Wavefront LASIK Technology

WaveFront - ResizedMandel Vision® is proud to have been the first laser eye surgery center in New York to introduce one of the most revolutionary advancements to analyze your eyes. Wavefront technology can now create a fingerprint of your eye. Wavefront sensors measure thousands of light rays from your eye to detect changes that were never seen before. Dr. Mandel’s clinical research with the VISX® Wavescan Wavefront system has been presented at the International Society of Refractive Surgery. It is used as a diagnostic and therapeutic tool to enhance our abilities to measure your eyes with an accuracy that was previously unattainable.

The VISX® WaveScan Wavefront System is the first stand-alone commercialized wavefront system in the world, and is the first system to obtain FDA clearance in the United States. LASIK surgeon, Eric Mandel, M.D. has worked on two previous wavefront prototypes of this system and brings an unparalleled level of experience to New York ‘s first commercial VISX® WaveScan Wavefront System. As a VISX® Teaching Center of Excellence, Mandel Vision® remains at the forefront of the latest in laser related technology.

How does Wavefront Technology Work?

Light is projected onto the retina (analogous to the film of a camera). The light rays create a wavefront that measures all the subtleties of your eyes’ visual system. Sensors in the wavefront device measure the reflected light rays (wavefront). Hundreds of microscopic lenses measure your wavefront and compare it to an undistorted wavefront. The system converts these wavefront measurements into color and numerical representations of your optical system creating a unique visual profile.

A waveprint or unique fingerprint of the patient’s eye with unprecedented detail is obtained. The diagnostic wavefront study combined with topographic (contour) and pachymetric (corneal thickness) measurements combine to offer the surgeon an unprecedented ability to customize your treatment.

Variable Spot Scanning and Variable Repetition Rate

The VISX® Star S4 Laser System minimizes the amount of tissue that is ablated (removed).

Variable repetition rates allow for faster treatments that lead to improved results. This is because the cornea dehydrates with time and a faster laser minimizes dehydration, which translates into more accurate treatments.

For years, patients from all over the world have sought the expertise of Dr. Mandel for their laser eye surgery. Join others in seeing clearly again. Patients from New York, New Jersey and Connecticut have opted to have their laser eye surgery experience using the wavefront technology available at Mandel Vision® in Manhattan.

The VISX Star S4 system is the only laser in the world with the most advanced wavefront system, fourier analysis. All other laser systems use a mathematical modeling system called Zernike Polynomials. This was an excellent choice initially, however the introduction of fourier analysis is a much more accurate fingerprint of a patient’s eye.

What is Fourier Analysis?

Fourier Analysis is a new mathematical tool which improves the precision of wavefront treatments (ablations). An easy way to understand the improved analysis with fourier is to look at what happens during analysis and treatment.

The wavefront machine captures 240 microscopic spots on the eye, whereas the Zernicke Polynomials can only capture 40 spots. The advanced fourier analysis system captures all 240 spots and uses all of them to most accurately correct the patients prescription. Concurrent with this advancement in wavefront analysis, the state of the art VISX® Star S4 laser was also dramatically improved to deliver a much more precise treatment. Therefore, the VISX Star S4 system is the world’s only system to have variable spot size and variable repetition rates. This allows the laser to deliver the fastest, most accurate delivery system. Remember, a fast laser and surgeon improves results because corneal dehydration (loss of water) is minimized.
