Eye Lens Surgery with Femtosecond Lasers
Why a Femtosecond Laser?
1 Fsec = 10-15sec = 1/ bilion of 1/milion of sec
In 1 fsec light travels only 0.3 micro-meter
Laser intensity: I =E/t . S
With much less energy dissipation for a femtosecond pulse, we can expect:
- Less thermal effect
- Less collateral damage
- More precise cutting
- Incision with good quality
