Corneal Crosslinking
Considering Crosslinking for Keratoconus?
Learn About Your Options at Park Avenue LASEK
Are you considering Corneal Crosslinking (CXL) to treat keratoconus? At Park Avenue LASEK, we understand how challenging it can be to deal with the progressive thinning and bulging of the cornea caused by keratoconus. We offer CXL, a highly effective procedure designed to halt the progression of keratoconus, helping you maintain your vision and prevent further deterioration.
What is Corneal Crosslinking (CXL)?
Corneal Crosslinking (CXL) is an innovative procedure used to treat keratoconus, a condition where the cornea becomes progressively thinner and cone-shaped. This minimally invasive treatment involves applying riboflavin (vitamin B2) eye drops and using ultraviolet (UV) light to strengthen the collagen fibers in the cornea. The goal of crosslinking is to stabilize the cornea, halting the progression of keratoconus and preventing it from worsening.
Why Choose Corneal Crosslinking (CXL)?
Halts the Progression of Keratoconus: CXL is currently the only FDA-approved treatment that can effectively stop keratoconus from getting worse. By strengthening the cornea, CXL prevents the condition from advancing, which is crucial in preserving your vision.
Non-Surgical Treatment: Crosslinking is a minimally invasive procedure that doesn’t require major surgery or corneal replacement, making it a safer option for stabilizing your vision.
Preserves Your Vision: By preventing keratoconus from progressing, CXL helps you maintain your existing vision and avoid the need for more invasive procedures, such as corneal transplants.
Is Corneal Crosslinking (CXL) Right for You?
Corneal Crosslinking (CXL) is ideal for patients in the early to moderate stages of keratoconus. If you have been diagnosed with keratoconus and are noticing changes in your vision, it’s important to seek treatment as soon as possible. Crosslinking works best when done early, before significant damage occurs. At Park Avenue LASEK, we offer a comprehensive assessment to determine if CXL is the best approach for stabilizing your condition.
Exploring Your Vision Correction Options
While CXL is an excellent treatment for halting the progression of keratoconus, it does not correct refractive errors. If you are looking to improve your vision in addition to treating keratoconus, LASEK may be an appropriate option. LASEK is a non-invasive laser vision correction procedure that reshapes the cornea, offering an opportunity to enhance visual acuity alongside the stabilization provided by crosslinking.

Dr. Chynn is a true genius at what he does. He did my first Lasek procedure in 2018. Because I have a thin cornea, regular lasik wasn't an option for me. Dr Chynn corrected my vision from -9.00 to 20/20! I didn't have any complications and healed perfectly. It was truly a medical miracle! Because I was quite young when I got it done my nearsightedness came back so I came right back to Dr. Chynn for my second procedure last week. As with the first, it went smoothly and his staff are all so incredibly nice and attentive. They make themselves available 24/7 via WhatsApp so that I can text them any questions I have. They're all very knowledgeable and well trained by Dr, Chynn.One word of caution: Dr Chynn is not for the faint of heart. He is very stern and strict about everyone following protocol so don't expect to be coddled. He's not a participation trophy / orange slices kinda guy. He's very direct which can seem a little alarming at first but just understand that he expects his staff to operate only at the highest standards. Come here if you want to be treated by a world class surgeon and get great results!

I recently had LASEK surgery, and I can confidently say it was one of the best decisions I’ve ever made. Not only am I thrilled with my results, but the level of care and support I received from Dr. Chynn and his team, especially Tarek, was truly exceptional.Dr. Chynn set the tone for an outstanding experience. During my initial consultation, he took the time to explain the entire procedure in detail, including why LASEK was the best option for my specific vision needs. His ability to clearly outline the steps, potential outcomes, and aftercare instructions made me feel completely at ease and confident in moving forward. A special shoutout to Tarek, who went above and beyond to assist me with the financial aspects of the procedure. He patiently worked with me to explore all payment options and ensure I was comfortable with my plan. His professionalism, empathy, and dedication made the process stress-free and manageable. The surgery itself was smooth and painless. Dr. Chynn was incredibly thorough, walking me through each step of the procedure as it was happening. This level of transparency was so reassuring and showed his commitment to ensuring I felt safe and informed. Recovery was as expected—mild discomfort during the first couple of days, but Dr. Chynn’s aftercare plan was meticulous. His clear instructions and the team’s follow-up care made all the difference. By the end of the first week, I noticed a dramatic improvement in my vision, and full recovery followed shortly after. My vision is now better than ever (20/15), and it feels amazing to wake up and see clearly without glasses or contacts. This surgery has completely transformed my life, and I couldn’t be happier with the results. Dr. Chynn’s expertise and thoroughness, combined with his entire staffs incredible support, made this an exceptional experience. If you’re considering LASEK, I wholeheartedly recommend this clinic. You’ll not only get outstanding medical care but also a team that truly prioritizes your well-being every step of the way.

Dr Chynn, or “Professor Chynn” as the staff refers to him is so good at what he does that he has trained hundreds of other doctors who have worked under him during his career, and it shows. I met with Dr D and she was amazing. She said when she first met Dr Chynn years ago she was skeptical that he could correct extreme prescriptions like -13 or complex conditions like amblyopia, ocular albinism, keratoconus, and nystagmus, but he showed her how he does it. She’s an MD/PhD surgeon and a retina specialist so the fact that she learned anything new after all of those accolades really speaks to how knowledgeable “the professor” truly is!Dr Chynn and Dr D remind me of a paternal and a maternal figure. Dr Chynn is tough because he wants the best outcomes for his patients and he is NOT SHY about correcting the staff, the doctors, or the patients. He only cares about excellent results and I love that about him. Dr D is kind because she connects with the patients on an emotional level and which really complements Dr Chynn in a perfect blendAnd with their powers combined, I’m now 20/15. Forget glasses, that’s for people who only want 20/20 vision 😜. I couldn’t be happier. Thanks to the whole team at Park Avenue LASEK!

One of my favorite things about Park Avenue LASEK is they put you in touch with someone who already had their LASEK with a prescription just like my own, AND they had the same job so I felt confident knowing they had my way of life in mind when correcting my visionI didnt think I would be able to afford the surgery and felt stuck in my glasses. Luckily, I was able to finance the whole thing and it only cost about $3/day! I felt great knowing I would save tens of thousands of dollars on glasses, lifetime!Dr Chynn is TOUGH and that’s the best thing I could ask for. He’s a perfectionist and that’s exactly how he gets perfect results. He treated me like his own son and was a great “father figure” when it came to telling me how to perform during the surgery and how to take my meds during post care. I couldn’t be happier with the results. I’m better than 20/20 and can’t remember the last time I saw this well. Maybe neverIf you’re thinking about getting this done, get it done asap. This man is a blessing and not enough people know about him and his safer LASEK over LASIK

I was looking into lasik and happened across LASEK, a safer, non-cutting procedure. No dry eyes, no halos, no night glare, no flap. I CHOSE Dr.chynn and Park avenue LASEK because he has done the procedure on his own eyes and he looked into why I have dry eyes. After Lasek, I’m glad that I can see everything without glasses or contactsI have dry eyes, -5.25 and -7.25

Dr Chynn and the Park Avenue LASEK staff have to be easily the best trained out there in this line of work. I know, because before I had my LASEK, I was desperate to find a solution to getting rid of contacts and glasses that didn't involve cutting from LASIK or pain and scarring from PRK. Out of every place I visited only Dr Chynn seemed the most knowledgeable and rightfully so, given his 5 Ivy League degrees and membership in MENSA. His staff knows more and is better versed in not only his LASEK surgery but even the types of surgeries other doctors performMy LASEK was June 1st, 2012. Six years later and my vision is still better than 20/20. I'm actually 20/15 without any side effects and I could not be more grateful. You'd think you'd get used to having better than perfect vision but honestly, you don't. Every now and then I have a moment where I'm impressed with how sharp something looksI sincerely wouldn't look elsewhere for a better surgeon. Dr Chynn can be brusque and at times curt. This stems from his perfectionist approach to everything in his life with exacting precision leading to optimal results for his patients. His no nonsense attitude ensures you get what you pay for. As a fellow New Yorker, I recognize and respect this approach in a world of wishy-washy types who just want to tell you what you want to hear. The truth is always going to be the truth and the safest option is always going to be LASEK

I had an incredible experience with Park Avenue LASEK. I purchased the platinum package and was able to fully resume my life after 3 days and my eye sight is perfect. Could not have asked for better results then with Dr Chynn.

Great Experience at Park Avenue LasekI had a fantastic experience at Park Avenue Lasek. Dr. Chynn and the team are highly professional and attentive. What really stood out to me was their willingness to answer questions via WhatsApp—something you don’t often find. It made a big difference in feeling supported throughout the process. I highly recommend them for their expertise and personal touch. Granted I am still in recovery so I will make any updates to this review regarding my vision as time progresses.

The procedure was quick and easy as my prescription was pretty low to begin with. Pricing was honest, I liked how there was transparency because there was a pricing sheet whereas a lot of other places, the prices weren’t solid and could be variable by patient. Front staff is very nice and personable. Make sure to follow the instructions and be on top of your medications for healing. There’s also a group chat with the entire staff, including the doctor himself, which is very nice because it allowed me to trust the process more.

I made the decision to do the LASEK procedure after wearing glasses for 21 years. It was a big decision but one I knew I needed and wanted to get it done at a place that had great reviews.I was told by a relative who had lasik done years ago that it was worth it. So I came to Dr. Chynn and learned about what he does now, Lasek and what this type of procedure involves.I was educated on the procedure, pre-op steps and post-op steps.As I did the procedure, I was grateful I had the comfort package as it helped my anxieties. The entire experience was very cool and painless. Recovery was over a few days and time went by fast as your eyes and body will just want to keep sleeping.No regrets about this surgery because now I’ll be able to learn how to swim without the fear of not seeing clearly!

Best decision I’ve ever made! Ever since my surgery, my vision has never been better. My original prescription was -4.25. Today it’s nearly 20/20 and it’s only going to get better. I cannot wait!! Dr. Chynn is excellent, along with his excellent staff! Thank you so much!

From 20/800(-6.75) to 20/15 vision in one week after my surgery! As a medical student I was very hesitant to get lasik done knowing the complications such as severe dry eye and night glares. Once I heard about the different surgery lasek and how this prevents those complications my interest was peaked. Dr Chynn is an incredible surgeon and I wouldn’t trust my eyes with anyone else.

I was a bad candidate for LASIK because I had a very extreme prescription. I met with Dr Chynn and his team and because they do a zero-cutting LASEK procedure it is not only safer but allows anyone who has high prescriptions/very bad vision to successfully correct their vision. I am loving not being stuck with glasses and contacts. Check them out

Praise God, I had my Park Avenue LASEK graduation! 💯🥹😃😇🙏🏿 My vision is excellent! Doctor Chynn and all of his constituents did a miraculous job! I highly recommend Park Avenue LASEK for anyone, especially with a high prescription in need of eye care. They work with smart and compliant patients. Be sure to follow the protocol given by the Surgeon and observe all ethical practices before, during, and after surgery. I thank the Surgeon and everyone here. Most importantly, I thank God for making it all possible! 🙏🏿

Doctor D was excellent! She went above and beyond to make sure my eye sight was perfect before I left. She is very knowledgeable and took the time to explain everything to me.

I traveled to NYC from out of state for Dr Chynn’s non-cutting, no-flap procedure so I could eliminate the risk of post-operative dryness, night glare, flap re-opening, etc. Two months later, I can now say that getting epi-LASEK surgery performed by Dr Chynn was well worth the added cost of travel. I am seeing 20/20 without any complications, and in his follow up care Dr Chynn is more responsive remotely than most physicians are in person! I highly recommend Dr Chynn.

Really happy with Nana and my experience here. Had high astigmatism and was really concerned about the dry eyes associated with LASIK. Also didn’t want the risk associated with the flap.LASEK was newer and a non-cutting version of LASIK without the flap, so was really happy to get the chance to get it done with Dr Chynn, who is one of the best in the field.Really excited to be able to be free of glasses and already able to see clearly quickly post-op!

I had a left eye that was lazy & had a -10.00 Rx with astigmatism. Many doctors said nothing could be done. Went to Dr Chynn & he said he’s the only doctor in the USA who’s routinely fixing eyes like mine. He let me speak to a former similar patient. Took my medical insurance. Got that eye seeing 20/25 which is almost perfect, and better than I ever saw with glasses or contacts—without them! You really owe it to yourself to check them out. Especially if you were told your case was “hopeless” like mine!

I had my LASEK surgery a week ago and have had a smooth recovery process. I chose to do this because it’s safer than LASIK and the effectiveness lasts longer. I’m satisfied with my results and can’t wait to start getting back into running/sports with my new eyes.
