Evolving femtosecond laser technology leads to increasingly better outcomes
Ljubljana, SLOVENIA — Femtosecond laser-assisted cataract surgery with the Lensar laser system is a safe and fast procedure, and continuous evolution will lead to further improvement, according to one speaker.
“When we started in 2012, we felt like entering a new galaxy, where we could aim at an extremely high level,” Detlef Holland, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
The new second-generation disposable patient interface device, which improves suction and centration shift, has made docking easy and eye fixation stable.
“Now that we have completed our learning curve, suction time is only 2 minutes, which results in the eye being very quiet the next day,” Holland said.
Capsulorrhexis tears and capsule ruptures due to tears occurred in a few cases during the learning curve.
“They no longer occur since I have changed my technique for removal of the rhexis button,” Holland said.
Comparison of the 700 femtosecond laser procedures performed to date with standard phaco showed superior results in terms of rhexis shape and centration, IOL centration, ease of nucleus fragmentation and ultrasound time.
Relaxing incisions are a further option, “very easy to plan on the touch screen, fast produced by the laser,” Holland said. First results showed a 50% reduction of astigmatism.
“We are now setting up a study with our own nomogram for astigmatic correction,” he said.
