LASIK is a refractive surgery performed by ophthalmologists to correct refractive defects. Many patients choose LASIK as an alternative to wearing corrective eyeglasses or contact lenses, that’s why it has become the most commonly performed refractive surgery procedure.
With nearsighted people, the goal is to flatten the too-steep cornea. With farsighted people, a steeper cornea is desired. Astigmatism is corrected by smoothing an irregular cornea into a more normal shape. To remove the corneal tissue and reshape the cornea, the surgeon uses an excimer laser.
Why is LASIK so popular? Because there is a relative lack of pain afterward and good vision is usually achieved by the very next day. More than 17 million people worldwide have had LASIK or other laser refractive surgery. The number of laser vision correction procedures performed annually in the United States has remained relatively unchanged: approximately 1.3 million procedures were performed each year in 2004, 2005 and 2006, and it was estimated that another 1.3 million would be performed in 2007 (TLC Vision Corp. 2006 Annual Report).
