The VISX Advantage

Visx Star S4 with CustomVue and ActiveTrak

Dr. Tim Khater is pleased to add the premier IntraLase laser to the LASIK procedure. The IntraLase laser replaces the microkeratome blade in creating a uniquely safe and uniquely precise corneal flap in the first step of the LASIK procedure. IntraLase makes Custom LASIK an all laser, no blade procedure.


He uses the highly preferred VISX Star S4 excimer laser exclusively to perform all LASIK procedures. The VISX WaveScan is performed with all LASIK evaluations in preparation of CustomVue treatment for both nearsighted and farsighted Custom candidates.


The VISX Star S4 utilizes a 3-D Active Trak system, which locks the laser into position on the cornea ensuring accuracy in treatment even if movement of the eye occurs. Unlike other systems, with Active Trak the doctor does not have to dilate your pupils resulting in a comfortable, quicker recovery time of a non-dilated pupil. Seven variable-sized beams give the doctor greater flexibility and allow for faster, smooth, precise corneal treatment. The treatment zone is wider than almost all pupils and is the only laser with computerized centration. This may dramatically decrease the incidence of glare and halo after LASIK eye surgery.


This excimer laser was the first in the United States to receive approval from the FDA for the treatment of low, moderate and high myopia (nearsightedness), low to moderate ranges of hyperopia (farsightedness), and astigmatism. With the new Wave Print VISX technology, CustomVue treatment is now available for both myopia and hyperopia Custom candidates. IntraLase Custom LASIK technology allows even better opportunity to achieve one�s personal best vision correction.

Patented Eye Tracking System detects all relevant eye movements and repositions laser beam to match movements.



“The Fingerprint of Your Vision�”
Because no two eyes are alike, each eye has a unique map, or fingerprint. “The Fingerprint of Your Vision” defines unique characteristics in each individual’s vision and is produced by WaveScan� technology.

WaveScan Technology, originally developed for use in high-powered telescopes to reduce distortions in space, has now been adapted for eyecare. A single beam of infrared laser light is passed into the eye and focused on the retina. The light is then reflected off the retina, passed back through the eye, through a lenslet array to a sensor, and then analyzed from 200 different aspects to create a map of the eye – or fingerprint of vision. This technology uncovers unique characteristics of the eye never measured before using standard methods for glasses and contact lenses.

The CustomVue Procedure

On procedure day, you will be seated in a reclined position. Anesthetic drops will be placed in your eyes and a flap will be created on your cornea. Your individualized treatment information is transferred from the WaveScan to the laser in order to drive the CustomVue procedure. The actual laser procedure typically takes several seconds. The majority of individuals feel no pain during the procedure. After CustomVue, you will notice results immediately, and your vision will continue to improve over the next few days. You will be scheduled for a follow-up visit the next day, and again several weeks after the initial procedure.
