    Keratoconus screening and other applications
    Easy database operation
    Multilingual operation
    Comprehensive software

    Corneal Topographer Continues to Set the Standard for Resolution, Accuracy & Corneal Coverage

    TMS-4N has the comprehensive software: Single, Dual, Multiple and you can even customize your own map with favorite scale, map type and so on. Fourier Analysis provides you the refractive information with Spherical Equivalent, Regular Astigmatism, Asymmetry and Higher order irregularity. Fourier Analysis provides the refractive information with 3mm and 6mm diameter range. The software applications, Klyce Statistics, Enhanced Height and Height Change Maps are also available.
