Blade-Free LASIK technology is trusted by NASA.
The Blade-Free LASIK procedure represents the most widely researched vision correction technology available today. More vision corrections are performed worldwide with Blade-Free LASIK technology than with any other laser procedure. Blade-Free LASIK has earned FDA approval to correct the broadest range of vision imperfections, including mild to severe nearsightedness, farsightedness, and all types of astigmatism. It combines the world’s most advanced technologies into one all-laser procedure that reduces the risk of complications. The safety and effectiveness of Blade-Free LASIK is so trusted that NASA and all branches of the U.S. military have approved Blade-Free LASIK for their service men and women.
Blade-Free LASIK: During the Procedure
Advanced CustomVue Technology
Your Advanced CustomVue treatment is designed to correct the unique imperfections of your vision. The Wavescan identifies and measures imperfections in an individual’s eye 25 times more precisely than the standard methods used for glasses and contacts. Wavefront guided LASIK offers the broadest range of FDA approvals. This means more than 94% of the eligible population 21 and older are potential candidates for the Advanced CustomVue treatment.

Blade-Free LASIK: Creating the Flap
VISX Unique 3-Dimensional Eye Tracking
- Follows all eye movements: up and down or side to side
- Checks placement 6x per pulse
- Has both active and passive tracking
- The digital information is transferred to the Excimer Laser which performs the LASIK procedure
The only other way to create a corneal flap is with an instrument called a microkeratome—a hand-held steel blade that makes a cut in the cornea. With Blade-Free LASIK, a blade never touches your eye.
Tiny pulses of laser light pass harmlessly through the outer portion of your cornea and form a uniform layer of microscopic bubbles beneath the surface of your eye. Just prior to LASIK surgery, your doctor lifts the corneal flap by gently and easily separating the tissue where the bubbles have formed.
Blade-Free LASIK virtually eliminates the most severe sight-threatening complications. While LASIK complications are rare, when they do occur they are primarily related to the use of the microkeratome. The IntraLase Method is 100% blade free and has been shown to improve outcomes for more patients (citation #1), with better vision quality overall, particularly in low light (citation #2)
IntraLase technology has been in existence since 2001. To date, it has been used in millions of LASIK procedures around the world.
A clinical survey showed that, among those with a preference, LASIK patients preferred the vision in the IntraLase-treated eye 3-to-1 over the vision in the microkeratome-treated eye (citation #3).
Including preparation time, the procedure takes about 10 minutes per eye. Of that, creation of the corneal flap takes 15 to 20 seconds per eye. Prior to creating the flap, your surgeon administers drops to numb the eye, then applies a special instrument that gently flattens your cornea in preparation for the procedure. Most patients report feeling only slight pressure. Learn more…
