Wavefront Technology

Wavefront Technology is the latest technology available to treat vision correction.

Wavefront treatment is personalised by not only correcting your prescription but also aberrations or imperfections which occur naturally in your eyes. Each treatment is unique to your eyes. The result of the Wavefront treatment using the latest technology is a better quality of vision.

This type of treatment requires a sophisticated piece of equipment called an Aberrometer, which is capable of generating an accurate map of each eye and its aberrations (imperfections). Advance VisionCare has obtained the latest Wavefront technology: Zyoptix from Bausch and Lomb. The system used generates the Wavefront map, which is used diagnostically for initial consultation and post-operative analysis to ensure the best possible treatment is provided. Sophisticated software will then convert the wavefront map into a unique treatment prescription, which in turn will be electronically transferred to a computer controlling the laser itself.
The benefits of 'Wavefront' Treatment are :
Patients experience a higher quality of vision i.e. contrast (black on white) is more defined, than with standard LASIK.
Patients may experience a better vision in poor lighting, twilight, or for night driving.
The recovery time to good vision may be more rapid than with standard LASIK.
Wavefront technology removes less corneal tissue therefore patients with thinner corneas may be able to be treated than with standard LASIK therefore able to treat higher prescription safer and more accurately.

It is important to note that the aim of this treatment is not to improve detail of vision beyond that achieved with glasses (i.e. lines on the vision chart), but the overall quality of vision when compared to standard treatment.

Improved Quality of Vision

In low lighting conditions our pupils expand (or 'dilate'). Research shows that there are more 'aberrations' or optical imperfections at the outer edges (periphery) of the pupil. This results in a distortion of the light entering the eye. As a result, it is possible to be able to look at a round light source in the distance, but instead of seeing a perfectly round shape, you will see an irregular image. This distortion of light reduces the quality of our vision and explains one of the reasons why many patients experience difficulty with their vision when driving at night.

Zyoptix treatments have been designed to remove these optical imperfections, improving not just what we see, but the quality of how we see objects.
97% of patients reported a marked or extreme improvement in their quality of vision.

What results can you expect?

Significantly more Wavefront patients in this study experienced improved results with their vision when driving at night than patients that had received a standard Bausch & Lomb LASIK treatment.


Night Driving

More than 8 out of 10 Wavefront patients in this study reported same or better quality of vision in various common light conditions. 90.7% of patients reported the same or fewer difficulties with night driving.
Excellent Visual Acuity

Zyoptix produces a better quality of vision as well excellent visual acuity results. In this recent FDA approved trial, 91.3% of patients achieved 20/20 (6/6) vision without any correction 6 months after the treatment. 99.4% of patients achieved 20/40. 70.3% of patients achieved 20/16 vision without any glasses or spectacles, which is an improvement over the accepted standard of 20/20 vision.
