Excimer Laser

Accelerated Excimer Performance

Built on trusted WaveLight? excimer technology, the WaveLight? EX500 Excimer Laser is the next leap forward in fast, accurate refractive laser treatments.

Built for Speed and Superb Outcomes

The WaveLight? Refractive Suite is the fastest refractive surgery platform available in the US:

  • The WaveLight? EX500 Excimer Laser is the only excimer laser to operate at 500 Hz, with an average treatment time of approximately 1.4 seconds per diopter1.

  • The WaveLight? FS200 Femtosecond Laser is the fastest femtosecond laser available in the US, with a standard flap creation time of approximately 6 seconds1,2

  • The swivel bed is designed to optimize time between the flap creation and laser procedures.

Its innovative engineering helps reduce the potential for:

  • Stromal dehydration of the cornea

  • Flap shrinkage

  • Sensitivity to eye movements

  • Patient fixation fatigue

Customized LASIK for Every Eye

The built-in flexibility of the WaveLight? EX500 Excimer Laser allows surgeons to expand their refractive treatment capabilities:

  • Wavefront Optimized? and Wavefront-Guided treatments

  • Customized pupil-center centration options among different lighting conditions

  • Line of sight and corneal vertex centration


Precisely Focused on Accuracy

With a powerful 1050 Hz-type multi-dimensional eye tracker, synchronized at 500 Hz, the WaveLight? EX500 Excimer Laser offers safety and exceptional precision:

  • Movement tracking with just 2 milliseconds of latency*

  • Dynamic pupil tracking from 1.5 mm to 8.0 mm

*Treatment times are approximate

Optimized Shot Distribution

Utilizing proprietary PerfectPulse Technology?, the WaveLight? EX500 Excimer Laser maintains a high pulse frequency with a minimized thermal load1,4:

  • Only 1 pulse in 5 is allowed to overlap.

  • Optimizes temporal and spatial shot distribution5.

  • Additional pulses are sent to the periphery to compensate for energy loss.

  • Reduces the potential for nighttime glare6.

Designed With Efficiency in Mind

The WaveLight? EX500 Excimer Laser workstation has been ergonomically designed to provide enhanced information and usability throughout the refractive procedure:

  • Integrated heads-up display

  • Fiber slit projector with LED light source

  • Increased working distance of 25 cm

  • Standard, high-resolution video system

  • Built-in, non-contact, online pachymetry


The Cutting Edge of Laser Technology

Featuring enhanced beam path technologies, the WaveLight? EX500 Excimer Laser sets the standard for laser precision and durability:

  • Completely sealed beam path

  • Continuous nitrogen-flushed beam path

  • Onboard nitrogen generator

  • Long laser head life expectancy
