Ziemer nanoJoule laser technology

The FEMTO LDV Z8 is designed for maximal precision and gentle eye surgery. Ziemer laser technology is known for:

  • Low energy per pulse in the nanoJoule range for gentler treatments
  • High repetition rate in the MHz range for fast procedures
  • Overlapping laser spots for complete and smooth resections

High-density pulse raster

Different from other lasers, the FEMTO LDV Z Models feature overlapping laser spots that result in:

  • Complete resections free of tissue bridges*
  • Smooth stromal beds**
  • High precision and predictability***
  • Capsule edges that are hard to distinguish from edges seen in conventional surgery****

Laser power adaptable to the tissue

Due to the tissue adapted pulse management system (TAP), the powr is put where it is needed:

  • Adatpion of the laser power to the tissue
  • Lower power in the cornea (e. g. for Z-LASIK)
  • Higher power in the lens (e. g. for hard cataracts)

The FEMTO LDV Z2, Z4, Z6 and Z8 are CE marked and FDA cleared. For some countries, availability may be restricted due to regulatory requirements; please contact Ziemer for details. Presbyopia treatments occur exclusively by a pocket creation and the implantation of a corresponding corneal inlay of a third party. Availability of related corneal inlays and implants may vary according to policy of the individual manufacturers and regulatory status in the individual countries. To comply with FDA regulations, devices for sale in the U. S. do not mention 'Presbyopia' on the panels.
