Advanced CustomVue Wavefront

Advanced CustomVue Wavefront Demo

Optical Express offer two types of laser procedure: Standard and Advanced CustomVue Wavefront.

While conventional LASIK and LASEK have been revolutionary in vision correction, Optical Express also offers the latest in laser vision correction technology; Advanced CustomVue Wavefront is a treatment that allows the surgeon to further customise the conventional procedure to your eyes.

Advanced CustomVue Wavefront Explained

Wavefront laser vision correction is an advanced form of excimer laser technology. Just like a fingerprint, each person’s vision is unique to them. Before the recent advances in laser technology, surgeons would carry out LASIK and LASEK using standard measurements to correct vision and achieve excellent results. Now the new Wavefront technology can measure and correct the unique imperfections of each individual’s vision and most often this provides them with the potential to experience better vision than is possible with glasses or contact lenses. This technology was originally developed for use in high powered telescopes to reduce distortions when viewing distant objects in space. Now, surgeons can identify, measure and correct imperfections in an individual’s eyes 25 times more precisely than with conventional methods used for glasses and contact lenses.

Higher Order Aberrations

Several types of visual imperfections, referred to as lower and higher order aberrations, exist within the eye and may affect your vision (the amount of these aberrations vary from person to person). Previously, only lower order aberrations (such as short sightedness, long sightedness and astigmatism) could be measured and treated.

Now Advanced CustomVue Wavefront LASIK may help to further customise your treatment of these higher order aberrations that in the past could not be adequately treated with glasses, contact lenses or conventional treatments. Higher order aberrations may also have a significant impact on vision and have been linked to glare and halos which cause your vision to appear less good at night than during the day. Your laser trained optometrist and surgeon will recommend the best procedure for you based on your personal aberrations - these are unique to each individual's eyes.

The Procedure

1. Wavescan Capture

A Wavescan capture of your visual system is produced which displays all of the higher order abberations present.

2. Data Transfer

This information is automatically transferred to the laser platform and used when your eye is being treated.

3. Precise Results

All lower and higher order abberations have been eliminated from your eye.

Safety and Accuracy

Safety and accuracy are taken to the highest level with CustomVue Wavefront technology using Iris Registration. Twenty four unique reference points in your eye are identified by the Wavescan, automatically transferred to the laser and matched to your eye. Any alterations in pupil size or eye position will be managed by the laser, ensuring optimum precision of treatment. LASIK and LASEK can be carried out using the Wavefront laser technology.

The Technology of Advanced CustomVue Wavefront

Together with Wavefront technology, our ActiveTrak 3-D eye tracker actively follows the tiniest movements of the eye in all three dimensions which keeps the laser centred to within 50 microns (about the width of a human hair) even if your eye moves during treatment.

Due to the high standard of vision required, all servicemen in the USA Navy who require Laser Vision Correction are treated only on the most advanced technology platform in laser vision correction - the VISX S4IR with Wavefront.

Advanced CustomVue Wavefront Results

The VISX S4IR excimer lasers have been used successfully to treat over 10 million eyes in the U.S. and over 20 million eyes globally. One year after having the new Wavefront procedure, patients in a clinical study showed that:-

Prior to surgery 80% of Optical Express patients could not read the large ‘E’ when viewed from 20 feet, without their glasses or contact lenses.

Following surgery 100% of study participants could see well enough to drive a car legally without glasses or contact lenses.*

Following surgery 98% of study participants achieved 20/20 (6/6) vision or better.*

70% of FDA study participants were 20/16 (6/5) vision or better.*

*Advanced medical optics FDA clinical study 2005

The benefits of Advanced CustomVue Wavefront customised laser treatment include:

• Wavescan measures and calculates the imperfections in vision 25 times more precisely than standard methods, potentially giving better vision after treatment than before treatment with glasses or contact lenses.

• 98% of patients achieving 20/20 vision or better than with standard treatment methods.

• Improved quality and consistency of vision in different light levels. In a clinical study, four times as many people were very satisfied with their night vision after the procedure compared to their night vision before with glasses or contact lenses.

• Iris registration provides you with improved accuracy and clinical outcomes.

Wavefront gives you the potential to see better than a standard procedure does.
