Wavefront technology has been used for years as a tool by astronomers to adjust the optics of their telescopes. They use wavefront to help eliminate any aberrations, or irregularities, caused by the Earth’s atmosphere. Recently, this technology has been adapted for use by other fields, including ophthalmology.

Our ophthalmologists can use wavefront technology to diagnose the aberrations found in the eye so that they can be corrected during LASIK. This is done in two separate visits to Seeta Eye Centers. The first one evaluates and diagnoses the existing issues. During your second visit, this information is used to surgically reshape your cornea in order to restore clear vision. This procedure is known as wavefront-guided LASIK.

This page will provide a basic overview of wavefront-guided LASIK, but we'd be happy to answer any questions you may have about the procedure during your initial eye evaluation. Please call 845-454-1025  today to schedule your free consultation at one of our offices, conveniently serving Poughkeepsie and the entire Hudson Valley area.

High Order Aberrations

The basic eye examination evaluates low order aberrations (LOA). With LOA, our ophthalmolotists can tell if you have refractive vision problems such as nearsightedness, farsightedness, or astigmatism.

LOA can only be measured to a certain point. However, with wavefront diagnosis, measuring high order aberrations (HOA) can be done far beyond what LOA can see. This is because HOA are represented using mathematical equations. As a result, the readings are infinite and as close to perfect as possible.

No other system of eye measurement comes close to wavefront technology. It helps our ophthalmologists to effectively determine the necessity for LASIK, PRK, or the other variations of LASIK. Anyone considering laser vision correction surgery must have wavefront diagnosis. Wavefront technology can perform both LOA and HOA.


Wavefront diagnosis helps to create a detailed map of your eye. By looking at the eye in detail, our eye surgeons will be able to determine if any aberrations would be made worse by laser surgery.

During wavefront diagnosis, a specific pattern of light is directed at the eye. After passing through all parts of the eye, a measurement is taken. The difference between the pattern that entered the eye and the measurement that comes out is considered an aberration.

Using wavefront-guided LASIK enables our LASIK surgeons to deliver the most precise results possible during your procedure. This not only expands the amount of people who are considered candidates for LASIK, but it increases the likelihood that you'll achieve 20/20 vision or better during your procedure.
