LASIK and PRK have come a long way since first approved by the FDA more than 20 years ago. They have become the procedures of choice for most patients. Other options have also proven to be safe and effective such as the implantable contact lens (ICL, www.staar.com) and refractive lens exchange. Both LASIK and PRK involve using an excimer laser to reshape the cornea to achieve the desired vision after surgery. Here are the main lasers used in the US today. Boston Vision carries both technologies. Most patients will do as well on both lasers. On occasion, some patients are better candidates for one versus another. 

ALCON WAVELIGHT® EX500 EXCIMER LASER

What is the Alcon Wavelight® EX500 Excimer Laser?

One of the newest advancements in LASIK technology is the Wavelight® EX500 Excimer Laser from Alcon. This is a state-of-the-art laser that helps to make the LASIK surgery more effective. The laser’s ablation speed operates at 500Hz. This means that it checks the position of the eye 500 times a second, making this system the most accurate and efficient device on the market for eye surgery. It also includes an innovative swivel bed that decreases time for flap creation and laser procedures. 

What Are the Advantages of this Device?

At Boston Vision, we use the most advanced technology to help give our patients the best, most effective care. The Wavelight EX500 Excimer Laser offers many benefits. Innovates engineering and technology helps to reduce the potential for:

  • Flap shrinkage
  • Stromal dehydration of the cornea
  • Sensitivity to eye movements
  • Patient fixation fatigue

VISX S4 Laser and WaveScan

The VISX S4 Laser and WaveScan is an innovate device that helps with LASIK procedures. A WaveScan is a computerized device that is used to create a “fingerprint” of the patient’s vision prior to surgery. Your WaveScan is unique to you. This way the device captures your refraction and uploads your diagnostic data to the computer that operates the laser during surgery. This device was approved for use by the FDA in 1995. This improvement helps to expand the treatment ablation zone, this helps to minimize night aberrations in people who have large pupils. This laser uses sub-micron accuracy that can reshape the cornea, allowing the focus of light to fall on the retina. 

CustomVue and Iris Registration Technology

The CustomVue procedure is the combination of the STAR S4 Excimer Laser System and the WaveScan Wavefront System. The CustomVue procedure tailor’s correction for each individual patient. Each treatment is designed by the unique characteristics of the patient’s eyes. The WaveScan device helps to capture unique features of a patient’s vision that couldn’t be measured before. This helps to provide 25 times more precision than stand methods of measurements. The WaveScan creates a detailed map of the eye and sends this information to the computer for the CustomVue treatment.
