There have been significant strides made in laser technology over the last five years, but finding a surgeon who has the experience and expertise to use that laser is critical to successful treatment. Some laser brands are Alcon, Bausch and Lomb, Nidek, Schwind, VISX, Wavelight, and Zeiss.

A laser beam will be a certain size and a certain shape. The point where the laser touches the eye is called a spot. The smaller the spot, the more focused it is, creating a higher intensity beam that moves around the eye at a faster rate. This means the laser only removes the material it needs to, providing a more precise treatment.

Your eye will move during surgery. Eye-tracking technology ensures your safety when this happens. Compensating for eye movement is a key factor in ensuring that the laser will be delivered to exactly the right place. There are different methods (video infra-red, 3D, LADAR), all of which involve detecting the position of your eye. There is a small time lag between the laser noticing that your eye has moved and compensating for that movement. All trackers, to date, provide approximately the same level of delay time – most operate with a delay of less than ten milliseconds (one hundredth of a second).
