WaveFront guided laser vision correction begins by using a device called a WaveScan. Chicago Lasik Surgery has improved with this device. Wavefront guided laser surgery has been FDA approved for nearsightedness, farsightedness and astigmatism in low to moderate amounts and the results are excellent. We test all patients prior to laser surgery with both a VISX wavescan and a Nidek wavescan prior to lasik surgery.

This is a device that measures imperfections in the visual system that is unique to each individual. This technology was originally developed for use in telescopes such as the Hubbel space telescope to reduce distortions when viewing distant objects. This same technology has now been applied to laser vision correction. WaveScan technology identifies and measures imperfections in an individual’s vision 25 times more precisely than standard methods used for glasses or contact lenses.

The WaveScan produces a WavePrint™ map which is a visual representation of how a patient’s optic system processes light. This map is like a fingerprint and is unique to each individual patient.

The WavePrint™ map is printed out for each patient to see if he or she is a candidate.

If a person is a candidate this map is then copied to a disc and directly inserted into the VISX Star-4ä laser. The laser has an ActiveTrak™ 3-D eye tracker that uses an infrared camera to actively follow the tiniest motion of the eye in all directions. This allows the patient to rest during the procedure knowing that the laser system is actively following eye movement to ensure greater precision and accuracy during treatment.
