What is wavefront?

LASIK Vision Correction is a technique, using an Excimer Laser, to reshape the Cornea to help you see better without glasses. It can successfully correct Shortsightedness, Longsightedness and Astigmatism. It can now also correct Wavefront determined "higher order aberrations".

A perfect eyeball would focus every light beam that reaches it perfectly onto the retina. Unfortunately the eye is not perfect and as such some beams entering the eye, particularly the peripheral beams are sometimes focused either in front or behind the retina.

These out of focus beams create distortions known as higher order aberrations which can affect the quality of your vision, particularly at night or for those people with large pupils.

A Wavefront scan allows accurate measurement of each of these minute distortions known as higher order aberrations. The Wavefront scan itself is quick, painless and does not affect the eye or eyesight but as with the initial consultation and the LASIK treatment itself, needs to be performed without having worn contact lenses for a week.

Once the Wavefront scan has been completed, the results are uploaded into the Excimer Laser and the Wavefront treatment can be incorporated into the LASIK procedure. It is not an extra treatment, but in-built into the standard LASIK system. As a result, at the same time as treating Shortsightedness, Longsightedness or Astigmatism, your own individual higher order aberrations can be corrected in a customised treatment.

Is Wavefront treatment necessary for me?

If you have poor night vision, very large pupils or a moderate amount of Astigmatism, then Wavefront treatment may be appropriate.
Not everyone, however, is suitable for Wavefront treatment.
If your pupils are too small, your corneas too thin, or you have very few higher order aberrations, then Wavefront treatment may not be appropriate.

Our 2 hour free initial consultation allows us to determine whether a Wavefront scan is necessary as well as an opportunity to answer all your questions.

Once the Wavefront scan has been performed, we will be able to discuss the results with you and explain whether or not Wavefront treatment is appropriate for you.
