Dr. Zhu is a Harvard-trained, board-certified eye specialist in cornea, cataract, and refractive surgery. As a key opinion leader in advanced laser vision correction, cataract, and custom lens replacement surgery, Dr. Zhu educates surgeons from around the world on the latest surgical procedures and serves as medical advisor to multiple ophthalmic companies. She leads FDA clinical research trials on the latest advancements in cataract, refractive, presbyopia, and keratoconus treatments. Dr. Zhu has delivered and been featured in over 300 lectures, scientific presentations, publications, and press articles including Forbes, the Today Show, InStyle, and CNN.
Dr. Zhu practices as Medical Director and Partner of NVISION Eye Centers in Rowland Heights, CA. As a first-generation immigrant, she graduated as high school Valedictorian and Summa Cum Laude from UCLA on a full tuition Regent’s Scholarship and went on to receive her M.D. from Harvard Medical School. She did her residency at the prestigious Doheny Eye Institute/University of Southern California (USC) and completed her cornea and refractive fellowship at Bascom Palmer Eye Institute, consistently ranked the #1 eye hospital in the country.
Advanced Premium Technology
Laser vision correction and custom intraocular lens procedures have come a long way. Dr. Zhu uses only the saftest, most-advanced laser technology available today including the LENSAR femtosecond laser for bladeless laser-assisted cataract surgery as well as the Zeimer femtosecond laser and Allegretto Ex500 excimer laser for custom Contoura® topography-guided LASIK. With custom LASIK, patients can often achieve better than 20/20 vision with improved nighttime driving vision compared to their glasses and contact lenses.
Dr. Zhu is on the forefront of technological advances and was the first surgeon in Los Angeles to implant the PanOptix® trifocal intraocular lens to help patients over 45 years of age achieve freedom from glasses for near and far with a custom lens replacement. She was also one of the first surgeons in the country to implant the EVO® ICL, an implantable collamer lens that corrects high levels of nearsightedness and astigmatism in patients who are not good candidates for LASIK or other laser vision correction procedures.
Trustworthy Care
Dr. Zhu has performed over 20,000+ successful procedures on fellow physicians, community leaders, and celebrity influencers. She will treat you like her own family. Every person and eyeball is unique; Dr. Zhu will use her expertise to choose the right procedure for you, even if that means no surgery at all! Fortunately, Dr. Zhu has been able to offer treatments to hundreds of patients who have been deemed poor surgical candidates elsewhere.
Unlike a traditional "LASIK-mill" where patients are often treated as a "number," Dr. Zhu and her team are with you every step of the way in your journey to clear vision. From your no-cost consultation to your surgery day and beyond, Dr. Zhu's team will ensure all your questions and concerns are addressed as customer service is our number one priority (Just check out our 5-star yelp reviews!) We know that vision correction surgery is a huge once-in-a-lifetime decision, and we are here to make your experience as smooth as possible.
MEET YOUR SURGEON: DR. DAGNY ZHU, MD
Dr. Zhu 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.
"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!

20/20 after LASIK
Dr. Dagny Zhu runs an incredible operation at HyperSpeed LASIK - NVISION Rowland Heights. I never thought I'd find myself writing a review for a surgery, but here we are. I'm currently early in my dental career - seeing and treating dental patients daily. To say my vision is critical, is an understatement, so I knew I would only be trusting my eyes to the best. After a lifetime of contact lenses and glasses correction, I knew it was time to get it laser corrected and be done with it. 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. 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 does not go unnoticed in my book.
Non-academically, Dr. Zhu herself is incredibly personable, and shows an unwavering commitment to her patients - she's personally followed up with multiple times, and is clearly just as interested in my own vision outcomes as I am. Dr. Zhu is thorough to say the least, and leaves no stone unturned in diagnosis and treatment planning (and this has been true at every appointment - pre-op, post-op and surgery day itself). This level of attention to detail is directly attributable to my vision (which was a significant prescription) being easily correctable and largely healed within days of surgery.
The entire team went out of their way to ensure that appointments were scheduled at my convenience (or rather, the complex schedule of anyone working in Medicine), and were accommodating through out for last minute changes, coordinating payment and benefits, and the whole experience. I'm on a first name basis with much of the staff, and they've have turned into a challenge amongst themselves to see who can pronounce my last name correctly (it's not easy, but they're rocking it!).
Dr. Zhu is a great eye surgeon, and an awesome human being. I'm absolutely ecstatic about the care I've received, and cannot recommend Dr. Zhu and her team any more highly.

20/20 After EVO ICL
I just had my life-changing eye surgery with Dr. Dagny Zhu at HyperSpeed LASIK. She recommended an implantable EVO ICL™ Lens over LASIK because of my high (-9!) prescription and the experience has just been absolutely amazing! The surgery was painless and recovery better than expected. In fact, I was already seeing 20/20 the next day! This was by far one of the best decisions I have made, I only wish I knew Dr. Zhu and had the surgery sooner. My work as a radiologist has never been better since my dry eyes from wearing contacts and eye strain from wearing glasses have all been eliminated. Thanks again Dr. Zhu for the impressive work that you do!
