Custom Wavefront LASIK

Laser Refractive Surgery (LASIK, PRK,LASEK) has successfully corrected the vision of over 6 million people. An estimated 98% of conventional laser vision correction patients now see 20/20 to 20/40 without glasses. However, traditional LASIK can only address the visual distortions (aberrations) that account for about 85-90% of the quality of vision. Recently, refractive surgeons have learned that there are additional optical imperfections in the eye that affect vision and can account for such symptoms as glare, halos around lights, ghost images or poor quality of vision. These so-called higher-order aberrations can now be detected with an instrument called a Wavefront analyzer, also known as an aberrometer. As shown in clinical studies, this precise level of measurement and correction improves the potential to achieve 20/20 vision or better.*

wavefrontUntil recently surgeons measured the prescription for laser vision correction using exactly the same techniques that are used to prescribe eyeglasses and contact lenses. The laser treated identical prescriptions exactly the same for all eyes. Today, Gordon-Weiss-Schanzlin Vision Institute offers the newest technology to direct our lasers to provide a custom surgical procedure specifically designed for the individual eye. It not only corrects the error(s) from the eyeglass prescription, but also corrects the higher-order aberrations that can lead to the other 10% to 15% of visual distortions affecting your quality of vision. We call it All Laser High-Definition Vision and for many patients it can deliver even better results than current conventional treatment used by most eye surgeons.

Each of our lasers are capable of customized laser treatment. The first step is to generate a wavefront map by passing a narrow ray of invisible infrared light through the eye. The goal is to measure distortions in the eye’s entire optical system. The wavefront information is then downloaded to a floppy disk and transferred directly to the laser. At Gordon-Weiss-Schanzlin Vision Institute we have the unique ability to select the laser that has the potential to provide the best results for our patients.

About Custom Wavefront LASIK Surgery

At your consultation, you will undergo a wavefront and Oculus Pentacam corneal analysis in addition to other sophisticated diagnostic tests. Your surgeon will then base the decision regarding your treatment after a complete eye examination and analysis of your pupil diameter, corneal thickness, corneal curvature, corneal topography (shape) and wavefront analysis. You will meet with your surgeon at your consultation to discuss the recommendations and answer all your questions.

Customized LASIK, used in conjunction with our new ALLEGRETTO WaveLight® FS200 Femtosecond laser to create the flap, allows our LASIK surgeons maximum control and accuracy in customizing surgical parameters for each patient’s individual visual needs. The femtosecond laser was developed specifically to operate in conjunction with the Allegretto Wave® Eye-Q excimer laser to produce flaps in approximately 6 seconds and increase patient safety and comfort. This is the only system designed for complete integration between the excimer and femtosecond lasers.

Once you are prepared for treatment on the day of your LASIK procedure, the information obtained from your Wavefront analysis is integrated with our ALLEGRETTO Wave® Eye-Q excimer laser. The Eye-Q excimer laser is known as the fastest, most effective optical lasers available. The laser is able to follow the movements of the eye at 1000 times per second, giving your LASIK surgeon a very precise alignment of the eye’s position. Each treatment with the laser is customized to your prescription, with the aim of reshaping the cornea – as precisely and accurately as possible – to allow you to see more clearly without complete reliance on glasses or contact lenses. In some cases, this laser has allowed patients to achieve 20/20 vision or better.

The risks associated with All Laser Custom Vision treatment are the same as those with any form of laser vision correction. The ability to control higher-order aberrations and to reduce or eliminate any potential increase in these distortions makes customized laser vision correction a particularly desirable procedure. The improved software programs for All Laser Custom procedures have improved upon the excellent visual results that are currently obtained with conventional laser vision correction.

*Studies comparing results of wavefront LASIK with conventional LASIK found that 90 to 94 percent of patients receiving wavefront LASIK achieved visual acuity of 20/20 or better whereas up to 80 percent of those receiving conventional LASIK achieved 20/20 or better.
