When the word surgery is thrown around, it is only natural to associate cutting with scalpels or needing stitches because that is how surgery is done a majority of the time. However, when it comes to LASIK eye surgery the story is not quite the same. Thanks to a company called IntraLase that created the first femtosecond laser to be approved by the FDA in 2001. The significance of the FDA approval meant that it was no longer necessary to use a surgical blade of any kind in laser eye surgery.
During laser eye surgery, the eye surgeon uses two highly specialized lasers to correct the patient’s vision impairments. The first laser, called a femtosecond laser, is used to create the thin flap in the cornea by ultra-short pulses of laser light and then the flap is folded back. This then allows the inner cornea to be reshaped by the second laser, an excimer laser, to correct the vision impairments. Once the corneal tissue has been reshaped, the flap is then returned to its original place for healing.
Prior to FDA approval of the femtosecond laser, surgeons would use a blade called a microkeratome on patients who wished to undergo Lasik surgery. Some of the advantages that come from surgeons being able to use the femtosecond laser in Lasik eye surgery are:
- Consistent corneal flap thickness and better fit for healing
- Lower risk of corneal abrasions during surgery
- Lower risk of induced astigmatism after Lasik
Also, the surgeon may make it possible to create a thinner flap, which would allow for a higher amount of correction of nearsightedness. The laser allows for a more customized surgery that better fits each patient individually (flap size, thickness, shape, orientation).
