Custom lasik is also called as wavefront eye surgery.  Wavefront eye surgery makes use of 3-dimensional measurement of how an eye does the image processing and using this information, the laser is guided for re-shaping of the front portion of the eye. With this measurement system, an extremely precise and customized vision correction procedure can be done. These results would not be possible with traditional lasik eye surgery or contact lenses and eyeglasses.

To undergo a wavefront eye surgery, a potential patient has to qualify for certain guidelines prior to the custom wavefront procedure. Depending on which custom laser system is used and a few other factors like thickness of cornea, one can be considered as a candidate only if one has mild or moderately high levels of vision defects like myopia, hyperopia and astigmatism. In custom lasik, the ability of the eye to focus the light rays will be measured, after which a 3-D map is created to study irregularities about the eye’s processing of images. Information obtained from this map will guide the laser to customize the treatment of reshaping the cornea’s surface to correct these irregularities.

While prescriptions contacts, glasses or conventional LASIK procedures are able to fix ordinary defects like hyperopia, myopia, and astigmatism, other problems with your optical system can only be addressed with one vision correction procedure and that is the wavefront eye surgery procedure.

There are many advantages of Wavefront-Guided Custom lasik. Wavefront technology is sensational because in addition to the potential for improving the amount a person can see, improvement is also seen with regard to contrast sensitivity as well as fine detail. The advantages also include a greatly reduced risks of LASIK complications, like glares, halo and also difficulty with vision at night.

How much someone can see will depend on defects called the low-order aberrations which are associated in refractive errors like hyperopia, myopia, and astigmatism that LASIK can easily fix. How well someone sees depends on the presence of number and types of various visual distortions called as high-order aberrations that are all the optical defects present apart from the common optical errors. Higher-order aberrations can create problems of reduced contrast sensitivity as well as night vision, glares, shadows or halos. These high-order aberrations need not affect night vision. As opposed to traditional LASIK, customised LASIK can treat both low and high-order aberrations.

The custom LASIK’s advantages lie in the quality of the patient’s vision. There is a far higher  chance of getting 20/20 sight. There is a fair chance of obtaining greater than the 20/20 sight. There is very little chance of reduced corrected vision. There is a slim chance of reduced quality of vision and contrast sensitivity. Night-vision problems or glare do not result too often.

Not all surgeons concur that wavefront-guided laser treatment can treat more complicated aberrations. Studies show that wavefront as well as conventional LASIK, at times cause these complications due to changes made to the original shape of one’s eye surface.

Wavefront-guided LASIK has lower chances of inducing aberrations when compared to conventional LASIK
