The Advanced CustomVue™ Procedure
Takes LASIK to the Next Level
When Advanced Medical Optics (AMO) acquired VISX in 2005, it gained a legacy of history-making innovation that led VISX to introduce laser vision correction in 1996. At first, doctors and patients were understandably skeptical about using lasers on eyes. As time passed and favorable results increased, growing acceptance remained tempered by the narrow range of indications, lack of certainty that every patient treated would experience the same level of improvement, and a small but persistent percentage of patients who experienced side effects such as halos or blurry night vision.
VISX’s LASIK treatment gained FDA approval in 1999, reducing patient recovery times. Wavefront technology appeared in 2000 and transformed laser vision correction, similar perhaps to the way minimally invasive endoscopic (arthroscopic) devices changed knee and other surgeries. Wavefront technology allowed doctors to measure and create a remarkably precise digital map of the optical system showing lower and higher order aberrations.
The benefit of wavefront technology was realized when VISX refined it using proprietary Fourier algorithms and integrated it with their STAR™ Excimer laser technology. The new VISX Technology™ system both measured each eye’s unique imperfections and created a treatment plan that fed directly into the laser, delivering a completely customized treatment to each eye. The CustomVue™ wavefront-guided LASIK procedure was approved by the FDA in 2003, initially for treating mild myopia with or without astigmatism.
To appreciate the revolutionary change the CustomVue procedure brought to LASIK, imagine the difference a similar technology could make to your practice. Consider how different your practice might be if you could create a precise digital map of your patients’ corneal surfaces and feed that data into a machine that would custom create optically perfect glasses or contact lenses that accurately corrected lower and higher order optical aberration – in each eye. That’s essentially what VISX Technology did for LASIK when the company combined excimer laser and wavefront technologies.
The Next Generation:
The Advanced CustomVue Procedure
VISX Technology didn’t stop at the CustomVue procedure. Over the next few years, the company added new advances to its STAR S4™ laser including:
- Iris Registration (IR) – The first FDA approved, fully automated, non-contact method of alignment of the correct CustomVue treatment to the corneal site
- Variable Spot Scanning (VSS™) – Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times
- Variable Repetition Rate (VRR™) – VRR delivers treatment at varying repetition rates, optimizing treatment time
- ActiveTrak™ 3-D Active Eye Tracking – Captures all 3 dimensions of intra-operative eye movements – no dilation required
- ActiveTrak Automatic Centering – Locates, and then automatically sets the treatment center to the center of the pupil
The STAR S4 IR™ laser incorporates these advanced technologies into the Advanced CustomVue treatment, delivering the highest level of precision and accuracy ever achieved. Surgeons rate the Advanced CustomVue procedure as the most effective advanced laser treatment available today,* and it is FDA approved to treat the broadest range of indications; including hyperopia, all forms of astigmatism, and myopia up to 11 diopters of correction. Results of the clinical trials for all indications showed that one year later:
- More than 95 percent could pass a driving test without glasses or contact lenses
- Almost three quarters could see 20/20 or better without glasses or contact lenses
- The vast majority were satisfied or very satisfied with yheir night vision after treatment compared to night vision before treatment with glasses or contact lenses
For your patients who are considering LASIK, or who you feel could benefit from laser vision correction, ensure they choose the Advanced CustomVue procedure from AMO.
