Why Lasik Xtra?

The decision whether or not to undergo LASIK eye surgery requires careful consideration.

It is an investment in something invaluable—your quality of life, and it can be a significant financial commitment as well. That’s why we’ve developed Lasik Xtra, a procedure performed during your LASIK surgery that strengthens the cornea of the eye and has the potential to:1,2


Extend the longevity of LASIK, decreasing the need for touch-up procedures


Improve the accuracy of a LASIK procedure


Provide peace of mind in knowing you are getting the highest quality, safest eye care possible


Reduce the potential for long-term changes in your vision

Benefits of Xtra

If you are a candidate for LASIK, SMILE, or PRK you are likely a candidate for Lasik Xtra, SMILE Xtra, or PRK Xtra too. Talk to your surgeon to see if the benefits are right for you.

Over 200,000 eyes have been successfully treated with Lasik Xtra around the world using the KXL System.

Clinical Data

Lasik Xtra was shown to be a promising technique to reduce refractive regression following refractive surgery, particularly in categories of patients with high myopia or hyperopia6.

Additionally, some studies suggested the potential to improve the predictability of the refractive outcome in Lasik Xtra as compared to LASIK alone7.

“Studies have shown that cross-linking at the time of refractive surgery could also improve the stability of the refractive outcome over time and reduce regression.”
