It’s not often that a new excimer laser gets approved for laser vision correction, so when it happens, surgeons take notice. Recently, refractive surgeons were given a new excimer option with the Food and Drug Administration approval of the Alcon/WaveLight EX500 laser, which brings some new features and increased speed to the table. Here’s a look at the new laser and how it might fit into a refractive practice.

Treatment Speed

One of the key features of the device is its ablation speed, running at 500 Hz, vs. the speed of the previous model, the Allegretto Wave IQ 400 Hz. “Granted, it’s incrementally faster,” says Greensboro, N.C., surgeon Karl Stonecipher. “However, it matters. With a speed of 400 Hz, the laser ablated at a rate of two seconds per diopter. With 500 Hz, though, it’s speed is 1.4 seconds per diopter.” Dr. Stonecipher says it’s been his experience that up to about -7 D, the o...
