VISX's

The cornerstone of VISX’s success has been based upon unparalleled Research and Development efforts in the field of Laser Vision Correction technology. Today these efforts are represented by the marriage of the STAR S4 Excimer Laser System and the WaveScan Wavefront System creating the CustomVue Procedure.

CustomVue

This procedure tailors a distinct correction for each individual – in fact each treatment is “designed” by the unique characteristics of the individuals’ eyes. WaveScan technology captures unique imperfections in each individual’s vision that could not have been measured before. This new level of measurement provides 25-times more precision than measurements using standard methods for glasses and contact lenses.

WaveScan technology produces a detailed map of the eye – much like a fingerprint, no two are alike and translates this information into a set of CustomVue treatment instructions for the laser. WaveScan transfers these digital treatment instructions to the laser, providing a new level of precision and accuracy.

Clinical Trials

VISX's FDA clinical study results were remarkable. Among other things:

At one year after the VISX CustomVue procedure:

• 100% of the clinical study participants could pass a driving test without glasses or contacts
• 98% of the clinical study participants could see 20/20 or better without glasses or contacts
• 70% of the clinical study participants could see 20/16 or better without glasses or contacts
• Four times as many clinical study participants were very satisfied with their night vision after the VISX CustomVue procedure, compared to their night vision before with glasses or contacts.

IntraLase

Is the first blade-free laser technology for performing the first step of the LASIK procedure: creating the corneal flap.

Prior to IntraLase, this first step was done manually using a hand-held device with an oscillating metal razor blade, called a microkeratome.

IntraLase delivers micron-level accuracy more than 100 times greater than a microkeratome

Benefits of IntraLase in LASIK

Pulsing at a speed of one-quadrillionth of a second, the ultra fast IntraLase FS Femtosecond laser brings micron-level precision and computer-controlled accuracy to corneal flap creation.

Clinical studies confirm that patients see better following LASIK with IntraLase than with the hand held microkeratome blade:

More patients achieved 20/20 or better vision with IntraLase-initiated LASIK.

IntraLase patients required fewer enhancement procedures following LASIK.
