The femtosecond laser technology that brought new levels of safety, accuracy and predictability to LASIK surgery is also advancing cataract surgery. In our office, we call the procedure Refractive Laser-Assisted Cataract Surgery (ReLACS), but it also is known generally as laser cataract surgery.n traditional cataract surgery, the surgeon creates an opening in the capsule with a small needle and then uses that same needle or a forceps to tear the capsule in a circular fashion.

A picosecond is an SI unit of time equal to 10 â12 or 1 / 1,000,000,000,000 of a second. That is one trillionth, or one millionth of one millionth of a second, or 0.000 000 000 001 seconds.A picosecond is to one second as one second is to 31,710 years.ne picosecond is equal to 1000 femtoseconds, or 1/1000 nanosecond. Because the next SI unit is 1000 times larger, measurements of 10 â11 and 10 â10 second are typically expressed as tens or hundreds of picoseconds. Some notable measurements in this range include:
