PRESBYOND

Laser Blended Vision
The MEL 90 is also a first-rate platform for treating presbyopic patients. With the optional PRES BYOND® Laser Blended Vision module, MEL 90 offers an advanced and true binocular laser correction method that far exceeds the limitations of conventional monovision.

The next level in eye care excellence
PRES BYOND Laser Blended Vision is an individualized treatment approach in which pre-operative spherical aberrations are used to calculate the ablation profile. The functional age of the eye can also be used for the calculation. This results in an increase in the depth of field of each individual eye, creating a customized fusion of the two images for near and distance vision – the so-called “Blend Zone.”

The method enables clear sight at all distances – near, far, even intermediate – and for a wide range of indications from -8.0 to +2.0 D. Emmetropic as well as astigmatic presbyopic patients (up to 2.0 cyl) can also be treated. PRES BYOND Laser Blended Vision is tolerated by a higher number of patients than conventional monovision – up to 97%* as compared to only 59–67%**. In many cases, patients can read without glasses the very same day.

Patients expectation precisely
Priority one, of course, is the satisfaction of our patients, which is largely dependent upon the safety and reliability of the treatment. The MEL® 90 combines high-quality elements and performance to help us optimally fulfill our customers’ requirements.
• MEL 90 outcomes
The MEL 90 can be precisely tailored to the individual needs of the modern refractive surgical practice. Its preinstalled functions also offer surgeons optimal support for achieving excellent treatment results.
• MEL 90 atmosphere
The unique, sensor-controlled CCA+ plume removal system supports optimal atmospheric conditions around the patient‘s eye – thereby also significantly improving the predictability of the results.

• Safe eye tracking
The MEL 90 is equipped with an active eye tracker with an excellent response time to provide high-level treatment safety with very stable results.
• High patient comfort
In combination, short treatments and seamless procedural flow help to enhance the patient experience. The comfortable patient supporting system ensures stress-free and stable positioning throughout the entire OR procedure.

• MEL 90 time
When performing LASIK for myopia at 500 Hz, 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.
• Advanced system guidance
The systems‘ simple, intuitive graphic user interface supports fast treatment procedures. You can flexibly adjust the touch screen to wherever you need it and, thus, maintain a good ergonomic sitting posture throughout the operation.

• Touch screen or keyboard control
For additional convenience, you can choose to make entries either per touch screen or keyboard.

• MEL 90 teamwork
Two workstations
Truly exceptional - as a true team player, the MEL 90 has a second, optional touch screen on the system, which greatly simplifies the interaction between the surgeon, assistant staff and system technology. When equipped with a second workstation, it can be configured to optimally complement the treatment routine of the OR team.

• Easy calibration
With the proven fluence test, laser calibration is very quick and easy.

• Very service friendly
The MEL 90 is a highly reliable system requiring very little service maintenance. The unique beam path evacuation eliminates the need for flushing gas.

• Seamless data integration
Patient data transfer is very easy thanks to the seamless interaction between the MEL 90 and other refractive platforms from ZEISS – VisuMax® and CRS-Master®.
