Femtosecond laser

Swiss Ziemer engineering have produced the Leonardo Di Vinci (LDV) femtosecond laser for the current application of making the flap in laser vision correction. Faster speed and lower energy produce results that are significantly better than the current system, Intralase and other systems that use "amplification" for dissection. The LDV allows for speeds in the mega hertz range, nano joule energy with smaller spot size and millimeters of focal distance to accomplish a complete smooth dissection. This translates into better vision by providing a planar, dry, bubble free (OBL) treatment surface for the excimer laser. This unique technique is termed Zlasik for the combination of the highly smooth dry treatment surface without tissue "tufts" which are the an unavoidable feature of high energy, low repetition lasers that use amplification. The physicist Holgar Lobatschowski with the team under Frank Ziemer are to be given credit for this major advancement in the field of refractive surgery and for creating the lamellar dissection tool that will lead innovation in the the coming years in Ophthalmology.
