NASA recently approved the LASIK technology and procedure used at Optical Express for use on astronauts.
State-Of-The-Art Technology
When considering laser vision correction, technology is a fundamental question. Not all lasers are the same. Yesterday´s laser gives yesterday´s results. At Optical Express we use only the technologically advanced VISX S4IR™ laser. This laser currently treats over 60% of patients in the US, where most laser procedures in the world take place. It is proven to deliver SAFE, ACCURATE and PRECISE results. This is why athletes and celebrities like Tiger Woods and Cindy Crawford chose to be treated with this laser.
VISX lasers - what are they?
The VISX excimer laser used in refractive surgery is a gentle, cool beam laser that reshapes the cornea at the front of the eye. The VISX laser removes less tissue from the cornea per diopter of prescription than most of the lasers used by other providers. Each laser pulse removes 0.25 microns of tissue.
1 micron = 1 thousandth of a millimeter. This is the same as removing:
1/200 of a human hair, or;
1/39,000,000 of an inch;
in 4 billionths of a second.
To ensure the highest standards of quality vision, all Optical Express lasers are equipped with advanced eye tracking technology. The 3-D eye tracker works by guiding the beam while it moves over the cornea, ensuring that the laser treats only the section of the cornea that needs re-shaping. The 3-D eye tracker also ensures that even if your eye moves, the laser beam tracks the movement thus enabling a safe and precise treatment.
As laser vision correction continues to evolve, Optical Express constantly provides our teams with the best resources and latest technology to remain a global leader in the industry.
