FEMTO-LASIK: All-Laser Precision for Safer Vision Correction
FEMTO-LASIK replaces the traditional mechanical blade with a laser for every step of the procedure, offering greater precision and predictability.
What Makes FEMTO-LASIK Different?
Traditional LASIK originally used a mechanical microkeratome (a precision blade) to cut the corneal flap. FEMTO-LASIK replaces this blade entirely with a femtosecond laser, which creates the flap using rapid pulses of laser light rather than a physical cutting edge — making it a fully “all-laser” procedure.
Advantages of the Femtosecond Laser
- Greater precision – the flap thickness and shape can be customized to the individual eye with micron-level accuracy.
- Improved safety – eliminates blade-related complications like an incomplete or irregular flap.
- More predictable healing – a more uniform flap edge tends to promote smoother, faster recovery.
- Suitable for slightly thinner corneas – precise control allows safer treatment in some cases traditional LASIK couldn't accommodate.

The Two-Step Process
- Femtosecond laser creates the thin corneal flap.
- Excimer laser reshapes the underlying corneal tissue to correct your prescription, exactly as in traditional LASIK.
Recovery Is Similar to Standard LASIK
Because the reshaping step is identical to conventional LASIK, recovery timelines are similar — most patients see significant improvement within 24 hours, with mild dryness or light sensitivity resolving over the following days to weeks.
Is FEMTO-LASIK Right for You?
Today, femtosecond flap creation is the standard of care at most advanced eye centers, having largely replaced blade-based microkeratomes. Your surgeon can confirm whether femtosecond LASIK, PRK, or SMILE best matches your corneal profile and lifestyle.
