    12/7/2024 12/7/2024 The purpose of this review is sincerely express my belated appreciation and gratitude for the excellent care I have received from Dr.Grant Lee at Cornerstone Eye Center in Rowland Heights more than ten years. In any hospital or Doctor's office, one can expects competent care, clean area, good quality treatments, and patient centered service. I have received all but more. Since I first met Dr. Lee in his Rowland Heights office more than ten years ago, he has continued to make efforts to pay attention to my concerns and questions and unfailingly execute his "patient first belief." First, one of the main reasons to see Dr. Lee was unusual eye floaters in which spots in vision that looked like black or gray specks that drift across the both eyes, and a light flash in both eyes which lead visual disturbance. He listened patiently and carefully to my concerns and provided concise, precise answers to my questions. He emphasized that my floaters and flash will eventually go away as it is treated by medication and time. Another symptom was mild development of glaucoma. Dr. Lee suggested that medication BRINZOLAMIDE to lower my intra ocular pressure (IOP) so that glaucoma symptoms may delay its progression. Furthermore Dr. Lee explained complex medical concepts in a way that I can understand completely. Although glaucoma is not completely curable, but there are ways to slow down its progression and protect my visions. Also, he emphasized my healthy life style, toward dry eye symptoms treatment and exercise to maintain proper body weight which led reduce eye pressure. With compassion, sincerity, empathy, forthright, and respect, Dr. Lee works closely to me in collaborative way. I believe he try his best to help me navigate the pathways towards the best possible health outcomes and quality of life shared decision making throughout a decade. Second, unparalleled combination of expertise and distinguished academic background, at the core of Dr. Lee's philosophy "patient focused", I have no doubt that he was recognized by CASTLE CONNOLLY TOP DOCTORS and SUPER DOCTORS since 2016. I am glad and much honored to receive top notch doctor's treatment. (Attachment 1,2) Third, despite of busy schedule of his own, Dr. Lee educate the public, in his area to promote better eye health outcomes by sharing his medical knowledge to write an article to the journal of KOREAN NEWS by CALCOM in east Los Angeles area region. As we know such education can also lead to more accurate health beliefs and knowledge thus to provide better lifestyle choices. It empowers individual to make informed eye health decisions and most importantly improve community eye health. Here are some examples that I refer to myself. (Attachment 3,4,5) Fourth, Dr. Lee continuously upgraded state of the art medical equipment to serve better care for his patients. (Light Adjustable Lens by RxSight). Normally, new technologies can help doctor diagnose patient's conditions more accurately and treat better in early stage. I am grateful that he truly care for his patients. (Attachment 6) Fifth, I believe Doctor's referral is very import because it ensures that a patient is directed to the most appropriate specialist for their specific medical conditions. For example, years ago my wife had an eye injury while business traveling outside of California. As soon as she came back, she seek to medical attention to see Dr. Lee. After he carefully examined her eyes, Dr. Lee concluded that her symptoms were retina issues, so he immediately sent her to see DR. HEATHER CHANG in City of industry. Thanks to his rapid response and Dr. Chang's treatment, she completely cured and that she keep maintaining good eye health. Now I know Dr. Grant Lee is a great doctor not only he is master of his field of ophthalmology consistently achieves excellent outcome but adapt new technologies to serve better to customers who come to the CORNER STONE EYE CENTER. During my visit to Dr. Lee, even though I ask many questions, not one of my questions or concerns went unanswered. I believe Dr. Lee's pursuit of his profession as a doctor is noteworthy, and I hope he continues to inspire other same professionals in his field always do what is best for the patients. Sixth, I compliment his medical staff. As we know, the medical as well as office staff are crucial to quality of patient service. Despite of their busy schedule, their attitudes, demeanor, professionalism and friendliness are admirable. when it comes to their excellent medical service, Ms. Heather particularly stands out in my mind. Years ago, my computer was hacked, all stored info was wiped out, including research papers, and information regarding my financial institutions, and report of findings from my doctors. Needless to say, Dr. Lee's report of findings were gone completely. Ms. Heather helped and restored completely for reports of findings which I greatly appreciate her help even though it took more than hours. Dr. L

    So nice!

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.

    I had an outstanding experience with Dr. Dagny Zhu in Rowland Heights. From the moment I walked…read moreinto the office, the staff was friendly, efficient, and made the entire visit feel smooth and stress-free. Dr. Zhu is incredibly knowledgeable, patient, and attentive. She took the time to thoroughly explain my eye condition and walked me through all of my treatment options in a way that was easy to understand. I never felt rushed, and she answered every question with genuine care and professionalism. What really stood out was her attention to detail and how comfortable she made me feel throughout the exam. It's clear she truly cares about her patients and takes pride in delivering top-quality eye care. Her expertise and calm demeanor immediately put me at ease. If you're looking for an ophthalmologist who is skilled, compassionate, and takes the time to provide personalized care, I highly recommend Dr. Dagny Zhu. I'm grateful to have found such a trustworthy eye doctor and will definitely continue coming here for my eye care needs!

Dr. Grant Lee, MD, is by far the quintessential of Eye Physicians and best Ophthalmologist I've been treated by. His vast expertise and experience and unwaivering commitment to his patients is inspiring and unmatched by any standard. And the number and variety of degrees and certificates on his office walls are nothing short of impressive. Ms. Kim, Dr. Lee's Medical Assistant, is the top-of-the-scale in skill, knowledge, patient care, dedication, thoroughness, sincerity, attentiveness, enthusiasm, all this, while exuding an 'above-and-beyond' attitude in her personality and work ethics. Dr. Lee's entire staff are friendly, patient, prompt, organized, success-driven, highly trained, extremely professional, blessed with unceasing exceptionalism, while displaying superior people skills and excellent communication skills that are well beyond merely competent. Personally, as a retired supervisor for the Los Angeles Police Department, I believe the Cornerstone Eye Center in Rowland Heights is the best in the nation. My family members and friends are anxious to meet my new Eye Doctor. And from this point, I am a patient of Dr. Lee's for life!

    My eyes have always required thick lenses, which made it difficult to find certain prescribed…read moreglasses. I came here to get this corrected so I could deal with the issue. At 41, I've started to think that advancements in eye correction technology are much more promising than what has been available in the past. Surgery can be a daunting experience, especially when it involves your eyes. However, I encourage you to try the "Evo ICL" it's safe and has improved since last year. One of the best parts about this procedure is that if you're not satisfied with the results, or if a better option comes along, you can reverse the treatment. So, there's really no major risk if it doesn't work out. I qualified for the "Evo" ICL, and while I had my doubts at first, I've learned that patience is key when adjusting to a new way of seeing. Along with eye drops to aid the healing process, I found that after about three months, my eyes began to coordinate and adjust. What was once a constant dependency on glasses is now improving, and I'm starting to feel more normal without them. It's funny; I still find myself touching my face to lift imaginary glasses that no longer exist--it's just a habit! I highly recommend this option to anyone who wants to change their vision, whether it's for practical reasons, like gaming without glasses or to keep up with future technologies like AI glasses. As technology continues to advance, my previous vision issues made it difficult to enjoy some of these innovations. This procedure has truly helped me.

    It's been a month since my surgery with the SMILE procedure and I almost still can't believe at how…read moresmooth the process went and the vision I now have. From my first visit to the office which was the same day as my consultation things ran smoothly. My next visit to the office was the day of the surgery and everything I read on yelp and online about the surgery and recovery process was pretty true to form. The follow up went smoothly as well. My only issue is actually with the cost of the procedure. Now, it is important to note that I only got a pair of eyeballs and if I'm going to have some lasers open up some slits to my corneas, then I want to go somewhere I can trust and am willing to pay more for higher quality. I was quoted at a price which I thought was fair. At this point I referenced a Groupon that was available from their Riverside office. Minutes later, I was given a different price that matched the Groupon but had a slightly higher price since it was SMILE versus LASIK. This was good news for me as I had lowered the price of my surgery, but left a slight question in my mind as it seems like pricing can be quite arbitrary and had I not done my research before, I would have had to pay more. I thought this was something I would expect with going to a dealership to buy a car, but not something like getting a surgery. So I guess if there is a helpful tip, do your research before and there's a chance you can get the same procedure at a lower cost too.

Calling to schedule an appointment is fairly easy and quick however once you arrive it is another story. Once I arrived for my appointment a few weeks later, the lobby was full of patients, a clear sign that this location does not know how to manage scheduling efficiently. Despite arriving on time for my appointment, I waited an additional 1.5 hours before I could be seen, not a good start. During that time, I was told to do the usual eye exam screenings using the machines and I CLEARLY saw that the machine I was to use, had just been used by another patient and the employee did not even bother to clean or sanitize it prior to asking me to put my eye/face on there. I had to request for them to clean it and then they cleaned it for me. Once it was finally my turn, I was seen by Dr. Chua. He was very friendly and seemed knowledgeable, however for a doctor, he was not sanitary at all. Normally, when you examine a patient, you would wear gloves especially if you are checking their eyes and pulling up their eye lids. Dr. Chua, used his BARE HANDS to pull up my eye lids not once but multiple times! I know he's a doctor but I have no idea where his hands have been, if they have been washed or if he had just finished seeing another patient. I quickly finished up my appointment, was given a prescription, paid my copay and was told to arrange a follow up in a month which I did. Fast forward 1 month later I come back, not because I want to but because I had already seen this doctor and they had my information already and was aware of my condition. Same thing, I waited for about an hour this time, despite being arriving 10 minutes earlier than my appointment time. Saw Dr. Chua again, and again, bare hands just touching my eyes and face. Finished the follow up appointment and sent me to the front desk to pay my copay. As always this is my own personal experience, and I was willing to overlook the unsanitary procedures of handling patients the first time but having it happen again the 2nd time just showed me it wasn't an accident but a common habit or practice. I would not recommend this location and recommend you go elsewhere. Not wearing gloves and touching a patients face and eyes is definitely not okay.

Over the years my vision continued to get worse, and by the time I turned 46, driving at night had become especially difficult. I knew it was finally time to do something about it. My father, mother, and brother all recommended Hyperspeed LASIK. They had also struggled with poor vision in the past, but after their procedures here, their vision was corrected and they now see better than ever. Hearing about their experiences gave me the confidence to schedule a consultation. At my initial consultation, I was honestly nervous because my prescription was extremely high--over -12 in both eyes. However, from the moment I arrived, the doctor and staff made me feel completely at ease. They took the time to thoroughly explain my options and answered all of my questions with patience and professionalism. A few weeks later, I underwent the procedure where lenses were surgically placed in both eyes. The entire process took about 45 minutes on a Saturday afternoon, and the experience was far smoother than I expected. The next morning when I woke up, I could already see clearer than I ever have in my life. It was truly incredible. I am beyond happy with the results and extremely grateful to the doctor and staff for their expertise and care. This procedure has genuinely changed my life, and I highly recommend Hyperspeed LASIK to anyone considering vision correction.

Just walking in the front door, and the whole process. This review is solely regarding about their appointment system and customer service and the whole appointment process felt like rushed and impersonal, Dr Zhu did not even come by to meet us even though she was there, not even a peep at the door. We came here for a second opinion and also exploring our options--but it turns out the first place we went to yesterday which is IQ Laser vision (which is also down the street) is far more superior with their customer service, patient treatment and just the entire process--everyone there was top notch professional as you walked in the door. I am glad that going here in Hyperspeed Lasik validated our decision making into choosing IQ Laser vision.

After I had my PCP resend the authorization directly to them, the office then told me my insurance was not valid. As someone who works in HR and processes employee benefits, I knew this made no sense. Because I was in so much pain, I paid upfront just to see the doctor and planned to sort out the insurance later.
