Lasik Vs. Wavefront Lasik - What's the Difference?

LASIK versus Wavefront
This terminology can get confusing. The only procedure I do any longer is Wavefront LASIK. What this means is that your eyes are individually mapped and "fingerprinted" which identifies your specific "nooks and crannies." Then this information is downloaded to the excimer laser and this specific pattern is treated. The results are better and there is less induced glare, halos, etc. "Standard" LASIK is an older term in which this mapping is not performed and...
New information on Customized LASIK
LASIK is the correction of "lower order aberrations" which is exactly what glasses correct. Wavefront or Custom LASIK was developed to treat small imperfections in the vision but in reality mostly was helpful in reducing the creation of new aberrations that were a side effect of the laser treatment. These corrections were popular at first but didnt always fix the lower order aberrations as well and thus not as popular as was originally hoped. Wavefront optimized is the current...
Customized Wavefront Lasik treatment
Wavefront technology is utilized to provide a mapping of one's unique characteristics of their eye, much like a fingerprint. This technology was adapted from astronomy 25 years ago to look at distant stars traveling the atmosphere. Now, we utilize this technology to provide information about the prescription as well as the unique small irregularities of one's eye. This technology allows us to measure the prescription of one's eyes 25 times more accurately! Utilizing this technology, we can...
Important Distinction Between Wavefront LASIK and Custom LASIK
This is a very important distinction for patients to understand. A Wavefront Custom procedure measure the refractive error (nearsightedness, astigmatism) as well as optical abberations or "wavefront errors". Every eye focuses light different across the pupil, and the Wavescan creates a unique treatment for each eye. This treatment is then downloaded into the laser (I prefer the Visx Customvue), the laser identifies the patient's eye by an iris fingerprint, and orients/aligns the treatment...
Wavefront LASIK optimizes and invidualizes vision correction
There are significant differences between wavefront-guided LASIK and conventional LASIK. First, there is a difference in the way the eye is measured. Wavefront-guided LASIK uses a wavefront scanner to measure the passage of light from the front surface of the eye to the back, creating a unique wavefront map for each eye. Second, the laser treatment is more precise, removing more of the aberrations that cause glare and halos. The data shows that...
Custom customvue wavefront hi-def LASIK vs LASEK
Everybody who qualifies and can afford it should get WaveFront or Custom or CustomVue or Hi-Def LASEK or LASIK, not standard. I know this as a patient, as I got non-wavefront LASIK a decade ago, before WaveFront came out, so I have some halos around lights at night. This problem is eliminated with WaveFront, as you can put a slightly higher Rx on the periphery of the cornea, which is necessary, as you actually need a higher Rx at the edge of your eye. CustomVue on the VISX laser I...
Traditional LASIK vs. Wavefront
Traditional LASIK corrects only your refractive errors (myopia, hyperopia or astigmatism) or what are also referred to as lower order optical aberrations. With wavefront LASIK we still correct lower order aberrations (myopia, hyperopia, astigmatism) but we also correct higher order aberrations which are unique to your eye and cornea. It is believed that by reducing both higher order and lower order aberrations the final visual outcome will be better.
Standard vs. Custom LASIK
With standard LASIK, you essentially receive what's in your prescription glasses or contacts lenses permanetly on your cornea to treat your nearsightedness, farsightedness, or astigmatism. With custom (Wavefront) LASIK, you receive that correction plus the correction for about a dozen other characteristics of your eyes that contribute to blurry vision (like distortion around headlights when you drive at night.) We charge the same at our practice for Custom and standard LASIK to make...
