Wave-Laser Improves Eye Surgery Results
Published: July 30, 2005
In LASIK, doctors gently fold back a thin protective flap of cornea protective tissue. The laser then has access to re-shape the cornea, and the flap is re-placed.
Dr. Keith Walter, an ophthalmologist at Wake Forest University Baptist Medical Center says, “The traditional LASIK procedure would give people 20/20 vision, but sometimes they would complain in low lighting conditions, they would see a little bit of fuzziness or at night they would see starbursts or halos.”
About a year ago, the FDA approved a new wave light laser. It’s faster than older lasers, with the average procedure lasting less than 10 seconds.
“It takes their cornea and maps it out in three dimensions and does a customized oblation on the surface of the cornea and it does extra pulses on the outside edges of the cornea, so that those areas are treated properly.”
This wave light laser also has a new safety measure built in.
“This laser has a pupil tracker which tracks at 200 times a second, which is the fastest tracking laser out there. What that means is if the patient moves their eye any slight amount, it will follow exactly where their pupil is and still correctly treat their prescription. if they move a little too much it will pause and then resume once they’re back realigned.”
Side effects from surgery include dry eyes which tend to improve within a few weeks.
