Instead of using a surgical blade as in traditional LASIK, the "all laser" IntraLase eye surgery still cuts the cornea with a laser and still involves a flap. Intralase (bladeless LASIK) has claimed a reduced risk of intraoperative flap complications of the old LASIK because the laser is programmed to cut the cornea at a precise thickness. However, the risk of having flap related complications is not eliminated because it is not possible to eliminate this problem when the flap itself is still present.
The newer LASEK laser eye surgery does not involve cutting and is a non-flap procedure, which means it eliminates LASIK flap complications. With this new breakthrough, it is undisputable that the no-cuts, no-flaps LASEK eye surgery is so far the safest laser vision correction.
