WaveScan® technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. This technology has now been applied to laser vision correction. The WaveScan WaveFront System's digital technology identifies and measures imperfections in your eye 25 times more precisely than standard methods.
The VISX® Fourier wavefront upgrade has the ability to capture wavefront information on larger pupil patients and utilizes this data for optical zone treatments out to 7 mm. Transition zones continue to be adjustable out to 9.5 mm. The WaveScan WaveFront System utilizes the patient's corneal K-values and wavefront measurement to create the optimal corneal shape for each individual, whether it be prolate, oblate, or spherical.
The WaveScan WaveFront System provides:
- Fourier-based wavefront algorithms
- Fourier delivers the highest resolution available of the wavefront error
- Uses more data points to derive the optimal shape
- Uses all data from any shape of pupil
- Accurately reconstructs all peripheral data
- Captures higher and lower order aberrations up to 7 mm diameter pupil
- WaveScan acuity maps: Chart the optical aberrations of the eye
- Difference maps: Track the changes of the eye for preop and postop comparisons
- Point Spread Function (PSF): Demonstrates how a patient would see a point source of light
Laser assisted in-situ keratomileusis (LASIK) can only be performed by a trained physician and is specified for reduction or elimination of myopia, hyperopia, and astigmatism as indicated within the product labeling. Laser refractive surgery is contraindicated for patients: a) with collagen vascular, autoimmune, or immunodeficiency diseases; b) who are pregnant or nursing women; c) with signs of keratoconus or abnormal corneal topography; d) who are taking one or both of the following medications: Isotretinoin (Accutane) and Amiodarone hydrochloride (Cordarone). Potential side effects to laser refractive surgery may include glare, dry eye, as well as other visual anomalies. LASIK requires the use of a microkeratome that cuts a flap on the surface of the cornea, potential side effects may include flap related complications. Consult with your eye care professional and Patient Information Booklet regarding the potential risks and benefits for laser refractive surgery, results may vary for each individual patient.
Restricted Device: U.S. Federal Law restricts this device to sale, distribution, and use by or on the order of a physician or other licensed eye care practitioner. U.S. Federal Law restricts the use of this device to practitioners who have been trained in its calibration and operation and who have experience in the surgical treatment and management of refractive errors.
