Advantage Ziemer Femto LDV Lasers
Among the many innovations in Ziemer’s laser technology is a revolution in the size of our unit. Our LDV models have, by far, the smallest footprint in the industry and the best mobility.
It’s not just a convenience. It’s a critical factor that enables you to perform more procedures in different rooms with the same equipment. We make the economics work for you.
The carriage under the laser allows it to be “piloted” by one person. The unit, without any disassembly, may also be moved in a standard wheelchair accessible van to other locations.
Short learning curve
While you and your staff will receive thorough training from Ziemer, you’ll discover a highly intuitive software interface and mechanics. In the OR, Ziemer innovation assists you in other ways. You won’t have to guess if suction is engaged, the onboard computer will prevent the laser from firing.
Multiple Procedures: Cataract (FLACS), LASIK, Pockets, and Intracorneal Rings
The clinical advantages of femtosecond cataract surgery over conventional procedures:
- Better visual outcome at post-op 1 week and 6 months1
- FLACS capsulotomy results in a more stable refractive result and less IOL tilt and decentration than manual2
- Reduced complications such as fewer anterior tears3
- Significantly reduces phaco energy1
- Endothelial cell count preserved with low energy femto4
- Controlled capsule diameter which impacts strength5
- Advantageous in cases with weak zonules (e.g. PEX, trauma)6

Clinical studies show that FDA-approved femtosecond lasers create pristine excellent corneal flaps for all-laser LASIK. They also reduce the risk of flap complications associated with mechanical microkeratomes.

The Femto LDV’s lower energy reduces inflammation and the opaque bubble layer (OBL) in the deep stroma. “The amazing thing was that we had no DLK. With other technology we almost always had periperal DLK and it is quite rare now that we have Ziemer,” Gary Wilson, M.D.
This phenomenon caused by other femtosecond lasers can lead to flap problems and affect visual outcomes. “In our 1000 cases I haven’t had a significant case of OBL. There is no laser as good as the Ziemer,” says Luke Rebenitsch, M.D.
Articulating arm simplifies patient alignment
No more sliding and aligning patients under a fixed laser head. Just pull the patient alongside the Ziemer LDV Femto, and float the articulating arm and hand-piece directly to the patient for exact and efficient alignment. Precision is further increased by having the objective lens millimeters above the patient.
Auto-calibration and start-up time.
Many Ziemer lasers are used in multiple rooms on the same day. Fortunately, our FEMTOs auto-calibrate in approximately 10 minutes. If the laser is started up cold, it’s ready to operate within an hour. More uptime, greater use.
The reliability of solid state architecture
Ziemer’s femtosecond lasers calibrate faster and more tightly, because their solid-state design is resistant to big changes in temperature and humidity. This has a direct impact on our speedy calibration times.
Reduce collateral tissue damage
Ziemer’s Femtosecond Lasers are designed to be gentle on the eyes. They deliver:
- Precise, low-energy pulses at an ultra-high repetition rate greater than 1 megahertz with a duration of 3/10,000 of a nanosecond.
- Fast – A higher repetition rate, greater than 1 mHz, creates incisions for faster and cleaner surgery.
- Overlapping spots – This unique continuous method of overlapping low-energy laser spots speeds up procedures, and eliminates tricky tissue bridges. Clean incisions minimize complications because tissue separates easily without tugging.
