How IntraLase laser Works

Unlike the microkeratome blade, which cuts across the cornea to create the flap, IntraLase laser doesn’t traverse the cornea; in fact, it never touches the outer cornea but rather creates the flap using an “inside-out” process, virtually eliminating severe sight-threatening complications as a result.

  • The INTRALASE® FS laser uses an infrared beam of light to create the flap from below the surface of the cornea.
  • The beam of laser light is focused to a precise point within the stroma (central layer of the cornea), where a string of tiny 2- to 3-micron bubbles is formed.
  • Thousands of these microscopic bubbles are precisely positioned to define the flap’s dimensions and distinct beveled edge, as well as location of the hinge.
  • Bubbles are then stacked along the edge of the flap up to the corneal surface to complete the flap.
  • The process from start to finish takes approximately 45 seconds
  • The laser eye surgeon then lifts the flap to allow for treatment by the excimer laser. When treatment is complete, the flap is accurately repositioned, thanks to its beveled edge.

      • With IntraLase laser, the eye surgeon can precisely control the critical first step of LASIK surgery.Pre-programmed laser specifications include flap diameter, depth, hinge location and width, and side-cut architecture – factors which may vary by patient. IntraLase flaps also feature a distinctive beveled edge, which allows for precise repositioning, alignment and seating of the flap after LASIK surgery is completed. This ability to personalize specific parameters is impossible with a microkeratome or other hand-held bladed instrument.

      Lasik Eyes IntraLase laser is the most sophisticated and accurate technology for corneal flap creation available today, and has given patients greater confidence in choosing vision correction surgery. The higher degree of assurance and safety, virtually no risk of severe sight-threatening complications, and more predictable outcomes have been shown to increase patient satisfaction in their LASIK experience and outcome.
