The most significant breakthrough in laser vision correction surgery is the invention of blade-free technology by IntraLase. The first step in LASIK is the creation of a flap in the cornea. In the past, a blade was used. With IntraLase, there is no need to use a metal blade. Instead, pulses of laser light are applied into your cornea at the exact depth and position. Small bubbles measuring one ten-thousandth inch in diameter are created. The laser is passed across the cornea, and a corneal layer made up of thousands of bubbles is formed.

IntraLase is the name of the new and exciting technology that is utilized to perform LASIK without a blade, or IntraLASIK. The corneal flap is created from the inside-out, at a depth and position that has been pre-programmed. To prevent the eye from moving while IntraLase is performed, it is first fixated with a low pressure soft suction ring. Then, the laser is passed through it and after less than a 30 seconds, bubbles of carbon dioxide and water are formed in the cornea. The bubbles create a surface that is smooth. To create the corneal flap, the doctor gently separates the tissue where the bubbles have formed, following the natural divisions that are found in the cornea. After this, laser vision correction is applied. Then, the doctor completes the LASIK treatment by folding back the flap.

The IntraLase has a 3-micron laser spot size that can create a flap that is customized at excellent accuracy. Because of the amazing accuracy of the device, many people who were disqualified for LASIK have been successfully treated without any damage on the surrounding tissues or without deformation of the curvature of the cornea.

The use of IntraLase minimizes the dangers of having complications like corneal abrasion, thin flap, thick flap, partial flap, incorrect diameter, or buttonhole flap, which happened more with traditional microkeratome usage in bladed-lasik. Also, the flap made using IntraLase has a different shape compared to the one created using the microkeratome. Through IntraLase, a flap that has the same thickness and which has vertical edges is created. This “manhole”shaped flap prevents problems like slippage or wrinkling of the flap when it is rubbed or bumped unintentionally during the healing period after surgery. Using IntraLase will ensure a safer and more accurate treatment for any kind of prescription.
