VISX pioneered the development of excimer laser systems and remains the industry leader in quality and innovation. Their ActiveTrak” system not only provides the best in safety, accuracy and comfort, but it is the system that doctors have trusted in over 2 million procedures. Their rigorous Research and Development practices continually improve technology and processes, resulting in meaningful clinical applications - and better vision.
VISX laser systems have features that translate into several advantages for you:
-
VISX laser systems produce the smoothest surface on the cornea after the procedure. Smoother ablations, as they're known, promote faster healing and result in better vision.
-
VISX laser systems allow the doctor to track your eye movement in all three dimensions during the treatment, for greater control.
-
VISX laser systems achieve an optical zone that may result in reduced problems with night vision
-
VISX ActiveTrak™ laser systems produce seven variable sized beams, giving the doctor greater flexibility and allowing for a faster, smoother treatment with precise corneal shaping
-
VISX laser systems require a shorter procedure time, which enhances comfort and may reduce the risk of postoperative complications.
Once again, the Cincinnati Eye Institute Laser Center takes the lead in ophthalmology with the delivery of the most advanced eye tracking technology now available on the market - the VISX Star S4 ActiveTrak Excimer laser system. This newest generation laser system incorporates the latest active eye-tracking system in addition to many other advancements to help our surgeons deliver the best possible treatment. VISX's patented variable beam technology allows the fastest treatment time and provides the future platform for custom treatments. Designed to provide better laser vision correction, the ActiveTrak eye tracker is a new 3D eye-tracking technology. With ActiveTrak, the laser detects and compensates for small eye movements by guiding the laser beam to keep it centered precisely over the treatment area. It continuously repositions the laser beam throughout the procedure for greater accuracy and realigns itself between each laser pulse insuring pinpoint accuracy. The eye tracker adds a new level of precision, comfort, and safety. This new technology makes older eye trackers - which require dilation - virtually obsolete. Compared to other trackers, ActiveTrak requires no pupil dilation, which allows the surgeon to center the laser beam more accurately. Not having to be dilated eliminates the inconvenience and discomfort of dilation, and adds to patient confidence with the safety of the procedure. Because vision is not hindered by dilation, most patients are able to appreciate the improvement in their vision immediately after being treated.
The Orbscan measures both the front and back surfaces of the cornea with microscopic accuracy. It is an essential tool for maximizing the safety of laser vision correction. There are some irregular curvatures of the cornea that can lead to poor results in refractive surgery. If we find one of these irregular curvatures, we recommend that you do not have refractive surgery. A topographic analysis of the front and back of your cornea is a very important test to have before undergoing any refractive surgery. Very few providers offer this high level of safety and precision to their patients.
The WaveScan system creates a map of the eye, much like a fingerprint, which allows the surgeon to formulate a special treatment plan for each patient. Even though two patients may have the same prescription, their eyes are not the same. The WaveScan’s optics project light into the patient’s eyes, this visual pathway is then analyzed by thousands of tiny mirrors, thus creating a pattern of vision based on how the light was bent. This pattern of vision is your individual WavePrint, fingerprint of your vision. By having this fingerprint of your vision, the surgeon can better determine your candidacy for laser vision correction.
Originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space, the technology has now been applied to laser vision correction, offering a level of measurement that is 25 times more precise than the standard measurements used to determine your eyewear prescription. The Cincinnati Eye Institute was the first center in the country to have this clinically advanced WaveScan technology. Our LASIK specialists have been instrumental in working with the manufacturer for over two years, offering our patients an unprecedented level of expertise.
The WaveScan produces a visual representation, or map, of how your eye’s own optical system processes light. This map provides a precise and detailed analysis of your eye’s unique visual characteristics. Much like your own fingerprint, no two eyes are exactly alike. Your surgeon then uses this analysis to create an
individualized treatment plan to correct your eyesight for an optimal visual result. The Wave Scan’s digital information is then transferred to the VISX Star S4™ Excimer laser system, providing you with an increased level of precision and accuracy.
 We know the decision to have LASIK surgery is a big one, so we take great care to determine what’s best for you as our patient. That’s why we offer IntraLase as step one in your LASIK treatment.
With IntraLase, a beam of laser light is used to create your corneal flap, which is then lifted so the second step of LASIK—the reshaping of your cornea—can be performed. When your LASIK treatment is over, the flap is securely repositioned into place. This bladeless, computer-guided technology is 100 percent more accurate than most of the mechanical microkeratomes (hand-held device with a thin metal blade) that surgeons may also use to create a corneal flap.
Because of the superior accuracy of IntraLase, certain patients who were ineligible for LASIK may now be able to have treatment. Ask your doctor today if you are a candidate.
IntraLase Assurance and Comfort
IntraLase has been used successfully on hundreds of thousands of eyes and we trust this advanced technology to deliver exceptional results. Our commitment is to provide you with the ultimate in comfort, safety, and outstanding vision. LASIK with IntraLase can help you achieve all of this—while it delivers the added assurance of knowing you’re being treated with the most advanced technology there is.
How IntraLase works.
Unlike mechanical instruments, IntraLase technology is uniquely able to program the dimensions of your flap based on what’s best for your eye. Then the IntraLase laser creates your flap from below the surface of the cornea—without ever cutting it. How?
-
IntraLase uses ultrafast pulses of laser light to position microscopic bubbles at a precise depth determined by your doctor.
- The laser light passes harmlessly through your cornea. Then the laser creating rows of these bubbles just beneath your corneal surface as it moves back and forth across your eye in a uniform plane.
- Next, the IntraLase laser stacks bubbles around your corneal diameter to create the edges of your flap. These bubbles are stacked at an angle that is determined by your doctor and is individualized to the way your eye is shaped.
- The process takes only about 30 seconds from start to finish—it’s quiet and it’s comfortable.
- Your doctor then gently lifts the flap to allow for the second step of your LASIK treatment. When treatment is complete, the flap easily “locks” back into position and rapidly begins to heal.
LASIK performed with IntraLase is preferred by patients.
In a survey of clinical practices, the vision in the IntraLase-treated eye was preferred up to 3 to 1 by patients over the vision in the mechanical blade-treated eye (among those who stated a preference).
Another example of CEI’s investment in technology is the Keeler Procyon Dynamic Pupilometer, a high tech measurement tool for evaluating the size of the pupil in various lighting conditions. The Procyon is completely objective and uses computer controlled image analysis to measure pupil diameter. Previously, vision specialists had to rely on manual measurement, leaving room for human error. An accurate reading of pupil size can make a major difference in the outcome of LASIK surgery.
In addition, measurement in low light conditions or a dark room has direct bearing on the success of LASIK surgery. Patients with pupils that dilate larger than the area treated by the laser could potentially experience glare or a halo around objects at night, reducing their ability to see in the dark. With its illuminated display area, the Keeler Procyon can be used in a completely dark testing room, which reduces interference with ambient room light and improves the results of LASIK surgery.
