Lenticule Extraction with the FEMTO Z8

The new Lenticule application by Ziemer is called CLEAR and stands for: 

E  Extraction for
A  Advanced
R  Refractive Correction

The completely new developed and proprietary application is intended for the treatment of Myopia and Astigmatism.

The new Lenticule application can be purchased through a software upgrade and is an integrated part of the FEMTO LDV Z8 and the new FEMTO Z8 NEO platform.

Lenticule Extraction redefined: CLEAR

Benefit from various possibilities in faciliating the Lenticule separation and extraction. 

The advantages are:

  • Centration after docking
  • Trusted vacuum as known in Ziemer systems
  • Guiding tunnels for easy Lenticule separation
  • Multi incision options:
    2 incisions during initial learning curve
    1 incision for experienced surgeons
  • Intraoperative OCT (optional)
  • Proprietary scan pattern with overlapping spots
  • FEMTO LDV low energy concept

What's different with Ziemer?



As a pioneer in low energy femtosecond laser treatments, Ziemer’s low energy concept provides maximal precision, minimal tissue damage, minimal side effects, less inflammatory response and is known to contribute to fast visual recovery.

Centration Options

  • Easy centration on the eye
  • Repositioning of Lenticule under suction is possible
  • Compensation for cyclotorsion
  • Different centration options are possible:
    – Pupil Center
    – Fixation Light
    – Corneal Marks

Adjustment Options

Adaptable placement of incisions

  • Choose between 1 or 2 incisions
  • Free choice of position
  • Intraoperative changes are possible
  • Optimization for left or right handed surgeons

Low energy concept

Thanks to the Ziemer handpiece there is a very short working distance to the eye. Therefore, a high focusing power can be achieved and only very little energy per pulse is needed. This allows for small overlapping spots resulting in a smooth cut – only possible with the Ziemer FEMTO LDV's low energy concept.
