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.

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 propperly 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.
