Wavefront LASIK – Seattle and Tacoma, Western Washington

In a field such as laser vision correction, technology moves quickly. We believe it is important to stay on top of new developments in equipment and techniques in order to provide high-quality care to our patients. At our office in western Washington, we bring our Seattle and Tacoma-area patients wavefront LASIK and other advanced technologies to help them achieve optimal vision correction.

Iris Registration

The newest breakthrough in wavefront LASIK technology, iris registration makes it possible to align the laser treatment better than ever before. By using technology that is similar to that found in eye-scanning security systems, the equipment takes a detailed "fingerprint" of the iris; it records and maps unique patterns and characteristics, which it later uses to precisely align the treatment to the cornea. This technology, available only from VISX, is more accurate than previous methods.

While other systems are able to adjust for movement of the eyes if they shift up and down or side to side during surgery, no system has previously been able to accommodate for the slight change in eye shape that occurs when a patient moves from a sitting position to a reclining position. Iris registration detects this shift, as well as any linear or rotational movement of the eyes, and correctly aligns the treatment. This results in the most accurate laser vision correction ever.

While iris registration works for most people, not all of our Seattle area patients will be candidates. Candidacy will be determined during the wavefront LASIK surgery, and if iris registration is appropriate, it will be performed at no extra cost to the patient.

VISX Star S4 Excimer Laser with wavefront Technology

High-quality treatment requires high-quality equipment. Our office in the Seattle and Tacoma area provides wavefront LASIK using the VISX Star S4 excimer laser because it is the most advanced and reliable vision-correction laser available. By incorporating several valuable technologies into one well-made, comprehensive system, VISX has produced the premier excimer laser. Some of the notable features of this system include:

Variable Spot Scanning (VSS)

Because each eye is unique and every refractive error is distinctive, it is difficult to reach the optimal vision correction for each person by always using the same size laser beam. The VISX Star S4 has a variable spot scanning function that allows the shape and size of the laser beam to be adjusted according to the treatment. With a range between .65mm and 6.5mm, this equipment is able to remove only the necessary amount of corneal tissue, improving both the safety and quality of the LASIK procedure.

Variable Repetition Rate (VRR)

Unlike other excimer lasers, which use a constant pulse rate, the VISX Star S4 is capable of increasing or decreasing the pulse speed, depending on the size of the area being treated. Smaller sections can be treated with more rapid pulses, removing more tissue in a shorter period and reducing the overall procedure time. Faster procedures result in more comfortable patients and a lower chance of complication.

ActiveTrak 3-D Active Eye Tracking

In order to be sure the laser is applied to the correct area of the cornea, the ActiveTrak 3-D Active Eye Tracking system tracks any movement made by the eye during the surgery. Since keeping your eyes perfectly still can be difficult, eye tracking makes the procedure much more comfortable. ActiveTrak 3-D Active Eye Tracking allows patients to relax, without fear of negatively affecting their LASIK results if their eyes move.

WaveScan Diagnostics

At our Seattle and Tacoma-area practice, we offer wavefront LASIK with WaveScan Diagnostics. This system is used to create a detailed map of the corneal surface prior to surgery. Traditional methods of vision correction use a one-size-fits-all approach, attempting to bring a patient's visual acuity into an acceptable range with the use of a standardized set of tools. However, since each eye is unique and each refractive error is the result of a distinctive set of irregularities, the only truly effective method of vision correction is one that is customized for each patient.

The WaveScan system detects minute imperfections and subtle variations in the surface and shape of the cornea that may affect the outcome of LASIK treatment. This equipment is also able to measure the refractive error 25 times more accurately than traditional methods can, while taking into account the unique characteristics of the individual eye.

Once the data are collected, the WaveScan system uses them to create a precise list of instructions for the excimer laser. This information is processed and transferred automatically. Following the detailed instructions created from the WaveScan diagnostic information, the VISX Star S4 applies a customized, highly specific treatment that is designed to maximize the vision correction potential of the patient. Our customized wavefront LASIK treatments result in better patient outcomes and fewer cases requiring enhancement procedures.

Orbtek Orbscan

While the WaveScan diagnostic system addresses imperfections on the surface of the cornea, we use the Orbtek Orbscan to reveal what is beneath the cornea's surface. In some cases, an irregularity may exist in the interior or rear portion of the cornea that affects visual acuity. Such internal abnormalities cannot be addressed with LASIK surgery and will usually prevent a LASIK procedure from correcting vision effectively. Orbtek Orbscan makes a detailed topographical map that can detect and show very subtle imperfections not only at the front of the cornea, but throughout. We use this technology during the screening process to be sure that laser vision correction will be effective before the patient undergoes the LASIK vision correction procedure.

Hansatome Microkeratome

Except for the excimer laser, the microkeratome, which is used to create the corneal flap, is the most important piece of LASIK equipment for helping to ensure optimal vision correction results. In our offices, we use the Hansatome microkeratome because of its proven reliability and extreme accuracy. This fully automated system is able to create thinner, wider corneal flaps than other equipment, allowing for a larger treatable area and less risk to the corneal structure. The corneal flaps created with the Hansatome microkeratome tend to heal faster and have lower risk of complication than those created with other microkeratomes.

Flap Aspiration

At Restore Vision Centers, we use some of the most technologically advanced tools and methods currently available in order to help our patients achieve the best results possible. We also strive to help our patients achieve optimal results by performing procedures that are neither new nor advanced. Flap aspiration is the simple act of cleaning the corneal surfaces before replacing the corneal flap. This step, which has been discarded by many practices as an unnecessary waste of time, only takes a couple of extra minutes and reduces the chances of infection or complication. We believe performing flap aspiration is worth the time because your eyes deserve the best care possible.
