Intralase™ uses tiny, rapid pulses of laser light to create the corneal flap during the first step of LASIK. Each pulse of light passes through the top layers of the cornea and forms a microscopic bubble at a specific depth and position within your eye that is determined by your surgeon. Blade-free LASIK allows some patients who were previously ineligible for laser eye surgery to have the procedure. A thin cornea may disqualify some persons interested in LASIK, however with blade-free technology, a thinner flap is possible, thus allowing many persons with thin corneas to now have laser vision correction. Also, a flap that is individualized to each patient can result in better postoperative outcomes. More patients in clinical trials achieved 20/20 or better vision when their procedure was performed using Intralase. Patients also report better quality vision overall, particularly in terms of their ability to see well in low light, such as at dusk or at night.
