A woman smilingGW Eye Associates offers some of the finest vision correction advice in the greater San Diego area. Patients who come meet with our eye care specialists can expect to receive close attention and exceptional care, including advice on selecting corrective lenses and which laser eye surgery procedure might be best for an individual's needs.

With regard to laser eye surgery, there have been significant improvements made in terms of safety and results thanks to wavefront technology. Let's take a moment to consider wavefront scanning right now.

What is wavefront technology?

Wavefront technology refers to an advanced form of digital scanning. The wavefront technology allows LASIK surgeons to create a highly accurate three-dimensional digital map of a patient's cornea, the clear, central outer surface of the eye. Using this precise scan of the corneal surface, minute imperfections in cornea shape can be identified and treated using a LASIK laser.

It is wavefront technology that makes custom LASIK surgery possible.

Isn't all LASIK customized to patients?

Yes, this is true, but wavefront technology takes this one step further. Previous LASIK procedures could address major issues with corneal shape with any regularity, while major issues with the cornea could not be treated easily. With wavefront mapping, greater customization is possible.

Added Accuracy Through Wavefront Mapping

Wavefront mapping allows refractive surgeons to identify even very small imperfections in the corneal shape and contour. This means treating lower order aberrations as well as higher order aberrations. By comparison, the LASIK of the past was only able to treat lower order aberrations reliably.

Excellent Treatment for Lower Order Aberrations

Lower order aberrations are better known by the following terms:

  • Myopia (Nearsightedness)
  • Hyperopia (Farsightedness)
  • Astigmatism

Wavefront custom LASIK is able to treat these lower order aberrations without difficulties.

Pinpoint Accuracy in Addressing Higher Order Aberrations

Higher order aberrations are the kinds of corneal imperfections that traditional LASIK often missed. Examples of vision problems caused by higher order aberrations include:

  • Glare
  • Halos
  • Poor night vision
  • Blurry images
  • Ghost images

The pinpoint accuracy of the wavefront mapping technology means that minute corneal issues can be revised and vision enhanced in the process. Because these minute corneal imperfections are treated, overall vision quality is far better in patients who undergo contemporary custom LASIK.

Computer-Guided Surgery Eliminates Human Error

In order to achieve these highly accurate results, the wavefront digital map is used to guide the surgical laser during the actual LASIK procedure. This eliminates the possibility of human error during the LASIK surgery, making the process even safer than it was in the past.

The Finest LASIK Surgery Results Possible

With added accuracy and greater safety that yields exceptional results, wavefront technology ultimately means the finest LASIK surgery available today. Custom LASIK surgery can make a positive impact on a person's life, and LASIK surgeons are excited to offer these advanced tools to help patients see the world around them better.
