| What is an IntraLase® laser ? |
|
 The IntraLase® laser is the first bladeless laser technology that can be used to perform the necessary first step required all standard and custom LASIK vision correction procedures - thecreation of the corneal flap. This accurate laser technology eliminates the need for the surgeon touse a hand-held cutting tool with an oscillating blade called a microkeratome to make the flap.The IntraLase® laser focuses 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. |
 |
|
Comparative clinical studies confirm that IntraLase® offers benefits beyond predictably better vision. At follow up exams, more patients prefer their vision and see better following laser vision correction with Intralase than with previous methods. By bringing IntraLase® into our practice, not only are we are taking patient safety to the highest level available but we're also raising the bar for quality vision results. |
 |
This important technological breakthrough is already revolutionizing the laser eye surgery. But IntraLase® is just the latest investment Yonge Eglinton Laser Eye Centre has made to provide you with quality results and true value. |

Why does the IntraLase® laser offer faster healing, greater comfort and better
vision ? |
|
 During the first step of any standard or custom LASIK eye correction procedure, the surgeon must first create a corneal flap. Achieving accurate depth, flap thickness, and centration on a curved cornea of varying dimension can be difficult with a hand-held cutting tool. The precision of this step is highly dependent upon the performance of the microkeratome device and the skill of the surgeon.
The IntraLase® laser is a more precise and safer method for creating the flap. Computer-guided, the IntraLase® laser offers a more precise means of creating the flap and removes the unpredictability of using a hand-held cutting tool and surgeon capability making both standard and custom LASIK surgeries better.
By using a computer-controlled, laser approach to flap creation, LASIK eye surgery is safer than ever before. The use of the IntraLase® laser delivers micron-level accuracy 100 percent greater than a microkeratome for more accurate and consistent flap thickness, factors critical for a successful LASIK outcome.
The use of a microkeratome for the creation of the corneal flap has always been safe and generally provides good results in LASIK eye surgery. However,the degree of accuracy achieved by the IntraLase® laser is unprecedented in flap creation technology.
With the IntraLase® laser you now have the greater assurance need that your LASIK eye surgery results will be more accurate and safer. |

| How is the IntraLase® laser used by the surgeon ? |
|
 |
Every corneal flap is different. But there are certain characteristics that every flap must have, including precise diameter, centration and thickness, thereby setting the stage for your doctor to complete the laser eye correction and provide you with a superior vision result. |
|
The surgeon uses the IntraLase® laser to create the corneal flap from below the surface of the cornea, using an "inside-out" process. |
|
A 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 45 seconds.
The surgeon then lifts the flap to allow for treatment by the excimer laser to complete the LASIK procedure. When treatment is complete, the flap is repositioned. |
|
The IntraLase® laser allows your surgeon to create a corneal flap of exact diameter, depth, hinge location, centration, and overall architecture. Such accuracy and precision are nearly impossible in a hand-held blade.

Who is the company behind the IntraLase® laser ?
Founded in 1997, IntraLase Corp. (NASDAQ:ILSE) is located in Irvine, California. The company's IntraLase® FS laser uses proprietary, computer-guided femtosecond laser technology for greater precision, improved safety and better results as compared to the use of traditional microkeratomes to create a corneal flap in Step One of LASIK eye surgery.
Although LASIK eye surgery has a long history of safely and effectively improving vision and lessening patients' dependence on glasses and contact lenses, IntraLase, saw a way to make LASIK surgery safer and more effective. The company developed breakthrough technology that replaces the mechanical microkeratome with a highly precise laser that works at the molecular level to separate tissue and create a superior corneal flap.
This innovation made sense. Lasers have a long history in medicine. In fact, the excimer laser used in Step Two of LASIK surgery has brought incredible safety and precision to eye surgery. One pulse of
the excimer laser removes 0.25 microns of tissue, which is almost 300 times thinner than a typical
human hair.
The IntraLase® laser actually represents a breakthrough in the field of ultrafast laser science. Generating light pulses as short as one-quadrillionth of a second, femtosecond laser technology has opened new fields of scientific study and provided the basis of femtochemistry research that won the 1999 Nobel Prize in Chemistry.
The use of the femtosecond laser in the field of ophthalmology was developed by a team of physicists, biomedical engineers and ophthalmologists at the Center for Ultrafast Optical Sciences and the Kellogg Eye Center of the University of Michigan.
