IOLMaster 700

Next generation biometry from ZEISS

Coming soon: Total Keratometry

With a software update due for release in 2018, the IOLMaster® 700 from ZEISS with SWEPT Source OCT technology will allow you to directly measure the posterior corneal surface and to incorporate these measurements in classic IOL power calculation formulas.

  • Highlights

    Get fewer refractive surprises

    Tilted lens

    Detect unusual eye geometries
    The ZEISS IOLMaster 700 provides a full-length OCT image showing anatomical details on a longitudinal cut through the entire eye. Thus unusual eye geometries, such as a tilt or decentration of the crystalline lens, can be detected. If left undetected, such critical details can lead to an unsatisfactory post-operative visual experience.

    Fixation check

    Detect poor fixation
    The unique Fixation Check provides you with more confidence in optical biometry. Can you see the foveal pit? If so, you can reduce the risk of refractive surprises due to incorrect measurements caused by undetected poor fixation. If not, you can educate your patients to always fixate on target.

    Visually verify your measurement
    All measurement calipers are shown on the full-length OCT image. Now, for the first time in optical biometry, you can visually verify what structure of the eye has been measured. Complex interpretation of A-scans are no longer necessary. Thus, potential sources of errors are eliminated.

    Benefit from the integrated Barrett Suite

    The ZEISS IOLMaster 700 fully integrates the latest Barrett formulas into one suite. Barrett Universal II, Barrett True-K and Barrett Toric – formulas which also incorporate the influence of the posterior corneal surface.11,12,13

    Improve your refractive outcomes

    IOLMaster 700 repeatability

    Outstanding repeatability
    Repeatability is essential for good refractive outcomes. Thanks to its unique SWEPT Source Biometry with 2,000 scans per second, the repeatability of the ZEISS IOLMaster 700 is absolutely outstanding.

    IOLMaster 700 ULIB

    Get the broadest basis of clinical data
    Leverage the complete "User Group of Laser Interference Biometry" (ULIB) database! You will find optimized lens constants for more than 270 IOL models based on the data from over 50,000 cataract surgeries specifically collected for the IOLMaster. This will help you to improve your refractive outcomes.2

    700 telecentric keratometry

    Unique telecentric keratometry

    ZEISS is the only company that offers an optical biometer with telecentric, and thus distance-independent, keratometry. Its smart optical configuration allows robust and repeatable measurements – especially with restless patients – for superior keratometry measurements.

    Optimize your workflow

    >99% cataract penetration rate
    Thanks to its unique SWEPT Source Biometry, the cataract penetration of the ZEISS IOLMaster 700 outperforms that of A-scan optical biometry. A comparative clinical study with more than 1200 eyes showed that the
    ZEISS IOLMaster 700 achieves a cataract penetration rate of more than 99%. As a result, the number of ultrasound cases may be reduced by 92%5 saving you valuable time and lowering the risk of refractive surprises caused by imprecise ultrasound measurements.

    Get indications for macular pathologies
    The Fixation Check can help you to identify macular pathologies such as macular holes, epiretinal membranes, and age-related macular degeneration in your daily routine. As the ZEISS IOLMaster 700 is clearly not intended to be used for diagnostics, findings need to be verified and pathologies diagnosed with a dedicated retina OCT. Nevertheless, in high-volume practices the ability to detect these eyes preoperatively can be invaluable.6,7,8,9

    IOLMaster 700 Haigis Suite

    Toric IOL power calculation made easy
    In the new Haigis Suite, the ZEISS IOLMaster 700 provides the first on-board all-in-one solution for toric IOL power calculation. It combines the well established Haigis formula, the Haigis-L formula for post-LVC cases, and the new Haigis-T for toric IOL in one powerful tool. There is no need to key-in data into the IOL vendors’ online toric power calculation tools.

    IOLMaster 700 usability

    Fast and easy to use

    Thanks to its SWEPT Source Biometry, you can measure both eyes in less than 45 seconds10 (watch video). The multi-touch screen and the new graphical user interface allow for gesture control of the device like you are used to from your smartphone or tablet computer. Alignment assistance functions make the results largely independent from the user and therefore easy to delegate.

    IOLMaster 700 ZEISS Cataract Suite markerless

    Implant toric IOLs markerless – ZEISS Cataract Suite markerless

    The ZEISS IOLMaster 700 is part of the ZEISS Cataract Suite markerless. It acquires a reference image in case of astigmatism during routine biometry. The image of the eye is taken along with the keratometry measurement, all with one device. Both reference image and keratometry data are transferred to the CALLISTO eye® computer assisted cataract surgery system from ZEISS. During surgery, the image is used for intra-operative matching with the live eye image. All data needed is injected into the eyepiece of the surgical microscopes of the OPMI LUMERA® family3 from ZEISS.

    IOLMaster 700 Reference Image

    Reference Image

    For markerless toric IOL alignment

    The Reference Image allows a markerless toric IOL workflow. It references the patient’s astigmatic axis relative to his/her eye ball position using small blood vessels on the eye as landmarks. At the same time keratometry measurement is performed and displayed on the ZEISS IOLMaster 700. Both reference image and keratometry data are transferred to the ZEISS CALLISTO eye® computer-assisted cataract surgery system. All data needed is injected into the eyepiece of the surgical microscopes of the OPMI LUMERA® family from ZEISS.
