The house of technology

Our house of technology uniquely represents the package of the core competencies we have built and accomplished over the years. By structuring these attributes “under one roof”, we have the opportunity to offer tested and studied cutting edge technology straight from our labora-tory to your hands faster and more efficiently than ever before.

From our solid foundation we have created three distinct towers, each one specifically focused on detailed appli-cations of our femtosecond lasers:

Cornea, Presbyopia, Cataract

Femto cornea tower

This tower represents gentle but ultra-precise treatments on the cornea. Every floor symbolizes its own appli­ cation: from crystal clear Z-LASIK to advanced corneal surgery, with various indications highlighted:

  • Z-LASIK – tapered and customized flaps
  • Customizable tunnels for intracorneal ring segments
  • Lamellar and penetrating keratoplasty
  • Corneal blindness treatment option
  • Arcuate incisions

Femto presbyopia tower

The middle tower is dedicated to the challenge of presbyopia. Designed to improve the daily life of your patients, several applications support the precise techniques and intricate surgery of inlays. Available treatments are:

  • SIM LASIK™ – all-in-one combined Z-LASIK plus presbyopia correction
  • Post-LASIK treatments – highly precise pocket resection below an existing flap
  • Tailored pocket software for intrastromal inlays for presbyopia treatment

Femto cataract tower

Femtosecond laser assisted cataract surgery is supported by the third tower. A variety of applications assist you in performing the actual surgery. Our goal with this tower is to have no compromises in precision and the highest level of quality control is maintained on both the cornea and the lens.

  • A new Z Model, fully equipped to assist you in performing femto-cataract surgery, is already under development.
  • The FEMTO LDV Z6 is ready for upgrading to femto-cataract capability when it becomes available
The application towers are constantly growing and being developed as we continue to learn. Although some treatments might not be available in your country yet, be confident that your platform is already designed to accommodate these applications. Versatility makes it happen!

FEMTO LDV femtosecond surgical lasers

Unique femtosecond technology

A technical revolution in ocular surgery

With their unique operating concept, the FEMTO LDV systems have already become the technology leader among all femtosecond lasers.

Other femtosecond lasers currently in the market are based on the same basic technology that has been used in femtosecond lasers since they were introduced to ophthalmology several years ago. Laser sources operating at tens to hundreds of kilohertz are fed to amplifiers­ to achieve high pulse energies to create large cavitation bubbles to disrupt corneal tissue. This inevitably induces mechanical stresses in the eye.

Ziemer’s proprietary FEMTO LDV systems are based on a radically different technology. Operating with very low pulse energy and very short pulse width but very high pulse frequencies in the megahertz range, the threshold for tissue disruption is reached without requiring an amplifier. This low energy delivery has turned out to be the most relevant factor for a gentle tissue resection.

  • Lowest pulse energy (nJ range)
  • Highest pulse repetition rate (MHz)
  • Shortest pulse width
  • Minimal side effects
  • Minimal mechanical stress
  • Cleavage-free tissue dissection

Only custom-made components and an integral system Design can bring this performance

Microscope lens quality optics

The unique design of the FEMTO LDV laser delivery system features a hand-piece with a highly sophisticated optical system: an optomechatronical masterpiece. These custom made microscope lenses with high numerical aperture assure a perfect focus and ensure high precision in cutting depth:

  • Very high numerical aperture
  • Extremely short focal depth
  • Wave-front optimized optics
  • Significantly fewer gas bubbles
  • Tissue preservation
  • Quiet eyes, free of edema

Laser energy is delivered to the eye through an articulated arm and a hand-held scanning device, which affords a direct view of the cornea.

High Density Pulse raster

The precision optics, the custom made laser sources and a proprietary high speed scanning system generate tightly focused low-energy laser pulses in an overlapped pulse raster. This results in a complete and smooth resection with no interstitial, un-dissected spaces and minimal complications.

  • Flaps can be easily lifted (no “tissue bridges”)
  • Excellent stroma bed quality
  • Minimal complications such as opaque bubble layer (OBL), transient light sensitivity (TLS), or laser-induced diffuse lamellar keratitis (DLK)



The productivity tool that integrates into your surgical workflow.

  • Universal workstation – fits with every excimer
  • Simplified patient flow

Workflow integrated solution:

Due to its unique hand-held laser delivery system, which is attached to an easily maneuverable articulated arm, patients can be treated on the patient bed of the excimer laser. Neither the patient nor the surgeon needs to move, and the treatment is a single, uninterrupted process with no waiting time.

This makes Z-LASIK a more comfortable and less stress­ ful for the patient.

  • Single working position for the doctor
  • No need to move the patient


True mobility. The first truly mobile femtosecond surgical laser, designed to meet your needs.

  • The FEMTO LDV Z Models are designed to be moved between different surgical rooms:
    9.00 AM – Z-LASIK, 11.00 AM – Presbyopia,
    2.00 PM – Keratoplasty, etc.
  • Multi-site universal system: With the FEMTO LDV Z Models this is not just possible – it’s easy

HD visual control

A large high definition (HD) flat monitor shows a real-time image of the eye. This gives the surgeon full tactile and visual control while observing the treatment field both through the microscope and the TopView camera built into the handpiece.

  • Professional HDR (High Dynamic Range) imaging
  • Multiple screen technology
  • Easier centration
  • More precise positioning
  • Improved ergonomics, improved usability

Outstanding clinical results

Excellent vision

Based on clinical experience from over 1.5 million successful Z-LASIK procedures, the FEMTO LDV systems stand out as the femtosecond lasers with a remarkably low complication rate.

The FEMTO LDV Z Models provide the basis for excellent outcomes in laser vision correction.

  • Large corneal flaps
  • Uniform, reproducible flap thickness
  • Capable of thin flaps (SBK)
  • Full computer-controlled suction

Z-LASIK – the gold standard

With this method, the flap resection is created in a planar mode (xy-plane), at the requested depth. Fully-adjustable hinge size and position.

  • Natural curvature flap edges
  • Smooth, self-sealing flap edges


This new Z-LASIK method performs the resection in a three-dimensional mode. Each flap can be customized to accommodate the desired geometry.

  • Round and oval flaps
  • Angled edge as desired by surgeon

Very fast visual recovery

In conjunction with state-of-the-art excimer lasers, the FEMTO LDV systems achieve superior short-term results as well as excellent long-term visual outcomes in femto-LASIK procedures.

The graphic compares binocular uncorrected distance visual acuities (UDCVA) immediately at the conclusion of surgery and at 15, 30 minutes, 1, 2, 4 hours and 1 day postoperatively. The results speak for themselves: right after surgery, uncorrected visual acuity of 20/40 for 80% of the patients. After only 4 hours, 100% had 20/20.

Truly safe for ultra thin corneal resections
