ASCRS 2024: Ease of opening arcuate incisions created with a dual pulse femtosecond laser


At the ASCRS meeting in Boston, Dan Tran, MD, details his presentation on incision quality and clinical outcomes of femtosecond laser

At this year's ASCRS meeting in Boston, Massachusetts, Dan Tran, MD, presented his paper, "Incision Quality and Clinical Outcomes of Femtosecond Laser-Assisted Arcuate Incisions Created during Cataract Surgery." In this video, he shares key takeaways from his presentation, including a grading scale for incisions created with femtosecond laser.

Hi, my name is Dan Tran. I'm the medical director and founder for Coastal Vision Medical Group in Southern California. I'm very happy to be here at ASCRS 2024. I just finished on the presentations of a clinical study looking at the effectiveness and ease of opening efficacy of the femtosecond laser assisted arcuate incision using the Lensar ALLY system. And the study is basically focused on how easy it is to open up an arcuate incision using the femtosecond laser, the Lensar ALLY system, using a dual pulse system. Basically there are two different pulses, one at 1500 femtosecond to basically dissecting and cutting the lens, and the shorter pulse of 320 femtosecond for ease of cutting and efficacy on the cornea. And we look at the ease of opening up the arcuate incision to reduce astigmatism on patients undergoing cataract surgery. We're using a grading scale of one to five, where five is really easy, where the incision is basically fully open without touching the incision. And then four would require very slight touch with a blunt instrument to open the incision. Three would be using the blunt instrument, but have to use some force, and one is if the incision is not open at all. And we found that the outcome shows a score of about 4.35 ± 0.6, in terms of the ease opening. So most incisions either spontaneously open or are very easy to open with a blunt instrument. And this is possible because of a 320 femtosecond pulse with the Lensar ALLY system to be able to make the astigmatism reductions [with] corneal incision. Thank you.
