Short answer
ZEISS MEL 90 is an excimer laser — it reshapes corneal curvature in LASIK and PRK after flap creation or epithelial removal. It is the usual ZEISS pairing with VISUMAX femtosecond: one laser prepares, MEL 90 corrects.
What is it?
MEL 90 delivers argon-fluoride excimer pulses with fast eye tracking and support for wavefront-guided profiles from CRS-Master aberrometry.
How it works in your procedure
Wavefront or standard profiles load from ZEISS planning software. Ablation runs while you fixate; the tracker follows micro-saccades. After LASIK the flap is repositioned; after PRK a bandage lens is placed.
Why surgeons choose this platform
- ✓Wavefront-guided standard where indicated — not an optional marketing add-on.
- •ZEISS single-vendor workflow — diagnostics, femto, and excimer data compatibility.
- •Fast ablation times — typical treatment under a minute of laser time.
Who it suits — and who needs a different platform
- ✓Myopia, hyperopia, astigmatism within MEL 90 limits after Pentacam clearance.
- •Paired with VISUMAX for full ZEISS LASIK or SMILE (femto only) pathways.
How it compares to alternatives
Alternative excimers include AMARIS 1050RS and WaveLight EX500 — outcomes overlap when candidacy is correct.
Safety & what to expect
Excimer tissue removal is permanent — enhancements possible but limited by residual stromal bed. Understand femto vs excimer roles: femtosecond vs excimer.
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.
