Meet The Team

Park Avenue LASEK combines the traditional values of a small private practice with the most innovative medical advances in ophthalmology.

At Park Avenue LASEK our staff is here to make your experience as smooth and pleasant as possible throughout every stage of your process. Ask us anything about your procedure, we are here as a resource for you!

Dr. Chynn and Park Avenue LASEK have a unique philosophy, which is based on openness, honesty, and mutual benefit.

Dr. Chynn and Park Avenue LASEK are a 100% non-cutting, non-invasive laser vision correction centre in New York City.

We invite people in to watch live surgery, and invite patients to freely share their experience with other patients.  We don’t even monitor this interaction (after we get the patient’s permission), because we want both parties to be able to interact freely. This allows the customer to get it “straight from the horse’s mouth.”

Other laser centers typically segregate their preop and postop patients, because they don’t want any possibility for a postop who is not perfectly happy speaking to potential customer.

Dr. Chynn actually encourages this interaction, as he wants people to have “realistic expectations” (in terms of recovery time, etc.) so we can meet or exceed them. In terms of mutual benefit, we operate on the “pay it forward” philosophy.  Our patients are almost always to help support or “coach” a potential patient, as they have often had that assistance themselves!

  • Emil Chynn, MD, FACS, MBA
    Medical Director, Lead Surgeon

    The most experienced & famous LASEK surgeon in the world.

    Dr. Chynn is the most experienced & famous LASEK surgeon in the world.  He gives invited talks and lectures nationally and internationally every year, where he teaches surgeons how LASEK can safely treat patients who can’t get LASIK. This is why he switched from performing 5,000 LASIKs non-invasive LASEK (20,000+ procedures). 

    Dr. Chynn graduated from Dartmouth College and got his MD from Columbia University, the #1 medical school in NY. He completed his residency in ophthalmology in 1996 at Harvard and his fellowship in Corneal Transplantation & Refractive Surgery at Emory University.  Dr. Chynn was on the teaching faculty of Manhattan Eye, Ear & Throat Hospital and New York Eye & Ear Infirmary, which Top Specialty Eye Hospitals ranked by US News & World Report. He heads his own Fellowship in Refractive Surgery—the largest of 10 in the US! Dr. Chynn was the 1st eye surgeon in the NY area to get LASIK himself (in 1999, for high myopia and astigmatism), and although he is still seeing well, he has night glare and dry eyes.  This is why he switched from the cutting LASIK to the much safer, non-invasive, non-cutting LASEK in 2005, to eliminate those problems.

    He’s also the only laser surgeon in NY who provides his patients with his personal email and cell phone, so you can contact him 24/7!

  • Tetyana Dovzhuk, MD, PhD
    Cornea & Refractive Fellow & Retina Specialist

    Experienced ophthalmic surgeon.

    “Dr. D” received her MD at Sumy Medical University and her PhD in retina at Kharkiv National Medical University in Ukraine, where she also completed her residency in ophthalmology.

    For 6 years, Dr. D ran the largest laser vision center in Ukraine (“AILAS”), where she performed and assisted on thousands of LASIK cases.  She decided to come to PAL to spend a year with Dr. Chynn to master the newer, safer LASEK procedure.

  • Rhett
    Office Mascot

    Borzoi, our office mascot.

    Rhett is the Official Mascot of our practice, and hangs out in the back office nearly every day (Dr. Chynn walks to work with him).  Rhett is a borzoi, or Russian wolfhound.  Before the Russian Revolution, only members of the Russian royal family could own borzois!  Rhett has been featured in photoshoots for “Women’s Health” and for Valentino, and has raised thousands of $ as a therapy dog, including donations to the ASPCA & Guiding Eyes, which trains seeing eye dogs.  If you’re waiting too long/bored, just ask for Rhett, and you can walk him around the block!
