Wavefront-Guided LASIK: The New Frontier

/24-7PressRelease/ - April 11, 2007

Wavefront-guided LASIK uses Wavefront technology to customize the surgery precisely to your eyes. Traditional LASIK and corrective lenses can correct common vision problems including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, but cannot address other problems with quality of vision. Higher order aberrations can cause vision problems such as halos, glare, decreased contrast sensitivity, and shadows. These problems normally do not affect visual acuity (how you test on the eye chart) but affect the quality of what you see in real life. Higher order aberrations can actually be exacerbated by traditional LASIK surgery.

So what are higher order aberrations? As they relate to your vision, they are infinitesimal imperfections that create minute changes in the light rays that pass through your eye. These minute changes in the light rays affect the quality of your vision (even with glasses or contact lenses) although you are probably not even aware of the difference.
