Why Choose Dr. Chynn?Emil William Chynn, MD is New York City’s most experienced No-Cut, No-Flap, All-Laser surgeon (this means he has performed more LASEK and epiLASEK procedures than any other refractive surgeon in NYC, almost 17,000 to date; this is because every other full-time refractive surgeon in NYC with a laser center performs mostly the older cutting LASIK or IntraLase procedures, whereas Dr. Chynn made the decision several years ago to perform exclusively the newer non-cutting LASEK procedure)!
How can we prove this? Simple—because Dr. Chynn:
1. Was the 1st full-time refractive surgeon in NYC to stop performing the older, cutting LASIK procedure (in 2003)
2. Was the 1st surgeon in NYC to perform exclusively the more modern, safer, less invasive, No-Cut, No-Flap, All-Laser LASEK and epi-LASEK procedures (in 2003). Other surgeons sometimes perform LASEK over LASIK in cases where it is not safe to cut a LASIK flap, as in thin corneas, high prescriptions, irregular astigmatism, dry eyes, nervous patients who might squeeze during the flap cutting process; Dr. Chynn just decided to do the noncutting LASEK procedure in EVERY patient.
3. He performs over 1,000 non-cutting procedures each and every year—more non-cutting procedures than any other laser vision correction surgeon in NYC)
4. Dr. Chynn has performed over 17,000 procedures, including LASIK, LASEK, PTK, PRK, AK, and PK. Today, Dr. Chynn is personally performing approximately 1,000 procedures per year! (e.g. moadel, niksarli, speaker, etc.)
5. Of all the ophthalmologists in New York, Dr. Chynn is the only Harvard-trained surgeon who has had LASIK himself and is now 20/20!

Dr. Chynn was an undergraduate at Dartmouth College and attended medical school at Columbia University’s College of Physicians & Surgeons (typically ranked the #1 medical school in New York State). He completed his residency at the world-famous Harvard University’s Massachusetts Eye & Ear Infirmary, where he was on the teaching faculty of Harvard Medical School.
After Harvard, Dr. Chynn could have gone out and performed refractive surgery (like many doctors in NYC who never completed a fellowship). Instead, he chose to spend an additional year completing a full fellowship in Corneal Transplantation & Refractive Surgery at Emory University in Atlanta, under George Waring, MD, who introduced RK and LASIK to the US.
Dr. Chynn has also published his first non-medical book, called Chinese Proverbs For Today’s World. You can order it now or buy it at Amazon or at your local bookstore!
Dr. Chynn has published extensively, both nationally and internationally. He is first author on over a dozen peer-reviewed publications, including all three leading ophthalmic journals in the United States–Ophthalmology, Archives of Ophthalmology, and American Journal of Ophthalmology–a rare distinction. He has published internationally in such prestigious journals as the British Journal of Ophthalmology and International Ophthalmology Clinics. Dr. Chynn has published over 100 articles on LASIK, laser vision correction, refractive surgery, and corneal transplantation.
Dr. Emil William Chynn has published over a dozen peer-reviewed articles in the ophthalmic literature, including articles in each of the top three ophthalmic journals — Ophthalmology, Archives of Ophthalmology, and American Journal of Ophthalmology — a rare distinction.
In addition, Dr. Chynn has published over 100 articles in non-peer reviewed literature, including many in Ophthalmology Times, the #1 popular journal in ophthalmology (according to annual readership and sales figures, provided by OT).
These articles report on the latest advances in LASIK and the more advanced LASEK and epi-LASEK laser vision correction techniques and are widely read by eye surgeons across the US — especially those who are unable to attend the prominent meetings covered (the American Academy of Ophthalmology, the American Society of Cataract and Refractive Surgeons, the Association for Research in Vision and Ophthalmology).
Unfortunately for our visitors, Dr. Chynn wrote these articles not for the lay public, but for MD’s, PhD’s, Odds, and other doctors engaged in either clinical practice or research.
Nevertheless, it is both interesting and instructive to take a few minutes and read about the incredible advances going on in this field! Obviously, by attending meetings, conducting research, and writing, Dr. Chynn remains at the cutting-edge of this rapidly-advancing technology — assuring you of the latest in Laser Vision Correction expertise.
