It has been about eight years since my last visit due to insurance issues. As it was in the past is the same today. A very specialized place with a very professional and well trained staff. My insurance issues are gone so now I will be seeing Dr. Ko as often as I need to. Need specialized eye care this is the place to go.
In your eye clinic, the eye checking procedures in advance is perfect and sufficient, or I never experienced in other retina clinic previously, 90% work done already with your assistant.

I want to thank Dr Ko and all the staff!
All the quality doctors have left!
After treatment my vision has improved!!!👍👍😀…….thank you Dr. Ko and your friendly staff…….. …
Efficient and courteous service. Knowledgeable specialist.
Highly trained professional. Completely engages with clients.
Called to make an appointment and who assisted me over the phone was very helpful and kind!
Always Fast and straight to the point. Staff is friendly and they know what they’re doing.
The staff there always inpatient to answer any of your questions. Don’t get surprise that how frequently the front desk hanged up your phone. They were too busy to answer any of your questions and concerns. If you have another choice, Go somewhere else!
Excellent staff..
You feel like family,, not just a patient.
Everyone was very professional and nice.
I have been going to Dr. Ko for years, he is very direct and very smart. He knows what he is doing and I appreciate that. The staff is very nice and Professional. Thanks for being great.
They are prompt, professional and answer my questions.
The doctors and staff are great. Even surgery was a pleasant experience.
Got scheduled fast (same day, in fact), but I wound up spending an hour and a half waiting while I was there – in the middle of a work day. To top it off, the practice is extremely out of date with their bill payment options, requiring me to either mail my card info or give it to another person.
The folks at the Retina Institute were really freindly and helpful. The staff and doctors were just great.
I thought my right eye was going to be my big problem. After an exam it was discovered my left eye was the bigger problem. Thanks Dr. Ko.
We came here twice both times we waited at least an hour and a half before we can even get to the doctor (yes we were on time) and the dotcor is running in and out rushing thought everyone, base on this I felt like they over book with …
The staff were very friendly and my visit went well.
Does an excellent job on my eyes. They have an awesome staff
The place is very clean and beautiful easy to find. However the girls up front are completely disrespectful, they have no patience whatsoever. They are very demanding and they yell at the patients.
Dr Reiss is a great doctor. He is dedicated, sincere, and caring. RIW is a great facility, and the staff is wonderful.
He is an excellent doctor and an excellent person, I highly recommend him.
I was referred to this place by my regular eye doctor and called to make an appointment. Before setting up anything, I asked how much this would cost since I’d be paying cash. The person on the phone said she couldn’t tell me. She went on …
I have been going to clinic for a long time. I have seen multiple doctors and they are all great. When I first started going- it was a serious injury, but after surgery, my eyes are doing amazing. Doctors took such good care of me, even doing my surgery late at night same day because it couldn’t wait. Much appreciated!
Been taking my Mom to Dr. KO For years and now iam a patient and love Dr. Ko and his staff.
I feel so fortunate for having been referred to Dr. Ko. I can hardly believe how painless having an injection in the eye can be and the prompt and efficient treatment I get in this office.
The doctors are great but the front desk receptionists (2 separate occasions) are just horrible with bad patient, customer skills. They are not trained to provide services to diverse populations and simply lack empathy, basic tenets of …
Horrible and the worst place to get an medical service. My daughter had 3:50pm appointment and we checked in at 3:30pm. We are still here at 6pm waiting to see the doctor. Avoid this place unless you really love wasting 3 hours for a simple eye check up. There must take fewer patients if they can’t handle.
Retina Institute in Renton has been great. I have been going every month since April 2021 for treatment. I was referred to them by my optometrist when I suddenly had vision in my left eye become entirely blurry. This obviously caused me …
Was referred to the Retina Institute by my eye Doctor for a retina separation and was quickly seen by Dr. Reiss and promptly scheduled for a necessary surgery. Surgery was performed by Dr. Mandiga and the staff at Valley Medical and Dr. …
My husband & I have been continuously impressed with the excellence of the doctors, staff & services at the Retina Institute.
Dr. Reiss and the Retina Institute are great! The doctors and staffs provide professional service and promptly answer any questions I had about my condition. The surgery went as well as I had hope for. Thank you.
Dr. Mandiga is the best! He is very patient with our questions and explains things to us. I don’t feel rushed at all during my appointment. Everyone who has been a part of my treatments (4 so far) has been friendly and professional. They make me feel at ease and well cared for. I appreciate all they are doing to help my eye!
Everyone is a profesional there. They have a very high concept of customer service. They were quick, professionals and get it done right. Love this place.
Dr Fung was patient, answered all my questions, and to my knowledge, my surgery was a success.
Dr Ko is Awesome very Professional. Dr. Ko has no problem answering questions you may have. The staff is very Professional. The young lady at the front desk called me a yellow cab, which was greatly apricated.
.
I have been seen Dr Mandiga since he started here in the Northwest. He is absolutely the best in every way, personally, and professionally. He is efficient and very thorough, and I always feel I am well taken care of. because of his expert care.
Overall, treated well by staff and doctor. Diagnosed eye injury and promptly treated it. Six months later, no further problems. Vision is restored to state prior to the eye injury. Medicare covered costs after copay.
Our experience here was very professional and great. The staffing here is excellent and helpful. Dr. Reiss was amazing to work with and the surgery performed by him went better than we could have ever imagined. Would highly recommend this place and him to everyone!
Dr. Minhee Cho is one of the kindest physicians I have ever seen. She is so thorough, explaining everything as she did the eye exam. I did end up having eye surgery….best experience. She was amazing, and so thorough after.
Dr Ko is a very professional person he treated my eye so far for many years
My eye has been better and better. Thank you,
Dr Fung is the best. He explains step by step procedure of what he will be doing to prevent further eye damage.
Retina institute staff were helpful, polite, and a joy to work with. I would recommend their services if my friends needed them.
Appreciate the doctors enthusiasm and knowledge. Spotted something on my retina Imaging that I wasn’t aware of and gave me some key pointers about nutrition. Thanks r i w!
The staff at RIW are thoughtful, kind, and professional. Dr. Benjamin Reiss is excellent. He explained everything to me and answered my endless questions. I’m sad to hear he is leaving RIW as he is the reason I went there. That’s why only 3 stars. Don’t know that I’d go there without him.
I have been going here for many months. I am always impressed with the help here. Always smiling and makes you comfortable.
Left feeling like a bother. I won’t explicitly name the doctor, because this isn’t a direct attack on them, but this is more so to make them aware of how their words can affect how the patient feels. I had laser done for a small retinal …
Everyone was great from the front office to the techs especially Jasmine and Rachel. Dr Ko took the time to explain everything very well. I left there knowing I was in good hands for the upcoming surgery.
I am very impressed with Dr Ko who, during my visits, gives me informative and detailed explanations regarding my issues and how I should work on them.
Had my follow up visit with Dr. Fung. Very polite and knowledgeable person. The staff is also very polite and caring. Great team to be with.
I was here for a retina exam. It was very thorough. I was impressed. The service and treatment by the employees was excellent. Dr. Fung was very nice and explained the results very thoroughly.
90% of the staff was very rude to my grandmother! They were very behind, but that does not justify their attitude especially towards the elderly. We were early to the appointment and generously patient.
Dr. Ko is a gifted surgeon, the staff is well-trained and knowledgeable, they appear to have the latest equipment, and, everyone is friendly, upbeat, and helpful. You would be in the best possible hands at Retina Eye.
I have been working through retinal vein occlusions for over ten years and have been with Dr. Ko for five of them – he doesn’t hold punches and we have always worked together to decide on the best course moving forward – eye injections aren’t something to look forward to but Dr. Ko definitely makes them less impactful.
As I am a patient suffering with glaucoma I have been subjected to the treatments required with regard to the conditions within my eyes. The treatment and care I have received from this institution has been extraordinary. Their …
Dr Ko thoroughly reviewed my situation and circumstances. I’m more than elated that I asked for a 2nd opinion because I feel like if I hadn’t, my results would’ve fallen short of my 100% perfect vision outcome! Thank You for being so precise Dr. Ko!
Dr Fung always treats me well (no pun intended). My injections are quickly yet professionally done and he answers any questions I may have
I was referred by my own doctor, and was thrilled that I was able to get an appointment so quickly, and they were able to do the procedure that I needed done, in-house. Quick, efficient, and Dr. Fung was awesome!
I have been going to Dr Ko for a long time, and never have I been disappointed. Dr. Ko is very Professional, he’s honest, he tells you what he sees in your eyes and tell you what the next step will be. I am a straight shooter myself, no …
Overall it has been a great experience. Costco Covington my little eye shop referred me to Retina Institute of Washington, Renton and I consider myself very fortunate that they did. …
I wish that I could remember the name of the last doctor that gave me injections for my retinopathy. He was so incredibly knowledgeable and very efficient. He told me the exact plan he had in regards to my health care and explained why he …
