The technology behind the miracle of laser vision correction
Thursday, June 10th, 2010We thought this week that we’d take a closer look at the technology we use here at Image Plus Laser Eye Centre to help hundreds of Manitobans live a more fulfilling life without the need for glasses or contact lenses.
Originally developed to measure optical distortions inherent in powerful telescopes, Wavefront technology has now been adapted to laser vision correction.
The WavePrint System™ by VISX® uses Fourier WaveFront sensing technology. This technology is exceptionally good at measuring subtle variations in high order distortions (e.g. spherical aberrations, coma). The system creates an incredibly detailed and accurate wavefront map of the eye. This map is as unique as your fingerprint or DNA sequence.
Diagnosis
The first step toward improving your vision through laser eye surgery is the assessment. The Advanced CustomVue Wavefront technology allows a higher level of diagnosis and treatment than traditional diagnosis methods. The VISX WavePrint map that is produced using this method shows the surgeon how light focuses in different areas of the eye, allowing the doctor to decide whether you are a good candidate for Advanced CustomVue™ WaveFront laser vision correction.
It also allows the doctor to determine the accuracy of your current glasses prescription and to personalise your laser treatment plan to your eye’s unique vision distortion.
Treatment
VISX® Star S4 Advanced CustomVue™ WaveFront laser vision correction is performed with The WavePrint System™. This system includes:
* The WavePrint Map
* 3D ActiveTrak™ Eyetracker;
* Variable Spot Scanning (VSS™)
* Iris Registration (IR™)
Your surgeon is then afforded the opportunity to personalize your treatment in accordance with the Wavefront map. This technology also allows the surgeon to track any minute movement your eye makes during the surgery, via the 3D ActiveTrak™ Eyetracker, across all three dimensions. The machine repositions the laser in real time to compensate for these movements, ensuring the accuracy of the application of the treatment.
The VISX® S4 Variable Spot Scanning (VSS™) allows for more accurate reshaping of the eye based on your personal Wavefront profile.
VISX® Iris Registration (IR™) is the newest component of Advanced CustomVue™ WaveFront. It allows far greater accuracy for the surgeon, and accounts for the rotation that occurs in our eyes when we move from a sitting to a lying position.
We chose our technology carefully to ensure that we are providing the best possible treatments and outcomes for our patients.
