Cross-linking (CXL)
Effective & Safe Treatment for
Keratoconus (KC) in NYC
We are proud to offer collagen cross-linking (CXL) as a treatment for keratoconus and other corneal disorders that lead to irregular astigmatism. During his education at Harvard, Dr. Emil Chynn trained with the physician who has presented and published most extensively on CXL in the world.
Now, after attending additional conferences and seminars on CXL, Dr. Chynn specializes in this revolutionary procedure and performs it at his New York City office. Park Avenue LASEK has the distinction of being one of the very first eye care clinics in New York City to provide CXL.

Dr. Chynn & Park Avenue
LASEK & CXL
Dr. Chynn and Park Avenue LASEK have been performing CXL/KXL under IRB (Institutional Review Board) supervision for several years. We have more years of experience than almost every other center, private or hospital-based/university, and more patients treated, as well.
CORNEAL CROSSLINKING (CXL) in New York, NY
Corneal crosslinking (CXL) was developed in 1998 by Theo Seiler, MD (whom Dr. Chynn knows) and has been shown in numerous clinical trials to strengthen the cornea to treat conditions such as:
- Keratoconus (KC)
- Pellucid Marginal Degeneration (PMD)
- Ectasia after LASIK
Riboflavin, a form of vitamin-B2, is applied to the cornea in the form of drops, followed by treatment with ultraviolet A (UV-A) light, which adds crosslinks to the cornea collagen, much like rebar is added to concrete to make it stronger. This safe treatment, which has been recently approved by the FDA, so medical insurance is starting to cover it, can slow or even stop the progression of keratoconus, PMD, or ectasia after the cutting LASIK procedure (ectasia after PRK/ LASEK is much less common because those procedures are non-cutting).
