The LenSx Method is a 100% blade-free approach to creating your LASIK flap — the thin flap of tissue that the doctor folds back in order to perform your LASIK procedure. The LenSx Method can only be performed using the Femtosecond Laser. 

Traditionally, doctors have used an instrument called a microkeratome for the creation of LASIK flaps. The microkeratome is a hand-held blade that moves across the eye, cutting the LASIK flap as it goes. LASIK is extremely safe, but if complications do occur, the microkeratome is frequently the cause. The LenSx Method, by contrast, enables your doctor to create an individualized LASIK flap without a blade ever touching your eye. 

With the LenSx Method, tiny pulses of laser light, a quadrillionth of a second each, pass harmlessly through the outer portion of your cornea and form a uniform layer of microscopic bubbles just beneath the surface of your eye.

The exact dimensions of this layer of bubbles are determined by your doctor based on what’s best for your eye, and are computer controlled for maximum precision — things that are not possible with a handheld blade. The IntraLase flap creation process takes about 15 to 20 seconds per eye and a total of 10 minutes for the entire LASIK procedure. 

When it’s time for your LASIK treatment to be performed, your doctor easily lifts the flap to apply the LASIK treatment. When LASIK is complete, a flap created using the LenSx Method is uniquely able to “lock” back into place. Your eye then begins to rapidly heal.
