I have been seeing Dr. Katz for over 10 years. He did my cataract surgery, and I see great. He is also treating my glaucoma - has been stable for years. He is extremely nice and attentive, as are his staff. Could not recommend him more highly
Espoo, 18 |
Dr. Katz has been treating my glaucoma for over ten years. I was originally referred from my optometrist when I noticed I could not see to the side out of my right eye. Dr. Katz has successfully treated my glaucoma over the last decade and has prevented any further visual loss. I could not recommend him more highly. He's the best!

I had cataract surgery in my right eye done at the university - was poorly done, had complications and ended up with poor vision. I was very scared to get my left eye done, but it got to the point where I could not drive anymore, so I went to see Dr. Katz. He put me at ease, explained exactly what was going to be done, and the surgery went great. I can now see again (at least out of the eye that Dr. Katz did). I am so happy with him.
in Chelsea, MI |
This was my first visit to Dr. Katz. I was a little put off by the long long for checkin until I realized that all of the patients there were not just for Dr. Katz. After check in, I was called back quickly. The nurse was extremely nice, and Dr. Katz did a thorough exam, realized I had had lasik surgery even though I forgot to tell them (as it was done about 20 years ago). Very happy with my visit.
in Canton, MI |
Came in just for a routine yearly exam. Staff could not have been friendlier. Minimal wait to see the Dr. Eye exam was thorough. Got new prescription for glasses which work great. Dr. Katz found a small freckle in the back of the eye that he recommended yearly observation. Great office

I had been followed for over 20 years at U of M with glaucoma. My glaucoma was progressing, and I eventually underwent surgery at U of M, although it was not effective as my pressure remained in the high 20's despite surgery. A physician friend suggested that I see Dr. Katz, who I did. He performed surgery which was very successful, and my pressure has been around 12 ever since. Highly recommended!
Ft Lauderdale, FL |
He is a very friendly and talented physician. He did cataract surgery on both of my eyes - I was extremely nervous, but he walked me through the whole thing. I could not be more pleased with the surgery itself as well as the results. I can see so well now. I had no idea how bad my vision had really gotten. I highly recommend him.
in Ann Arbor, MI |
Staff in office were very friendly and efficient. Dr. Katz came highly recommended and was very competent. Diagnosed my problem first visit, prescribed medicine which cleared things up in a week. Very pleased with my visits.
in Ann Arbor, MI |
I have been seeing Dr. Katz for over 5 years. He has always taken excellent care of myself and my family. Couldn't recommend a doctor more highly than him. He is great. Nice, caring, and always listens to me.
