The staff was cordial and efficient. I've been to many ophthalmology offices in my lifetime. They took all the tests and even some of the extras that I was accustomed to having. All needed as a first visit and to have a record of. I certainly will return.

I had a terrible PRK experience with my original surgeon. While the surgery was done successfully, my eyes took a year to heal and my surgeon didn't take the time to listen, address, or explain my concerns. I searched endlessly for2nd opinions. I finally found Dr. Koster. He was the first surgeon to really take the time to conduct all the tests necessary to understand my predicament and he had fantastic bedside manner the whole way through. His explanation was clear and he was very patient and understanding of all my questions. In the end, I have terribly dry eyes and that is what is affecting the clarity of my vision today. I'm not sure if I would have done PRK if my original surgeon had told me this, but I'm glad that I found Dr. Koster now for all my check ups here on out. I finally have some peace of mind thanks to Dr. Koster.

The doctor was lovely, but the practice felt like a factory. Service was impersonal and extremely slow. And it’s in a basement so there is no cell phone reception and their WiFi was down which is problematic on a workday when you have to spend over an hour down there.

The visit took about a half hour in total, which was great with my busy schedule. Dr. Koster came in for a quick review of both eyes and then let the optometrist on staff review my glasses and prescriptions. Everyone Iencountered was friendly and helpful. WIll be returning here for all my vision needs.

Deceptive Billing – Go to this doctor at your own peril! This is to warn prospective visitor’s of Doctor Harry Koster's office about deceptive billing practices whereby the office conducts unasked for checks and then bills for those checks.I went to the doctor’s office and asked them to do a routine eye exam that would be 100% covered by my insurance policy. After doing the preliminary check, they asked me to come back another day for the final part of the exam for which they would need to dilate my eyes. I later received a bill from the Doctor’s office claiming i had complained of a dry eye and asked for a check up! A total lie! I did not ask them to do any further tests than were covered. The billing department is very rude and intimidating – ‘You have to pay, you asked for the tests’ is all they will say. NOTE - the doctor herself was not bad, but the billing dept killed my experienced.

The doctor was sarcastic and made fun of me explaining the pain in my eyes. He was rude and obnoxious. Not professional. Nasty behavior for a doctor.

I am very upset that this Doctor was "in-network" for my health insurance plan but the optometrist, who was responsible for administering a new contact prescription (THE ENTIRE REASON FOR MY VISIT), was out of network. This entirely makes nosense, and I feel deceived to have been lured in to a general eye consultation with an in-network doctor only to find out after the appointment that the "contact fitting" was out of network. Now I have to go to a different doctor who hopefully has a corresponding in-network optometrist. VERY FRUSTRATING. This review is not so much against Dr. Koster but instead against his entire practice and it blatantly misleads its potential patients.

Confirm with them the payment and treatment details before visiting the office. They say something else on the phone and charge you anyways when at the office. Got a general eye exam which was free per 12months in my insurance andstill was charged copay because they are something extra special. Anyways never going back.

This is a LASIK factory. You're just another zombie going through the eye surgery conveyor belt. No explanation of the procedure (pre-, intra-, post-), insufficient information given when I asked for a comparison between PRK and LASIK givenmy particular circumstances / concerns, nor a reasonable discussion of risks. Total time with doctor was about 180 seconds. I was then pushed to the finance lady which knew nothing and could not answer my detailed questions about the type of laser used, measurement system employed, etc. Pro: was the cheapest out of my 5 consultations (actually a CON) Con: they use an outdated laser & measurement system. Do your research on the best laser (VISX STAR S4) & latest measurement technology (iDesign). Very few surgeons in NYC offer this pairing. Overall: Got my eye surgery done elsewhere and was extremely satisfied.

My vision is something very important to me and what I like about this practice is that I actually saw a highly trained and qualified doctor even though I have Medicaid ( student life) . I got to see an MDand an optometrist ! The greeting staff and tech staff are ok but the doctors are the best. A lot of tests are done that are not otherwise done at an optical. Office is very clean and all clean new equipment Highly recommended especially for annual exam check ups.
