Customised Treatment Procedure

Wavefront technology was pioneered in the fields of physics and to aid in reducing 'aberrations' or imperfections with the complex optical systems of telescopes. Similarly, we use the ultra-precise Tscherning wavefront aberrometer to provide us with an accurate assessment of the optical imperfections throughout the optical system of the human eye.

At Focus Laser Vision we utilize wavefront technology to measure and address both lower and higher order aberrations (visual imperfections in the eye's optical system). Unless both lower and higher order aberrations are addressed during laser vision correction, the quality of your vision may not be ideal, even if you have post-operative vision of 20/20.

Here is how this exciting technology works:

First, a grid pattern of rays of light are passed through your eye using a computerized wavefront measuring instrument (the WaveLight Analyzer) made by WaveLight AG. As the light waves travel through your eye's optical system, the imperfections in the eye distort the grid pattern. The Analyzer captures the image of the grid pattern on the retina at the back of the eye, and then calculates the imperfections within the eye by how much the grid has been distorted from a perfect arrangement.

Next, a three-dimensional map is produced representing your unique visual distortions, including both lower and higher order aberrations. This map is then transferred to the WaveLight Allegretto Wave excimer laser, and guides the laser as it reshapes your cornea, providing you with a perfectly customized laser vision procedure.
