New LASIK Technology

Custom LASIK or “Wavefront-driven LASIK” is a recent advancement in laser vision technology that allows the surgeon to personalize the procedure and to potentially improve the already excellent results obtained with traditional laser vision correction. This procedure uses wavefront LASIK technology, which provides new diagnostic information previously unattainable.


Wavefront LASIK technology was first developed in 1978 by Josef Bille, PhD, director of the Institute for Applied Physics at the University of Heidelberg, to measure wavefront distortions that occurred when light traveling through the atmosphere entered a telescopic lens.

This LASIK technology removed any visual distortion or aberrations from the atmosphere, allowing astrophysicists to more accurately view images of the stars and planets.

It is now possible to utilize this LASIK  technology to record detailed information about the visual characteristics of the eye. Unlike standard measuring devices such as corneal topography, which measure the front surface of the eye called the cornea, the wavefront scans the way the entire optical system processes light.

“Fingerprint” of the Eye

Wavefront analysis works by measuring the distortion or irregularities of the eye, known as higher-order aberrations. When a ray of light first enters the eye, it passes through the cornea to the lens and vitreous, ultimately reaching the retina.

As it bounces off the retina and returns back through the cornea, the wavefront analysis detects and documents these distortions, which are unique to each individual. Because each patient has a unique visual optical system, the wavefront data has been likened to a fingerprint.

Once the wavefront data has been documented for an individual patient, the next step is to use this information to utilize the excimer laser to correct the higher-order visual aberrations. The surgeon can then determine what adjustments must be made to the corneal surface to produce a clear, crisp image for the unique individual needs of each patient.

The use of wavefront LASIK technology to provide a more precise laser vision correction is known as "Custom LASIK" or "Wavefront-Driven LASIK." At Wake Forest Baptist Health Eye Center, we use the Allegretto Wavelight laser, which has been shown to reduce higher-order aberrations and improve night vision using “Wavefront Optimized” technology.
