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 and do not have to be relocated between flap creation and ablation procedures. The surgeon can perform and control the entire procedure from a single working position, without having to move about or changing microscopes. This revolutionary design concept entails several major advantages in clinical practice:
As the FEMTO LDV’s laser energy is deployed from a hand-piece, which is placed on the patient’s eye and manually controlled by the surgeon, a procedure results that resembles the operation of a traditional microkeratome. The sterile single-use parts of the hand-piece, which are provided in convenient, assorted ProcedurePacks, are assembled before the procedure is started and before the patient’s eye is touched. Similarly, the components are disassembled after the complete (usually bilateral) procedure is completed.
For fixation, the hand-piece incorporates a vacuum suction ring, which is available for a range of flap diameters from 8.5 to 10 mm. The ring is mounted over the applanation window on the underside of the handpiece. Positioning, applanation, and suction are controlled visually through the handpiece observation window and the excimer laser's microscope.
