LASEK Eye Surgery at Park Avenue LASEK: The Safer, Flap-Free Vision Correction
Because Non-Cutting is the Safest™
Imagine life without glasses or contact lenses. At Park Avenue LASEK, we offer a cutting-edge alternative to LASIK—one that is safer, gentler, and ideal for those who have been told they’re not candidates for LASIK. If you’re ready to experience clear vision with a minimally invasive procedure, LASEK may be the perfect option for you.
What is LASEK?
LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is an advanced, non-cutting laser vision correction procedure. Unlike traditional LASIK, LASEK does not involve creating a corneal flap, making it a safer option for those with thinner corneas or a higher risk of complications.
With LASEK, the outer layer of the cornea (the epithelium) is gently lifted and the underlying cornea is reshaped using an excimer laser to correct refractive errors such as nearsightedness, farsightedness, and astigmatism.
Why Choose LASEK?
No Cutting, No Flap: Unlike LASIK, LASEK doesn’t cut into the cornea, reducing the risk of flap-related complications like dislocation or infection.
Ideal for Thin Corneas: Many people are told they can’t get LASIK due to thin or irregular corneas. LASEK offers a flap-free alternative that’s better suited for these conditions.
Lower Risk of Dry Eyes: LASEK is gentler on the corneal nerves, significantly reducing the chances of post-surgery dry eye compared to LASIK.
Safe for Active Lifestyles: If you play contact sports or have a job with a higher risk of eye trauma, do martial arts, boxing, exteme sports LASEK is the better choice, as there’s no flap that could be dislodged, unlike LASIK which may lead to a condition where your flap may tear off.
The Benefits of LASEK at Park Avenue LASEK
Expertise in LASEK Only: Dr. Chynn and his team at Park Avenue LASEK exclusively perform LASEK—not LASIK. This specialized focus means you are treated by true experts in the field of flap-free laser vision correction.
Personalized Care: We understand that every eye is different. That’s why we tailor every procedure specifically to your unique vision needs, ensuring the best possible outcome.
Proven Results: Thousands of patients have trusted Park Avenue LASEK to correct their vision, achieving clear, sharp eyesight without glasses or contacts.
Who is a Good Candidate for LASEK?
LASEK is ideal for:
Individuals with Thin or Irregular Corneas: If LASIK isn’t an option for you, LASEK may be the solution.
Chronic Dry Eye Sufferers: LASEK offers a lower risk of worsening dry eye symptoms.
Athletes and Active Individuals: Anyone involved in contact sports or activities that put their eyes at risk will benefit from the safety LASEK offers.
Those Seeking a Safer Alternative to LASIK: If you’re concerned about the risks associated with creating a corneal flap, LASEK provides peace of mind with its flap-free technique.
What to Expect During Recovery
After LASEK, you can expect a slightly longer recovery period compared to LASIK, but the results are worth it. It takes a few days longer but you avoid dry eyes and night glare that you usually get after LASIK. Your vision will continue to stabilize and improve over the next several weeks, providing you with the clear, crisp vision you’ve always dreamed of.
At Park Avenue LASEK, we guide you through every step of the recovery process, ensuring your comfort and successful results.

It's been two months since my epiLASEK surgery with Dr. Chynn and I'm really happy with the results: better than 20/20 vision and my close up screen vision is still perfect.I had a straightforward case of myopia (-1.5) and I can now go cycling in the rain, see how truly dirty my shower is, and I never have to shop for glasses again.I'm a software engineer so I was a little worried that improving my distance vision would come at the cost of my close up vision. But my vision when I'm staring at a screen all day has remained perfect. I was also worried about the possibility of dry eye, and only experienced it briefly for the first few weeks after the surgery.I got the comfort package so I was very relaxed during the procedure. The surgery itself is actually no big deal. I had to look at a flashing light for 10 seconds in one eye and 15 in the other. If you can follow instructions diligently, you'll get a great outcome.I'm the type of person who does extensive research before buying anything expensive. In my view, the vacuum-assisted epiLASEK surgery that Dr. Chynn offers is simply superior, and worth the extra cost. The trade off compared to regular LASIK seems to be recovery time; for me, the cost of keeping my eyes closed a few extra days during recovery is worth having the best vision I can get for many years to come.What's nice is the price transparency and I like that there are several options to help reduce the cost. You can go on the website and download the pricing form to see exactly how the cost of your surgery will be calculated. Pricing feels very fair, unlike most LASIK places.I admire that Dr. Chynn does things his own way and is focused on the very best outcomes for patients. I feel fortunate to have found Park Avenue LASEK. In particular, I appreciate the clear and detailed aftercare instructions, cautious follow-up exams, and systematic regimens to minimize side effects like MGD.Dr. D., Constantin, and Britney have been handling my follow up appointments and they have been great. It's been really satisfying to see my vision improve with every visit. 10/10

I had an extreme prescription before getting LASEK surgery and it improved not even a week after surgery. LASEK is a safer, no cutting. No dry eyes, no halos, no night glare. You should choose Dr Chynn and Park Avenue Lasek for your laser eye surgery

I decided to leave a review because I saw a few people saying "fake 5 stars reviews" and I am too grateful to let that slide. I had my surgery 11 years ago, June or July of 2015. I still have great vision and no complaints about surgery. This surgery was the best decision I've ever made.

Dr. Chynn is truly exceptional—brilliant, precise, and an absolute expert in his field. From start to finish, the entire process was seamless, professional, and thoughtfully handled.I chose him for his deep experience with Asian eyes, and his expertise is undeniable. He understands the nuance and delivers results that feel both natural and highly refined.The non-cutting approach made the procedure far less intimidating, and recovery has been incredibly manageable. I’m beyond happy with my decision—he is genuinely one of the best at what he does!

I went for a LASIK consultation at Diamond Vision but was diagnosed with Keratoconus. They didn’t bother referring me to a cornea surgeon; they just said it wasn’t safe to do LASIKI googled & found that Dr Chynn is the only surgeon adding LASEK to CXL, so I’d see better afterwards, instead of only “not worse”He accepted my insurance for the CXL & I had to pay a few thousand dollars for his special noncutting LASEK procedure. But I thought it was worth that to see betterNow 2 months after my surgery, I’m seeing even better than I was in glasses or contacts!Anyone who has KC & needs CXL, or anyone who can’t get LASIK should see Dr Chynn. So you can meet your desire to see BETTER, instead of just “not worse”

i had an extreme Rx of -12! so i was past LASIK parameters. my dad did a lot of research so figired out that i COULD get the non-cutting LASEK. i’m now 2 months out & legal to drive day or night. before my LASEK without my glasses, i could only see shapes, i wouldn’t even be able to see the big E. so anyone who was told that they can’t get LASIK should see if they might be able to get LASEK!;)

Dr. Chynn is excellent. I’ve been wearing reading glasses for awhile and now I’ll never need to wear them again. I’ll refer all my children, family and friends. Safest center in NYC!

I’m so happy that I discovered this place ! I got rid of my reading glasses which I didn’t know was possible. I’ll never need to wear reading glasses again. This was safe and not painful. I’d recommend it to any of my friends and family. Thank you DrChynn!

I’m in ortho-k lenses because that’s common in China so I came here for new ones. I lost a lens so they gave me a replacement soft lens for free. Eventually I’ll just get LASEK & forget about those lenses forever

Dr Chynn is clearly a very brilliant surgeon with a deep understanding of his field. I've struggled with redness in both eyes for many years, but one in particular has caused me more issues. Constantly gets inflamed at many different times every day, and when very red can be quite embarrassing. Dr Chynn seemed to be the only surgeon able to safely address red veins on the conjunctiva. I only had one area treated, I wasn't looking for perfection, only improvement, and it has definitely improved. Procedure is relatively quick - less than 30 minutes maybe - and didn't hurt due to the numbing drops. Would definitely recommend Dr Chynn if this problem really bothers you.

So, I'm going to make this a comprehensive review so everyone knows what they're walking into. Firstly, without a doubt if you are choosing park avenue lasek you are doing so because you have an opportunity to work with the world's best eye surgeon. Dr Chynns credentials speak for themselves, let alone the fact his innovations mean in the 21st century we have access to an eye surgery procedure (LASEK) that covers any concern anyone might have had about traditional lasik, or the arduous healing time of regular prk.I had my lasek procedure a month and a week ago. My left eye is doing great, and my right needs some further correction. Is this a problem? No. I get free corrections for a whole year. The post-op care is beyond belief, any time and day of the week, I have a question or concern I've been answered by Dr Chynn or the sweet and amazing Dr D. Dr Chynn, figured out on my post op follow up yesterday I needed cautery as my eyes were losing tears (puncta was too large) - leading to very dry eyes. He did my right eye totally free of charge, and for the first time in years I woke up with a normal feeling right eye.Is it scary if your eye isn't perfectly corrected first time round? Yes. But, the service here covers that, and I know I'm going with the best procedure possible on the market in 2025. There are some concerns in negative reviews about how Dr chynn treats his staff. I'll just say that no doubt Dr Chynn is a total taskmaster and is meticulous about how his office is run. And is definitely wry and exacting in character, But, if you want to trust someone with your eyes, wouldn't you want to have someone be totally on top of their shit?All the staff in the office are lovely, Dr D is the yin to Dr Chynns yang, and divine has been the sweetest person to correspond with at the front desk.Looking forward to my final correction next month and thanks to the whole team for their care!BestGeorge

I am a physician and was looking into getting LASEK as I was previously told my corneas are too thin for LASIK. I found Dr. Chynn from a google search. He sees you personally for the initial consult, which is not something every practice does. The procedure itself was not as scary as I imagined it to be, and was over quickly. The cost was also cheaper than I thought, and you can finance it with CareCredit.I’m about 1 month out, and I have 20/15 vision, which is better than I was seeing in glasses/contacts. Initially had some dry eyes but that has mostly gone away, which is a side effect that is notably more prominent in LASIK. Would highly recommend this practice and this procedure!
