WAVELIGHT SYSTEM (BLADE-FREE LASIK)
Rosin Eyecare is proud to demonstrate our continued leadership role in laser vision correction by providing the latest technology to the Chicago Area.
WaveLight® was the first company to introduce high-speed laser vision correction in the United States. Now, the EX500 Laser takes the technology one step further with one of the fastest excimer laser system available today in the United States. Thanks to the incredible engineering of the laser, many people can have their vision corrected in as little as eight seconds, some even more quickly. At the same time, the EX500 delivers superior results with less risk of side effects. Predictable and optimal results are what our surgeons can deliver with the use of these two lasers.
So what makes the WaveLight EX500 Laser so special?
PerfectPulse Technology™ ensures safe and precise work on your eyes. Each ultra-thin laser pulse is used to sculpt the corneal surface of the eye with the utmost accuracy. The high-speed eye-tracker follows the eye’s fastest movements, checking the eye’s position 1000 times per second thereby ensuring accurate placement of each pulse on the cornea. In addition, an integrated cross-line projector provides the surgeon with an exact alignment of the eye’s position, making the EX500 one of the safest, most effective lasers currently available. PerfectPulse Technology™ represents a unique approach to laser vision correction. It accounts for much of the precision and predictability of the EX500 laser and offers advantages over all other available lasers in the United States. High-speed eye tracking charts the eye’s movement 1000 times per second, so that the laser will not correct your vision until eye position is exact and perfectly aligned. As a result, every laser pulse is completely controlled, allowing for the most accurate level of correction possible.
You can have peace of mind that the amount of energy in the laser has been calibrated to exactly the right level. After the beam has been created, it passes through three checkpoints on its way to your eye. At each of these points, the energy level is checked and adjusted if necessary, ensuring that the beam is perfectly attuned at its destination. The EX500 laser is essentially a precise, controlled beam of energy. The laser employs a proprietary overlapping method to ensure accurate laser placement, and is one of the ways that the EX500 is able to achieve a more natural corneal surface than many other lasers used for vision correction.
Due to the remarkable speed of both the eye and the EX500, the laser beam needs to be constantly and minutely adjusted to the position of the eye at any given time. One thousand times per second, the eye’s location is measured and the internal mirrors of the EX500 are automatically aligned. Just before the pulse is released, a second check is made to confirm that the eye has not moved. This happens 500 times every second, once for every laser pulse. If, at any time, the eye moves too quickly to be measured or moves out of range, the laser will pause and wait for the eye to move back into position.
The WaveLight EX500 is one of the fastest vision correction lasers for LASIK available in the United States. At 500 laser bursts per second, it takes less than two seconds of treatment to correct one diopter. Of course, spending less time under the laser means less stress for the patient and a potentially better outcome.
The WaveLight EX500 is capable of producing some of the largest available optical zones. This zone refers to the portion of the cornea that has been corrected by the laser. A larger optical zone is especially important for night vision and for patients with very large pupils. In the past, this has been one of the biggest limitations of conventional laser correction surgery. Wavefront-optimized technology built into the EX-500 laser addresses this limitation.
Wavefront-Optimized and Wavefront-Guided Technology
One of the most innovative features of the EX500 is that it is capable of BOTH Wavefront-optimized and Wavefront-guided treatments. Wavefront-optimized technology was released more recently and automatically compensates for the curvature of the cornea. In earlier laser correction systems, the “optical zone,” or area of correction, was centered on the front of the cornea; the result was a flattened circular area that ended with an abrupt edge, possibly causing unwanted side effects such as glare, and halos. The EX500 changes all that. The WaveLight EX500 sends extra pulses to the peripheral corneal area in order to compensate for the angle of the laser beam. In this manner, the natural aspherical shape of the cornea is preserved to a degree that older lasers simply could not achieve. This compensation, combined with the incredibly small, 1mm beam size of each pulse, produces a smooth, effective optical zone that can only improve results and minimize side effects. The EX500 also can be used to perform a Wavefront-guided correction utilizing aberration data (visual imperfections) in those individual that would benefit from such a correction. This technology is similar to what was originally introduced as CustomVue on the VISX laser in 2003.
Better Night Vision and Glare Control
At night or in dark conditions, the pupil becomes larger to permit the maximum amount of light to enter the eye. Laser vision correction needs to take this fact into account. If the laser treated optical zone is smaller than the size of the pupil at its largest, there is a possibility that night vision glare and halos around bright objects such as oncoming headlights will be more noticeable. The WaveLight EX500 is able to produce a larger optical zone, virtually eliminating glare and night vision problems associated with older generation lasers still used at most other practices in the region.
This amazing technology in conjunction with an experienced cornea trained LASIK surgeon is what creates predictable excellent results. The EX500 Laser is FDA approved for virtually all corrections including farsightedness, nearsightedness and large amounts of astigmatism.
Professional and clinically on target. My wife finally has received excellent care after being examined at Rosin. Highly recommend. Thank you.
I loved my visit here. I had a great doctor and I highly recommend her. She made the visit easy and smooth but was very detailed in her work. She was very open to my suggestions and gave me lots of options as far as lenses and gave me advice on how to improve my eyesight. The best visit with an Optometrist that I have ever had!
