                 Preparing for Surgery
  | 
              While in the past, changing the focusing power of the eye could only be accomplished with glasses or contact lenses, these surgical techniques have allowed for a permanent change in the eye, often resulting in the elimination of the need for glasses or contacts.  |      |  
      
        
            
              The field of vision correction surgery is still rapidly changing, with new techniques and new applications for this surgery expected in the near future.  |

              PhotoRefractive Keratectomy uses a laser to reshape the cornea, the front surface of the eye, in order to change it's ability to focus light on the retina.  |      |  
      
        
            
              LASIK, or Laser ASsisted In-situ Keratomileusis, is a variant of excimer laser photorefractive keratectomy.  |

                    ICRS - Intrastromal Corneal Ring Segments (INTACS)  are now the First FDA-Approved Non-Laser Surgical Product that is a New Option For Treating 22 Million Nearsighted Americans. |      |      |  
      
        
            
              Radial Keratotomy, or RK, changes the shape of the cornea by making incisions with a surgical knife to flatten, steepen, or alter the contour of the front of the eye.  |
