The most common laser and surgical vision correction procedure performed today is LASIK (Laser in-situ Keratomileusis). In LASIK, a surgeon combines the use of a microkeratome and the excimer laser. The microkeratome is a very precise surgical instrument, which is used to create and lift a thin flap of corneal tissue. When this flap is lifted, the surgeon uses the laser to reshape the underlying corneal tissue (the stroma) and correct the nearsightedness, farsightedness and/or astigmatism. The flap is then placed back over the cornea and heals quickly without stitches. LASIK is our procedure of choice in most cases because it does not alter the surface of the cornea. This promotes faster healing and less chance of scarring or discomfort after the procedure.
