  • Energy in the FLACS group was decreased by 33% compared with CPS. Laser time includes docking, suction and laser procedure. Total procedure time includes laser time and knife time.

  • CDE, cumulative dissipated energy; CPS, conventional phaco surgery; FLACS, femtosecond laser-assisted cataract surgery.
