Dr Maher said don't worry, and gave me a prescription for special eye drops and within 4 days my eyes were back to normal.

I was previously a patient of Dr. Phan since 2010, and Dr. Lozano took over my care in February 2026. She's extremely thorough, especially with my high‑myopia‑related issues, and the visual field and scan process was smooth and well organized. For optometry and glasses prescriptions, I see Dr. Isabella Duong, who's excellent and very patient. I've also seen Dr. Olivia Wilde here in the past with good experiences. As a long‑time patient, I've always found the staff accommodating, though the office can be busy and phone pickup can be slow -- pretty typical for a large practice. Parking is decent; the Lomita Blvd side usually has more spaces. A few improvements I'd love to see: 1. Online payments. Mailing checks or writing credit card info on paper isn't ideal, especially given past issues with mail theft in the area. 2. More waiting room space. Since the merger, both the main waiting area and dilation area feel cramped. 3. Online scheduling and reminders. Other nearby offices already use digital forms and appointment systems, which would help avoid missed‑appointment fees. Overall, the doctors here are excellent, and modernizing a few systems would make the experience even better.

A routine checkup took around 1.5 hours! I advised my father to consider finding a more professional and efficient office going forward. The only positive part of the visit was Renee at the pink workstation during checkout. She was genuinely pleasant and helpful.

THANK YOU DR. TAN for saving me from going blind. I can't thank him enough for his kindness and…read moremagical surgical skill! Thank you! Dr. Tan is hands down the best ophthalmologist in LA. I was referred to him as an emergency case by my general ophthalmologist due to my sudden visual lost/ retinal detachment. I've been going to several ophthalmologists for the past couple days but none of them was able to help:( He was the one doctor who was on call that weekend luckily(apparently Retina Vitreous Group is the most reputable and biggest retina group in LA county and there are 11 doctors total in their huge group!!) He returned my ophthalmologist's call immediately, took over my case and saw me right away in his downtown office. He did surgery and got my vision back! It is horrifying that so many eye surgeons were not able to figure out my issue until I was referred to him. I wish there were more doctors like him who genuinely cares about patients' health and EYES! Thank you again Dr. Tan!!!!

Like the other reviews, Dr. Tan and his office in Torrance (he has 2!) is exceptional, bar none…read more That's right, I know the Torrance medical community well. First the office is well-staffed with professionals who enjoy their work! Extremely organized and competent; better yet, great attitudes! Therefore, they serve many patients at a time, in a relaxed and methodical manner! So, your appointment moves along smoothly without delay!! Amazing, isn't it! Most importantly, Dr. Tan is an accomplished physician. I had to ask: yes, he's a USC Fellow and "teaching physician", conducting periodic professional discussion and review. His time with you is unhurried, delivering your diagnosis as if a consulting friend, realistic and practical. You get the straight scoop, no exaggeration, no magic meds, or program to fix the un-fixable. So, we get to watch my condition over time. I'm OK with that.

My name is Kemp Massengill, MD, and my medical background is that of a practicing Eye Surgeon for…read more25 years specializing only in cataract and lens implant surgery. As a senior citizen, I developed cataracts myself and needed to select an Eye Surgeon for my own visual rehabilitation requirements. Having practiced cataract and lens implant surgery for decades in Southern California, I personally know many qualified Eye Surgeons who would operate on my eyes and do a nice job. What I was looking for, however, was not only an Eye Surgeon with outstanding surgical talent - but also an Eye Surgeon who treats patients with genuine caring and respect, as I did for my own cataract and lens implant surgery patients. I found this Eye Surgeon - Patrick Yeh, MD. Doctor Yeh was referred by my wife's Family Doctor at UCLA Health, even though Doctor Yeh was in the Torrance (Cedars Sinai) group, rather than UCLA. Patrick Yeh, MD, is the most conscientious Eye Surgeon I have personally met, and now I have had both cataracts removed - AND I AM DELIGHTED! Doctor Yeh's practice is NOT a Medicare-cataract surgery mill - with such doctors churning through 80-100 patients a day. In my opinion, it is impossible to be truly thorough in these high-volume situations. Doctor Yeh's practice is medium-sized, and it is obvious that he likes it that way - as then he can thoroughly examine each patient, using not only his excellent medical/surgical skills, but using the very latest in ocular test equipment. I believe that in my own cataract and lens implant surgical practice that I was the most thorough surgeon I know (please don't take this as arrogance: patients told me this over and over) - but Doctor Yeh is even more thorough even than I was. This is very impressive to me, and I cannot overstate how very fortunate I am that I chose Doctor Yeh. Also, there is no such thing as cataract and lens implant surgery being a 'simple' procedure. This is marketing 'hype' to lure patients in the door. This is NOT a 'simple' procedure, and serious complications can occur, although it is not lengthy surgery, such as a heart transplant would be. Also again, many patients have co-existing retinal problems, such as macular degeneration, retinal wrinkling, macular edema, branch vein or branch artery occlusions, and other problems, such as glaucoma, which limit the final vision, even with perfectly executed small-incision cataract and lens implant surgery. Patients are sometimes in denial regarding what are called co-morbidities. And retinal problems are difficult to diagnose in advance of cataract surgery - because the view of the retina (the back of the eye) is obscured by the cloudiness of the cataract in front of the retina. It is like looking through a foggy windshield and trying to clearly read distant signs. In fact, denial is a normal human trait. For instance: Why would someone who has had a coronary bypass procedure and a bad heart frequently eat a double cheeseburger with extra bacon and extra cheese? Or 3 doughnuts? The reason can only be denial of the damage from this diet (tasty as it is!). Again, it is a normal human trait to be in denial of risk. And it has been demonstrated over and over - such as in very compelling videotaped risk discussions of patients undergoing very serious, life-threatening, heart surgery - that after the surgery, many patients will be adamant that the risks were never discussed. When shown the videotape of such discussions of risks, they are truly amazed, as they had complete amnesia for ANY discussion of risks. I myself have a little wrinkling of my left retina, and this affects my vision a little bit - again, because of my retinal pathology. The cataract surgery did not cause this! In summary, the cataracts are gone, and the surgery performed by Doctor Yeh was absolutely pristine! Doctor Patrick Yeh truly knows what he is doing, and is a very caring and deeply concerned human being (in a world where caring is all too often a missing ingredient). And if I you wish to discuss any of this with me, please send me an email to kemp.massengill@gmail.com, and be sure to put on the subject line : Regarding Patrick Yeh, MD. AS A CATARACT/LENS IMPLANT SURGEON MYSELF, I GIVE PATRICK YEH, MD, THE VERY HIGHEST 5-STAR RATING POSSIBLE. THANK YOU, DOCTOR YEH!!
