How LASIK Surgery Became Bladeless

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).
