A femtosecond is one quadrillionth of a second.  In other words, there are 1,000,000,000,000 femtoseconds in every second. There are more femtoseconds in a second than there are years that the universe has existed.    A femtosecond laser is a laser which emits optical pulses with duration well below 1 ps (ultrashort pulses).  This puts the femtosecond laser in a category of ultra fast lasers or ultra short pulse lasers.    The role of femtosecond laser in cataract surgery is to assist or replace several aspects of manual cataract surgery.  These include the creation of the initial surgical incision in the cornea, the creation of the capsulotomy and the initial breaking up of the lens.  The laser may also produce incisions within the peripheral cornea to aid in the correction of astigmatism.   One of the key categories of this technology when it was first released in lasers for cataract surgeries was advanced technology lenses,  but using a femtosecond laser during cataract surgery will let you treat astigmatism as well. This new technology can also benefit patients with pseudoexfoliation, dense lenses and shallow chambers.    Patients who want the best implant and the best laser possible for those implants should consider femtosecond laser cataract surgery.  Studies have shown results that are very promising.
