Uses only the femtosecond laser for completing the entire LASIK procedure

No need for an excimer laserPossible only with the VisuMax Laser

from Carl ZeissTwo Procedures

All-Femto Lasik Integrated Solution

Benefits and Advantages

Advantages for the patient

Vision correction w/o corneal ablation• Result quality independent of external conditions• High refractive correction with less induced aberration

Fast single-step treatment• Short period of stress and fear• No need to change stations

Potential for minimal-invasive procedure• Better and faster healing (small incisions)• Preserved biomechanical stability of the cornea• Potential for correction of higher myopes• Lower incidence of Dry-Eye syndrome

(to be proven)

Advantages for the surgeon Differentiation from other LVC providers• Uniqueness of AIO procedure (marketing, positioning)

Workflow improvements• Fast bilateral treatment w/o need to change to excimer

higher patient throughput• Less space requirement

Increased profitability • Premium procedure provides higher margin potential

(ex.: Intralase, Wavefront)• Minimal-invasive treatment may increase demand• Only one laser, with the investment, consumables and

service costs for only laser
