20 Years of Wearing Glasses and Finally No More! - New York

I had my procedure recently at Dr. Chynn's office. Dr. Chynn is extremely sharp, very nice and is always ready to answer questions. The staff are professional and nice too. When I visited for the consultation, I was introduced to a "buddy patient" via email (after her consent of course) so that I can ask questions more from the patient's perspective. This was very helpful as I got the chance...

Dr. Chynn and the Staff at Park Avenue LASEK Laser Center Are Very Professional and Amazing - New York, NY

I had an excellent experience at Dr. Chynn's Laser Vision Center in NYC. Dr. Chynn is fixing extreme cases that no other surgeon in the U.S. let alone NYC can touch. Dr. Chynn can do this because of the no-flap LASEK technique he invented at Harvard. I flew in all the way from Bulgaria because no surgeon in Europe has his experience with these cases. Now I can see 20/20 or better than I was...

Park Avenue Lasek - So Amazing!! -New York, NY

Dr. Chynn and his staff know what they're talking about. Period. Every question I've asked has been met with nothing but professionalism and a genuine desire for me to have all the info I need. All the staff members are friendly and I personally love Dr. Chynn. People may not get his sense of humor and be offended, etc. but I actually love it and think he's super funny, which helped alleviate any anxiety I may have had about the procedure. He is very efficient and as a result, doesn't beat around the bush, which I definitely appreciate. p.s. What sealed the deal for me was the fact that Dr. Chynn PERFECTED this process. I mean, why go anywhere else when you can go directly to the person who perfected it? He does the surgery in a room that has glass walls, so that anyone walking outside can see it as well. Talk about super confident! That's what I would want from any doctor doing a serious procedure on me.

Well Worth the Results - Flat Iron District, NYC

An internet search. The staff at Park Avenue Lasek were all really friendly, relaxed and professional. I had absolutely no pressure at all into getting any specific procedure done and they made sure I was a proper candidate and that I understood the process very well before I decided to go through with it all. They were extremely helpful with every step of the process, answered any questions I had and although they were a bit strict with us taking the precautions necessary afterwards, it has been well worth the result. They were also extremely flexible when it came to medical insurance and helped to make sure I got the best coverage possible for my medications. Can't be more happy about that. It's been a pleasant experience and I would definitely recommend Dr Chynn and his staff.

Great Place for LASEK - New York

This is a great office for LASEk with great staffs. Especially Dr. Chynn, he is very smart with great humor, he went to 5 Ivy League schools including Harvard and Columbia. I was recommended to Dr. Chynn by my cousin, she had her LASEK done by Dr. Chynn and she is very satisfied with her surgery. I went in for a free consultation with Dr. Chynn on March, the staffs are very knowledgeable. They tell you everything you need to know about the surgery and keep repeating it making sure you understand it to get the best result from your surgery. Dr. Chynn’s office is the only office that offers non-invasive and non-cutting procedures. No flap is cut into your eye, so you don’t have to worry about a flap complication comparing to LASIK. Price is a big issue for me, but the Dr. Chynn great staff worked with me to get it down somewhere close enough that I am willing to pay. They have a lot of great offers, you might actually get $2000 off.

Worth a Flight - Changed my Life

DR. Chynn was kind patient and he did an amazing job. The entire staff was just great. I had to get on a plane for the procedure with him. It was worth it. It's my eyes after all. I didn't mind traveling for the best.

Personal Statement

Dr. Chynn was the 1st LASIK surgeon in NY to get LASIK himself but suffered from dry eyes & night glare, so switched to non-cutting LASEK in 2003. He has performed more LASEKs than any other MD in the world
