Wavefront Diagnostic Technology

Wavefront technology was pioneered for astronomy and physics to aid in reducing aberrations or imperfections in the optical systems of telescopes and laser devices. In much the same way, wavefront-sensing devices are being used to produce an accurate picture of the optical imperfections found in the human eye. This technology is an improvement over past testing methods because it measures the entire optical system of the eye, instead of simply the front surface.

Wavefront technology measures your unique vision problems before surgery to create a customized laser vision correction procedure to make the exact correction your eyes need. This technology identifies vision problems that previously were undetectable and untreatable. It helps ensure the most accurate laser surgical treatment available.

How it works

Light travels in a procession of flat sheets known as wavefronts. These wavefronts enter the eye, pass through the entire optical system (the cornea, lens and retina) and are then reflected back. When the optical system has perfect refracting surfaces, these wavefronts exit the eye as regular, flat sheets. But when the cornea is irregular or the lens is imperfect, higher-order aberrations are created, and the wavefronts exit the eye as irregular, curved sheets.

Wavefront technology compares these curved sheets to a perfect wavefront. The system then determines what adjustments need to be made in order to produce a crisply focused image on the retina.

Durrie Vision was the first practice in the area to offer customized LASIK, utilizing wavefront diagnostic technology to treat your specific vision problems. We now combine this high-end diagnostic technology with blade-free precision to perform an advanced procedure called SBK.
