Wavefront LASIK

Eye care specialists have traditionally used standard measurement techniques that identify and correct lower-order aberrations, such as nearsightedness, farsightedness, and astigmatism. However, no two
people share the same eye irregularities or have similar refractive needs. Vision is unique and as personal as fingerprints or DNA.

Wavefront technology allows eye surgeons to customize the LASIK procedure for each eye, providing the possibility of even better vision. The FDA approved the first system for general use in October 2002.
A laser beam is sent through the eye to the retina and is reflected back through the pupil, measuring the irregularities of the light wave (wavefront) as it emerges from the eye. This process produces a three dimensional map of the eye’s optical system.

Measuring the cornea’s imperfections or aberrations in this way allows the refractive surgeon to develop a personalized treatment plan for the patient’s unique vision needs. Correcting the patient’s specific imperfections can result in sharper vision, better contrast sensitivity, and reduces problems associated with higher-order aberrations after surgery, such as haloes and blurred images. Studies indicate that 90-94% of patients receiving wavefront LASIK achieved visual acuity of 20/20 or better. However, those with thin corneas, high degrees of aberrations, severe dry eyes, or conditions affecting the lens and vitreous fluid inside the eye may not be good candidates for wavefront LASIK.
