NEW ORLEANS — In a study comparing effective phacoemulsification time and power of different fragmentation patterns in femtosecond laser-assisted cataract surgery, researchers found that a smaller pattern reduced these variables, according to a poster.

The Catalys (Abbott Medical Optics) was used in 125 eyes of 102 patients with either the Quadrant or Complete pattern, according to the poster presented here at the American Academy of Ophthalmology meeting.

The effective phacoemulsification time (EPT) for the Quadrant and Complete groups was 29.47 seconds and 16.31 seconds, respectively, and the mean phaco power was 8.07% and 4.77%, respectively, according to the abstract.

The effect of reduced EPT and power was even greater in eyes with advanced cataract, according to Minoru Tomita, MD, PhD, and Mariko Mita, MD, PhD.

The authors also noted in the poster that the Catalys achieved “excellent results in terms of visual acuity at 3 months, indicating that the Catalys is safe and effective.”
