Before Femtosecond Technology lasers, step one of the Laser Vision Correction process could only be accomplished with a mechanical device called a microkeratome.
The IntraLase® ultrafast femtosecond laser was the first bladeless laser technology for performing Step One of LASIK and was originally developed by Harvard physicists. This 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.
- IntraLase® creates the flap from below the surface of the cornea, using an “inside-out” process.
- 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.
- 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 22 seconds.
Millennium Laser Eye Centers is proud to offer the IntraLase Technology to those patients who would medically benefit from the access that this laser technology provides.
