    Each averages just over $15K each, so yes a huge investment. OptiKam is half the price and will do the same thing. Here's my summary...

    Will wow and impress technology driven patients
    Very professional feel to the practice
    Great for dispensing premium FF personalized PALS
    Extremely accurate measurements - down to 1/10th mm for PD's and seg height
    Will increase dispensing time per patient, not decrease due to many inputs required - so great for high average sale low volume practice
    Training and support is an absolute must to operate properly, however I don't find any of these systems to be very reliable due to technical computer software glitches

    Whenever i hear claims for digital centrattion systems like the one above, I am prompted to ask:

    "Against what benchmark is this claim for every accuracy and valid precision being made?
    How is the accuracy being vetted?

    Further...even if the accuracy is validated, is this level of precision comprimosed during the rest of the fabrication chain, or through subsequent frame adjustments or common misaliognments?"

    Discussion.

    There have been a few studies published evaluating the repeatability and reproducibility of video centration devices, including ZEISS systems, most in European trade journals. A Google search might turn some up.

    Further...even if the accuracy is validated, is this level of precision comprimosed during the rest of the fabrication chain, or through subsequent frame adjustments or common misaliognments?"
    Probably not, which makes it all the more important to improve accuracy wherever possible along the "fabrication chain" in order to minimize the propagation of error...

    Best regards,

    Speedier, and slightly more impressive looking.

    We're thinking of getting the Visureal measuring device with a Hoya tracer... apparently this can then calculate the exact thicknesses of different lenses ready for consultation with the patient. Is anybody using this system at present, and is it as good as it sounds?

    I use the Optikam in my office daily and have found it to be extremely accurate and would recommend it. It cost only about 8,500.00 and when I compared it to other dispensing systems, I found it to be the most impressive and be the best value. As Barry mentioned, accurate measurements alone will not guarentee accurate glasses but the more precise you start out with the better off you will be if you maintain those measurements through the rest of the fabricating and dispensing process.
