Wavefront Laser Eye Correction

Click here to watch an excellent live web seminar on wavefront laser correction

Many patients do not realize that the eye is an imperfect optical system. As light rays from distant objects pass through the individual optical components of the eye, they are subject to being distorted by the imperfections found in the cornea and the crystalline lens.

The distortions that are created are referred to as "aberrations." The vast majority--90% or more--of these aberrations create common refractive errors, such as nearsightedness, farsightedness and astigmatism, which can be treated by optical devices, like glasses and contact lenses, or by Laser Vision Correction, using the conventional methods of LASIK, PRK or LASEK. The remaining 10% of optical aberrations create images which are altered by chromatic aberration, spherical aberration, diffraction, curvature of field, coma, trefoils and quadrifoils--collectively known as "higher order aberrations." These higher order aberrations only occur in a visually significant manner in 10% to 15% of the general population. When they do occur, they are entirely unique to a particular patient--much like a fingerprint. For these patients, the use of a wavefront-guided laser technique to create a completely customized reshaping of the surface of the cornea may be the best treatment option.

To achieve a customized corneal shaping, it will require measuring the higher order optical aberrations using a wavefront analysis system called an aberrometer and then digitally interfacing it with a laser, using high speed computerized control to direct the delivery of a very tiny beam of laser energy across the cornea.
