IQ Laser Vision, where they contacted me and scheduled an appointment to see if I was a candidate. Their multiple offices made it easy for me to go meet with an advisor and doctor. However, with personal reasons, I was unable to get the surgery done during that year after that initial consult and going through their state of the art arcscan (apparently they're the only office that are using this technology to make sure to see if your eye has enough space/vault...very cool). Fast forward March 2026, I contacted IQ laser vision again in hopes that maybe I can ask them for another consult. Again, the advisor walked me through, doctors did their check up, arcscan again (still cool) and I was able to schedule my surgery. It was an honor to have Dr. Robert Lin be available to do my EVO ICL surgery. He was incredibly patient with my questions, listened to my story of researching this procedure, and I knew I was in good hands from someone who had worked on so many eyes. Perhaps my favorite part aside from the whole journey of vision correction and having 20/20 vision is that you can feel how much Dr. Lin cared for his patients. He called me personally to make sure my first day post surgery was ok. And even after 4 months later, he contacted me to make sure I was ok and how I am liking my vision. For those who are like me going back and forth about vision correction, I highly recommend making an appointment/consult to see if you can be a candidate. From there you can move forward and make that decision. I know it was later than I anticipated for myself, but I can truly say I am happy having that peace of mind that I can wake up and see, not have to worried about my glasses/contacts during a possible evacuation (fire or earthquake), and do water sport without fear of infections if I wore my contacts. That mental peace is probably the second to best part of this journey.

    Overall, I am genuinely so happy with the results of my EVO ICL surgery--waking up with clear…read morevision has been truly life-changing! From my initial consultation through speaking with the counselor and completing all the intake steps, the customer service was fantastic. Every single employee you interact with out front is so warm, friendly, and welcoming. During all the preliminary scans and tests, the staff members were so gentle and reassuring, explicitly reminding me that having a strong, involuntary reflex to squeeze my eyes shut is completely natural and normal. The only small hiccup leading up to the day was that I didn't find out my surgeon's name until I arrived for the procedure; while everyone on their medical team is clearly exceptionally qualified, knowing who would be performing the surgery ahead of time would have added that extra layer of comfort. Still, I walked into surgery day feeling well taken care of and deeply grateful. :3 What surprised me most was the jarring contrast once I was behind closed doors. While the front-facing team is wonderful, the pre-op technician prepping me for surgery was basically the exact opposite. Because technicians in the back are behind the scenes and rarely mentioned in public feedback, several people urged me to write this review so others are aware. Even after my numbing and dilation drops, my eyes naturally wanted to close when forced open. This pre-op technician became visibly impatient with my reflex and used more force rather than give me a few seconds to let me relax my own reflex. While I don't recall her exact words, the message communicated was that if I couldn't keep my eyes open, the surgery wasn't going to be done right. This happened for BOTH eyes where I heard the other technician preparing with the surgeon stop what they were doing to make sure everything was OK on this end of the room. Hearing that theme of this will be my fault if anything goes wrong while trying to prep myself for the surgery, feeling the oral sedative hadn't fully quelled my nerves, triggered this intense anxiety. Basically, the whole time I was awake, I desperately wanted to follow instructions to look up and relax my eyes, but I was made to feel like I wasn't doing things "right" before the surgery began. It made the entire process excruciatingly nerve-racking, and I sat there spiraling with regret, thinking I never should have gone through with an elective, "nice-to-have" procedure if the potential consequences were lifelong blindness. The situation escalated right before the procedure began during the standard timeout. This same pre-op technician read off the wrong eye specifications and dimensions for the eye we were starting with. Frozen in fear and second-guessing myself, I hesitated to speak to trust the process aka assuming I had to trust the clinical team and their 300,000 success stories and I would be another one. Thankfully, the primary surgeon immediately caught the discrepancy and corrected it on the spot. Right before the doctor started the surgery, I told him hearing the wrong eye measurements was scary, he reassured me that they double check everything. While I am profoundly grateful for the surgeon's attentiveness and skill--which ensured the actual surgery went smoothly--having a pre-op technician read incorrect eye measurements after reprimanding me created acute distress. I spent the rest of the procedure awake and terrified of what could have happened had the surgeon not caught the error. I felt distressed about it the whole day after the surgery but my priority was my own healing post-op. Nonetheless, I did speak up at the next day follow-up. I brought the issue to my counselor, who escalated it to her manager. While the manager offered a sincere apology and provided some extra eye drops, a company of IQ Laser Vision's size and caliber should have done more to substantively address a clinical safety and bedside conduct issue of this magnitude. A comped bottle of drops and a verbal apology do not undo the psychological distress of that day. My results are great to never have to put on and off my contacts daily and being able to see ALL THE TIME. But.. whenever people ask me how my surgery went and whether I'd recommend IQ Laser Vision, this is still the defining part of the experience that immediately comes to mind.

After receiving a wristband--which was the only part of the process that happened efficiently--we waited approximately 45 minutes for the first test, then another 37 minutes for the next one, followed by additional waiting for more testing and to see the doctor. It appears the office is severely overbooked. We were there for more than three hours for a scheduled appointment. I understand medical appointments can run behind, but this level of waiting and disorganization is unacceptable, especially for elderly patients.

    I found Dr. Zhu's office by chance today because my husband had an appointment in the same building…read moreand same floor as her office. As soon as I exited the elevator, I noticed it on the left hand side. It immediately caught my attention because LASIK is something I've been wanting to do for years. After my husband's appointment I had a little bit of time and thought to go in and ask a few questions. They were able to see me as a walk-in and the whole staff were extremely friendly. After my testing, I waited for a bit and Dr. Zhu checked in on me and let me know it'd be a little longer. The wait was a little long but Evelyn came in and took me into her office to give me the price break down until the Dr. was free which I liked so I wouldn't have to wait too long. The pricing is competitive and reasonable. Unfortunately I wasn't able to see Dr. Zhu because I had to pick up my kids from daycare. I understood that I was a walk-in and there were patients there with actual appointments. I'll be returning on Thursday to finish my appointment and hopefully if all goes well I'll be scheduling the treatment shortly after. I can only imagine the care would match the customer service.

    Dr. Dagny Zhu is nothing short of incredible…read more As a fellow healthcare worker, I never thought I'd find myself writing a review for a surgery, but Dr. Zhu is one of a kind. As a pediatric general dentist, I'm seeing 40-80 kids a day - to say my vision is critical is an understatement, and I'd only be trusting my eyes to the best. LASIK has completely changed my daily clinical and non-clinical life, and even 5 or so years after my original surgery date, easily remains one of the best health related expenses I've ever done. For those of you interested in the academic side of things, Dr. Zhu is well credentialed - a Harvard graduated MD, with Ophthalmology residency at the Doheny Eye Institute / USC & Los Angeles County Medical Center. Her fellowship was at Bascom Palmer Eye Institute. As if that's not enough, she still does research and mentors upcoming residents. This level of training and active commitment to the medical community as a whole speaks volumes to the caliber of clinician that Dr. Zhu is and aspires to build unto others. Non-academically, Dr. Zhu herself is incredibly personable, and shows an unwavering commitment to her patients - even years later, she personally follows up me multiple times, and is as interested in my own vision outcomes as I am. She is thorough, detail-oriented, and can confidently convey the same depth and breath of knowledge to her patients. Due to my correction being borderline for the limits of LASIK, all contingencies were planned for to ensure excellent outcomes. Even years later, I have not had a single post-op complication, including zero days of dry eyes. Dr. Zhu is an amazing eye surgeon, and more importantly, an awesome human being. I'm absolutely ecstatic about the care I've received, and cannot recommend Dr. Zhu any more highly.
