Custom LASIK surgery, also known as wavefront LASIK or wavefront-guided LASIK, uses 3-dimensional measurements of how your eye processes images to guide the laser in re-shaping the front part of the eye (cornea).
With a wavefront measurement system, some extremely precise, individualized vision correction outcomes may be achieved that would be impossible with traditional LASIK surgery, contact lenses or eyeglasses.
You should be qualified under FDA guidelines before custom wavefront LASIK is considered for your eye condition. Depending on the custom laser system used and other factors such as appropriate thickness of your cornea, you might be considered a candidate if you have mild to moderately high degrees of common vision defects such as myopia, hyperopia and astigmatism.
With custom LASIK, your eye’s ability to focus light rays is measured, and a 3-D map used in wavefront technology is created that demonstrates irregularities in the way your eye processes images. Information contained in the map guides the laser in customizing the treatment to reshape your eye’s corneal surface so that these irregularities can be corrected.
Standard prescriptions for glasses, contacts or traditional LASIK procedures can correct ordinary vision defects such as myopia, hyperopia, and astigmatism. But other irregularities associated with the eye’s optical system could not be addressed until the advent of wavefront and related technology used in custom LASIK.
