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, 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. 


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.
