"Map Becomes Guide for Treatment"                         

Until recently, laser vision correction, like glasses or contacts, could only correct the visual distortions caused by nearsightedness, farsightedness, and astigmatism.  But, these distortions are only responsible for 85-90% of the overall quality of your vision.

 

Thanks to advancements in wavefront technology, it is now possible to measure and address visual distortions throughout your eye's entire optical system.  The procedure is called CustomVue.  Using your unique WaveScan wavefront map as a guide, the Visx Star S4 with Iris Registration Excimer Laser reshapes your cornea in the exact pattern defined by your map.  Visx's radar eye tracker tracks the eye movement while it guides the small spot laser beam with extreme accuracy.

 

 Although conventional laser vision correction can produce excellent results, CustomVue has the potential to deliver even better results by improving the quality of your vision.

 

 

The Custom treatment is accomplished by taking a "wavefront" measurement of the eye.  A light is flashed into the eye and the reflected light is passed through a grid with about 200 spots.  These individual spots are analyzed and a unique prescription of each spot is converted to a prescription map of the eye.  All the subtle spots, peak and valleys are converted to a treatment map.  This individualized map is converted to a treatment protocol that the laser uses to treat the eye. 

 

 

 

 

 

 

One more important component is the Iris Registration.  When the wavefront map of the eye is measured, the exact location of the map relative to the surrounding structures must be noted.  The eyes may rotate inward or outward with lying down (cyclotorsion).  With the Iris Registration, a photograph of the Iris is taken at the same time as the wavefront measurement.  Up to 25 unique spots on the iris are identified and when the patient is undergoing the laser, these spots are sought by the laser.  When the spots are identified, the map rotates to match the exact same location where the wavefront belongs.  Therefore, the iris registration has brought the CustomVue treatment accuracy to a new height.
