    Is there a device that can determine in precise value the unknown
    base curve of gas permeable contact lens?

    How do they manufacture gas permeable contact lens in the laboratory?
    Do they get a blank and then grind the required base curve, diameter
    and diopters. Or do they receive blank lens with already given
    base curve and produce the required diopters out of it?

    How accurate can they make the base curves of gas permeable contact

    Yes. Your fitter should have one.
    Usually the first option.
    Within 0.01mm.
