  • Applications

    Precision in all facets

    The VisuMax® is extraordinary in all major applications of state-of-the-art corneal surgery. The innovative femtosecond system brings together perfectly coordinated components to provide maximum cutting precision, efficiency, predictability and comfort.

    With SMILE®, the VisuMax enables the fusion of cutting-edge femtosecond technology and precise lenticule extraction to provide minimally invasive vision correction. A refractive lenticule is created in the intact cornea and removed via a small incision. Without ablation. Without a flap. This solution made way for additional treatment opportunities – like small incision lenticule extraction, better known as SMILE. 

    Outstanding results 

    • Small incision of less than 4 mm
    • Side-cut length up to 80% shorter and
    • Cap incision area up to 30% smaller than for a Femto-LASIK flap
    • Implies lower incidence of dry eye syndrome and less nerve transection due to smallest of incisions with no flap
    • Less risk of infections, epithelial ingrowths and flap complications
    • Reproducibility of the lenticule, irrespective of individual corneal characteristics and ambient conditions
    • Excellent predictability, particularly when correcting higher refraction values
    • Efficient treatment process without patient having to switch places

    For Femto-LASIK and the treatment with PRESBYOND® Laser Blended Vision, VisuMax means above all one thing: high-precision flaps. Combined with the excimer laser MEL® 90 and the treatment planning station CRS-Master®, it offers an optimally coordinated system solution for refractive laser surgery – for a convenient workflow, efficient patient management and the best possible results.

    The combination of precision and efficiency 

    • Computer controlled flap parameters
    • Widely adjustable flap diameter, thickness, hinge position, side cut angle
    • High-precision flaps due to high performance femtosecond technology
    • High reproducibility and consistency of flap thickness
    • Easy repositioning of the flap
    • Optimum workflow due to perfectly coordinated system components
    • Smooth, finely structured surface of the stromal bed
    • Prevents unnecessarily raised IOP and thus temporary loss of vision and trauma, due to the anatomically curved contact glass and the nonscleral suction.

    Pivotable patient supporting system

    MEL 90-VisuMax-Combination

    The shared use of the pivotable patient supporting system by the VisuMax and the MEL 90 saves the patient from having to move from one treatment location to another. The patient experiences the surgery as an integrated process. Unnecessary waiting periods are minimized and treatment efficiency increased.



    With the Keratoplasty option, the ZEISS VisuMax becomes a state-of-the-art workstation for customized corneal grafts, enabling smooth lamellar and circular incisions for Penetrating Keratoplasty (PKP), Deep Anterior Lamellar Keratoplasty (DALK) and Descemet’s Stripping Endothelial Keratoplasty (DSEK). High-precision cutting quality and rapid incision progress enable the preparation of precision corneal grafts and ideal preparation of the recipient's cornea. The practical Keratoplasty adapter provides a robust and sterile work surface for preparing corneal grafts and the specially designed curved contact glass (type KP) prevents unnecessary compression of the corneal tissue.

    Precise results

    • High-precision cutting quality in anterior lamellar and endothelial
    • Penetrating Keratoplasty with perfect fit for donor and recipient cornea
    • Precisely predictable incision pattern for greater reliability when
      preparing thin grafts
    • Small spot distance for excellent cutting quality and easy separation of
      the tissue
    • Flexible adjustment of the cutting parameters on the VisuMax

    Maximum efficiency for optimum workflows

    • 500 kHz laser pulse frequency for faster, more precise treatments
      and shorter cutting times (typically less than 60 seconds), even for
      very deep cuts
    • High-quality surgical microscope for visual control at all treatment phases

    Incision for ICR

    Incision for ICR

    When implanting intracorneal ring (ICR) segments, surgeons benefit from the unique advantages of the VisuMaxR femtosecond laser. The VisuMax allows the corneal tunnels for the implantation of intracorneal ring (ICR) segments to be prepared quickly and easily, in the precise position and depth required. The wide range of adjustable parameters and the various combinations thereof give surgeons a unique degree of flexibility. For the first time, it is also possible to create tunnels with an arc angle of less than 360° using a femtosecond laser: With segments of between 90° and 270° partial tunnels can be designed individually, with precision and a high degree of flexibility. This means that individual intracorneal ring segments can also be implanted, without creating unnecessary incisions in the corneal tissue. Thus, tunnels can also be created for mixed ring segments with different geometries.

    New treatment alternatives offer individual benefits

    • The option to select between 0, 1 or 2 trapezoidal access incisions facilitates flexible tunnel access
    • Width and inclination of the tunnel can be freely defined and precisely adjusted to the individual corneal shape and the applied ring geometry
    • Seamlessly integrated into the user interface of the VisuMax, the ICR option provides maximum ease of use
    • Rapid and intuitive entry of the necessary parameters
    • The possibility to save user-defined cutting geometries as reusable  templates increases workflow efficiency
    • Reliability enhancement by graphic visualization of the parameter selection and automatic consistency check of the input parameters
    • The unique contact glass is modelled on the natural shape of the corneal  surface and thus contributes to patient-friendly treatment methods.
    • Excellent control of tunnel preparation and ICR implant insertion as well as complete video documentation using the high-quality ZEISS surgical microscope

    VisuMax highlights

    Curved contact glass

    Maximum cutting precision
    High-precision optics from ZEISS provide an extremely focused laser beam. The result: minimum laser pulse energy at a high pulse frequency for unsurpassed incision control – at precisely the desired depth in the cornea, even with three-dimensional, curved incisions.

    Brilliant visual control
    The integrated, high-quality ZEISS surgical microscope, including digital video camera for live recording of the surgical procedure ensures precise and complete control of each treatment step.

    Incision with precision

    A smart unit
    The ergonomically pivoting patient supporting system ensures maximum comfort. The patient's position is continuously monitored during treatment and the sturdy yet comfortable patient supporting system is automatically adjusted during surgery.

    Efficiency paying off
    With a laser pulse frequency of 500 kHz, the VisuMax® realizes short treatment times. This means more comfort for both physician and patient. In addition, the user benefits from a more efficient workflow and a higher throughput of satisfied patients.

    ZEISS surgical microscope

    A contact glass as ingeniously designed as the cornea
    The surface of the human cornea is curved. Thus, ZEISS contact glasses are curved, too. The three different sizes available (S, M, L) ensure an optimal fit to the anatomy of the eye. The cornea is not forced into a deformed planar, non-physiological shape – and artifacts are avoided in the cutting result, as is unnecessarily high IOP.

    Slit illumination for greater detail
    As a universal workstation for corneal surgery, the VisuMax features integrated slit illumination for monitoring and control immediately after the respective treatment, without the patient having to switch places or change position.

    Achieving objectives with intuition
    The VisuMax can be easily controlled via its touchscreen and intuitive software. An interactive wizard supports the surgeon during all steps.
