INTRODUCTION


LASIK eye surgery has become the most popular refractive procedure of all time and is the vision correction procedure of choice for refractive surgeons the world over. LASIK combines the precision of the excimer laser delivery system with the benefit of a sophisticated surgical instrument known as a microkeratome. LASIK eye surgery is performed under anesthetic eye drops. The microtome is used to create a thin corneal flap, which is opened like the page of a book. The excimer laser is then used to sculpt ultra-thin layers of the remaining cornea to change its shape.
By changing the shape of the cornea, treatment of nearsightedness, farsightedness, and/or astigmatism is possible for the appropriate eye. After the laser treatment, the flap is returned back to its original position and adheres without the use of stitches. The entire procedure takes less than 15 minutes for both eyes. There are two types of LASIK eye surgery, Standard LASIK and Custom LASIK (also known as Wavefront-guided LASIK).
