IntraLase initiated LASIK (http://www.intralase.com) is an advanced new technology designed to create a corneal flap. With the IntraLase laser, the surgeon can precisely control the first step of Custom LASIK. The surgeon can program this laser to meet the individual patient’s needs. This precision allows surgeons to treat some patients once not considered to be LASIK candidates.
There are two steps in the LASIK procedure. First, the surgeon creates a micro-thin corneal flap, which is then lifted to expose the inner cornea for the second step, vision treatment by an excimer laser.How Intralase Works
Pulsing at a speed of one-quadrillionth of a second, the ultra fast IntraLase FS “femtosecond” laser uses an
infrared beam of light to prepare the intracorneal bed and create the flap, using an “inside-out” process to complete the first step of LASIK. - The beam of laser light is focused to a precise point within the cornea where a string of microscopic bubbles is formed.
- Thousands of these tiny bubbles are precisely positioned to define the architecture of the intracorneal surface, as well as the distinct beveled edge of the resulting flap.
- Bubbles are then stacked along the edge up to the corneal surface to complete step one.
- The IntraLase process from start to finish takes approximately 30 seconds.
- The physician then lifts the flap to expose the prepared corneal bed for treatment by the excimer laser treatment (the second step of LASIK).
- The LASIK procedure is completed when the flap is securely repositioned.
