160 kHz for the LASIK-flap procedure (**Figures 10**–**12**).

The VICTUS system currently uses two components for laser docking: a lowpressure silicone suction ring and a curved interface cone. Adaptation of the curved interface cone is controlled by intelligent sensors, which change pressure levels exerted on the eye depending on the treatment. The image capturing system is a spectral-domain OCT that takes real-time images and identifies anterior segment structures. The surgeon can manually locate the area of photodisruption in the

Flaps in refractive corneal procedures and incisions are also possible, making it a versatile femtosecond laser system. The laser source operates at 80 kHz for the FLACS procedure. The optical-acoustic-modulator included allows modulation in the laser pulses' frequency: it can change from 80 kHz for the FLACS procedure to

The device is the first mobile cataract femtosecond laser that can be easily suit in the operating room. Ziemer has developed a liquid-filled nonapplanating interface which adheres to the eye with minimal suction and thus avoids corneal folds. The FEMTO LDV Z8 employs a combination of two imaging systems for real-time visual control of the docking process and of the positioning of dissections: the TopView®, a high-definition camera which provides visual control of the alignment of the patient
