Effective & Safe Treatment for Keratoconus
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.
What is the goal of cross-linking?
CXL is FDA-approved, and it has demonstrated a high degree of effectiveness in treating keratoconus. This treatment aims to strengthen the cornea in order to stop the progression of corneal warpage. However, some people see even more dramatic improvements in their vision, due to the way their cornea flattens after CXL (even though this is not the real purpose of cross-linking!).
How is the cross-linking procedure done?
The simple procedure is done in-office and it is entirely painless.
- Dr. Chynn will drop a special solution of riboflavin (B-vitamin) on your cornea for 30 minutes.
- Next, your eyes will be exposed to 10-30 minutes of UV light. The intensity of these light waves are similar to the sterilizing blue lights you’ve seen at the deli counter.
- Wait for results! Typically, our New York City eye care patients notice results within one week, and most of the effects are experienced within one month.
Are there risks or complications involved with CXL?
CXL as a treatment for keratoconus is a promising procedure that leads to very positive results – with minimal risks involved. It was approved for use in Europe over 10 years ago, and it has been performed safely and successfully on tens of thousands of patients worldwide.
Regarding complications, the most common complaint is that CXL doesn’t stabilize the cornea and the patient’s condition continues to deteriorate. Simply put, CXL doesn’t work. However, this is the same outcome as if the procedure was never done – so it isn’t much of a “complication.”
Very rarely, people experience scarring or haze as a complication, or they have endothelial decompensation that requires a corneal transplant to correct it. Of course, had many of these same patients not undergone CXL, they may have eventually needed a corneal transplant to treat their keratoconus.
Am I a candidate for cross-linking in New York City?
