Lasik Xtra is a procedure performed during your LASIK surgery that strengthens the cornea of the eye and has the potential to extend the longevity of LASIK, improve the accuracy of a LASIK procedure and reduce the potential for long-term changes in your vision.
Lasik Xtra is a three minute corneal cross-linking procedure performed in conjunction with Lasik.
Riboflavin (vitamin B2) is important for body growth, red blood cell production and assists in releasing energy from carbohydrates. Its food sources include dairy products, eggs, green leafy vegetables, lean meats, legumes and nuts. Breads and cereals are often fortified with riboflavin.
Ultra-Violet A (UVA)
UVA is one of the three types of invisible light rays given off by the sun (together with ultra-violet B and ultra-violet C) and is the weakest of the three.
The LASIK procedure
We apply numbing drops to the eye, and using a specially designed microkeratome we create a flap of tissue on the front of the cornea. The flap is lifted to allow the access to the cornea so it can be reshaped by removing layers of tissue to meet the refractive requirements of the patient to correct near-sightedness or far-sightedness.
The Lasik Xtra™ procedure
After the laser procedure, the riboflavin eye drops are applied to the corneal bed and allowed to soak for 1-2 minutes. The excess riboflavin is rinsed off and the doctor closes the corneal flap. The eye is then exposed to UVA light for a minute or so.
It's complete and you can go home!
The decision to undergo LASIK eye surgery requires careful consideration. It is an investment in something invaluable—your quality of life. That's why we offer Lasik Xtra, the next generation of vision correction that helps to protect the investment you have made in your vision.

Is it Right for Me?
If you are a candidate for LASIK, you are likely a candidate for Lasik Xtra too. Talk to your surgeon to see if the benefits of Lasik Xtra are right for you.
Incorporating Lasik Xtra into your LASIK procedure improves the strength of the cornea.
Lock-in the Prescription
Lasik Xtra may extend the longevity of your LASIK procedure and could eliminate the need for touch-up procedures, reducing the potential for long-term changes to your vision.
Improve Procedure Accuracy
Enjoy life with the better vision that Lasik Xtra can provide.

What is cross-linking?
Cross-linking is a medical procedure that combines the use of ultra-violet light and riboflavin eye drops to add biomechanical strength to the cornea.
What is Lasik Xtra™?
Lasik Xtra™ is a three minute corneal cross-linking procedure performed in conjunction with Lasik.
Are there any safety concerns regarding the use of ultra-violet light or riboflavin in the
The ultraviolet A light exposure during a Lasik Xtra™ procedure is comparable to, or even less than, the exposure of the eye to the ultraviolet light in sunlight for one full day outdoors in the summer. Riboflavin, also known as Vitamin B2, is naturally occurring in the body, including the eye. It is a photosensitizer that has been safely used in corneal cross-linking procedures for over a decade. Riboflavin is non-toxic and it is used as an additive in food and pharmaceuticals.
How does Lasik Xtra™ work?
After completion of a standard Lasik procedure, a few drops of riboflavin are applied to the cornea and then the riboflavin is exposed to ultraviolet A light. The light activates the riboflavin, which leads to the formation of chemical bonds between collagen molecules. These bonds strengthen the cornea.
Are there any age limits for Lasik Xtra™?
Patients that are good candidates for Lasik are generally eligible for Lasik Xtra™. Consult your eye care professional to learn whether Lasik Xtra™ is right for you.
Does Lasik Xtra™ require the epithelium to be removed?
No. During a standard Lasik procedure, a flap is made in the cornea. This flap allows the cross-linking portion of Lasik Xtra™ to be performed without epithelial removal.
Will the addition of Lasik Xtra™ to my Lasik procedure affect my Lasik recovery or visual
outcome in any way?
You should expect no change in your Lasik recovery or visual outcome from Lasik as a result of Lasik Xtra™.
Can Lasik Xtra™ be combined with other refractive treatments?
Yes, Lasik Xtra™ can be combined with PRK, LASEK and AK. Consult with your ophthalmologist to determine if cross-linking is best for you in conjunction with these other procedures.
Is Lasik Xtra™ the same as the corneal cross-linking used for conditions like keratoconus?
Generally yes. Corneal cross-linking, with slightly different procedure treatment parameters (longer time, higher power, etc.) than Lasik Xtra™, may be combined with corneal rings, phakic lens implants, refractive lens exchange, and to directly treat keratoconus.
I've already had Lasik, can I have the Lasik Xtra™ procedure?
Yes, in most instances Lasik Xtra™ can be performed at any time after having a Lasik procedure, even years later. Your ophthalmologist also may recommend Lasik Xtra™ in conjunction with a Lasik enhancement if one is required.
Are there any limitations or restrictions as to what I can do after Lasik Xtra™?
The only limitations are those your doctor recommends following standard Lasik, there are no special, separate recommendations regarding Lasik Xtra™.
Can anyone tell by my appearance that I have had Lasik Xtra™?
No. An eye treated with Lasik Xtra™ cannot be differentiated from the normal appearance of an eye treated with Lasik only.
How many people have undergone a Lasik Xtra™ procedure?
More than 50,000 Lasik Xtra™ procedures have been performed.
Can both eyes receive Lasik Xtra™?
