New femtosecond laser enhances accuracy, customization of LASIK flap creation

MILAN — The combination of the newly released Ziemer Femto LDV Z4 femtosecond laser and the Schwind Amaris excimer laser enhances accuracy, predictability, safety and efficacy in LASIK, according to one surgeon.
“What’s new with this femtosecond laser is that it can now move the focused laser beam in the x, y and z axis, allowing surgeons to really individualize flap creation as far as diameter, shape, hinge position [and] side-cut angle are concerned. There’s no longer the need to change intershield [spacers],” Minoru Tomita, MD, said at the European Society of Cataract and Refractive Surgeons meeting.

Tomita presented the results of a first series of 70 eyes of 35 patients treated between January 2012 and May 2012.
Attempted flap thickness was 90 µm or 100 µm. To assess thickness accuracy, ultrasound pachymetry was used to measure central corneal thickness before surgery and after flap creation, lifting the flap.
“The mean difference from attempted flap thickness was less than 1 µm,” Tomita said.
Visual and refractive results were very good. At 3 months, all eyes had achieved 20/20, 93% were within 0.5 D of manifest refraction spherical equivalent, and 100% were within 1 D.
