“Cross-linking within a LASIK procedure using Lasik Xtra is simple, fast and safe,” said A. John[...]

Lasik Xtra is a simple treatment performed in conjunction with Lasik that adds just a few extra minutes to the Lasik treatment and requires no extra doctor visits. In a few minutes, during your Lasik procedure, Lasik Xtra will add biomechanical strength to your cornea, enhancing the power of Lasik by helping you see better for longer.

Lasik Xtra uses Ultraviolet A (UVA) light and riboflavin (vitamin B) eye drops to strengthen the cornea.

Ultraviolet A (UVA) is one of the three types of invisible light rays given off by the sun (together with ultraviolet B and ultraviolet C) and is the weakest of the three.

Riboflavin (vitamin B) is important for body growth, red blood cell production and helps in releasing energy from carbohydrates.  Its food sources include: Dairy products, eggs, green leafy vegetables, lean meats, legumes, milk nuts. Breads and cereals are often fortified with riboflavin.


The Lasik Procedure:

After numbing drops are applied to your eye (1), a “flap” is created in the cornea, the clear window of your eye, (2 and 3) using either a microkeratome (shown) or a femtosecond laser. The surgeon then lifts the flap (4), and an excimer laser is then used to reshape the underlying cornea to change the way the light is focused (5), correcting near-sightedness (myopia) or far-sightedness (hyperopia). The Lasik procedure is now finished.

The Lasik Xtra Procedure:

After the excimer laser, riboflavin eye-drops will be placed on the corneal bed and will soak for one to two minutes (6).  After the soaking time, your doctor will rinse off excess riboflavin and close the corneal flap (7).  The UVA light will be aligned over your eye, and the light will be turned on for just over a minute.

That’s it!  Both procedures are finished.  You can now go home and “See Strong!”  Click here to learn Why Lasik Xtra
