Therefore, ROS can be affected as a response to femtosecond
laser and in turn induce calcium increase and thus influence relative signal pathways and cellular processes like cell death .
laser cataract surgery: updates on technologies and outcomes.
Arturo Betancourt, MD, president and medical director of Baltimore Washington Eye Center, says the Femtosecond
laser al lows the consolidation and conversion of the many skill-intensive steps of cataract removal into a more predictable procedure.
laser is very similar to the Nd:YAG laser.
Commenting on his first clinical experiences with CUSTOMLENS, Prof Gerd Auffarth, University of Heidelberg, Germany, said, "Being able to perform femtosecond
laser-assisted cataract surgery with the TECHNOLAS system is a remarkable step forward in femtosecond
Lasers can now routinely generate pulses lasting just millionths or billionths of a second, or femtoseconds
, so scientists have begun to produce what amount to snapshots of fleeting, intermediate stages of chemical reactions.
Due to its short pulses--lasting one quadrillionth of a second--a femtosecond
laser can vaporise material precisely, without heating the surrounding matter.
Laser Quantum has added two new products to its Gecco and Venteon femtosecond
oscillator ranges: the Gecco Power and Venteon Boost.
Laser Surgery in Ophthalmology (online access included)
Currently, the introduction of femtosecond
laser-assisted cataract surgery (FLACS) has changed the way of undertaking cataract surgery by automating key steps in the surgical procedure [6, 14, 15].
laser has been introduced in refractive surgery to create a thin-hinged corneal flap without using any blade.
