VisuMax Technology
The "all-in-one" bladeless LASIK solution from one competent and committed partner
Carl Zeiss Meditec has integrated two of the most technologically advanced refractive lasers, the MEL 80 excimer laser and the VisuMax femtosecond laser, as a seamlessly coordinated system for refractive laser surgery. This integrated system handles individualized treatment planning and precise flaps, along with highly-precise refractive corrections to ensure convenient workflow, efficient patient management, and best practice treatment results
How precision fits into your daily routine
Perfect ergonomic design begins with the contact interface. Because patients retain their ability to see during the surgical procedure, they are able to actively cooperate throughout the entire laser treatment. As a universal workstation for corneal surgery, the VisuMax features a high-quality Zeiss surgical microscope and integrated slit illumination. During the surgical procedure, the VisuMax provides audio cues that allow you to fully concentrate on the laser therapy.
Freeing up your hands
There are only a few steps from the treatment planning to laser therapy. The VisuMax intuitive software offers surgeons complete freedom to focus on the treatment. Patient positioning between the surgical microscope and the treatment position is fully automated.
The touch screen and intuitive software enable easy system control, and interactive features provide additional support. Preset treatment programs offer standardization, and patient-oriented planning gives surgeons the freedom they need to operate.
Also featured is an integrated video camera equipped with a DVD recorder to provide comprehensive documentation.
Economy
Thanks to the VisuMax system’s robust, low-maintenance system, there are no parts that require routine replacement. Even though the system has no permanent standby mode, it is always ready for use, which makes it more economical to operate and environmentally friendly.
Equipped to outperform
The VisuMax is designed to be the superior flap cutter with extremely high precision of incisions in 3D shape. Benefits include predictable, accurate flap thickness and dimension with a flap bed parallel to the corneal surface, and a steep side cut angle. These features result in a better fit for flap repositioning. Tissue disruption can be reduced to submicron volume with precise focusing and sensitive energy controls.
The positioning of the curved contact interface of the VisuMax is unique. Contact and suction to the patient’s eye occur only on the cornea. The contact glasses are curved to comfortably rest against the patient’s cornea. Various size contact interfaces enable optimal fitting for individual eyes, thus preventing unnecessarily high intraocular pressure while eliminating the patient having vision loss commonly associated with suction. Thus, the patient can actively cooperate during the entire laser treatment.
A fully device integrated suction system ensures that suction is only applied to the cornea during the actual laser treatment. Automatic corneal suction is continuously monitored throughout the surgery and takes only seconds longer than the actual laser incision itself.
Centration is supported with several features including an internal fixation target for the patient designed to attract their attention, self adjustment of the eye during docking to contact glass, easy to find visual axis for treatment positioning, and automated adaptation to patient eye refraction.
The procedure can be continued for the second eye without moving the patient back to the observation position providing an improved workflow.
Streamlining workflow
Thanks to a table that pivots between the VisuMax femtosecond system and the MEL 80 excimer laser, patient transfers between surgical steps are no longer necessary. The patient experiences the surgery as an integrated process resulting in a high comfort level for the patient and surgeon Unnecessary waiting periods are minimized and treatment efficiency increases.
Systems that communicate with each other
The MEL 80 excimer laser and the VisuMax allow for a highly efficient clinical workflow. This integrated solution offers surgeons the potential to expand networking capabilities with a continuously enhanced and efficient flow of data and individualized patient treatment. Data is transferred by a local network connection from the MEL 80 to the VisuMax. This smooth and seamless system integration is designed to accommodate future options.
Multi-faceted surgical options
The VisuMax provides flexible incision geometry. Intuitive software makes it possible to conveniently adjust all patient-specific treatment parameters. Thanks to innovative femtosecond technology, precise flaps are just the beginning of potential corneal surgery applications. The VisuMax is designed to become the corneal surgery workstation for a large spectrum of procedure options.
Targeting new patient groups
Accurate and predictable incision guidance and minimal variation in flap thickness result in greater safety when treating patients with thin corneas or high ametropia…patients for whom refractive surgery may have been contraindicated in the past.
Peace of mind
There is simply no safer, more accurate way of guiding corneal incisions. High-precision Zeiss optics allow for faster, more accurate incision beam guidance with minimum laser energy (typically <300 nJ), and a high pulse repetition at the rate of 200 kHz enables unparalleled incision beam guidance perfection, precisely to the desired ablation depth. The typical spot distance is 6 microns. As a result, tissue outside of the defined area remains untouched.
Numerous safety features have been built into the VisuMax including:
- A fully automated force control that activates during eye docking
- Closed loop force sensing and automated adjustment during therapy
- Fully integrated vacuum system
