The IntraLase ultrafast femtosecond laser uses bladeless laser technology for
performing Step One of LASIK and is the most accurate technology for corneal flap
creation available today. The laser uses an infrared beam of light to precisely
separate tissue through a process called photodisruption. In this process, the
focused laser pulses divide material at the molecular level without the transfer
of heat or impact to the surrounding tissue.
- The silent beam of laser light is focused to a precise point within the stroma
(central layer of the cornea) where each pulse of the laser creates a tiny 2-
to 3-micron bubble of carbon dioxide and water vapor.
- Thousands of these microscopic bubbles are precisely positioned to define the
flap’s dimensions, as well as the location of the hinge.
- The process takes approximately 18 seconds.
- Dr. Parker then lifts the flap to allow for treatment by the excimer laser (VISX
Star 4 Custom Wavefront).
- With IntraLase, Dr. Parker can create a corneal flap of exact diameter, depth,
hinge location, centration, and overall architecture.
