Can the infrared laser energy of the femtosecond laser damage the eye?
Due to the ultra-short treatment time of the femtosecond laser – somewhere in the range of 500-750 billionth (10-15) seconds, very little energy is required to achieve photo disruption (the “cutting” action of the laser). The exposure period is so short, and the laser so precise that any tissue beyond several micrometers of the treatment area is completely unaffected.
