David F Chang, MD

Had both eyes done by Dr Chang. EXCELLENT! An expert in his field… his office staff are very professional and competent. Recommend him to anyone having cataracts removed.

I did my homework before settling on Dr. Chang. He got the most referrals from my friends. Dr. Chang was also the doctor who found out the association of a prostate medicine Flomax and its effect upon some defects (iris flapping) of cataract surgery. If you are taking Flomax and in need of cataract surgery make sure you ask the surgeon (s) if they know the side effects of the medicine.

I was referred to Dr Chang by my regular eye doctor — he replaced both cataracts with UV lenses and fixed the astigmatism in my right eye. I’m ²⁰⁄₂₀ in that eye now. Very efficient organization, never have to wait long. The eye surgery center staff is fantastic. Can’t recommend him highly enough.

The uItimate eye surgery experience, if you have to have it done. I had a bad experience with RK surgery in 1992 which caused my eyesight to go from being nearsighted to farsighted with a lot of astigmatism requiring me to wear contacts to be able to have adequate vision. Finally in 2012 my cataracts became significant enough that I needed and qualified for cataract surgery.
In April I had cataract surgery on the left eye & couple of months later the right eye by Dr. Chang. He was very candid with me about the issues that the RK causes and what results I could expect from the surgery. Over the next several months to my suprise my eyes have continued to improve to the point where I can now qualify for a drivers license without glasses and I can read without glasses/​contacts which I couldn’t do since the RK surgery 20 years ago. The surgery has exceded anyexpecations/​thoughts I had on how good my vision would improve. I can see colors better and in low light conditions, which when you are in your seventies becomes an issue. If you have had eye surgery like RK or Lasik and need cataract surgery you should have Dr. Chang at the top of your list to see.
His office operation and staff are A+ and the supporting O.D. I had been assigned to Dr. Sheri Yamanishi is the best an extremely patient with someone with the obstacles the surgery had to overcome.
The Peninsula Eye Surgery Center where the actual surgery was done is one heck of an efficient operation from the moment you arrive, to your departure less than two hours later.

Dr. Chang and his staff are awesome. My mom has been dealing with cataracts and pretty much been blind for the last 12 months. We saw Dr. Chang and recognizing how bad her eyes were he got her in right away and now she has vision in one eye, and one more to go in a few weeks. Surgery was quick efficient and she was able to see after surgery for the first time in over a year. She is very happy and we highly recommend this office.

I wanted to send out this Unilocal for a recent cataract surgery I had done with Dr. David F. Chang. I am so excited since having my right eye surgery done on Thursday 11÷15÷12. From the time I entered the Peninsula Eye Surgery Center, meeting with the receptionist then getting prepped for the OR with the nursing staff, simply put incredible. Then going in for my actual procedure the anesthesiologist made sure I was comfortable and then Dr. Chang came in and did his thing. The procedure itself i did not feel a thing. You have to keep your eye opened the entire time and that at first seemed a little overwhelming but all the worry and anxiousness prior to the surgery went away. I would highly recommend Dr. Chang for anyone considering cataract surgery, I was actually referred by a friend of a friend who had both eyes done within a couple months apart. They are state of the art and very professional, courteous and a super group of people. Kudo’s to the nurses also who attended to me before and after the procedure. Thank you Dr. Chang for changing my life and enabling me to see for the first time in a long time, street signs, beautiful array of colors in the trees and flowers. The world is beautiful to look at. Wow! The cloud has been lifted and now I can see things in a totally different perspective. If and when the time comes to have my left eye done, I know where i will be going!

I have just completed having cataract surgery on both of my eyes and could not be more pleased with the results. I can drive, read a menu, recipe and price tag all without glasses. Dr. Chang is such a wonderful doctor. On his website there is a video about what you can expect during surgery. He has also written a book that covers every detail about cataract surgery.
He is a first class Doctor who totally cares about his patients. He has a team of employees who are great as well.
Thank you Dr. Chang for giving me my vision back.

As a 50yr old I have been dealing with an oil droplet cataract for 2+yrs. Dr Chang removed that yesterday. He is a superb Dr. I only have one good myopic eye that needed the surgery, stressful for me and massive downside risk if it went poorly. ²⁰⁄₂₅ the day after surgery. How can I put into words a review for a Dr that gave me back a quality of life that has been gone for sometime and certainly better vision overall than this myope has ever had in his lifetime. Thank you so much Dr Chang!

I am relatively young to have cataracts (at least I think so!), but developed them because of medications I must take. My optometrist referred me to Dr. Chang for consultation and possible surgery. I’m a healthcare professional (master’s degree in nursing) with many years of practice, and am not easily impressed. However, I have been bowled over by my experience with Dr. Chang, his office, and Peninsula Eye Surgery Center. Everything, from the first visit to the surgery to the postop visit, went beautifully. Dr. Chang himself is world-​renowned, and his fame is certainly deserved. For the first time in years I am able to see without eyeglasses or contacts, and I’ve only had one eye done so far! I’m actually looking forward to the second surgery!

Dr. Chang recently operated on my father’s cataract and everything went really smoothly. Any type of surgery is nerve racking but this doctor and his staff were really amazing. They make the patient and their family feel comfortable and well cared for. I would recommend them without any hesitation!

I had my cataract surgery done several years ago by Dr. Chang. He is WORLD CLASS all the way! He performs the surgeries at Penninsula Eye Surgery Center on El Camino in Mountain View. Both Dr. Chang and the surgery center can’t be beat. The personnel in the surgery center are well trained, efficient, up-​beat, and strive to make this a fear-​free and pleasant experience for you. Dr Chang specializes in cataract surgery so if you want the best, you’ve found him with Dr. Chang. I would highly recommend Dr. Chang and the Penninsula Eye Surgery Center to anyone. I was in and out so quickly, and feeling so good, I went straight to the rib joint for lunch.

I had a difficult situation with one eye with a cataract that was a result of a racquetball accident from years ago.
I discovered that Dr Chang is a cataract specialist that teaches, works for with the FDA for work relating to new items to the market, and works on patients that had cataract surgeries with other doctors that have gone bad. He is very capable of working with difficult and not the norm situations.
If you have a cataract (s), he is your man! I traveled a long distance for his services because he is that good.
Check out his website just learn more about cataracts. There is a good video on there, plus you can learn more about Chang.
Btw, I used Dr. Sheri Yamanishi thats in his office for my contact prescription. I asked a million questions and answered them all even though she had patients waiting. Her associate checked on us twice because she was actually taking her time with me answering all of my many contact lens questions from differences in brands to different materials to what happens when you sleep with your contacts. She was GREAT! I am loyal to her now even though she is far from me. Dr. Yamanishi totally inspected my eye and told me exactly what she saw in my eye and her concerns — Corneal neovascularization. I sleep with contacts — not good.
I walked out of the office with 3 different prescriptions (3 different types of lenses) so that I could test out which one I felt most comfort with and then order my boxes after I figured out which ones were best for me! Loved her.

Dr. Chang is the undisputed cataract king! I had a trauma cataract in my right eye, as a result of a tennis ball injury. The surgery was tricky since I had just completed retina surgery, to fix a retina tear. With the volume of surgeries Dr Chang does weekly, he assured me that he was averaging one trauma cataract a week — that experience was very reassuring. He provides lot of handouts and CD-​ROM, explaining the cataract procedure in detail. Since he does a LOT of surgeries, he cannot and does not spend a lot of time with you answering your every question. But that is a small trade-​off when you are getting treatment from the king! And he takes the extra effort to work with your insurance company so the resulting cost to you is reasonable.
My cataract surgery was in 2007 and I am grateful to him for good vision.

Dr. Chang is the safest bet for cataracts — and his web site has a lot of info.
My husband’s ophthalmologist said his cataracts had got to the point of benefiting from surgery, and he was ready to operate whenever my husband was ready. Just to be cautious, we looked for a second opinion from someone recognized as an expert in cataract surgery, and Dr. Chang’s name stood out.
Lucky we checked, as Dr. Chang said surgery might not help much as my husband has a more serious eye disease that needs evaluation first because the eye disease will eventually require surgery, and if cataract surgery isn’t done in a particular way, the later surgery won’t be successful. Now we’re connected with a specialist in this eye disease, but are so grateful to Dr. Chang for getting us on the right track, as the outcome could be the difference between seeing and being blind.
The first ophthalmologist completely missed the eye disease, and if he’d done the cataract surgery it would probably have ruined my husband’s chances with the surgery he’ll need in the future in order to see. The kicker is, now I’m looking at the two bills — the first ophthalmologist’s exam bill was almost twice Dr. Chang’s! So apparently world class doesn’t mean high bills.

I couldn’t put into words how wonderful Dr. David Chang is, as far as who he is and how knowledgeable he is, so I’m going to provide you with a quote from his website, «David F. Chang, M.D. is widely considered one of the top cataract surgeons in the world. He graduated Summa Cum Laude from Harvard College and earned his Medical Degree from Harvard Medical School. He completed his ophthalmology residency at the University of California, San Francisco, where he is currently Clinical Professor of Ophthalmology. He has taught cataract surgery to ophthalmology residents in training for more than 25 years. Dr. Chang is also an adjunct clinical professor of ophthalmology at the Chinese University in Hong Kong, one of the leading academic ophthalmology centers in Asia.»
From a personal standpoint, I was referred to a different ophthalmologist from my optometrist to have a cataract removed. This doctor encouraged me to get a multi-​focal lens implanted into my eye because it was his opinion that I would be able to see distance and close with a Restor lens, rather than with a regular lens. Although the Restor lens was an extra $ 2400 out of pocket expense, I chose to go that route because I felt I was worth it to be able to see both distance and close. This doctor also does Lasik procedures on patients, and according to Dr. Chang, he teaches doctors that if a patient has had a prior Lasik procedure done, they are not a candidate for a multi-​focal lens. Lasik changes the shape of the cornea of your eye, and a multi-​focal lens does not work well on a previous Lasik patient. This doctor knew that I had Lasik surgery ten years prior to cataract surgery. After having the Restor lens implanted into my eye, I could not see well at all. The «halos» at night were more like fireworks! I couldn’t even read street signs. My vision was better before the surgery than after the surgery. After many months of stress, frustration, and getting different opinions from different doctors, I decided to have the Restor lens removed and replaced.
I went to see Dr. Furlong and asked him if he would do the second surgery, since I no longer trusted the other doctor. He was kind enough to refer me to Dr. Chang because he said he is the best cataract surgeon around for difficult cases like mine. Dr. Chang told me that the taking out of a previous lens and replacing it is not an easy procedure, but he has the latest technology and equipment, developed by Nassau, where he could actually see how I see out of my eyes, which enabled him to make the decision in how to proceed. He performed surgery on me four months after my first surgery, and now I can see again! I couldn’t be happier! His staff is also friendly, and they all take the time needed to make you feel at ease. I highly recommend Dr. Chang!

HEADLINE: If you need eye surgery beyond LASIK, come to Dr. Chang!
I went to Dr. Scott Hyver hoping that he could fix my right eye’s prescription with Wavefront LASIK. After his thorough examination, he advised me that I wasn’t a candidate for LASIK, but that the root of my vision problem was actually a cataract!!!
He referred me to a Dr. David Chang in Los Altos as a highly reputable cataract surgeon, and am I ever glad he did!!!
It took 4 – 5 weeks to get my consult scheduled, but after a very thorough two hour exam, it was indeed confirmed that my right eye had a cataract, and he spent a good half hour with me personally going through the various lens alternatives for my individual needs and life style.
Being an avid competitive tennis player, especially in evenings under the lights, I wanted to be able to optimize my vision for long and intermediate distances. If I could have that, I’d be happy to have to deal with reading glasses for up close vision.
Based upon this, he recommended the Cyrstalens implant which actually has a design to let it flex slightly … just like your natural lens does. The lens enables the eye’s natural focusing muscles to cause some flexing and movement of the lens, thereby adjusting the focus.
Now this particular lens is not covered entirely by insurance like the monofocal lenses, but I thought … what the hell, I’m worth the extra money.
Long story short, I had my procedure yesterday, went in for post-​op review first thing this morning, and raced through all the eye charts top to bottom … absolutely freakin’ amazing in terms of being able to do this, less that 24 hours after the operation. Before the procedure, I couldn’t even read the first chart!!!
I’m sure, I’ll update this again in a few weeks, but I am ecstatic over my results in the very short term.
In addition to the lens replacement, Dr. Chang also took the opportunity to correct an astigmatism with some laser ablation at the same time … I’m sure that has helped with my results as well …
Harvard-​educated, Clinical Professor of Opthamology at UCSF, copious awards and achievement certificates on his office wall, very professional … excellent explanations and disclaimers of what to expect … 24 hours in, and I’m absolutely delighted with the results.
And, let’s face it, these are my eyes!!! … I honestly can’t think of anything as important from a lifestyle perspective to take care of.
I would recommend Dr. Chang wholeheartedly if you or a relative needs help in this area … unequivocally.
Thanks Dr. Chang!!!

Dr. David F Chang is truly amazing! He is a clinical Professor of Ophthalmology at UCSF. He is a graduate of Harvard College and Harvard Medical School and completed his residency at the University of California, San Francisco.
My experience was truly amazing. The staff on 762 Altos Oaks Drive is professional, friendly and on the ball. It is run like a well oiled machine.
I just recently completed having my 2 eyes implanted with multi-​focal lens. It was done at the Penninsula Eye Surgery Center on El Camino in Mountain View. The staff there was absolutely as close to perfection and you can imagine.
For those how haven’t heard about this procedure, it is an lens implant that is permanent. It is based on computer calculations and hopefully will decrease your dependence on glasses for us older citizens.
I had been to 2 other Dr.‘s and no one had suggested this procedure.
Dr. Chang does more of these than any other Dr. in the state of California.
It was a 4 star experience and I would recommend Dr. Chang and his staff very highly. I just read about him on the internet and I thought his resume spoke for itself.
Bravo Dr. Chang and staff. You are as professional as professional can get. And no, I am not getting paid for my review.
Everyone needs a compliment, not a criticism and I am glad to pass it on.

Dr. Chang operated on my grandmother’s cataracts years ago. He is THE cataract surgeon around here.
He’s super nice, too. We used to get regular check ups from him like, 10 years ago but then he started only specializing in cataract surgery. Sad.

If you know of anyone needing cataract surgery, Dr Chang is THE MAN. check him out. He was great with my dad, took 2 months to get an appointment but worth the wait.
