Your Central Oregon wavefront LASIK Source
In a field whose technology is constantly changing and evolving, we strive to stay current by offering our patients treatment with the most advanced laser vision correction systems available. The technologies in use at our Bend, Oregon-area wavefront LASIK surgery center include:
- Iris Registration
- VISX Star S4 Excimer Laser with wavefront Technology
- WaveScan Diagnostics
- Orbtek Orbscan
- Hansatome Microkeratome
- Flap Aspiration
As the newest and most exciting development in the field of LASIK technology, iris registration introduces a new level of accuracy and quality for laser vision correction. We've implemented this technology, available only from VISX, to bring our patients in the Redmond and Bend, Oregon, areas a wavefront LASIK treatment with even higher quality results than ever before.
Somewhat like taking a fingerprint of the eye, the iris registration system detects and records unique points in the pattern of the iris. It then creates a map, which it uses to precisely align the laser vision correction treatment to the eye. This allows the system not only to apply the laser treatment with extreme precision, resulting in dramatically more accurate vision correction, but also to adjust the treatment for changes in the shape of the eye as the patient moves from an upright position to a horizontal position.
Not every patient who is a candidate for wavefront LASIK will automatically be a good candidate for iris registration. During your surgery, the doctor will be able to determine whether iris registration will work for you. If you are a candidate for iris registration, as most people are, it will be implemented during your procedure at no extra cost to you.
VISX Star S4 Excimer Laser with wavefront Technology
The VISX Star S4 Excimer Laser, used at our Bend, Oregon-area office for wavefront and other LASIK procedures, is widely acknowledged as the premier laser in refractive surgery. The makers of this system have spent years developing and perfecting their excimer lasers, and are recognized as leaders in the field. The VISX Star S4 features cutting edge technologies that have set new standards in customized, precise results and patient comfort and safety. These new technologies include:
Variable Spot Scanning (VSS)
With variable spot scanning technology, the size and shape of the laser beam can be easily changed. This allows a great deal of flexibility in designing personalized treatments that fit each patient's individual needs. Beam sizes range from .65mm to 6.5mm, and beam shapes can vary as well. This technology controls the amount of corneal tissue removed, which is an important safeguard to maintaining corneal stability.
Variable Repetition Rate (VRR)
Unlike other lasers, the Star S4 laser has a variable pulse repetition rate, allowing for a faster procedure. When used to treat smaller areas, the laser can safely pulse at a quicker rate than other systems, taking less time to remove the necessary amount of tissue. The shortened procedure times minimize corneal dehydration and maximize treatment results, as well as improve patient safety and comfort.
ActiveTrak 3-D Active Eye Tracking
Patients can now relax during treatment, as they no longer have to worry about keeping their eyes perfectly still. ActiveTrak 3-D Active Eye Tracking is a feature that allows the laser to track and follow any left and right or up and down eye movements that take place during the surgery. The laser will instantly realign to the correct location should eye movement occur.
Our office, serving the Redmond and Bend, Oregon, areas, offers wavefront LASIK because it provides highly accurate laser vision correction. Part of its accuracy is due to the WaveScan diagnostic system that is used to measure the refractive error and map the surface of the cornea. The WaveScan diagnostic system eliminates the need for guesswork by shining a harmless laser into the eye and measuring its exit pattern. These data are analyzed and used to produce a detailed map of the eye's imperfections. The digital information is then transformed into specific programming instructions which direct the laser's treatment path during surgery.
With WaveScan diagnostics, we are able to measure refractive error with 25 times the precision of traditional methods. We are also able to detect any minute imperfections in the surface of the cornea that may interfere with optimal vision. Using wavefront LASIK technology, we apply laser vision correction treatment that is customized to account for the exact refractive error as well as any imperfections in your eyes only, resulting in maximum visual potential. This level of accuracy far exceeds any other form of vision correction previously available.
Restore Vision Centers is committed to patient safety and satisfaction. Before our Bend, Oregon–area patients undergo wavefront LASIK or any other laser vision correction procedure, they must be screened to ensure that they are good candidates for the treatment. In addition to using WaveScan diagnostics, we evaluate eyes with the Orbtek Orbscan. This 3-D scanning device maps the front and back surfaces of the cornea, as well as the interior. In rare cases, slight imperfections may exist inside or at the rear of the cornea. These cannot be addressed with LASIK and will prevent a laser vision correction procedure from effectively improving vision. Orbtek Orbscan technology allows us to detect any such imperfections before the patient undergoes LASIK.
The microkeratome is an integral tool used in LASIK procedures. It creates the tiny flap on the surface of the cornea and allows the laser to access the underlying corneal tissue. At the Restore Vision Centers location near Bend, Oregon, we use the Hansatome microkeratome, which is a fully automated system that creates thinner, broader flaps than other flap-cutting devices. This allows for better treatment, shortens healing time, and reduces the chances for infection or complication. The Hansatome microkeratome is widely recognized as the safest and most effective instrument available for creating corneal flaps.
As technology advances, many older techniques become obsolete and fall out of practice. In most cases, this is a natural and beneficial process. However, we still practice flap aspiration at Restore Vision Centers near Bend, Oregon, as part of the wavefront LASIK procedure, because we believe it is proven to provide worthwhile benefits for our patients. After the laser treatment has been administered, we aspirate, or clean, the surfaces of both the cornea and the corneal flap before the flap is repositioned. This process speeds healing and reduces the risk of post-operative infection. Many offices no longer perform flap aspiration because it takes a little extra time, and because they believe it is unnecessary. However, we believe that ensuring patient safety and comfort is worth the few extra minutes to improve the service we provide.
