The Femtosecond lens has replaced the mechanical blade. Blade surgery has been used to perform LASIK procedures for several years, but it poses more risks to patients. The surgeon can treat thin, curved, or flat corneas. Lasik surgery is a risky procedure because it involves cutting and stitches that require a lengthy healing time. Femtosecond laser offers the most effective possibilities of surgery, with a lower risk. Femtosecond laser exerts only very little pressure on the eye and its precision eliminates the possibility of cut-offs that are not even or properly formed in cornea tissue.
The advantages of having lasers operate only in femtosecond pulses is that that is a very short burst. This means that there is minimal damage around the site that is being treated and the burst of laser light can be focused on the exact spot it is required.
Femtosecond laser technology is a revolutionary tool used in various medical fields, including ophthalmology. It utilizes ultrafast laser pulses, lasting femtoseconds (one quadrillionth of a second), to perform precision and controlled surgical procedures. In refractive cataract surgery, femtosecond lasers offer high accuracy and customization. This technology enhances the surgeon's ability to achieve optimal visual outcomes.
If with less you intend "dealing with smallest dimensions" femtosecond lasers exist, emitting pulses whose duration is one billion part of a microsecond.
A femtosecond is one billionth of one millionth of a second.

I could write 1 femtosecond as "1 femtosecond" : not a zero in sight. or as 0.000001 nanoseconds (6 zeros) or .000001 nanoseconds (5 zeros) 1 fs = 10-15 seconds so there are 14 0s between the decimal point and the 1.
A femtosecond is 1000th of a picosecond.
