LASIK QUESTION OF THE DAY: What about Bladeless LASIK?
There are many types of Laser Eye Surgery for the correction of nearsightedness, farsightedness and astigmatism. LASIK is the most common type. It is a three-step procedure. First you create a thin layer of tissue in the cornea that can be lifted. Second you apply the laser energy to the underlying corneal surface to reshape it and actually perform the Laser Vision Correction. Third and last, you replace the "flap" and it adheres to the exposed treated corneal surface.
Step one can be performed either using a precise mechanical instrument, called a microkeratome, to create the flap-or the flap can be created using a femtosecond laser. When the flap is created with the laser the procedure is referred to as a Bladeless LASIK procedure or an All Laser LASIK procedure. The literature regarding which is better indicates that both the microkeratome and the laser are equally effective for creating the LASIK flap.
