A world renown surgeon.

Dr. Emil W. Chynn, MD, FACS, MBA


About Dr. Chynn Chynn 3Dr. Chynn is, to the best of our knowledge, the only high-volume refractive surgeon in the US who performs 100% non-cutting Advanced Surface Ablations (ASA, defined here as LASEK or epi-LASEK), and who used to perform LASIK and had it himself, but switched to eliminate ALL flap-related complications (since there is no flap cut in ASA). All refractive surgeons will admit that the majority (defined as > 50%) of all LASIK complications are in some way flap-related (e.g., incomplete flap, full flap, buttonhole flap, flap striae, wrinkles, debris under the flap, DLK, post-LASIK ectasia or KC, etc.), so by eliminating the flap step, you eliminate the majority of possible complications!:)


He was an Attending Surgeon and on the Clinical Faculty at New York Eye & Ear Infirmary, which has been recognized annually as the Top Specialty Eye Hospital in New York City by US News & World Report. He was the founding Co-Director of Refractive Surgery at St. Vincent’s Hospital, where he completed his internship in 1992. He was Resident Instructor in Cornea and Refractive Surgery at Manhattan Eye, Ear, & Throat Hospital.

As part of his academic responsibilities, Dr. Chynn has taught over 50 eye surgeons how to perform LASIK and the more modern, no-cut LASEK procedures.

Why choose Dr. Chynn?
New York City’s most experienced No-Cut, No-Flap, All-Laser surgeon (this means he has performed more LASEK and epiLASEK (epi-LASIK) procedures than any other refractive surgeon in NYC, almost 30.000 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)!

Dartmouth, Columbia, Harvard, Emory, NYU are just the short list of institutions Dr. Chynn studied at
