Femtosecond laser capsulotomy may lead
to better results with premium lenses

PRAGUE — All lenses, especially multifocal and toric IOLs, may perform better when the capsulorrhexis is created with a femtosecond laser, according to studies at the University of Budapest, Hungary, and the Eye Institute of Utah.
"We used the Alcon LenSx vs. a manual procedure to perform the rhexis in parallel groups of patients, implanted with either monofocal, toric or multifocal IOLs," Zoltan Z. Nagy, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
In the monofocal IOL group, 43% more eyes were within 0.25 D of intended target compared with the manual group. Visual acuity of 20/20 or better was achieved by 73% of the femtosecond eyes compared with 46% of the manual eyes.
In the toric IOL group, a strong correlation was observed between achieved and intended spherical equivalent correction and accuracy of target. Vision of 20/20 or better was achieved by 50% of the femtosecond eyes vs. 20% of the manual eyes.
In the multifocal IOL group, 75% of the femtosecond eyes were within 0.25 D of intended correction compared with 50% of the manual eyes, and 73% of the femtosecond eyes achieved 20/20 compared with 46% of the manual eyes.
These results, Dr. Nagy said, indicate that the image-guided LenSx laser capsulotomy positively influences predictability and effective lens positioning, with significant consequences on the visual outcome.
"Femtosecond laser has made a great entry in cataract surgery and is here to stay," he said.
