Eye to Eye: Custom Wavefront LASIK vs. Traditional LASIK
By Andrew Holzman on October 13, 2015
By now, LASIK has become a household term. In fact, it has become so well known that some people believe that LASIK surgery is synonymous with laser eye surgery. This is not the case, of course; PRK and LASEK continue to provide exceptional alternatives to LASIK as far as laser eye surgery goes. Indeed, nowadays when a person mentions “LASIK,” an appropriate response might be, “Which type of LASIK?”
When the excimer laser was first approved by the U.S. Food and Drug Administration for use in LASIK surgery, this question would not have made sense. There was only one type of LASIK at that time. Now, however, this initial version of LASIK has been joined by several variations, most notably by one that uses wavefront technology to measure even the tiniest flaws in the shape of the cornea prior to surgery, resulting in a truly customized procedure. Custom wavefront LASIK has proven to be as significant a breakthrough in vision correction as conventional LASIK was when it was formally introduced to the U.S. market in the 1990s.
In discussing the issue of custom wavefront LASIK vs. traditional LASIK at his Washington DC eye care clinic, Dr. Andrew E. Holzman goes over the technological advantages of the former and why patients are more likely to achieve visual independence through this greater level of customization.

How does custom wavefront LASIK differ from traditional LASIK?
Both custom wavefront LASIK and traditional LASIK work according to the same basic principles:
- Visual errors are caused by imperfections in the shape of the cornea.
- By strategically removing tissues from the stromal layer of the cornea (the layer that lies directly underneath the top layer, the epithelium), these imperfections can be corrected, and the cornea can be returned to a more ideal shape.
- This more ideal shape will result in improved vision and a reduced need for glasses or contact lenses. In many cases, people no longer require glasses or contact lenses to see clearly at all.
The difference between custom wavefront LASIK and traditional LASIK lies in the type of visual errors that are corrected:
- Traditional LASIK: When traditional LASIK was conceived, it was possible to measure and correct only lower-order aberrations, or the most universal of the visual errors, namely myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These are the same errors that glasses and contact lenses have traditionally been able to address.
- Custom wavefront LASIK: With the advent of wavefront technology, it became possible to detect higher-order aberrations - tiny, unique imperfections in the shape of each cornea - that could not previously be identified or measured, let alone corrected. Now, wavefront maps of each individual eye can be created prior to LASIK surgery and used to guide the excimer laser during the reshaping of the cornea.
