Femtosecond laser LASIK features laser light pulses
Traditionally, doctors have used an instrument called a microkeratome for the creation of corneal flaps. The microkeratome is a hand-held blade that moves across the eye, cutting the corneal flap as it goes. While LASIK is extremely safe, if complications do occur, the microkeratome is most often the cause. By contrast, this enables your doctor to create your corneal flap without a blade ever touching your eye.
Laser light provides precision, efficiency
The IntraLase uses rapid pulses of laser light to create a layer of bubbles under the surface of your eye, making a corneal flap. The exact dimensions of this layer of bubbles are determined by your doctor based on what is best for your eye, and are computer controlled for maximum precision – things that are not possible with a hand-held blade. The femtosecond laser flap creation process takes about 20 seconds.
When it is time for your LASIK treatment to be performed, your doctor easily separates the tissue where these bubbles occur and then folds it back, thus creating your corneal flap. When LASIK is complete, a flap created using the femtosecond laser is uniquely able to “lock” back into place. Your eye then begins to rapidly heal.
Patients prefer Femtosecond laser for LASIK
Outstanding visual results: more patients achieve vision that is 20/20 or better. And patients report better quality of vision overall, particularly in terms of their ability to see well in low light, such as at dusk or at night.
In a clinical survey of LASIK patients who had their corneal flaps created using a blade in one eye and the femtosecond laser in the other, the vision in the femtosecond laser-treated eye was preferred 3-to-1 among those who stated a preference.
The Femtosecond laser LASIK is the only type of LASIK approved by NASA and all branches of the US military, including navy pilots.
Ultimately, the 100 percent blade-free femtosecond laser gives patients more confidence and less anxiety going in for LASIK treatment and excellent vision coming out.
Common vision disorders such as nearsightedness, farsightedness and astigmatism are known as lower order aberrations. These disorders are usually correctable with glasses, contact lenses or conventional LASIK surgery. However, research has shown that visual disturbances that affect the quality of vision, such as glare, halos and other distortions are linked to higher-order aberrations.
Advanced CustomVue™ is the newest and most advanced technology available that allows physicians to measure and address higher order aberrations that previously could not be detected. We can measure these in your eye using WaveScan™ technology. This virtual map is specific to the individual’s unique optical distortions. This virtual map in turn is electronically transferred to the laser, which then delivers a more precise correction to your eye.
