ZEISS MEL 90 Advanced excimer laser technology

Specially designed for the needs of the modern refractive surgeon, the MEL® 90 excimer laser from ZEISS incorporates reliable outcomes, proven safety and individually configurable options. Unique product features like the FLEXIQUENCE® switch function (250 Hz / 500 Hz), the Triple-A ablation profile and the outstanding intra-operative ablation speed create entirely new excimer laser treatment prospects.

  • Reliable outcomes
  • Fast ablation speed
  • Easy to use

Reliable outcomes

A ZEISS MEL 90 specialty is the Triple-A Advanced Ablation Algorithm. It is a single ablation profile for a wide range of sphero-cylindrical (SCA) corrections that simplifies treatment planning. Triple-A offers a high degree of precision, reproducibility and predictability, as well as advantages such as the controlled induction of spherical aberrations and tissue-saving ablation.

Its preinstalled functions also offer surgeons optimal support for achieving excellent treatment results and gentle treatments of standard, higher and lower level of ametropia as well as astigmatism. These features ensure a successful treatment of the following procedures: Femto-LASIK, LASIK, LASEK, PRK and PTK.

Fast ablation speed

With its unique FLEXIQUENCE switch function (250 Hz and 500 Hz operation) and additional configuration options, the ZEISS MEL 90 is a true customized power package. When performing LASIK for myopia at 500 Hz, the ZEISS MEL 90 can intra-operatively ablate 1 diopter in as little as 1.3 seconds. The same short treatment time and full laser speed also apply for treatments of presbyopic patients with PRESBYOND1.

Intuitive system guidance and speedy treatment planning allow for additional time savings. The ZEISS MEL 90 excimer laser technology is equipped with an active eye tracker which has an excellent response time, providing a high level of treatment safety with very stable results. The advantageous FLEXIQUENCE function is properly supported by the adaptive sensor-controlled CCA+ plume removal system.

Easy to use

As a true team player, the ZEISS MEL 90 excimer laser greatly simplifies the interactions between the surgeon, the assisting staff and the system technology. The excimer laser can be configured to precisely match the surgeon and OR team`s needs. The ZEISS MEL 90 is a highly reliable system requiring very little service maintenance. The system's simple, intuitive graphic user interface supports fast treatment procedures. The new MEL 90 patient bed LS Comfort 80 combi enables the combination with the next evolution of femtosecond lasers VISUMAX 600 or VISUMAX® 800.

Easy to use

High-quality equipment for an optimized workflow

The touch screen can be flexibly positioned wherever it is needed and provides the surgeon with a good ergonomic sitting posture throughout the operation. A second, optional touch screen allows the assistant to start preparing the next therapy while the surgeon is still concluding post-operative care for the previous treatment. An HD video port, network printer connection and PDF export capabilities offer additional workflow support. With the proven fluence test, laser calibration is very quick and easy.

Furthermore, the workflow-optimized compatibility of the MEL 90, VisuMax® , VISUMAX 800, and CRS-Master® and Refractive Workplace® from ZEISS ensures a high level of consistency within your practice.

Digitally connected to ZEISS Refractive Workplace

Treatment plans for LASIK, PRK, femtosecond LASIK or treatments with PRESBYOND can be created with ZEISS Refractive Workplace2 and transferred simply by network connection. The MEL 90’s connectivity to FORUM® enables remote treatment planning outside the operating room. You can also store treatment protocols and videos in network storage locations and the FORUM archive for documentation and review or directly request technical service support. In addition to that, the excimer laser automatically delivers device status information like log files to the central device management system via a remote service connection.

With the MEL 90’s new connectivity features, it becomes a fully-integrated part of the new Corneal Refractive Workflow enabling you to streamline your practice workflow.
