Wavefront Technology for LASIK
How WaveScan WaveFront« Works
WaveScan WaveFront« technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. Using this technology, Dr. Davis can detect and measure the optical distortions unique to you entire optical system.
Light travels in a procession of flat sheets known as wavefronts. Gentle wavefront lights enter the eye, pass through the entire optical system (cornea, lens and retina) and are then reflected back into the WaveScan sensors.
The WaveScan system compares the reflected wavefronts with the original unaltered wavefronts. This produces a fingerprint of your vision, or WavePrint™ map. This information is then transferred to the VISX STAR S4™ excimer laser and is used as a guide to reshape the cornea during your laser vision treatment.
Great Results by Day and by Night
In the past, laser vision correction patients have occasionally complained about their night vision. Of course, these symptoms can even be present in people without LASIK whose vision is corrected with glasses or contact lenses. However, in the CustomVue FDA clinical study, more people were satisfied or very satisfied with their night vision after their CustomVue LASIK as compared to their prior level of satisfaction using glasses or contact lenses.
One year after the CustomVue procedure, patients in a clinical study reported these great results without glasses or contact lenses:
• 100% could pass a driving test
• 98% could see 20/20 or better
• 70% could see better than 20/20
Although no individual surgical outcome can be guaranteed, these clinical studies, nevertheless, show the extraordinary effectiveness of this exciting new technology.
Laser Vision Procedures
Laser Vision Correction was first performed using a procedure called Photo-Refractive Keratectomy or PRK. PRK has undergone much advancement since 1995. Vision correction with PRK is accomplished by removing tissue from the surface of the cornea.
Laser in-Situ Keratomileusis, or LASIK, is the most popular form of laser vision correction and corrects vision by removing tissue from the inner cornea. Making a corneal flap and then reshaping the inner tissue provides a more rapid return of functional vision and less post-operative discomfort.
On the day of the procedure, anesthetic drops are placed into the eye. If the patient is a candidate for CustomVue, their unique correction information is transferred from the WaveScan to the VISX STAR S4™ excimer laser and guides the laser throughout the procedure.
Often, in less than a minute, the cool beam from the laser gently reshapes the cornea, removing microscopic amounts of tissue - less than the thickness of a human hair in most cases - to create a new curvature. During the procedure, the 3D ACTIVETRAK™ eye tracker follows the eye's tiniest moves. It automatically repositions the laser to keep the laser beam focused where the doctor wants it, so one can completely relax during the procedure.
Many patients notice immediate results after CustomVue with their vision continuing to improve over several days. Routine follow-up visits complete the process. VISX lasers have been used to perform millions of laser vision correction procedures in the U.S. and around the world. Every year, more doctors use VISX lasers to perform laser vision correction than any other system.
