WHAT IS WAVEFRONT ? IS WAVEFRONT ALWAYS BETTER ? Although wavefront is considered the gold standard treatment in laser eye surgery there may be some instances where you will get just as good results with the standard procedure. Everyone's eyes naturally have differing amounts of night vision aberrations which is why some people complain about problems driving at night and some people don't. During a laser eye surgery consultation your visual aberrations will be measured and if they are found to be minimal then you may not necessarily benefit from wavefront treatment. With the older generation of lasers, wavefront would still have been considered a better option as they tended to make night vision problems worse, regardless of what your pre-surgery aberrations were. However, with the latest generation of lasers they have been developed taking this acquired wavefront data into account, meaning the laser ablation profiles have been updated to reflect this. This means that the latest generation of lasers do not significantly increase night vision problems following surgery.
WHAT ARE THE MAIN ADVANTAGES OF WAVEFRONT? Better night vision/less glare: A wavescan Aberrometer is used to measure many different locations across the whole cornea, taking into account peripheral points which are important when the pupils enlarge in low light levels.Using this information, night vision problems are significantly reduced following surgery. Examples of night vision problems are glare, haloes and starbursts.
More Accurate: Wavefront is more accurate giving you the best possible visual outcome.There is a higher chance of achieving 20:20 vision when compared with standard laser eye surgery. Wavefront is especially recommended for people with high prescriptions and those with large pupils. Better quality of vision: Wavefront improves not only how much you can see (how low down the chart you can read at the opticians)but also how well you can see it. The quality of your vision.Wavefront does this by reducing your eyes higher order aberrations (these reduce the quality of your vision).Higher order aberrations are responsible for reduced night vision, doubling/ghosting around images, glare and haloes around lights and starbursts. If you eliminate these, the quality of your vision improves.Less chance of a laser enhancement: With Wavefront there is a lower chance of needing a laser enhancement(re-treatment).
