Short answer
WaveLight EX500 is Alcon's high-speed excimer laser for LASIK and PRK — it performs the tissue-reshaping step after a femtosecond or microkeratome flap, or directly on the surface in PRK. Patients rarely 'choose' EX500; surgeons assign it when the Alcon treatment suite fits your profile.
What is it?
The EX500 fires excimer pulses with integrated multi-dimensional eye tracking (marketed up to 500 Hz tracking frequency) and PerfectPulse technology to maintain ablation consistency. It accepts conventional and custom profiles.
How it works in your procedure
Treatment mirrors other excimer workflows: flap lift or epithelial removal, then guided ablation while you fixate. Data from topography and aberrometry may import for customised LASIK when indicated.
Why surgeons choose this platform
- ✓High-speed ablation — short laser exposure time per eye.
- •Alcon ecosystem — pairs with Alcon femto and IOL platforms in cataract-refractive centres.
- •Established global install base — extensive clinical experience in LASIK and PRK.
- •Custom and standard profiles — surgeon selects based on aberrometry and prescription.
Who it suits — and who needs a different platform
- ✓LASIK and PRK candidates across myopia, hyperopia, and astigmatism within limits.
- •Post-refractive enhancements in selected cases after re-mapping.
- •SMILE seekers need VISUMAX — EX500 is excimer-only.
How it compares to alternatives
ZEISS centres often pair VISUMAX + MEL 90; Alcon centres pair femto + EX500. Clinical outcomes depend more on candidacy and surgeon experience than brand alone when platforms are modern.
Safety & what to expect
Same candidacy gates as all excimer surgery — sufficient corneal thickness, stable prescription, no progressive keratoconus. Compare ecosystems: VISUMAX vs WaveLight.
Procedures that use this platform
Technology serves the procedure — your surgeon assigns platform after scans, not before enquiry. These are the treatment pages where this device typically appears in your written plan.
