Femtosecond laser-assisted cataract surgery consists in nuclear lens fragmentation, followed
by ultrasound phacoemulsification of nuclear lens, which is then removed.
It can be assumed that fragmenting the nuclear lens in more pieces could facilitate the
post-laser ultrasound phacoemulsification to extract the lens, with a lesser amount of
The decrease of ultrasonic energy delivered during cataract surgery is beneficial to the
patient because it optimizes the vitality of corneal endothelial cells, which ensure corneal
