    This is very lengthy, but I am Sooo passionate about this that I do not want anyone else to have this kind of bad experience. I would give Barack a minus one If I could.. I also plan on letting the medical board know how unethical and non caring Dr Mark Barack is. He was my doctor when his practice was on Foothill in Pomona Ca. I first met him in the 90's when he let me know that Doctor Mousa's Mono Vision was a wrong choice for me because Mousa took away my distant dominant eye and brought it so I could only read with it therefore I could not see for over three months until my brain accepted this change. Fast forwarding, now I need cataract surgery. I gave Barack my total trust. I now find out he also suggest PanOptic lens to EVERYONE who needs cataract surgery instead of giving us other choice of lens which would be according to each persons eye needs. If a person already has astigmatism/halos. PanOptics is NOT the lens to have. A muti focal lens should never be placed when astigmatism or halos are seen because it will creat more halos. So I walked into Pomona Valley Hospital nervous but totally trusting Barack. Two years later and my vision is WORSE than before surgery. I could not drive especially at night because of how blurry my vision is and still is. Before moving I went to Baracks office several times and waited for almost two hours before being seen just to get an arrogant, "sue me if you want" answer from him. He was willing to perform a corrective PRK which takes three to four months to heal and much pain involved.That's not a solution especially when I was moving out of state, which he was aware. Why would I trust him the second time when he left me with blurry vision and worse halos. than before the cataract surgery. Doctor Chuck from Pomona and Doctor Lee from City of Industry in Ca and two doctors in Arizona, Doctor Patrick Aiello and Doctor Nappi from Scottsdale have since confirmed what a horrible mess Barack left me in. I asked Barack to refund my $2,800.so that I can have it corrected with LASIK but Barack refused. His comment was, he will refund IF I give him back his PanOptic lens. WHY? So he can reuse it? How tacky and unethical.

    Ummmm who's that's sexy deep voiced man that I heard the back?? Holy smokes. They say a woman falls…read morein love with what she hears...but no worries! Meagan helped me fall in love with what I see--because for the first time, I could actually see! I'm serious. I saw Dr. Ishi, who I seriously cannot recommend enough -- she's truly amazing. She helped me figure out that my previous experience at Costco Optical has, in fact, been totally useless and wholly inaccurate--my prescription has been off for like...10 years??? No wonder I can't see at night! Ha ha! Turns out, my bizarre and highly astigmatismed eyeballs happen to be both nearsighted and farsighted on each respective side..and thus require a certain amount of due diligence and attention--all of which I have never experienced at any other optometrist prior to coming to this place. Literally, one side of my contact prescription was off by 1.5 points or whatever they use to measure it--i mean, what?? Should I contact my car insurance to dispute any claim against any minor car accidents that I may or may not have been involved in over the past DECADE since I LITERALLY COULDN'T SEE!!!?? Dr. Ishi is incredible. Megan is a sweetheart who helped me pick glasses that not only fit, but ~*flattered*~ my large and in charge face. Because of this wonderful team, I can FINALLY see for the first time in my life. Can't recommend this place enough! 10/10. Ps; and not to be super creepy or anything...as I still don't know that deep and mysterious voice I heard but I think I'm low key in love. I seriously can't wait to go back!! But next time, I think I'll wear makeup! Although idk maybe i won't bc what if they put drops in my eye and my mascara runs??? Only time will tell...stand by for updates ).

    Today I visited Spectrum Eyecare for the first time and it was an appointment booked about 2 to 3…read moreweeks ago. The receptionist Riley, the technician April, the optometrist Dr. Ishii and the optician Megan were all very nice and patient. These ladies including the optometrist are very professional, respectful and knowledgeable. They all did a fantastic job helping me. The process was very smooth and took less than an hour. The visit was a pleasant experience and I wish I had come here for glasses earlier. I can't wait to have my new pair of glasses from Spectrum Eyecare. I was told it's going to take around 3 weeks. It's the holiday season now so it's understandable that it's taking longer than usual. I recommend Spectrum Eyecare to anyone who needs an eye doctor and glasses Updated Jan 3 2025: Today I picked up my new glasses from Spectrum Eyecare Optometry. The glasses are beautiful and perfect! I am so happy with my new glasses and the wonderful service provided by all the staff of Spectrum Eyecare !

    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.

    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!
