Prior to 2007 there was only one Femto Laser manufacturer player in the market until the launching of the LDV (Leonardo Da Vinci) Femto laser from Ziemer Group AG, Switzerland.
The LDV is the only mobile Femto-Second Laser. Built utilizing the latest laser technologies available worldwide, it is based on a versatile and powerful platform, which can be used for a wide spectrum of corneal surgeries, including All-Laser-LASIK, Corneal Rings, LamellarKeratoplasty and others. 
Due to its small size and flexibility, the LDV can be easily integrated into all refractive laser centers, regardless of Excimer laser type or surgical patient bed used.
Compared to other available Femto-lasers, the LDV operates at a much higher repetition rate (Megahertz as opposed to Kilohertz), much lower Energy per pulse (in the range of Nano-Joules), and uses optics that deliver very tightly focused and small laser treatment spots for maximum tissue disruption without thermal or radiation effects to the surrounding tissue.
With these low energies the Ziemer’s LDV cutting process creates smaller gas bubbles which disappear immediately the flap is lifted. Furthermore, no significant OBL (Opaque Bubble Layer), TLSS (Transient Light Sensitivity Syndrome) or energy-related DLK complications are reported – as they are with other systems.
As well, unlike other systems, thinner (>90 micron) flap creation is now safely possible with the LDV.
From a technical side the laser, as its laser source is a unique one-stage process (as opposed to other systems which are two-stage with the laser source is pulsed from one module and amplified in another) is very stabile and easier to service, repair and maintain than is reported with other systems.
This exciting new Femto Laser platform gives your refractive center many advantages:
 
• Excellent visual outcome.
• Smooth Surface cut with large enough Stromal bed.
• Smooth flap edges for optimal flap repositioning and closure.
• Reproducible, planar flaps.
• Rapid healing and fast visual recovery.
• Minimal laser downtime with less surgical schedule interruption.
