|Custom Vue Wavefront Technology|
|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.
With custom LASIK, your eye's ability to focus light rays is measured, and a 3-D map 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.
Wavefront technology is groundbreaking because it has the potential to improve not only how much you can see, visual acuity measured by the standard 20/20 eye chart, but also how well you can see, in terms of contrast sensitivity and fine detail. This translates into a reduced risk of post-LASIK complications, such as glare, halos, and difficulty with night vision.
How much you see depends on vision defects known as lower-order aberrations associated with common refractive errors including myopia, hyperopia, and astigmatism, which traditional LASIK can treat.
How well you see can depend on presence of the type and numbers of visual distortions known as higher-order aberrations, which can include irregularities other than common refractive errors. These higher-order aberrations can create problems such as decreased contrast sensitivity or night vision, glare, shadows, and halos. However, higher-order aberrations do not always affect vision.
