Reviews from Our Patients

Personable, friendly staff, and a warm environment. All of the staff is very knowledgeable in their respective domain of expertise. My eye tests were administered smoothly and timely and of course my eye exam and consultation with Dr. Quon was superb! As always Dr. Quon is personable and provides information in a manner in which the patient can comprehend. Bob was attentive as always when helping me to select my prescription sunglasses and my prescription eyewear. Bob's in-depth knowledge about eye lens, framing, and specific protections that are needed for prescription eyewear, is always very helpful in making the best selection for the need and the look.

My family has used Dr. Quon for over 10 years. We drive a considerable distance because he's the best--both he and his staff take better care of us than any other eye doctor we've had. He educates and proactively informs us and takes time to really partner with us for outstanding eye care .

Amazing doctors, Amazing knowledge and patience, Amazing staff: Dr's Quon and Yoo represent doctors with a great bedside manner and desire to help each patient- one at a time, and make each one feel as they are the practice's only patient. I've been coming to South Coast Optometry pretty much since their inception a longggggggggggggggg time ago. It may be 20 years. I have a complex eye situation and have worn glasses/contacts since age 3. Recently Dr. Quon diagnosed me with a second cataract and is working with me to get that taken care of. He and Doctor Yoo go out of their way to serve their patients. All I know is since I found South Coast Optometry my eyes have never been under better care. Dr's Quon and Yoo are connected to the top ophthalmic specialists. The staff of Sheila, Bob, Rachel, Nikki, Lesley and the past including Yumei and Karen were/are phenomenal in helping coordinate RXs, insurance, eye health protocol and of course new lenses (contacts or eye glasses). FYI, SCO only carries the latest technology in eyeware and RX scripts. The doctors are constantly staying on top of the latest technologies to manage prolonged vision health. I can't recommend SCO enough. They get the highest marks from me and the practice's other discriminating patients, across the board! Thanks Dr's Quon and Yoo!!

Scleral Lenses for Keratoconus in Costa Mesa, California

Have you been diagnosed with keratoconus or another corneal disease? You may not need a corneal transplant, consider non-invasive therapy alternatives like a scleral lens. Scleral lenses are an ideal solution because they sit on the sclera without ever touching the cornea, giving sharp, clear, comfortable vision.

Dr. David Yoo & Dr. Daniel Quon at the Specialty Contact Lens Center at South Coast Optometry can treat your keratoconus.
