Lamellar and penetrating keratoplasties

Using low energy in each laser pulse in the nanoJoule range, the FEMTO LDV Z Models are the ideal tools for tailor-made keratoplasties ranging from penetrating to ultra-thin lamellar grafts.



Lamellar keratoplasty

In the past, outcomes of LK procedures have been hampered by the difficulty of obtaining a smooth, even stromal bed to receive the graft. With the FEMTO LDV Z Models excellent cutting performance, perfect resections may be performed even if this requires cutting through opacified or scarred tissue.


  • Round and oval resections 
  • Angled edge as desired by surgeon
  • Resection depths of 50 - 850 micron


  • Ultra-thin lamellae possible

Penetrating keratoplasty

This module allows surgeons to perform a penetrating keratoplasty for both patient and donor corneas. By means of an artificial anterior chamber designed specifically for the FEMTO LDV systems, perfect donor buttons can be excised. Options contain mushroom, top-hat and straight patterns.

With the FEMTO LDV Z8, the integrated OCT system enables for clear visualization of previous resections and scars to enhance surgical planning. 

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.
