Custom LASIK

 

Custom LASIK is a relatively new advance in refractive surgery. For particular cases, it has become so indispensible that Dr Khalil will decline the "classic" teatment in those cases.  Patients who receive "custom" LASIK, which also goes by various other proprietary names, such as CustomVue, receive a rewarding result. Custom LASIK surgery represents the next step in improving the outcome of laser vision correction beyond the excellent results already attainable by conventional means, espicially so, or some particular cases, like high astigmatism or irregular corneas. This is possible because every eye and its associated refractive errors are unique, much like one's fingerprint, and recent advancements in technology now allow us not only to measure these unique refractive imperfections, but also to accurately and predictably eliminate them.

The Goal of Custom LASlK: Quantity VS Quality of Vision

The WaveScan system to measure hidden aberrations

Modern Laser vision correction has been able to well correct nearsightedness, farsightedness and astigmatism. This is usually enough with 80% of people. In some people, there are other imperfections which can cause the vision to be impaired even if you are seeing 20/20.

Unless these imperfections are corrected, your vision may not be perfect even though you may be able to see the 20/20 line on the eye chart. They can cause difficulty particularly at night time and under poor lighting conditions. They can also cause glare, halos and other visual distortions.

How does it work

Image Name

At the heart of "custom" LASIK procedures is the aberrometer, such as the VISX WaveScan™ wavefront measurement system. By adopting technology originally developed for high-powered telescopes, wavefront measurements identify and quantify imperfections in an individual's eye 25 times more precisely than the standard methods used for eyeglasses and contact lenses.

Ideally in a perfect eye, all light would come to an exact point of focus on the back of the eye at the retina and bounce straight back out in a perfectly flat plane. In reality, all eyes have some degree of simple and complex imperfections.

Wavefront measures light that is reflected from the back of your eye out onto a wavefront analyzer. This Wavescan system separates the broad light into individual points of light that can be measured on a microscopic level. Mathematical formulas account for the "errors" at the corneal plane for each point. The result is a generated map or "fingerprint" of that individual eye's optical system. This data guides the laser to reshape the cornea for a truly customized treatment.

After careful review by Dr. Khalil, this information is then digitally transferred to the excimer laser for the treatment, providing a new level of precision and accuracy. It takes a few seconds longer for a "custom" LASIK procedure to be performed than it does for a conventional procedure. All aspects of the surgery are identical but the corneal reshapement is based upon the patient's unique wavefront data rather than on a non-customized or conventional measurement.
