Wavefront Technology

Wavefront-guided LASIK, Epi-LASIK and PRK are precise, customized form of refractive surgery that can correct vision problems beyond nearsightedness (myopia), farsightedness (hyperopia), and astigmatism as well as higher order aberrations. Wavefront guided treatments offer superior results compared to standard laser correction.

Established Technology Applied in a New Way

Wavefront is an established technology that has only recently been applied to human vision. Wavefront has been used for years by astronomers who need to adjust the optics of their telescopes. A reflecting mirror within the telescope that can be deformed is adjusted using wavefront data to eliminate aberrations induced by the Earth's atmosphere. With wavefront custom Epi-Lasik, PRK, LASIK, and LASEK, the excimer laser uses wavefront information to change the shape of the cornea by ablating tissue.

Wavefront is actually used in two separate steps before and during surgery. First, the wavefront aberrometer is used to measure existing aberrations. The second time wavefront is used is using what is to create a unique wavefront-guided laser ablation profile for LASIK, PRK, LASEK, or Epi-LASIK. This treatment is customized to each individual cornea.

With wavefront-guided mapping, light is sent into your eye and measured it has passed through the visual system.

A 3-D map is created that shows all of the distortions of light that occur in your eye, pinpointing aberrations. It is accurate up to the hundredths of a diopter, where previous methods were only accurate to ¼ diopter. This map is used to guide the laser during your surgery giving you a precise, customized procedure.

High order aberrations

Higher order aberrations are not measured by eye chart tests. Even if you have 20/20 vision, they can cause visual problems including:

  • Double vision
  • Poor night vision
  • Decreased contrast
  • Shadows
  • Halos
  • Glare

Advantages of Wavefront

Traditional refractive procedures can make higher order aberrations worse than they already are.

The precision of Wavefront prevents the creation of higher order aberrations and/or worsening of those that you may already have. With Wavefront-guided LASIK, Epi-LASIK and PRK you are:

  • Less likely to lose best-corrected vision
  • Less likely to lose vision quality
  • More likely to achieve 20/20 vision or better

Is Wavefront-guided Epi-LASIK or PRK for me?

Wavefront-guided refractive surgery may be the best option if you have higher order aberrations. Most people can benefit from the precision of this technique; however, it is not appropriate for everyone. Dr. Anderson Penno will conduct a thorough examination of your eyes during your Epi-LASIK/PRK evaluation to determine if Wavefront-guided Epi-LASIK or PRK is the right solution for you. If not, she will recommend your best option.
