How does the IntraLase laser work?

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.

Advantages Of Intralase

Improved Safety : Eliminates the most severe microkeratome-related complications, including invasive corneal incisions and button-hole flaps. Lasik Eyes

Better Vision : Patients achieve statistically better vision when IntraLase laser is used in the LASIK procedure. In comparison with microkeratome-initiated LASIK, more patients achieved 20/20 vision and those with a preference preferred the post-operative vision of their IntraLase treated eye 3-to-1. Lasik Eyes

Highest Degree of Predictability and Precision : Micron-level precision creates significantly more predictable and accurate flap dimensions, including, most critically, reproducible flap thickness, within ± 10 microns, whereas variability with microkeratomes has been reported up to ± 40 microns. This increased precision preserves valuable corneal tissue and improves the predictability of the LASIK treatment. Lasik Eyes

Fewer Retreatments : The number of LASIK retreatments (or enhancements) is significantly lower for laser-created corneal flaps, avoiding the patient inconvenience of subsequent surgeries and the increased surgeon costs entailed with re operations. Lasik Eyes

Reduced Dry Eye Symptoms : In several clinical studies, standard tests performed to diagnose dry eye show a significant reduction in symptoms, the largest of which shows patient symptoms were reduced by 72 percent. This lower occurrence of dry eye symptoms may be due to the uniform and typically thinner flap, creating less disruption of nerves in the cornea.

Individualized Flaps : The laser flap can be tailored to the individual patient’s needs, allowing physicians to individualize all steps in the LASIK laser eye surgery LASIK laser eye surgery procedure: custom diagnosis with wavefront; personalized flap creation with IntraLase, and, custom laser treatment with custom ablation.
