World-Class Training

Dr. Zhu is a board-certified cornea specialist and one of the few ophthalmologists in the country to have additional fellowship training in cornea and laser refractive surgery. That means she is an expert in all areas related to the anterior segment of the eye including laser and lens-based refractive surgery, cataract surgery, keratoconus treatment, corneal transplantation, and ocular surface disease. She received her M.D. from Harvard Medical School and completed her residency at Doheny Eye Institute/University of Southern California (USC). She then completed her fellowship at Bascom Palmer Eye Institute, consistently ranked the #1 eye hospital by U.S. News and World Report.

State-of-the-Art Technology

Laser vision correction has come a long way, giving you more options than ever to achieve freedom from regular glasses, reading glasses, and contact lenses. Dr. Zhu offers the most advanced, NO-CUT, laser technology in all of San Gabriel Valley, allowing you to achieve the best vision possible. She uses only premium laser technology for All-Laser LASIK and Bladeless Laser Cataract Surgery for her patients. Because of her specialized training and unique access to the latest technology, Dr. Zhu has been able to successfully treat hundreds of patients who were deemed poor surgical candidates. When it comes to your vision, you should settle for nothing but the safest and most precise technology.

From day 1 of your consultation until your postoperative visit, she is with you every step of the way in your journey to clear vision. Every patient and eyeball is unique. Dr. Zhu will use her expertise in the anterior segment of the eye to recommend the best options for you--even if that means no surgery at all.

Fluent in Spanish and Chinese, Dr. Zhu and her multilingual staff are ready to provide the highest quality care to you and your loved ones.

MEET YOUR SURGEON: DAGNY ZHU, M.D.

Dr. Zhu is a Harvard-educated, board-certified ophthalmologist who specializes in cornea, cataract, and laser refractive surgery. She was born in Shanghai, China and immigrated to the United States with her working-class parents at the age of 3. As a Southern California native, Dr. Zhu graduated top of her high school class as valedictorian and attended UCLA on a full-tuition Regents scholarship (the highest award granted in the UC system) where she graduated Summa Cum Laude with a degree in molecular, cell, and developmental biology.

Dr. Zhu received her M.D. from Harvard Medical School where she discovered her love for ophthalmology and performed cutting-edge research on corneal immunology at Harvard’s Massachusetts Eye and Ear Infirmary. As a medical student, she co-founded the Medical Mandarin course for doctors-in-training and embarked on a medical mission with Operation Burns in Mumbai, India where she worked alongside plastic surgeons to treat burn victims with debilitating skin and eyelid contractures. Dr. Zhu then returned to Southern California to complete her ophthalmology residency at the prestigious Doheny Eye Institute/University of Southern California (USC) + Los Angeles County Medical Center, where she served a predominantly Latino community and cared for the sickest patients at one of the largest public hospitals in the country. Described as a “gifted surgeon” by her mentors, Dr. Zhu elected to complete fellowship training in cornea and refractive surgery at Bascom Palmer Eye Institute, the #1 eye hospital in the world.

In addition to laser vision correction and laser cataract surgery, Dr. Zhu treats all diseases of the anterior segment including corneal transplantation, cross-linking and intacs for keratoconus, and pterygium surgery. She has published several scientific journal articles and book chapters on advanced corneal transplantation techniques, corneal endothelial disease,  infectious keratitis, and femtosecond laser technology. She is a member of the American Academy of Ophthalmology, the American Society of Cataract and Refractive Surgery, and the Cornea Society. Dr. Zhu has come full-circle and now practices as a managing partner at Hyperspeed LASIK (an NVISION company) in her hometown of Rowland Heights in the heart of San Gabriel Valley. She lectures regularly to community optometrists and is a volunteer attending at the Los Angeles County + University of Southern California Department of Ophthalmology where she teaches eye surgery to young resident doctors. She also serves as an admissions interviewer for Harvard College and provides mentorship for premedical students. Fluent in Mandarin Chinese, Shanghainese, and Spanish, Dr. Zhu is proud to serve her hometown and neighboring communities in Los Angeles, Orange County, San Bernardino, Inland Empire, and beyond. In her spare time, Dr. Zhu enjoys playing classical piano, acrylic painting, and singing karaoke.

After Cataract Surgery

"My wife and I visited Hyperspeed Lasik this past Tuesday the 15th to do a follow up for a surgery that we had. The staff was very friendly, professional and attentive especially Evelyn Magadan. Since we had the surgery she explained the process in detail and addressed our concerns going in. She has been taking care of us every step of the way in our recovery. Evelyn and Dr. Zhu have done an excellent job helping us improve our vision and have treated us well. Like family. I highly recommend Dr. Zhu and Evelyn Magadan! Thank you HyperSpeed Lasik!"

After LASIK

"Yes, it really is life changing, and I can't begin to describe how wonderful it is to be able to wake up in the middle of the night and see the time without getting up...Dr. Zhu is very energetic and cares to spend time answering patient questions - not only to make sure the patient is comfortable, but to also make sure that you get the best result possible. To top that, she's trilingual and it was really impressive hearing her converse to patients in multiple languages... All the other patients (and relatives of patients) I talked to were really happy with both the care she took with the procedure and the results!...In short, Hyperspeed offers a level of service, care and attention that I doubt the other big vision centers could provide.

Intacs for keratoconus

"I was diagnosed with keratoconus and I was recommended to this center and I'm so grateful that I was. It was very scary when I found out but when I got there the whole staff made me feel comfortable. Dr. Zhu did a great job in explaining what keratoconus is and what options I had available to treat it.
I ended up getting intacs and the surgery went well. Dr. Zhu made sure I was comfortable throughout the whole surgery and I really appreciated that because it was a very scary moment in my life. I highly recommend this place, very professional and friendly. They truly care about your health. I am still in communication with the staff there and they continue to care for my well being and answer any questions I may have.

After LASIK

"I absolutely do not regret my decision to get LASIK surgery and I'm especially glad that I went to HyperSpeed LASIK! I had Dr. Dagny Zhu perform my surgery and she was so careful with me. She's so cheerful and will answer any questions you have. She also has amazing credentials (UCLA, Harvard medical school, USC for residency, and did her fellowship at the #1 eye hospital in the world- Bascom Palmer). My healing process was so quick and painless; no discomfort whatsoever! I know everyone heals differently but I feel like a part of it also has to do with how the surgery was performed itself and the machine used. The laser they use is one of the newest lasers that does not use a blade... I'm honestly so grateful to have gone here! The entire staff gave the best level of care I've ever experienced...My friends and family can see the happiness i have from this that they're even considering getting it done at Hyperspeed LASIK! I can't explain the amazing feeling of waking up and being able to see!

After LASIK

If you are seeking help to better your vision THIS IS THE PLACE!! I have had horrible vision for the past 5 years and with the help of Hyperspeed LASIK I was able to see 20/20 just an hour after my procedure!!!! I was amazed at the results and had such a wonderful and friendly surgery! Dr. Zhu and her assistants did an amazing job walking me through my procedure and very patient answering all my questions and helping me with every detail I needed to know to care for my new eyesight. Evelyn Magadan (Habla Espanol) was my financial counselor and I couldn't thank her enough for helping me find a financial way to afford my procedure. She is also bilingual which helped very much inform my parents about my procedure as well. I am very happy I walked into this place I can now enjoy my days and nights out! Thank you Hyperspeed LASIK center!!!

After LASIK

Best decision ever.

Want to give yourself a gift? I high recommend getting LASIK. It will change your life. Had a great experience with Hyperspeed LASIK and would highly recommend to anyone...Dr. Zhu is extremely meticulous and thorough! During the consultation, I wasn't a good candidate for LASIK due to dry eyes and was recommended for E-LASIK or LASEK. However, after running multiple tests, Dr. Zhu cleared me for LASIK, which has a shorter recovery. Having all the tests ran multiple tims and knowing that Dr. Zhu looked through my charts thoroughly made me feel more comfortable to go through with this procedure. Her staff is also helpful and friendly. Thank you!!

After LASIK

Dr. Zhu and her staff are amazing. Got LASIK done about 3 weeks ago and it was the best decision I have ever made for my eyes. The staff is very friendly, from the moment you walk in, they treat you like family. I had really bad eyesight and astigmatism so I couldn't see without my glasses and now after surgery I see 20/20. I couldn't believe I was able to see without glasses. I recommend this place to anyone thinking about getting LASIK!
